## Abstract

In this paper, based on chaos theory and dynamic system simulation, a dynamic model of a relational leadership system with pressure factors is established and simulated. The study found that the excessive self-leadership and the relational leadership cannot effectively improve the leadership effectiveness of leaders. In addition, with the adjustment of the self-leadership adjustment coefficient, leadership effectiveness will change from a stable state to a chaotic state. Only by adopting limited rational decision-making strategies in multicycle decision-making can leaders maintain a high level of leadership effectiveness. Previous research mainly focuses on the theoretical analysis of the complexity of the leadership system or the issuance of questionnaires, but seldom on the dynamic complex process of the leadership system. This study reveals the complexity and chaos characteristics of the dynamic evolution of the multifactor relational leadership system, puts forward the relational leadership theory and the complex leadership theory under the influence of pressure, and makes some suggestions on how to improve the leadership effectiveness under the complex environment. The research results are of great significance to theoretical innovation and practical application.

## 1. Introduction

Leadership reflects a person’s ability to make full use of surrounding resources to solve problems at the minimum cost and improve the efficiency of the whole team in a specific environment. The level of leadership often has a direct impact on an enterprise’s internal cultural environment and the future strategic development policy. An excellent leader can always make the most appropriate decision at the most appropriate time to maximize his leadership effectiveness. However, with the continuous update of science and technology and the deepening of global integration, the environment of leaders is constantly changing and the challenges they face are increasingly severe. Therefore, leaders not only need to have a more comprehensive understanding of the components of leadership but also need to further improve their leadership on this basis. Therefore, the study of leadership becomes very important.A central topic of leadership research is the influence of leadership style, the attitude patterns held by leaders, and the behaviors they exhibit [1, 2]. A leader’s leadership consists of a series of elements, including both environmental factors and personal factors. The environmental factors include the working conditions and team atmosphere, while the personal factors reflect the leader’s own ability. At the same time, because of the differences in these factors, leaders are divided into different types. In China, for example, leaders are often divided into the traditional paternalistic leader and transformational leader [3]. The traditional paternalistic leadership includes the following three types: servant leader, ethical leader, and authentic leader [4]. In order to better understand the leadership level of different types of leaders, Judge [5] studied the relationship between transformational, transactional, and passive avoidance leadership and leadership effectiveness. Sheraz [6] explored the relationships between ethical leadership and transformational, transactional leadership, and organizational citizenship behavior. However, with the deepening of research, many scholars combine leadership with complexity. Among them, Olalere [7] found through research that using the complex leadership model enables leaders to better understand the complex leadership crisis.In addition to the classification of different types of leaders, in recent years, many scholars have conducted systematic studies on the specific implementation of leadership. On the basis of summarizing relevant leadership literature, Morgeson et al. [8] focused on the leadership process within the team and described how team leadership was generated from four different sources inside and outside the team, so as to finally achieve the purpose of guiding and regulating leader behavior. Oc [9] comprehensively described the leadership situation by referring to Johns’ category framework and systematically reviewed the existing theoretical framework and empirical results of background influence. Derue et al. [10] solved the problem of integrating research contents in related fields by establishing an integrated trait behavior model of leadership effectiveness and tested the relative validity of leadership traits and behaviors. Yukl [11] discusses the limitations and potential extensions of hierarchical taxonomies and proposes research proposals for improving effective leadership behavior.Complexity is an important feature of the leadership system [12]. In recent years, scholars have gradually introduced complexity theory [13, 14] into leadership science, studying the structural complexity, process complexity, and application of leadership systems from different perspectives. Hernandez et al. [15] pointed out that the leadership system consists of leader, context, followers, collectives, and dyads five dimensions from the perspective of leadership status. Li and Mao [16] believed that the main elements of the leadership system are leader, subordinate, leader-subordinate interaction, and environment. Hooijberg et al. [17] reviewed the research in the field of cognitive, social, and behavioral complexity and