Including the assembly process analysis and improvement of the triangular parts, standard time measured by the stopwatch method based on the improved process routes, the production line design and balance of triangle parts assembly line.

主要研究包括：某部件装配工艺路线的程序分析和改善，采用秒表测时法对改进后的工艺路线进行测定，并制定了标准时间；在此基础上，对某部件装配线进行生产线平衡设计。

Compared with single product assembly line balancing problem, factors which affect multi-variety mixed production lines are more, and it makes more difficult to solve multi-variety mixed assembly line balancing problem.

与单一品种装配线平衡问题相比，影响多品种混装生产线平衡的因素更多，这使得多品种混合装配线平衡问题求解难度加大，而且建立面向不确定条件下的混合装配过程平衡模型难度更大。

Given the complexity of bilateral assembly line and the particularity of the automobile assembly line, we use a heuristic search mechanism of pheromone Combined with the Ranked Positional Weight ( RPW), and the program design method as separate processing module before and after.

鉴于双边装配线的复杂性及汽车装配线的特殊性，本文采用了与位置权重值（RPW）相结合的信息素综合启发式搜索机制以及前后处理模块分开的程序设计方法。
