随机制造系统的性能评价对系统设计优化具有重要意义，但对具有一般到达过程和服务时间的随机制造系统进行精确分析是困难的。研究了具有并行制造单元的柔性流水车间，并将其建模为一个并行网络。并行制造单元和有限的托盘导致的阶段之间的强依赖性，现有的方法不能直接使用在这个问题。因此，提出了近似分析，以估计并行制造单元的柔性流水车间的性能指标的基础上的两个时刻近似的并行输入同步站和聚合过程。数值研究表明，所提出的方法的准确性和效率，通过比较它与实验的模拟结果。该工作可为分析和设计更复杂的制造系统提供基础。
Performance evaluation for stochastic manufacturing systems is significant for system design optimization, but it is difficult to exactly analyse these systems with general arrival processes and service times. This paper studies a flexible flow shop with parallel manufacturing cells and models it as a queueing network. Parallel manufacturing cells and finite pallets lead to strong dependence among stages, and existing methods cannot be directly employed in this problem. Thus, approximate analysis is proposed to estimate performance measures of the flexible flow shop with parallel manufacturing cells based on two-moment approximations for a parallel-input synchronization station and an aggregation procedure. Numerical studies show the accuracy and the efficiency of the proposed method by comparing it with simulation results of experiments. This work can provide a basis to analyse and design more complex manufacturing systems.