proposed the Leaderplex Model. Uhl-Bien and Marion [18] studied the complexity of leadership in the form of bureaucratic organization and constructed a mesomodel of the theory of complexity leadership that includes administrative leadership, enabling leadership, and adaptive leadership. Hannah et al. [19] believed that leadership complexity is composed of static complexity and dynamic complexity. Static complexity is composed of the heterogeneity of groups or teams in the cognitive, social, self, and emotional fields.The relationship between leaders and subordinates is always in a dynamic game process [20], which needs to consider the complex game situation in the short term [21], medium term [22], and long term [23]. Lord Xu and Ma [24] pointed out that leadership complexity includes both static and dynamic aspects. Static complexity involves general, social, ego, and emotional complexity. Based on the development law and endogenous logic in the real situation, dynamic complexity is created through the interaction of psychological processes new complex aspects. Uhl-Bien et al. [25] pointed out that the theory of complexity leadership is a leadership framework that enables the learning, creativity, and adaptability of the complex adaptive system (CAS) in knowledge production organizations. It includes three entangled leadership roles: adaptive leadership, administrative leadership, and enabling leadership. Uhl-Bien et al. [26] further pointed out that, in a complex adaptive system that transforms from old order to new order, entrepreneurial leadership produces innovation and growth; operational leadership transforms innovation into new adaptations; sexual order improves performance and results; and empowering leadership can open up adaptive spaces to ensure the continued viability and adaptability of the organization. Lichtenstein et al. [27] formally proposed the complexity leadership theory, thinking that leadership is an emergency and a result of interaction between components. Hogue and Lord [28] used complexity theory to incorporate existing gender bias explanations into a comprehensive model of leadership gender bias, which is used to understand how gender bias occurs throughout the leadership process and affects women.In addition, leaders often carry out activities in a dynamic system in real life [29], so it is very important to combine leadership with a dynamic system [30]. Schneider and Somers [31] examined the leadership process in complex adaptive systems. They concluded that leaders indirectly influenced the organization through the intermediary variables of organizational identity and social movement and proposed to use dynamic system simulation and artificial neural networks as further development and testing of complex adaptive systems. Osborn and Hunt [32] criticized the idea that organizations were on the verge of chaos in complex adaptive systems and would exhibit “free order” behavior. They regarded organizations as a hierarchical structure may be guided by a collective to build a bottom-up structure to improve the organization’s long-term effective power system. Wolfgramm et al. [33] constructed a sustainable interaction dynamic interaction (DIAL) model and analyzed the dynamic interaction process among the four sustainable leadership components of habit, imagination, learning, and judgment. Baltaci and Balci [34] defined complex leadership as an adaptive mechanism developed by complex organizations under the new conditions required by the information age, which is specifically composed of executive leadership, adaptive leadership, and action-centered leadership. Cardiff et al. [35] believed that human-centered leadership was a complex, dynamic, relational, and background practice aimed at enabling leaders and employees to achieve self-realization, empowerment, and well-being. Plsek and Wilson [36] found that treating an organization as a complex and adaptive system can form a new and more effective management method in the healthcare organization. Those who seek to change the organization should harness such principles as generative relationships, minimum specification, the positive use of attractors for change.Based on the above research, the current research on the emerging leadership theory of complexity leadership is still at the exploratory stage. In terms of research methods, there are many qualitative studies and a few quantitative studies. No one has yet adopted chaos theory and dynamic system simulation to analyze the dynamics of the leadership system complexity; no one has comprehensively studied the complex interactions and specific internal mechanisms between leadership, followership, Leader-Member Exchange (LMX), leadership situation, and leadership effectiveness based on the CAS perspective and put forward targeted application suggestions. Therefore, it is time to solve the problem of developing and testing a full-factor leadership model based on the complex theory proposed by Schneider and Somers [31] and other scholars.Therefore, based on the current research progress of leadership, combined with chaos theory and complex dynamic system simulation, this paper established a dynamic model of relational leadership system with pressure factors, to further analyze the interactive relationship and internal mechanism in the leadership system and put forward effective suggestions to help leaders improve leadership effectiveness.


