## Abstract

The construction of the economic management information system ensures the flow and sharing of information, business coordination, and scientific decision-making between economic functions. Therefore, project construction is absolutely necessary and urgent. Project management has achieved significant results in terms of shortening project time and reducing management costs. Information system is an important model information structure in artificial intelligence. This paper focuses on the design of a fusion method for economic management problems based on decision information systems. This paper summarizes the value of the whole project through the research on the project management of the economic management information system. The results of this study show that when the threshold is fixed, the information granularity Gtheta and rough entropy (Er) theta decrease monotonically with increasing attribute subset cardinality. Meanwhile,θ-information granularity Etheta and θ-information entropy Htheta monotonically increase with the increase of attribute subset cardinality, which indicates that when attribute subset cardinality increases, the uncertainty of the information system decreases.

## Body

## 1. Introduction

In recent years, the international economic downturn and domestic difficulties have overlapped with each other, and the unstable and uncertain factors in economic operation have increased [1, 2]. Under such circumstances, it is particularly important to accurately judge the economic situation and take effective measures in a timely manner [3]. The importance of removing redundant data without changing the data structure, such as attribute approximation and decision rules, and how to mine potentially useful information [4–8]. A large amount of data have been generated in all fields of human production and life [9–12]. These data types are becoming more and more complex in type and are still expanding in size, resulting in high-dimensional massive data information of complex types and formats [13–15]. This thesis takes economic management information system project management as the research object, first carries out the theoretical review related to project management, then a brief overview of the economic MIS is given, and on this basis, the elements of the economic MIS are analyzed. The human resource management, risk management, and communication management of this system development project are elaborated, and finally, the value of the overall project is summarized.Integration development is subject to realistic conditions and in the form of market economy, which brings its complexity. In a competitive market, whether an enterprise grasps and effectively handles information in a timely manner is the key to success or failure. The power of information technology, represented by computer technology, lies precisely in its ability to change product development, product production processes, disrupt industrial structures and economic environments and break the competitive balance. The application of information technology in the field of production management has produced management information systems and decision support systems, which can greatly improve the ability of enterprises to process information and promote the effective use of human resources and capital, so as to realize the optimal allocation of resources, reduce intermediate losses, and enhance the market competitiveness of enterprises. With the help of information technology, the study of integration methods, manufacturing enterprise management informationization, and scientific decision-making has practical significance and value.The innovations of this paper are as follows: (1) an object set-based reduction algorithm is established for property reversion in the context of set-valued decision-making message systems. Based on this, a kind of distinguishable object is constructed. The set attribute reduction algorithm uses the set of distinguishable object sets, calculates the minimum disjunction paradigm to solve all the distribution reduction and maximum distribution reduction, and validates the effectiveness of the algorithm by using case analysis. (2) A heuristic dynamic attribute reduction algorithm is proposed for the dynamic increase of attribute sets in the set value determination message network by introducing the concepts of conditional information quantity and attribute importance when the new attribute set is added to the decision information. In the system, the algorithm can use the attribute reduction result of the original system to quickly update the attribute reduction after the attribute set is added, reversely eliminate the redundant attributes that may exist in the updated attribute reduction, and maintain the knowledge acquisition, it further analyzes the effectiveness and feasibility of the algorithm through case verification. (3) For the dynamic increase of objects in the set-valued decision information system, first, the influence of new objects on the original knowledge in the information system is studied; second, the update mechanism of the new objects on the distribution reduction is analyzed and an increment is proposed; third, quickly update the distribution coordination set, obtain the attribute reduction by calculating the minimum disjunction paradigm, and the algorithm’s viability, as well as efficiency, is analyzed by example verification.The exposition of the article is structured as follows:In the first part, the background and significance of the study are first explained, followed by an overview of the chapter arrangement and main contents.The second part is a summary of relevant theories. The concept of project, the concept of project management, and the development of project management in China are reviewed.In the third part, an overview of the economic management information system project is given. Mainly from requirements analysis and business analysis, the overall objectives, milestones, and design plan of the project are proposed, and the database, application platform, storage system, and network system are described in detail, which reflects the general outline of the project.Finally, a summary and outlook of the economic management information system project are presented.

