In this paper, we propose a simulation method based on backward simulation and process-oriented simulation to take into account the characteristics of shipbuilding production, which is an order-based industry with a job shop production environment. The shipyard production planning process was investigated to analyze the detailed process, variables and constraints of mid-term production planning. Backward and process-centric simulation methods were applied to the mid-term production planning process and an improved planning process, which considers the shipbuilding characteristics, was proposed. Based on the problem defined by applying backward process-centric simulation, a system which can conduct Discrete Event Simulation (DES) was developed. The developed mid-term planning system can be linked with the existing shipyard Advanced Planning System (APS). Verification of the system was performed with the actual shipyard mid-term production data for the four ships corresponding to a one-year period.

在本文中，我们考虑到造船生产的特点，提出了一种基于向后仿真和面向过程仿真的仿真方法，这是一个具有订单车间生产环境的基于订单的行业。对船厂的生产计划过程进行了调查，以分析中期生产计划的详细过程，变量和约束条件。向后和以过程为中心的模拟方法应用于中期生产计划过程，并提出了一种考虑造船特性的改进计划过程。基于应用后向过程为中心的模拟所定义的问题，开发了可进行离散事件模拟（DES）的系统。开发的中期计划系统可以与现有的船厂高级计划系统（APS）链接。系统的验证是使用与一年期限相对应的四艘船的实际船厂中期生产数据进行的。