## 2. The Model

### 2.1. Model Building

Based on previous research results, we believe that the relationship leadership system consists of leaders, followers, Leader-Member Exchange (LMX), leadership situations, and leadership effectiveness. A relationship leadership dynamic system diagram is shown in Figure1. Leadership and followership are the most dynamic elements in the relational leadership dynamic system; this paper selects leadership and followership as the main influencing factors among multiple factors which affect leadership effectiveness and analyzes the influencing process in the leadership situation. The leadership situation is determined by three independent variables : favor, social circle, reputation; the leadership includes four independent variables: cognitive ability, cohesion, moral quality, and achievement motivation; and the followership includes five independent variables: aggressive spirit, cognitive perception, executive skills, influence, and relationships. According to the relational leadership theory proposed by Uhl-Bien [37], leadership is subdivided into self-leadership (including achievement motivation and moral quality) and relational leadership (including cognitive ability and cohesion) from the entity perspective and the relationship perspective. Among them, self-leadership highlights the individual orientation of the leader’s achievement motivation and moral quality while relational leadership highlights relational orientation of the leader’s subject-object cognitive relationship and the LMX relationship between the leader and the follower. This paper aims at providing a basis for leadership decisions by establishing a relational leadership dynamic system model, analyzing the complex dynamic behavior between leadership effectiveness and influencing factors, and then performing numerical simulation through MATLAB and Mathematica, using bifurcation graphs and exponential graphs to analyze the complex dynamic characteristics of the relational leadership dynamic system.Figure 1

### 2.2. Variable Setting (Interaction)

In the following sectors, we are going to investigate the relationship between leadership effectiveness and influencing factors, and accurately establish the mathematical model of the relational leadership dynamic system. Before modeling, first, some reasonable assumptions for each variable are listed here:(1)
During a specific leadership period, the Leader-Member Exchange (LMX) is relatively unchanged(2)
Leaders and followers take limited rational decisions(3)
Self-leadership and relational leadership can be adjusted through education and trainingAbove these assumptions, the relationship R is used as an implicit variable rather than an independent variable when constructing a mathematical model. It is an important foothold for studying the relationship leadership system. One can propose effective and practical leadership strategies by studying the relationship between leadership effectiveness and its influencing factors to improve leadership performance. As mentioned earlier, it needs to establish a mathematical model of the relational leadership dynamic system. According to the characteristics and actual situation of the relationship dynamic system, the leadership situation, leadership, and followership include multiple subvariables. The relationship is as follows.According to the characteristics of the relational leadership dynamic system, let the leadership situation beS (including three subvariables of human feelings, circles, and face); let the leadership be L (including four subvariables of cognitive ability, achievement motivation, cohesion, and moral quality), and let followership be F (including five subvariables of influence, cognitive perception, relationship skills, enterprising spirit, and executive skills); let leadership effectiveness be P (the result of the combined effects of L, F, and S).We build a mathematical model of multifactor driven relational leadership dynamic system, in whichm represents the leader’s self-leadership coefficient, d represents the relational leadership coefficient, and E1,E2,E3,E4 all have negative effects.The variables and parameters to be used in this paper are listed in Table1.Table 1
The notations used in this work.