### 2.1. Related Work

The message based on information is an essential artificial intelligence model. It is an important research content of information system. As an evaluation tool, it is an important research topic of machine learning. Therefore, Shankaranarayanan et al. have suggested that the design and configuration of these systems must reflect an assessment of the cost-benefit trade-offs of meeting technical and functional requirements. In their research, they developed a framework for designing marketing information systems for economically driven evaluation programs. The architecture protects against the penalties associated with delayed implementation by defining different design strategies that take into account the uncertainty of exploitation, the variations in cost, as well as the performance between technologies. Their evaluation highlights the conditions under which this design strategy outperforms other design strategies [16]. The Canellas et al. study found that decision-makers were often asked to provide incomplete information as a basis for their decisions. The right decision is determined by the higher overall rating option. Efforts are measured as a count of the basic information processes required for each strategy to make a decision. The results show that (1) the matching of situational features and natural decision-making makes the accuracy of the heuristic strategy the closest to the analysis strategy; (2) the variability of the heuristic strategy's distribution of effort requirements for each total information level suggests that it is not always as beneficial as previously shown; (3) the trade-off between information imbalance and total information provides new guidance for the restrictive design of decision support systems and the guidance of incomplete information scenarios and ideas [17]. The watershed information system (RBIS) proposed by Franziska and Sven, not only meets the needs of a research project but also focuses on generic functions, scalability, and adherence to standards common in interdisciplinary environmental research [18]. Laslo and Gurevich proposed a simulation-based decision support system to manage the IT portfolio. “Optimization” projects are identified by constraining time and cost plan alternatives at decision points and evaluating updated opportunity portfolio budgets for alternative project options therein. These “optimize” as well as the evaluation are stochastic processes based on Monte Carlo calculations. Stochastic processes are appropriate because they can analyze information at much lower layers and provide results that are more precise than the inadequate deterministic processes that mainly produce erroneous results [19]. The above-mentioned related research results mostly evaluate the impact of incomplete information, or the management evaluation of a certain product, and the evaluation angle of project management is relatively single.To help compare existing models in the literature and highlight their contributions to the literature, the literature analysis in Table1 is enumerated;Table 1

