Authors: Li‐juan Wang , Hong‐wei Wang , Xi‐chao Sun 
Published: March 2013

PurposeThe purpose of this paper is to research the influence of inflation and delay in payment on the inventory model on Weibull distribution and present a new method of inventory control model for fresh agricultural products.Design/methodology/approachThe previous researches deal with the inventory problems. However, these researches are based on deteriorating industrial products, so that the method for inventory model of agricultural products should be employed. According to agricultural products characteristics, the model assumes that deterioration is defined as fixed and demand is taken as Weibull distribution. An optimal order quantity and the minimum inventory total cost are formulated and solved under inflation and delay in payment.FindingsThe minimum inventory total cost and the optimal ordering quantity are convex with the length of the period with positive stock. When the delay period is longer than the length of the period with positive stock, the minimum inventory total cost and the optimal ordering quantity increase with permissible delay in payment increase and decrease with inflation rate increase, changing steeply with inflation rate and increasing permissible delay.Research limitations/implicationsThe market demand of fresh agricultural products is on two‐parameter Weibull distribution.Practical implicationsThe paper gives useful advice for agricultural supply chain managers.Originality/valueThe paper presents a new method of inventory control for fresh agricultural products.

Published: March 2013

PurposeThe purpose of this paper is to describe the complicated characteristics of the environment, the relationship between complicated organization and organizational transformation, and the coupling domino effect between the complication of external environment and organizational complexity by making conceptual systematic analysis.Design/methodology/approachThe relative stability and certainty of the organizational structure are being replaced by uncertainty and complexity. Organizational learning and its reform are becoming all the more important to gain organizational competitive advantage. This paper designs the system analysis method to discuss the complexity of organizational environment, the relationship between organizational complexity and organizational structure reform, and also the coupling effect of the complexity of external environment and that of the organization.FindingsIt is found that organizational learning, the ways of strategic reform, and the focal point must remain consistent under the complicated environment.Research limitations/implicationsThe main limitation is how to construct the mathematical models describing complicated characteristics of the environment.Practical implicationsThe paper contains very useful advice for human resource managers.Originality/valueThe paper focuses on the selection of learning patterns and strategic management of different organizational learning and the reform of organizational structure.

Published: March 2013

PurposeThe purpose of this paper is to present an approach which can evaluate the ability that successfully achieves command and control, both in qualitative and quantitative modes, to improve decision accuracy and speed, as well as construct an executable architecture for analyzing and verifying different decision projects.Design/methodology/approachBy defining command and control (C2) decision architecture and decomposing C2 decision processes into measurable subfunctions, measures and metrics will be associated with each of the lowest level decomposed functions, and will be used to provide support for performance evaluation. Both Markov decision process analysis and conditional probability (CP) logic are used for modeling the decision‐making process of course of action (COA). Meanwhile, an executable architecture constructed by Petri net is applied to logic structural verification and performance evaluation.FindingsThe paper presents an idea and methodology for net‐centric command and control decision‐making process analysis.Research limitations/implicationsThe paper describes and decomposes C2 decision processes for complex missions in uncertain environments.Practical implicationsThe paper could be an important reference of analysis and application in net‐centric command and control of decision making.Originality/valueThe paper combines methodology with qualitative methods (decision process decomposition), quantitative method (Markov decision process analysis and CP logic), as well as structural verification and performance evaluation.
Multifractal features of metal futures market based on multifractal detrended cross‐correlation analysis
Authors: Guo Yaoqi , Huang Jianbo , Cheng Hui 
Published: March 2013