Among them, the cognitive ability and cohesion are mainly affected by the relationship coefficient of leadership and realize the achievement motivation is affected by the leader’s self-leadership coefficient, while morals by internal and external two factors work together, so a leader in cognitive ability, and the stronger the cohesion of the team, the greater the motivation of self-value realization, and the higher the level of morality, the stronger its leadership.According to the results of existing research, leadership has an impact on followership through LMX, and leadership has an impact on leadership situations. Therefore, the leader’s self-leadership coefficientm and the relational leader coefficient d will both affect the followership and leadership situation accordingly. At the same time, basic leadership effectiveness is influenced by leadership, followership, and leadership situations:(2)F=a2+F1m+d+F2d+F3d+F4m+F5m−E2,(3)S=a3+S1m+Sm+d2+S3m−E3,(4)Pb=a4+d1L+d2F+d3S−E4,whered1=d,d2=m,d3=m+d.Similar to equation (1), equations (2)-(3) refer to the following ability and the influence of the leadership by its constituent elements, based on the different degrees of influence of internal and external environment on leaders. Take leadership as an example. Leadership is mainly affected by external factors such as the leader’s face and affinity, so the leader’s relationship leadership coefficient plays an important role in a number of factors. Equation (4) represents the main components of basic leadership effectiveness, including leadership, leadership situation, and followership.The final leadership effectiveness of a leader not only includes basic leadership effectiveness but also is affected by certain spiritual elements. A leader produces a base level of effectiveness based on the effectiveness of his leadership. However, with the increase of the effectiveness of leaders, the working pressure of leaders will increase. When the pressure exceeds a certain value, it will have a negative impact due to emotional fluctuations. On the contrary, it will have a certain positive effect. Therefore, according to equations (2)–(4), the final leadership efficiency of leaders is shown as follows:(5)P=αPb+εPb−Bβ.By equation (5), we know the final leadership effectiveness is made up of two parts: one part is based on leadership effectiveness into part of the final performance and the other part is the ultimate performance of the pressure of leadership effectiveness transformation; namely, when a leader’s leadership effectiveness is greater than the pressure line B, it will produce negative effects, and when its leadership effectiveness is less than the pressure line B, it will produce a positive effect.

## 3. Model Solution

To reflect the influence of a single parameter on leadership effectiveness, the self-leadership coefficientm and the relational leadership coefficient d are selected as important parameters. The partial derivative of the leadership effectiveness expression is obtained respectively to obtain the partial derivative equations of the two parameters and draw a graph of the influence of self-leadership coefficient m and relational leader coefficient d on leadership effectiveness in a single event. The partial derivatives of m and d for leadership effectiveness are shown as follows:(6)∂P∂m=a2−E3−E2+a3+F2d+F3d+dL2+L4+F4m+F5m+F1+F4+F5m+F1d+m+mS1+S2d+m+mS3+S1+S2+S3d+mα+βε,(7)∂P∂d=a1−E3−E1+a3+L1d+L3d+dL1+L3+L4+mF1+F2+F3+mL2+L4d+m+mS1+mS3+2d+mS2α+βε.Noticed that the second-order partial derivative ∂2P/∂m2 = 2α (F1 + F5 + S1 + S2 + S3) > 0, ∂2P/∂d2 = 2α(L1 + L3 + L4 + S2) > 0, the equation has a maximum. Through partial derivation of m and d for leadership effectiveness P, and let ∂P/∂m=0,∂P/∂d=0, we can obtain the optimal value of self-leadership coefficient m∗ and relationship leadership coefficient d∗ in the leadership context, full details are given in Appendix.Based on equations (6) and (7), we have the following proposition.Proposition 1.
In the leadership effectiveness system, the gradient value of self-leadership coefficientm and relationship leadership coefficient d is independent of the limiting value of stress B and linearly related to α, ε, and β.Proposition 2.
The optimal value of self-leadership coefficientm and relationship leadership coefficient d is independent of α, ε, and β. It is only related to the constituent elements in leadership situation S, leadership L, and followership F.In a single cycle, the leaders are faced with a lot of affairs, and it is not possible to explore what kind of leadership the leader should adopt from the analysis of a single transaction. This paper believes that leaders will make changes to the next leadership style based on the impact of the previous leadership style on leadership effectiveness. Here, the method of limited rational analysis is introduced. We assume that the leader does not fully understand the leadership effectivenessP and cannot analyze the change of the leadership effectiveness P from an objective perspective, which means the leader’s judgment on the leadership effectiveness P has certain limitations. According to the multifactors driven relational leadership dynamic system, we establish the following Markov chain model. gii=1,2 represents the self-leadership adjustment factor, the specific model is as follows:(8)mt+1=mt+g1mt∂Pt∂mt,dt+1=dt+g2dt∂Pt∂dt.By the previous equation, we know, in the periodt, when leaders of the marginal leader’s self-leadership coefficient and the marginal relational leadership coefficient are greater than 0, the leader will continue the current decision in the period t + 1, and when leaders of the marginal leader’s self-leadership coefficient and the marginal relational leadership coefficient are less than 0, the leader will change its decision in the next period.


