Uncertain multiple attribute decision making techniques in a cooperative engineering environment

Acquisition requirements for complex weapon systems in a cooperative engineering environment include an analysis of the full life cycle of the total system and an all-round,multi-angle view of the problem. Analysis of the simulation based acquisition(SBA) procedures for virtual acquisition revealed them to be macroscopic,qualitative and inaccurate. A multi-attribute decision making system was therefore developed for the SBA problem space. With this method,the process of solving an SBA problem was reduced to an uncertain and multi-attribute decision-making process. Then according to the degree of uncertainty in the SBA information,the decision making problem was further transformed into an iterative approximation of a numerical calculation. Based on web services,two multiple attribute software packages were developed,one for individual decision-making and the other for group decision-making. Finally,on the SBA cooperative engineering platform,we verified the feasibility of the proposed method and the effectiveness of the software packages.
