基于约束理论的船舶管系加工进度计划系统研究

摘要

船舶管系生产是船舶建造的一个重要部分,管系生产的进度情况直接影响着全船的建造计划.该研究结合管加工工厂生产管理中的实际问题,通过引入约束管理理论(TOC),开发了适用于船舶管系生产的进度计划系统.该系统集成了管子制品模型、生产资源模型、生产作业模型以及加工数据库,实现了作业计划和生产进度计划编制的自动化.此外,该文评价了系统在应用中所取得的效果,认为系统在管子生产的进度管理、设备利用率和库存等方面均具有较传统方法更优的表现.%The manufacture of ship piping system is one of the major production activities in shipbuilding. The schedule of pipe production has an important impact on the master schedule of shipbuilding. In this research,the TOC concept is introduced to solve the scheduling problems of piping factory, and an intelligent scheduling system is developed. The system, in which a product model, an operation model, a factory model and a knowledge database of piping production are integrated, can make the process planning and production scheduling automatically. In this paper, the details of above points are discussed. Moreover, an application of the system in a piping factory, which achieves a higher level of performance as measured by tardiness, lead time and inventory, is demonstrated at the end of the paper.
