The fourth chapter brings forth the designs of the overall scheme , operation procedure of ob and ib documentation and staff assignment for one single documentation center : japanese documentation center . then completes the cost analysis and probes into the concrete implementation process , including the training plan 在构架全球单证中心的基础上，第四章提出了单个单证中心? ?日本单证中心的总体方案设计、进出口单证操作流程设计、人员配备情况设想，并进行了成本分析，并且对具体的方案实施步骤(包括培训计划)进行了探讨。
We can ration analyze and estimate hardware configure chosen in design such as machine tool , the capacity of buffer , the route of transport system etc , and personnel deployment of product line . we can forecast the produce cycle of product , analyze and forecast produce capacity of work - flow , simulate all kinds of predictable or random malfunction , finding bottleneck of system etc . we can also forecast the capability of work - flow under different scheduling strategy 通过对流水线的仿真，我们可以对各种设计方案进行评估，可以定量分析与评价设计中所确定的硬件配置(如机床、缓冲库容量、运输系统路径等)及生产线人员配备情况，预测产品生产周期，分析与预测生产线的生产能力，模拟各种可预见的或随机的故障，发现系统瓶颈等。