## 4. Numerical Simulation

### 4.1. Static Simulation

To explore the influence of self-leadership coefficientm and relational leadership coefficient d on leadership effectiveness, we conduct a numerical simulation of the system:(9)a1=2.47;a2=0.5;a3=0.5;a4=0.5;E1=0.2;E2=0.2;E3=0.12;E4=0.12;F1=0.1;F2=0.6;F3=0.8;F4=0.8;F5=0.3;S1=0.295;S2=−1.43;S3=0.02;L1=0.15;L2=0.2;L3=0.2;L4=0.2;α=0.7;ε=0.5;B=0.3;β=0.3.We plot the effects of self-leadership coefficientm and relational leader coefficient d on leadership effectiveness in a single event. The specific simulation results are shown in Figure 2.Figure 2
Relationship between self-leadership coefficientm and leadership effectiveness P.As can be seen from Figure2, with the increase of self-leadership coefficient m, the leadership effectiveness continues to decrease, which means that a single-handed leader will do harm to the whole organization. However, with the increase of self-leadership coefficient m, the decline rate of leadership effectiveness P gradually slows down.Next, we will conduct relevant research on the relationship between the relationship leadership coefficientd and leadership effectiveness P, as shown in Figure 3.Figure 3
Relationship between the relationship leadership coefficientd and leadership effectiveness P.Figure3 shows that, with the increase of the relationship leadership coefficient d, the leadership effectiveness will increase. When d is approximately equal to 0.9, the leadership effectiveness peaks, but when d is greater than 1, the leadership effectiveness will gradually decrease. That is, when the relational leadership coefficient is large to a certain extent, leadership effectiveness no longer rises, but declines. This result is also consistent with the actual situation.Figures2 and 3 show the influence of changes in the self-leadership coefficient m and the relationship leadership coefficient d on leadership effectiveness. Next, we study the leadership effectiveness P when the self-leadership coefficient m and the relational leadership coefficient d change simultaneously. Here, we set the range of the self-leadership coefficient m and the relational leader coefficient d from −2 to 5, which allows us to observe the changes brought by these two parameters more intuitively.Then, we will show the relationship between self-leadership coefficientm and relational leadership coefficient d and leadership effectiveness P more intuitively, as shown in Figure 4.Figure 4
Relationship between self-leadership coefficientm and relational leadership coefficient d and leadership effectiveness P.As shown in the three-dimensional picture of Figure4, we can intuitively observe the influence of the self-leadership coefficient m and the relational leadership coefficient d on leadership effectiveness. From Figure 4, we can see that, with the constant increase of the self-leadership coefficient m and the relational leadership coefficient d, the leader’s leadership effectiveness first increases and then decreases. When parameter m and parameter d are both too high or too low, the leadership effectiveness of the leader is the lowest. When m=4.9,d=−0.5, there is the highest leadership effectiveness.


