Comprehensive Decision Making with Fuzzy Compromised Variable Weights and its Application on Maintenance Order for Entries in Underground Coal Mine

Abstract

Development of fuzzy compromised variable weight vector (VWV) and its application on fuzzy comprehensive decision making (FCDM) are studied specifically in this paper. Based on the definition of variable weight state vector (VWSV), a compromised VWSV is proposed and then further developed to obtain the fuzzy compromised VWSV. According to the algorithm of Hardarmard product, fuzzy compromised VWV is developed. A FCDM model with fuzzy compromised variable weights is developed accordingly. Fuzzy numbers and fuzzy operations are determined by using the fuzzy structured element, which is the essential part for the analytical algorithm of the FCDM model. The developed model was then applied as decision-making method on maintenance order for entries in underground coal mine. The research finding could also provide an alternative way for determination of weights and fuzzy operations in other fuzzy analysis models.
