摘要

在将任务分配给工作中心时,会出现许多问题,特别是在确定线路平衡所需的工作站数量时,这需要最小的理论工作站数量。最常见的问题是瓶颈。本文提出了一种解决实际需要的工作站数量超过最小理论数量,且浮动任务(工作中心)的标准时间超过周期时间的单模生产线上的浮动任务问题的方法。浮动任务将代表一个关键的瓶颈活动。该方法通过将关键瓶颈和非关键活动的标准时间最小化,使非关键活动空闲时间的平均值最小,从而将生产线效率从(77%)提高到(88%),将平衡延迟从(23%)降低到(12%)。

Proposing a new method to solve line balancing bottleneck problem in the single-model line
Many problems occur when assigning tasks to work centres, especially in determining the required number of workstations for line balancing which requires a minimum theoretical number of workstations. The most common problem is bottleneck. In this paper, a method is proposed to solve floating tasks problem in single-model line when the actual required number of workstations exceeds the minimum theoretical number, and the standard time of the floating task (work center) exceeds the cycle time. The floating task will represent a critical bottleneck activity in line. The proposed method depends on minimizing the standard time of critical bottleneck and non-critical activities by a minimum free-floating time depends on the average of slack times of the non-critical activities, and it will increase the line efficiency from (77%) to (88%), and balance delay is minimized from (23%) to (12%).
