A new approach based on evidential reasoning is introduced to synthesize linguistic judgment information of experts. Firstly, the basic probability assignment (BPA) of each focal element is calculated by dealing with the incomplete linguistic decision matrix given by different experts. The consistence and adjustment problem for the BPA among experts is analyzed so as to propose the rule of combination...
The health status of Yantai urban water-based system(Yantai UWBS) from 1996 to 2005 is evaluated with fuzzy pattern recognition model based on relative membership degree theory. Firstly, with AHP method, the index system is divided into four hierarchies: object hierarchy, criteria hierarchy, factor hierarchy and index hierarchy. And reference to relative national normative criterions or the index...
Recently, the performance evaluations of raid manufacturing systems (RMSs) has become more and more crucial, because it is the foundation for investment and implementation of RMSs. However, due to various complex and vague factors involved in RMSs, it is hard to evaluate exactly. To measure a RMS roundly and objectively, a multi-level fuzzy comprehensive evaluation approach based on analytic hierarchy...
The development of rockfall has complicated, multifactorial, fuzzy and uncertain characters. Based on analysis of rockfall development factors, the authors quantified the weighting matrix of these factors using AHP model. And then the weighting matrix was introduced into fuzzy integrative evaluation. By combining the AHP method with fuzzy theory, the authors presented the AHP-Fuzzy methd for stability...
Data envelopment analysis (DEA) is a non-parametric method for evaluating the relative efficiency of decision-making units (DMUs) with multiple inputs and multiple outputs. Unascertained math is a useful tool for dealing with unascertained information. The unascertained theory was introduced to data envelopment analysis in this paper. A new model, which is called interval data envelopment analysis...
