在Jobshop生产设施的制造车间，共享资源的工作之间的冲突每天都会发生。这使得制造车间的管理变得相当困难。为了解决这一问题，我们提出了一个使用多PERT来计划和管理进度的系统。我们称该系统为并发调度方法(CSM)。在CSM下，每个订单的作业结构在设计阶段被明确，以确定生产过程。结果在类似于PERT图的CSM流程图中详细说明。对这些多路作业结构进行监控，以便跟踪进度，并计划和管理所有订单的时间表。通过这种方式规划的计划能够使资源利用率最大化，并清楚地识别关键路径。关于关键路径的信息有助于解决负载问题。通过这种方式，现场的生产工艺得到了优化，以保持交付日期。此外，由于新订单、交货日期更改请求或进度更改而导致的状态更改可以快速响应。
Conflicts between jobs for shared resources happen daily on the manufacturing floor of a jobshop production facility. This makes the management of a manufacturing floor rather difficult. In order to solve this problem, we are proposing a system to plan and manage scheduling through the use of multi-PERT. We call this system the Concurrent Scheduling Method (CSM). Under CSM, the job structure of each individual order is clarified during the design stage to determine the production process. The result is detailed in CSM process charts similar to PERT diagrams. These multiplexed job structures are monitored in order to follow the progress and the schedule for all orders is planned and managed. A schedule planned in this way is able to have the resource utilization maximized fully and the critical path identified clearly. The information regarding the critical path helps to solve the load problem. In this way, the production process of the site is optimized for keeping the delivery date. Also, status changes caused by new orders, delivery date change requests or progress changes can be responded to quickly.
