Multi-expert constructing Fuzzy cognitive map is a typical multiexpert knowledge combination problem. In this paper, we investigate the use of Dempster-Shafer evidence theory as a tool for multi-expert knowledge combination. In proposed method, we use each expert opinion as a evidence, the possible value of weight as frame of discernment, the expert’s evaluation to a weight on frame of discernm...

In order to overcome the difficulty of cognitive and mining for large-scale multi-relationship system, we take the advantages of intelligent computing of FCM (Fuzzy Cognitive Map) and update the traditional FCM to MRFCM (Multi-Relationship based Fuzzy Cognitive Map) for multi-relationship data mining. The state mining of hyper-node and multi-relationship inference of MRFCM are studied and imple...

The policy objective of safeguarding financial stability has stimulated a wave of research on systemic risk analytics, yet it still faces challenges inmeasurability. This papermodels systemic risk by tapping into expert knowledge of financial supervisors.We decompose systemic risk into a number of interconnected segments, for which the level of vulnerability is measured. The system is modeled i...

This work examines and proposes a new method for web mining inference based on Fuzzy Cognitive Maps. The web mining inference and knowledge extraction consists of two phases. At the first phase the a priori algorithm is used for web mining and a collection of Association rules is inferred. In the second phase, the set of Association Rules is transformed into a Fuzzy Cognitive Map (FCM). It inve...

The employee-employer relationship is an intricate one. In an industry, the employers expect to achieve performances in quality and production in order to earn profit, on the other side employees need good pay and all possible allowances and best advantages than any other industry. Our main objective of this paper is to analyze the relationship between employee and employer in workplace and dis...

ERP tool selection can be seen as one of the most relevant decision-making stages for an organization. This task is conceived as being one of the most difficult ones when an organization is trying to acquire an ERP tool. This work proposes structuring the decision-making selection of ERP tools. With this purpose, we have applied a Fuzzy Cognitive Map based approach capable of offering a definit...

s: Decision making problems always puzzled managers and decision makers in enterprises or organizations. There are many useful soft operation research methods could solve the complicated problem. The paper raises two classic approaches ANP (Analytical network process) and FCM (Fuzzy cognitive map). Those two methods have some similarities and differences. In thus, according to different decisio...

This paper presents a hybrid methodology of automatically constructing fuzzy cognitive map (FCM). The proposed method is based on immune algorithm to learn the connection matrix of FCM. In the algorithm, the DNA coding method is used, and in order to utilize the experts’ knowledge and the feature of system, they are used as “vaccine”. Finally, an illustrative example is provided. The results su...

An approach is presented to multi-expert’s opinions combination based on the Dempster-Shafer evidence theory. In the method, we use multi-expert’s knowledge as evidence, the possible value of weight as frame of discernment, expert’s evaluation to a weight on frame of discernment as basic probability assignment, and use D-S rule combining to give fusion basic probability assignment m. Finally, t...