### 4.2. Dynamic Simulation

Leaders usually change their self-leadership coefficients and relational leadership coefficients according to the changes of leadership effectiveness. Next, this study analyzes the complex characteristics of self-leadership coefficientm, relational leadership coefficient d, and leadership effectiveness P by drawing bifurcation diagrams and LLE diagrams, as shown in Figures 5–8.Figure 5
The effect of the adjustment coefficient on the leadership self-leadership coefficient and relational leadership coefficient.Figure 6
The effect of adjustment factors on leadership effectiveness.Figure 7
The effect of the adjustment coefficient on the leadership self-leadership coefficient and relational leadership coefficient.Figure 8
Influence of self-leadership adjustment coefficient on leadership effectiveness.From Figure5, we can see that the change of self-leadership adjustment coefficient g1 affects the leader’s self-leadership coefficient and relational leadership coefficient. In the overall complex dynamic system, when the self-leadership adjustment coefficient g1=0.16, the system goes into an unstable state. With the increase of the self-leadership adjustment coefficient, when g1=0.21, the values of m and d gradually enter into a chaotic state.From Figure6, we can see that, as the leader’s self-leadership adjustment system increases, leadership effectiveness first rises rapidly, then enters a stable state, and finally enters a chaotic state. Similar to Figure 5, when g1<0.21, the leadership effectiveness will be stable at 1.53, and the leadership effectiveness has been rapidly increasing until then. However, after entering an unstable state, the leadership effectiveness is often higher than that in a steady-state.Figure7 is similar to Figure 5, we can see that the change of self-leadership adjustment coefficient g2 affects the leader’s self-leadership coefficient and relational leadership coefficient. We find that when g2=1.07, the system enters a bifurcation. When g2=1.1, the system bifurcates again and enters chaos. Compared with the self-leadership adjustment coefficient g1, under the premise of stable leadership effectiveness, the self-leadership adjustment coefficient g2 has a large adjustment interval and enters an unstable state faster. The adjustment interval of coefficient m and coefficient d from an unstable state to chaotic state is very small.Similar to Figure6, we can see from Figure 8 that, as the leader’s self-leadership adjustment coefficient increases, the leadership effectiveness also rises quickly, then enters a stable state, and finally enters a chaotic state. When g2<1.07, the leader’s leadership effectiveness stabilizes at 1.53, which is the same as the adjusted steady-state value of g1. Similar to Figure 7, when g2=1.07, the leadership effectiveness diverges and enters an unstable state. When g2=1.1, the system bifurcates again and enters chaos. Under unstable conditions, compared with the leadership effectiveness adjusted by g1, the leadership effectiveness adjusted by g2 is lower than the stable leadership effectiveness.


## 4.1. Static Simulation

To explore the influence of self-leadership coefficientm and relational leadership coefficient d on leadership effectiveness, we conduct a numerical simulation of the system:(9)a1=2.47;a2=0.5;a3=0.5;a4=0.5;E1=0.2;E2=0.2;E3=0.12;E4=0.12;F1=0.1;F2=0.6;F3=0.8;F4=0.8;F5=0.3;S1=0.295;S2=−1.43;S3=0.02;L1=0.15;L2=0.2;L3=0.2;L4=0.2;α=0.7;ε=0.5;B=0.3;β=0.3.We plot the effects of self-leadership coefficientm and relational leader coefficient d on leadership effectiveness in a single event. The specific simulation results are shown in Figure 2.Figure 2
Relationship between self-leadership coefficientm and leadership effectiveness P.As can be seen from Figure2, with the increase of self-leadership coefficient m, the leadership effectiveness continues to decrease, which means that a single-handed leader will do harm to the whole organization. However, with the increase of self-leadership coefficient m, the decline rate of leadership effectiveness P gradually slows down.Next, we will conduct relevant research on the relationship between the relationship leadership coefficientd and leadership effectiveness P, as shown in Figure 3.Figure 3
Relationship between the relationship leadership coefficientd and leadership effectiveness P.Figure3 shows that, with the increase of the relationship leadership coefficient d, the leadership effectiveness will increase. When d is approximately equal to 0.9, the leadership effectiveness peaks, but when d is greater than 1, the leadership effectiveness will gradually decrease. That is, when the relational leadership coefficient is large to a certain extent, leadership effectiveness no longer rises, but declines. This result is also consistent with the actual situation.Figures2 and 3 show the influence of changes in the self-leadership coefficient m and the relationship leadership coefficient d on leadership effectiveness. Next, we study the leadership effectiveness P when the self-leadership coefficient m and the relational leadership coefficient d change simultaneously. Here, we set the range of the self-leadership coefficient m and the relational leader coefficient d from −2 to 5, which allows us to observe the changes brought by these two parameters more intuitively.Then, we will show the relationship between self-leadership coefficientm and relational leadership coefficient d and leadership effectiveness P more intuitively, as shown in Figure 4.Figure 4
Relationship between self-leadership coefficientm and relational leadership coefficient d and leadership effectiveness P.As shown in the three-dimensional picture of Figure4, we can intuitively observe the influence of the self-leadership coefficient m and the relational leadership coefficient d on leadership effectiveness. From Figure 4, we can see that, with the constant increase of the self-leadership coefficient m and the relational leadership coefficient d, the leader’s leadership effectiveness first increases and then decreases. When parameter m and parameter d are both too high or too low, the leadership effectiveness of the leader is the lowest. When m=4.9,d=−0.5, there is the highest leadership effectiveness.