### 2.2. Information System Theory

Currently, the attribute simplification of rough set model is mainly for static information systems. In the era of big data, a large amount of real-time data are added to the information system all the time. The dynamic change objects of data in information systems tend to increase with time. It is more difficult to extract useful knowledge from dynamic data by static attribute approximation methods in the traditional environment. Therefore, it is of great practical importance to study incremental update methods for rough set data. The incremental update method can make full use of the original knowledge and correlate the new knowledge with the original knowledge. It only needs to update part of the changed data and can acquire new knowledge without recalculating the original knowledge, which can effectively improve the efficiency of knowledge updating.Rough set theory in the classical sense is realized by equivalence relations. It can handle discrete data in information systems without missing data, but not continuous data, and considers knowledge as having classification capability. The more accurate the knowledge is, the stronger the classification capability is and the granularity of the classification becomes smaller. Knowledge representation is expressed in a centralized manner as an information system. If this information system contains both conditional and decision attributes, it is called a decision information system or decision table. Rough set theory is a mathematically soft computing tool. It can effectively analyze and deal with uncertainty and incompleteness problems. It can handle practical applications to compute, analyze, process, and finally deal with data problems in information systems. In imperfect information transfer environments, it is not possible to use the classical equivalence relations of rough sets for division. However, in real situations, information systems do have incomplete and missing information, so it is necessary to use other extension relations to deal with complete information.SU,C is the information system, U is the set of targets, and C is the set of properties of terms. Vc=∪aecVa,Va=ax:x∈U be the domain of values in conditional property a, where a(x) represents values of items x below property a, x∈U, DT U,C∪D is the information network for decision-making, U is the set of objects, C is the set of conditional properties, d is the policy making, Vdx:x∈U is the value range of d, and R is a binary relationship on U×U. This binary relationship can be obtained from a subset of attributes or from a decision, and the R obtained according to the different definitions is also different. In this book, let U be a finite set(1)RB=x,y:ax=ay,a∈B,B⊆C,and(2)xRB=y|xRBy,y∈U.Thus,U is divided under RB(3)URB=xRB:x∈U,[x] represents some basic set ofU. A lower limit of a rough set and an upper limit can be defined by knowledge or definable sets, or approximated by elements or equivalence classes.(1)
Define formula (4), suppose U is the set of objects, A is the set of attributes, and U and A are finite sets.(4)x,y∈indp⇔∀a∈P,ax=ay,(5)indp=∩a∈pinda.SupposeU,A was an informative network and P⊆A, then the relation of equivalent ind(P) may then be specified asObviouslyLetU,A be an information system. If for each a;∈;A, Va;=; [0, 1], (property a determines a fuzzy set on U), then we call U,A Information system. If P⊆A, then U,P is a sub-information system of U,A.Example 1.
Table2 describes an information system for a car, where the object set U;=;{x1, x2, x3, x4, x5, x6, x7, x8, x9} and attribute set A;=;{a1, a2, a3}.(2)
Fuzzy information structure in information systems(6)SR=SRxi,SRx2,…,SRxn.Given the fuzzy relationR on U, it can be regarded as a fuzzy neighborhood or information particle of point xi for any i,SRxi. The R structure is defined as
It can be seen thatRPGθ is the fuzzy T-equivalent relationship on the object set U. For any i, SRPGθxi can be seen, it is a fuzzy neighborhood of xi or fuzzy information particles.(7)SRPGθ=SRPGθx1,SRPGθx2,…,SRxn.
It could be regarded to be a vague particle architecture ofRPGθ. Therefore, SRPGθ can be regarded as the θ-fuzzy information structure of the sub-information system U,P.

To better compare the correctness of the system, the final score of the device of the system was compared with the score given at the end of the case, and the agreement was correct.The system was deployed on the network server for one month, and it worked well during the period. After the teachers and students of the lab log in, the modules were tested, and found that the average response time of each level of functions was less than 3 seconds. At the same time, the LoadRunner test tool is used for stress testing. Since the system is a dedicated system, the number of people on the line will not be particularly large. During the test, 100 users were simulated to access concurrently, and the correct user names and passwords were provided for the 100 simulated users. It was found that the system could be accessed normally. For operations that modify data, the correct rate of the database is also within acceptable limits.


#### 3.1.1. Overall Test

Because the system will give a score result for each plan to be evaluated. Therefore, if the system is not correct, then the re-improvement of each function design is futile. In this chapter, the data of this case are input into the system. If the final score of the equipment calculated by the system is consistent with the score given at the end of the case, the system is considered correct.


### 3.2. Experimental Data Collection

Communication information uses (1) interactive communication, through multiparty information exchange between conferences, telephone calls, instant messaging, video conferencing, etc., which ensures that the project team finally agrees on a certain issue. (2) Push communication, through mail, fax, log, news, memo, and other means to ensure that the information is received by the project team, but can not guarantee delivery or be fully understood. (3) Pull-type communication through the intranet, online courses, knowledge base, etc., requires the recipient of the information to access by itself, it is suitable for scenarios with a large amount of information and a large number of people. Management communication requires multilevel and multidirectional processing of project information, such as generation, collection, distribution, storage, retrieval, etc., according to the communication management plan formulated in the planning communication management process. This process must ensure that beneficial communication between the project teams is indeed achieved.For this stage of work, not only the completion of communication but also the communication information can be correctly understood by the other party and create opportunities for more in-depth information exchange. In particular, although some casual discussions can also be called meetings, in order to achieve better communication, the meeting recommends a formal way to determine the time, place, and meeting matters. The typical approach is to draw up a discussion item checklist and circulate in advance. During the implementation of this project, interactive communication is mainly used, and push communication is also used every day. In particular, it is necessary to explain that the project is complicated and the system is complicated.

