생산 및 물류 시스템에서의 Bucket Brigade 효과 분석

Abstract

In the environment that a series of processes have to be done in sequence to manufacture a product (or a service), work assignment, which decide how much elemental work should be assigned to manufacturing resources (machines or workers), is a critical decision？]making matter. In general, work assignment pursues the line balancing (LB) strategy that assigns equal work load to each manufacturing resource as much as possible. However, because LB assigns work without considering difference in workers？f working speed and various changeable factors (mechanical failures, quality problems, etc.) in the system, it is difficult to attain the planned balancing efficiency. To cope with this problem, bucket brigade (BB) was proposed as a new work assignment method. BB is an autonomous distributed work assignment method based on the concept of ants？f collaborative work. In this paper, we discuss the applicability of BB in manufacturing and logistics systems and its problems, and analyze the performance of BB in various work environments through simulation.
