摘要

利用petri网直观图形化特点建立装配模型,并根据petri网原理得出可行装配序列。影响可行装配序列的大部分因素是定性的、模糊的、非数值的,将装配序列看作灰色系统,采用灰色聚类决策方法对可行序列进行评估。分析了影响因素的灰色分类并且研究了灰色聚类决策步骤。实例分析表明,该方法为petri网原理所得可行序列进行正确的评估并且得出决策向量。

Abstract

This paper establishes assembly model according to the intuitionistic graphics mode characteristics of petri net, and gets feasible assembly sequence according to the principle of petri net. Most of factors influencing assembly sequence are certainly qualitative, fuzzy, non-numerical, assembly sequence is regarded as a gray system, and grey clustering decision method is adopted to evaluate feasible assembly sequence. This paper analyzes the gray classification of the influence factor and studies grey clustering decision method steps. The analysis of example indicates this method can evaluate correctly the feasible assembly sequences according to the principle of petri net and obtain decision vector.
