基于隶属函数的装配协调顺序优化方法

Assembly Coordination Sequence Optimization Based on Membership Function

面向装配现场,充分利用专家的经验和知识,解决集成装配工装和产品的装配协调顺序优化问题,提出一种基于隶属函数的装配协调顺序优化方法。该方法设置7级评价标准,在两两装配协调顺序对比的情况下采用优先关系排序法通过专家给对象打分;计算总分并求出优先选择比,形成模糊优先关系矩阵;最后,采用平均算法求得每条装配协调顺序的隶属度,形成隶属函数,隶属度最大的即为最优的装配协调顺序。并以某型飞机机翼为例进行了验证。

In order to make the best of experts＇ experience and knowledge from assembly process in face of assembly market and to solve assembly coordination sequence optimization question, an assembly coordination sequence optimization based on membership function method is presented. 7 rank evaluation standards are set to mark by the experts that compare random of each two as- sembly coordination sequences. Calculate total score and precedence selection ratio to form precedence matrix of relation. And finally, membership degree of each assembly coordination sequence is calculated by average arithmetic, and the biggest of which is the best assembly coordination sequence. And the method is applied to a certain aircraft wing as an experiment.