## 4. Discussion

### 4.1. Risk Identification

Risk identification is the process of systematically predicting, identifying, and analyzing the causes of various risks that have not yet occurred and objectively exist. Risk identification is the most basic and important process in the risk management process. According to the analysis in Figure4, the main risks of this project are as follows.(1)
Organizational riskThe organizational risks mainly include the fact that the internal members of the organization have not reached an agreement on the objectives of the economic management information system, the senior management has not paid much attention to the project, the lack of knowledge and skills of the project participants, the lack of teamwork spirit, and the improper personnel incentive mechanism have led to the instability of the construction team, insufficient construction funds, resource conflicts with other projects, etc.(2)
Management riskManagement risks mainly include improper use of the basic principles of project management, inadequate project planning, unsatisfactory quality, unreasonable progress, and low resource allocation.(3)
Technical riskTechnical risks mainly include requirements for technical indicators that are too high at the beginning, frequent changes in technical standards, and uncertainties in the application of new methods and technologies.(4)
External risksExternal risks mainly include the following aspects. Due to changes in legal regulations, the situation of project stakeholders is often risky because it is difficult to control.Figure 4
Value function display.


### 4.2. Risk Assessment

As shown in Table3, risk assessment is to assess risk through qualitative analysis and rank the risks according to the degree of risk impact. In project management, we hope to quantify the risk as much as possible; that is, try to determine the probability of occurrence of various results. Risk analysis can be quantitatively analyzed through quantitative analysis of risks. This project is based on the expert decision-making method. Because the economic management information system is a relatively mature system from a commercial point of view, the entrusted development company has more development experience, staff training is in place, and project management has accumulated a large number of actual combat cases. Expert analysis and decision-making are more in line with actual needs. The experience of experts is generally credible in practical work. The requirements in the quantitative analysis of many project risks give different risk probabilities and different risk losses of several projects. The requirements for accuracy are not high, so the expert decision-making method is adopted. The results of quantitative analysis of project risks can be accepted in practice.Table 3
Decision information system analysis table.
a1a2a3a4a5a6x1(0.5, 0.7)(0.6, 0.3)(0.4, 0.2)(0.7, 0.6)(0.8, 0.5)(0.6, 0.5)x2(0.3, 0.7)(0.3, 0.7)(0.4, 0.8)(0.3, 0.4)(0.6, 0.8)(0.3, 0.7)x3(0.5, 0.4)(0.8, 0.1)(0.3, 0.9)(0.7, 0.4)(0.5, 0.8)(0.4, 0.8)x4(0.4, 0.7)(0.7, 0.9)(0.2, 0.5)(0.7, 0.8)(0.6, 0.4)(0.3, 0.8)From the surface of Figure5, the system risk is mainly from the users themselves. This risk can be communicated through project team members for risk control. The system implementation of this project is completed by highly professional development company project members, so the quality risk is better controlled. At the same time, during the development of the economic management information system, the project team members conduct quality supervision to ensure the project. In this project, the experts through the final analysis, it is concluded that the communication between technical and business personnel is difficult, the continuous change of users’ needs, and the lack of skilled personnel are the most important risk factors of the project. Therefore, finding a coping strategy that meets the actual situation to reduce the possibility of these risk factors and reduce the possible damage caused by these risks should be fully taken into account in project management.Figure 5
Fc-decision information system.