PurposeRecently, many scholars have been paying more attention to studying the existence and application of multifractality. However, most researches concentrate on studying multifractal features of returns or volume separately, and ignore the correlation between them. The purpose of this paper, therefore, is to give an empirical test on multifractal features of price‐volume correlation in China metal futures market and then to conduct a comparative analysis from time and space dimensions, in order to better understand metals futures market behavior.Design/methodology/approachThis paper gives an empirical test by means of multifractal detrended cross‐correlation analysis (MF‐DCCA) approach, which is a technique employed in statistical physics to detect multifractal features of two cross‐correlated nonstationary time series.FindingsEmpirical results show that the price‐volume correlation in China metal futures market is multifractal and that long range correlation and non‐Gaussian probability distribution are the main reasons for the existence of multifractality. Also, a comparative analysis is conducted and it is found that although China metal futures market is becoming more and more effective, the effectiveness is lower than that in mature LME metal futures markets. The futures market still needs further development.Originality/valueThe paper's conclusions would help to understand the nonlinear dependency relationship and potential dynamics mechanism in price‐volume correlation.
Data output from Javascript
Authors: Andrew Alex M. 
Published: March 2013

PurposeThe purpose of this paper is to review the advantages of the Javascript programming language for demonstration programs. A major disadvantage is the difficulty of exporting data from such programs, felt particularly when graphical output is wanted. The paper describes and compares two ways of overcoming the difficulty.Design/methodology/approachOne of the methods depends on transferring data from the screen display via the “clipboard”; the other involves transfer of data into e‐mail messages.FindingsThe “clipboard” method is the simpler and more intuitive of the two and was used by the author to produce graphs, but the e‐mail method could be advantageous where larger amounts of data have to be transferred.Practical implicationsBoth of the methods are extremely tedious in use, and where data has to be transferred repeatedly, for instance in studies where repeated inspection of results in graphical form is needed, the solution would almost certainly be to choose a programming language other than Javascript.Originality/valueThe paper discusses what is believed to be a novel method of transfer of data using e‐mail.
An introduction to alysidal algebra (III)
Authors: Nescolarde‐Selva J. , Usó‐Doménech J.L. 
Published: March 2013

PurposeDeontical impure systems are systems whose object set is formed by an s‐impure set, whose elements are perceptuales significances (relative beings) of material and/or energetic objects (absolute beings) and whose relational set is freeways of relations, formed by sheaves of relations going in two‐way directions and at least one of its relations has deontical properties such as permission, prohibition, obligation and faculty.Design/methodology/approachThe paper looks at the mathematical and logical development of human society structure.FindingsExistence of relations with positive imperative modality (obligation) would constitute the skeleton of the system. Negative imperative modality (prohibition) would be the immunological system of protection of the system. Modality permission the muscular system, that gives the necessary flexibility to the system, in as much to the modality faculty its neurocerebral system, because it allows him to make decisions. Transactions of energy, money, merchandise, population, etc. would be the equivalent one to the sanguineous system. These economic transactions and inferential relations, depend, as well, of the existence of a legislative body with their obligations, prohibitions and permissions that regulate them. A Social System Σ may be considered like an alysidal set with an only alysidal element. The authors consider two theories: Enlarged theory and Reduced theory.Originality/valueThis paper is a continuation of two previous papers – Part I published in Kybernetes, Vol. 41 No. 1/2 and Part II published in Vol. 41 No. 5/6 – and develops the theory of deontical impure systems.
A new method for mining area ecological environment assessment based on credibility measure
Authors: Chen Jiqiang , Ma Litao , Zhang Hong 
Published: March 2013

PurposeThe purpose of this paper is to present a more objective evaluation method for a mining area ecological environment. It proposes the weight of indices with respect to the total goal, and provides a new evaluation method which generalizes the weighted‐average method.Design/methodology/approachFirst, the authors describe the evaluation grades by fuzzy variables in credibility space, and the degree of an index belonging to a grade is transformed to be the credibility measure of a fuzzy event by the credibility inversion theorem. Second, a new algorithm which generalizes the weighted‐average method is proposed to realize the transformation from the credibility degree of the underlying indices to the credibility degree of the total target.FindingsThe method proposed in this paper can obtain the correct results illustrated with a numerical evaluation example. The comparison with two other methods shows that the proposed method has stronger classification ability.Originality/valueThe new method presented in this paper generalizes the weighted‐average method, and provides methods for other evaluation systems with a hierarchical structure.
A two‐layer scheme for membership and classification querying
Authors: Ma Heng , Cheng Hung‐Yu 
Published: March 2013

