DEVELOPMENT OF PLM SYSTEM FOR PRODUCTION PLANNING AND PRODUCTION CONTROL IN SHIPBUILDING

Abstract

Data integration has become an important issue to develop complex products in shipbuilding. This paper introduces a development of a prototype system for PLM systems in shipbuilding. The PLM system is developed for the purpose of precise production planning and the production management in the shop floor. Especially, the PLM system is considered as a use case to provide input data which is necessary for production simulators that reproduce precise work procedures at the shop floor. The data structure in the PLM system is reviewed to provide the necessary data to the production simulator in the beginning of this paper. The data is represented as BOM (Bill of Materials) and BOP (Bill of Process), which are associated with product information, process information, and facility information, and is implemented in the PLM system. The data flow from the PLM system to the production simulator is introduced, then a series of demonstrations from the PLM system to the execution of the production simulator are presented, followed by a discussion of the effects and the future issues of the proposed data structure and the PLM system.
