中文摘要
      针对简单直线和U型装配线平衡问题,提出了改进阶位法.依据产品加工的作业元素时间和优先关系,综合考虑作业元素的时间阶位值和位置阶位值,求得综合阶位值.运用改进阶位法对装配线平衡问题求解,得到简单直线、单U型和双U型装配线的生产线平衡结果.结合算例1,对简单直线和U型装配线平衡效果与分枝定界法的结果进行了比较,改进阶位法的结果优于分枝定界法;结合实验算例2,验证了改进阶位法平衡效果好于时间阶位法,因此,改进阶位法是求解装配线平衡问题的有效方法.
英文摘要
      This paper presents a simple and U-shaped assembly line balance problem with the modified ranked positional weight technique. First, according to the processing time and priority relationship of each task, the synthetical ranked positional weight is obtained by taking the time-ranked weight and position-ranked weight into comprehensive consideration. Then the modified ranked positional weight technique is applied to the assembly line balance problem to obtain the balancing results of simple, single U-shaped and double U-shaped assembly lines. With the simple example 1, the comparison of the balance effects is performed in modified ranked positional weight technique and branch-and-bound method. With the experimental example 2, it is proved that the balance effect of modified ranked positional weight technique is better than that of the time-ranked weight technique. Therefore, the modified ranked positional weight technique is an effective method to solve assembly line balance problem.
