Research On Key Technologies Of CIMS In Moden Shipbuilding Enterprise

Information technology has played an important role in the transformation of shipbuilding from traditional mode to modern mode.Comprehensive digitalization,comprehensive modularization and network platform has been developed as technical support to construct CIMS for shipbuilding,and this is a new challenge for ship manufacturing enterprise.As the background of realization of integrated data management of CIMS in ship manufacturing enterprise,based on the research subject in 863 plan and an application project in enterprise,the CIMS structure and the thought of information reform has been proposed,according to the requirement of information reform,the analysis of current ship-building capability and future demand in Dalian shipbuilding industry corporation (DSIC).The weak link of CIMS in DSIC such as production planning management system, quality management system and logistic information system has been deeply researched.The main content is as follows:With regard to the characters of production processes and the principle of classification management,five-level production plan in company and three-level production plan in subsidiary coorporation have been put forward.Based on the research of Lean Shipbuilding and pull plan system,the RCPSP aided generation system of shipbuilding production plan in order to reduce product production cycle and minimize production cost and improve machining efficiency.After analysizing the characters of quality information of shipbuilding,the technology of quality management and control has been researched and the dada warehouse has been constructed to solve the problems in quality data acquisition,control,examination and evaluation of quality management system.Based on the comprehensive evaluation index system,AHP method has been used to evaluate the quality management system,to realize cooperative operation in quality management and scientific analysis of quality data,and to ensure the steadily improve of quality management system.Considering the complexity and uncertainty in production processes of shipbuilding,an model of components kitting analysis and adjustment has been built up to report the dynamic monitoring results and real-time parts shortness on components assembling,and to guarantee the balanced and ordered production status.In addition,according to the difference of material monitoring requirement of shipbuilding,the multi-layer material monitoring pattern has been founded for lacking parts problem.This algorithm provides techniques guarantee to reduce the production cycle.Combining with production management situation in DSIC,the implementation and application effect has been introduced.
