采办协同工程中的不确定多属性决策技术

Uncertain multiple attribute decision making techniques in a cooperative engineering environment

针对复杂武器装备采办协同工程全寿命周期、全系统、全方位的决策需求,在分析了虚拟采办SBA信息具有宏观、定性和不确切特点的基础上,提出将不确定多属性决策引入到SBA问题空间的策略.通过将SBA问题求解过程分解与归纳为不确定多属性决策过程,继而根据SBA信息不确定类别确定解的获取方式,从而将理论上的复杂采办决策问题转化为智能工程化处理的迭代逼近的数值计算,并建立了基于Web服务的多属性个人决策和群体决策2类不确定算法工具包.最后在SBA协同工程平台中检验了该方法的可行性和工具包的有效性.

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.
