Abstract:

通过对原始模糊综合评判法的改进,使其能转化为计算机可操作的决策算法以解决飞机复合材料构件的成型工艺决策的问题,并且评判结果更加符合生产实际.将隶属度计算法引入评价矩阵确定环节,实现了计算机代替人力完成评价矩阵的确定,采用为评价范围增加安全裕度的方法规避了原始模糊综合评判法的评价范围划分界限太绝对的问题,利用动态权重分配法和比率标度法相结合的方法实现了计算机自主进行权重分配,并且保证了分配结果切实符合用户实际偏好;以改进模糊综合评判法作为核心算法开发了复合材料构件计算机辅助成型工艺设计系统,并利用该系统进行了实际成型工艺决策,系统决策结果符合实际生产情况,表明了该方法在计算机辅助成型工艺决策应用方面的可行性和准确性.