## 4.2. Dynamic Simulation

Leaders usually change their self-leadership coefficients and relational leadership coefficients according to the changes of leadership effectiveness. Next, this study analyzes the complex characteristics of self-leadership coefficientm, relational leadership coefficient d, and leadership effectiveness P by drawing bifurcation diagrams and LLE diagrams, as shown in Figures 5–8.Figure 5
The effect of the adjustment coefficient on the leadership self-leadership coefficient and relational leadership coefficient.Figure 6

The effect of the adjustment coefficient on the leadership self-leadership coefficient and relational leadership coefficient.Figure 8
Influence of self-leadership adjustment coefficient on leadership effectiveness.From Figure5, we can see that the change of self-leadership adjustment coefficient g1 affects the leader’s self-leadership coefficient and relational leadership coefficient. In the overall complex dynamic system, when the self-leadership adjustment coefficient g1=0.16, the system goes into an unstable state. With the increase of the self-leadership adjustment coefficient, when g1=0.21, the values of m and d gradually enter into a chaotic state.From Figure6, we can see that, as the leader’s self-leadership adjustment system increases, leadership effectiveness first rises rapidly, then enters a stable state, and finally enters a chaotic state. Similar to Figure 5, when g1<0.21, the leadership effectiveness will be stable at 1.53, and the leadership effectiveness has been rapidly increasing until then. However, after entering an unstable state, the leadership effectiveness is often higher than that in a steady-state.Figure7 is similar to Figure 5, we can see that the change of self-leadership adjustment coefficient g2 affects the leader’s self-leadership coefficient and relational leadership coefficient. We find that when g2=1.07, the system enters a bifurcation. When g2=1.1, the system bifurcates again and enters chaos. Compared with the self-leadership adjustment coefficient g1, under the premise of stable leadership effectiveness, the self-leadership adjustment coefficient g2 has a large adjustment interval and enters an unstable state faster. The adjustment interval of coefficient m and coefficient d from an unstable state to chaotic state is very small.Similar to Figure6, we can see from Figure 8 that, as the leader’s self-leadership adjustment coefficient increases, the leadership effectiveness also rises quickly, then enters a stable state, and finally enters a chaotic state. When g2<1.07, the leader’s leadership effectiveness stabilizes at 1.53, which is the same as the adjusted steady-state value of g1. Similar to Figure 7, when g2=1.07, the leadership effectiveness diverges and enters an unstable state. When g2=1.1, the system bifurcates again and enters chaos. Under unstable conditions, compared with the leadership effectiveness adjusted by g1, the leadership effectiveness adjusted by g2 is lower than the stable leadership effectiveness.


