Abstract: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 multi-discipline?]view of the problem.Analysis of the system for business automation (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 feasibil- ity of the proposed method and the effectiveness of the software packages.
