Performance analysis of re-entrant flow shop with single-job and batch machines using mean value analysis
针对回流流水线中单件加工机和批加工机并存的复杂情况，提出一种基于均值分析的近似方法，估算系统平均周期时间和吞吐量，并用仿真验证了方法的有效性。
We propose an approximate method based on the mean value analysis for estimating the average performance of re-entrant flow shop with single-job machines and batch machines. The main focus is on the steady-state averages of the cycle time and the throughput of the system. Characteristics of the re-entrant flow and inclusion of the batch machines complicate the exact analysis of the system. Thus, we propose an approximate analytic method for obtaining the mean waiting time at each buffer of the workstation and a heuristic method to improve the result of the analytic method. We compare the results of the proposed approach with a simulation study using some numerical examples.