PurposeThe purpose of this paper is to effectively deal with querying of classification with membership.Design/methodology/approachThe authors propose a scheme comprising a layer of Bloom filter for membership checking and a second layer based on neural network for dealing with the classification requirement.FindingsNot only could false positives be dramatically decreased, but also classification could be achieved with the proposed scheme.Research limitations/implicationsThe experimental data were randomly generated instead of real‐world ones.Practical implicationsIt is difficult to implement this scheme in a real‐world environment, such as the internet. Second, the neural network requires time to converge to a satisfactory level.Social implicationsInternet ethic might be compromised by hackers once they find a way around the filtering mechanism.Originality/valueThe neural network was moditified and utilized for the first time to be suitable for our purpose. Second, the two‐layer design shows effectiveness.
The complexity of measuring complexity
Authors: Iván Tarride Mario 
Published: March 2013

PurposeThe purpose of this paper is to present a reflection that can contribute to the discussion of the possibility, or not, of measuring the complexity of any given system.Design/methodology/approachThe reflection takes place considering three aspects: the first one, of an etymological character, with the purpose to specify the semantics of complexity. The second, epistemological, refers to the forms of complexity measuring in different domains. And the third, of an ontological character, refers to the essential in the complexity of reality, which contains to the observer who observes and that is observes himself.FindingsIt is proposed to reserve the word complex to refer to systems that are treated as an undecomposed and irreducible totality and the act of measuring does not take place; while the expression complicated may be used when the act of reduction takes place by measuring the system.Research limitations/implicationsThe statement made claims to be revised, criticized, questioned, confronted … , with the aim to enrich it and accept it, or else to reject it and discard it.Originality/valueThere is some degree of originality, with respect to other works, that deals with the measurement of complexity, but which does not refer to the distinction that it is possible to establish between complexity and complication, with its epistemological implications and in particular with the challenge of its quantification.
Elements of a cybernetic epistemology: complex anticipatory systems
Authors: Nechansky Helmut 
Published: March 2013

PurposeThe purpose of this paper is to analyze the main differences in the cybernetic structures necessary for elementary anticipation, understood as anticipation of the repetition of one known pattern, and complex anticipation, understood as anticipation of the repetition of known sequences of patterns.Design/methodology/approachA functional cybernetic approach is used to develop the necessary additions to an elementary anticipatory system, so that it can provide standards for anticipated sequences containing seven single patterns or “chunks”.FindingsA subsystem for the anticipation of sequences is developed that is able to: identify the beginning of known sequences; search for different known sequences containing that beginning; and decide to use later patterns of such a sequence as standards for anticipated patterns. Deciding to actually use such patterns for anticipation requires an additional subsystem to switch between the feedback pattern recognition and the feedforward anticipation mode.Practical implicationsThe paper shows how complex anticipation can be developed from elementary forms by adding highly parallel structures that apply the same underlying principles; and it emphasizes epistemological demands for the structure and the data organization that have to be fulfilled, so that anticipation of the repetition of sequences becomes possible.Originality/valueThe paper illustrates the complexity of the anticipation of sequences and it provides the base to analyze more complex forms of specifically human thinking.
Complexity and endogeneity in economic modeling
Authors: Alam Choudhury Masudul 
Published: March 2013

