加工中心是制造行业的关键装备,对其采购方案进行决策需要综合考虑多方面影响因素.为使决策结果更加客观可行,将群组层次分析法与模糊评价法相结合,从精度指标、坐标轴、刀库、运动性能、成本五个方面进行分析.首先在yaahp软件中建立评价体系得到指标权重,然后建立模糊评价矩阵确定指标隶属度及指标分值,其次根据方案得分确定最优方案,最后通过一个实例验证了该方法的可行性.%Machining center is a key equipment in the manufacturing, making its procurement scheme decision need to consider various influence factors comprehensively.Combined group analytic hierarchy process and fuzzy evaluation method to make the decision more objective and feasible, and five aspects including accuracy indexes, axis, tool changer, movement performance and cost were analyzed.Firstly established evaluation system in the yaahp software to get the index weight, then established the fuzzy evaluation matrix to determine the index membership degree and index score, next, chose the optimal solution according to the score, finally the feasibility of this method were validated by an instance.
