- Abstract:
- Aimed at the remanufacturing system, the effect of the uncertainty of returns’ quality on bottleneck shifting is investigated. A novel definition of bottleneck station is presented and the probability of a station becoming a bottleneck is also given. By calculating the effective output, the effective operation time(EOT)and the ratio of EOT of each station, the system’s current bottleneck of effective output time is determined. By calculating the probability coefficient of variation and index of bottleneck shifting, the quantitative performance of bottleneck shifting is obtained. Discrete event simulation and the experiment design method are adopted to simulate the system, in which the proportion of quality grading, repair rates and process routes are considered. The case study shows that the uncertainty of returns’ quality greatly increases the probability of bottleneck shifting, and with the increase of the discrete degree of the returns’ repair rate, the bottleneck shifting phenomenon is more obvious. Furthermore, bottleneck shifting is closely related to the process route of the dominating returns’ quality grade.
- 以再制造系统为对象, 研究回收件质量不确定性对系统瓶颈漂移特性的影响, 提出了瓶颈工位新的定义, 并给出工位成为瓶颈工位的概率算式.通过统计各工位有效产出、有效作业时间以及有效作业时间比例等性能指标, 确定系统当前有效产出时间的瓶颈工位.通过计算瓶颈的概率变异系数和瓶颈漂移指数, 定量描述系统的瓶颈漂移特性.采用离散事件仿真技术和试验设计方法, 研究质量等级比例、修复率以及工艺路线等参数对系统瓶颈漂移特性的影响.案例研究表明:回收件质量的不确定极大地增加了瓶颈漂移的概率;回收件修复率离散程度越高, 瓶颈漂移的现象越明显.此外, 瓶颈漂移特性还与主导等级回收件的工艺路线密切关联.