## 5. Chaos Control

From the conclusions obtained in the previous section, it has been realized that when the self-leadership adjustment coefficient is too high, the self-leadership coefficient and relational leadership coefficient will enter an unstable state, and eventually chaos will appear. If leaders fail to make correct decisions to adjust their leadership, leadership effectiveness will also be affected and fluctuations will occur, which ultimately leads to poor leadership performance. Considering the influence of the chaos on leaders, it is necessary for leaders to effectively control chaos to ensure the correct decision-making of the leadership, so as to stabilize the leadership effectiveness and benefit the system. According to the characteristics of the entire decision-making process, this study adjusts the decision-making method to control chaos, so the delay control method is considered. The core idea of the delay control method is to feedback the system after the system delays. In other words, this study observes that some of the information is the output signal of the system. When deciding the next cycle, we consider the decision in periodt. Therefore, the dynamic adjustment model is as follows:(10)mt+1=mt+g1mt∂Pt∂mt+gmt−mt+1,dt+1=dt+g2dt∂Pt∂dt+gdt−dt+1.We set the parameters as(11)a1=2.47;a2=0.5;a3=0.5;a4=0.5;E1=0.2;E2=0.2;E3=0.12;E4=0.12;F1=0.1;F2=0.6;F3=0.8;F4=0.8;F5=0.3;S1=0.295;S2=−1.43;S3=0.02;L1=0.15;L2=0.2;L3=0.2;L4=0.2.Since the adjustment parameters of each decision variable in the system are different when entering chaos, we set different adjustment parameters for different decision variables here. For variablesd,p, and m, we set the adjustment parameters as follows: g1=0.28,g2=0.35. In this case, the original system is in a chaotic state. This study introduces control parameters g and adds delayed feedback to the decision signal. Through numerical simulation, we draw a bifurcation diagram with increasing control parameters g, as shown in Figure 9.Figure 9

(a)(b)(c)From Figure9, we can see that adding delayed feedback to the leadership decision eliminates the instability of the system effectively. When g is very small, the system is chaotic. With the increase of the control parameter g, the leaders’ self-leadership coefficients and relational leadership coefficients of the system gradually stabilize. When g>0.3, the leadership effectiveness also changes with the change of the two coefficients and finally breaks away from the chaotic state and reaches a stable state. At that time, the entire system remains stable and leaders could make effective decisions.In Figures5–8, with the increase of adjustment parameters, the leaders’ self-leadership coefficients, relational leadership coefficients, and leadership effectiveness gradually enter into a chaotic state. However, in Figure 9, the chaotic state is controlled with the increase of control parameters and finally returns to a stable state, which also shows that the delay strategy can prevent the excessive adjustment of the leaders’ self-leadership coefficients and relational leadership coefficients by leaders, prevent the instability of leadership effectiveness, and enhance the stability of the enterprise. It also can be concluded that delaying control based on the leader’s self-leadership and relational leadership is a good method of controlling the system.


## 6. Conclusion

This paper studies the influence of leaders’ self-leadership coefficient and relational leadership coefficient on the leadership effectiveness in single-cycle and multicycle leadership situations, to analyze how leaders should make decisions in business decision-making. First of all, this paper constructs the final leadership effectiveness model by analyzing the components of leadership that influence leaders’ decisions and combining spiritual factors. Then, the influence of parameters in static and dynamic systems is analyzed by numerical simulation. Through research, we reach the following conclusions:(1)
When the self-leadership coefficientm increases, the leadership effectiveness will gradually decrease, but the reduced gradient will decrease. This shows that the mere increase of self-leadership is not conducive to the improvement of leaders’ leadership. When self-leadership reaches a certain height, leadership will no longer decrease.(2)
Similarly, with the relationship leadership coefficientd, the leader’s leadership first increases and then decreases. This indicates that relatively small relational leadership is conducive to leaders’ decision-making, but too much emphasis on relational leadership will have adverse effects on leadership.(3)
Leaders use limited rational expectations to make changes in the leadership effectiveness in business decision-making to show that leaders use limited rational decision-making strategies in multicycle decision-making so that leaders can maintain high leadership effectiveness in decision-making. At the same time, when making adjustments to bounded rational decision-making, the system needs to be in a stable state. Once it enters a chaotic state, the leader’s decision will appear in a chaotic state that cannot predict the optimal decision. And this should be avoided.(4)
The delay control can control the unstable and chaotic state of leadership in the dynamic system and make it gradually enter the stable state. This also shows that the combination of predicted leadership and current leadership is conducive to the leader’s decision-making to keep the enterprise or market stable.This paper takes into account various leadership components and spiritual factors, which has certain reference value in the field of leadership research. But the purpose of this article is to describe a comprehensive leader. In real life, there are many types of leaders in an enterprise, and different leaders have limited leadership competition. Future research should focus on the study of leaders of all types.