PurposeThe concepts of complexity, endogeneity and circular causation – Myrdal's term was cumulative causation – are shown to be interrelated ones in configuring an economic model in the framework of systemic embedding and its empirical application.Design/methodology/approachThe ensuing framework of economic modeling with complexity provides a controllable and predictable overarching worldview. Anomie in the economic universe and its embedded world‐system are analytically rejected. This consequence is due to the epistemic nature of modeling that combines complexity, endogeneity, and circular causation for attaining predictability and controllability, even in the face of complex systemic perturbations. The epistemology of unity of knowledge contrasted with rationalism is treated as the foundational worldview. An illustrative empirical work is given to convey the conceptual model and its applied viability.FindingsBoth the theoretical and empirical results point out how the induced effects of knowledge flows in reference to the epistemology of unity of knowledge continuously improves the complementary relationships of the evolutionary learning fields, and rejects marginalism as being logically non‐sequiter in such epistemic systems.Research limitations/implicationsMore variables and data would increase the explanation of the continuous simulation in the evolutionary learning world‐system model.Practical implicationsMore data would increase the versatility of the empirical exercise.Social implicationsThe study is based on the idea of social and economic interface in extending the scope of economic modeling.Originality/valueThe paper is very original in the area of heterodox economics that questions orthodox economic postulates and presents the complex methodology by circular causation method instead.
Soft‐computing based navigation approach for a bi‐steerable mobile robot
Authors: Azouaoui Ouahiba , Ouadah Noureddine , Mansour Ibrahim , Semani Ali , Aouana Salim , Chabi Djafer 
Published: March 2013

PurposeThe purpose of this paper is to present an implementation of a soft‐computing (SC) based navigation approach on a bi‐steerable mobile robot, Robucar. This approach must provide Robucar with capability to acquire the obstacle avoidance, target localization, decision‐making and action behaviors after learning and adaptation. This approach uses three neural networks (NN) and fuzzy logic (FL) controller to achieve the desired task. The NNs corresponding to the obstacle avoidance and target localization are trained using the back‐propagation algorithm and the last one is based on the reinforcement learning paradigm while the FL controller uses the Mamdani search and match algorithm. Simulation and experimental results are presented, showing the effectiveness of the overall navigation control system.Design/methodology/approachIn this paper, an interesting navigation approach is applied to a car‐like robot, Robucar, with addition of an action behavior to deal with the generation of smooth motions. Indeed, this approach is based on four basic behaviors; three of them are fused under a neural paradigm using Gradient Back‐Propagation (GBP) and reinforcement learning (RL) algorithms and the last behavior uses a FL controller. It uses a set of suggested rules to describe the control policy to achieve the action behavior.FindingsIn the implemented SC‐based navigation, the intelligent behaviors necessary to the navigation are acquired by learning using GBP algorithm and adaptation using FL. The proposed approach provides Robucar with more autonomy, intelligence and real‐time processing capabilities. Indeed, the proposed NNs and FLC are able to remedy problems of analytical approaches, missing or incorrect environment knowledge and uncertainties which can lead to undesirable effects as the rough velocity changes. The simulation and experimental results display the ability of the proposed SC‐based navigation approach to provide Robucar with capability to intelligently navigate in a priori unknown environment, illustrating the robustness and adaptation capabilities of the approach.Research limitations/implicationsThis work can be extended to consider mobile obstacles with a velocity higher than the velocity of the robot.Originality/valueThis paper presents a learning approach to navigating a bi‐steerable mobile robot in an unknown environment using GBP and RL paradigms.
Cybernetics and systems on the web
Authors: Andrew Alex M. 
Published: March 2013

PurposeTopics that have arisen in the CYBCOM list are discussed, including a link to a valuable online collection of papers having a bearing on cybernetics and an intriguing paper examining the suggestion that the universe exists within a program or computer. Exception is taken to a suggestion that neural sense endings should not be seen as transducers, and an example of neural plasticity depending on use of stem cells from teeth is discussed. An important development in computing technology is reported, stemming from use of carbon nanotubes instead of silicon.Design/methodology/approachThe aim is to review developments on the Internet, especially those of general cybernetic interest.FindingsThe CYBCOM list continues to be valuable, though with unfortunate disregard for “wet” neurophysiology.Practical implicationsThe literature collection mentioned will save a great deal of online searching and trips to libraries. The use of stem cells to allow neural repair may prove to have clinical value. The reported development in computer technology is likely to have a very major impact.Originality/valueIt is hoped this is a valuable periodic review.