### 4.3. Risk Response

Project risk response refers to the process of developing effective programs, deciding, and taking countermeasures to increase opportunities and reduce threats for project objectives. It can be seen from Figure6 that after the risk assessment process, the risk response process is assigned to the risk responder responsible for the implementation of the risk response measures for confirming and implementing the funds. The risk prevention of this project mainly focuses on the risks brought by project organization, project management, and technology adoption.Figure 6

#### 4.3.1. Risks and Coping Strategies Faced by the Project Organization

The project construction and implementation team (including the overall group, engineering management team, technical team, information resource group, financial management team, and six groups) were established.


#### 4.3.2. Project Management Risks and Countermeasures

In order to ensure that the efficiency of project management reaches the prescribed level, specific and detailed project implementation plans need to be prepared, and advanced management systems and means should be applied to improve the project schedule control level. In order to avoid the problems of management and coordination of service providers in the process of project construction, the quality control of the whole process will be strengthened, and the project quality management regulations that suppliers should follow are clearly defined in the documents such as bidding documents and project contracts, and the scope of work of the project is clarified with preconditions, such as division of labor interface, restrictions, etc., and strict engineering supervision.


#### 4.3.3. Project Technical Risks and Countermeasures

Full implementation of the economic management information system. This project will improve the information system based on the existing regulations of the national twelve gold. Establish effective safety management rules and regulations.


### 4.4. Risk Control

As shown in Table4, risk control refers to various control measures for risks throughout the project, based on the project risk management plan and the actual risk of the project. Control communication is the process of monitoring and controlling communication throughout the project cycle, meeting the project team’s needs for all directions of information, and ensuring that information sharing among all participants is optimized at all times.Table 4
Data set comparison table.
Data setObjectFeatureEcoli3367Yeast14848Connectionist bench20860Control communication requires a certain method, and information management system is an important tool. The information management system shown in Figure7 provides a standard tool for the project manager to acquire, store, and release information on the cost, schedule, performance, etc. The project manager can use the software to integrate reports from multiple directions and to the project. The team distributes the results, and the results can be reports, spreadsheets, etc. In the process of controlling communication, expert judgment can be used to assess the impact of project communication. Expert judgment can come from consultants, experts, PMOs, stakeholders, etc., provided that the characteristics are accepted. Training or possessing specific knowledge, experts judged to take action or make necessary interventions in project communication, the ultimate goal is to achieve better communication and optimize information sharing. It is well demonstrated that project engineering implementation teams use information management systems to distribute cost, schedule, and performance information to the team, where the project management organization can make professional judgments and control communications to move in a better direction.Figure 7

## 5. Conclusions

Based on the local e-government network platform, this paper studies business application, information sharing, security, and other systems to ensure information flow sharing, business collaboration, scientific decision-making, government macro-control, and emergency response. The ability to stabilize the market has been further enhanced and providing an information guarantee for the provincial party committee and government to accurately grasp the province’s economic situation. The construction of economic management information system is carried out in combination with the local actual situation, and the project management of the economic management information system is taken as the research object, and the value of the whole project is summarized. From demand analysis and business analysis, the overall goals, phased goals, and design plans of the project are put forward. The research results provide certain help for improving work efficiency and increasing the accuracy and pertinence of data analysis. However, there are still some shortcomings in the actual construction and use process. For example, in the information acquisition stage, effective economic information cannot be quickly identified, and manual data screening and collection are still relied upon. In addition, the design of this paper fails to establish an effective connection with the big data analysis system. If the power of big data analysis is used, the operating efficiency of the system can be further improved.It is certain that in the future, the information management system is not only a technical means to improve office automation, but more importantly, in the implementation process of the information system, it will have a profound impact on the management thinking, management organization structure, and management methods of the enterprise. To understand the management ideas and management concepts contained in it, make corresponding adjustments to the organizational structure of the enterprise, and improve the quality of personnel, can the information system be successfully implemented and due power of the information system be exerted [20–23].
