Fuzzy Relational Degree Analysis Method for Fuzzy MCDM with Time Series
时序模糊多指标决策的模糊关联分析法

The problem of fuzzy multiple criteria decision making (FMCDM) with time series is proposed, and based on fuzzy relational degree analysis, a new decision making method is presented in this paper. The theory of fuzzy set is used to construct weighted suitability decision matrix for every period. The positive and negative ideal solution of each period are then obtained by using a method of ranking of fuzzy numbers. The fuzzy weighted values of the relative fuzzy relational degrees of every alternatives versus various positive ideal solution of different period are calculated and ranked to determine the best alternative. Finally, an example is provided to illustrate the proposed method.
