Nuclear Equipment Metalworking Workshop Facility Layout Analysis And Optimization Of Shanghai Heavy Machinery Plant

This paper, taking Shanghai heavy machinery plant nuclear equipment production of metalworking workshop as workshop improvement and optimization of the research object, combining SLP systematic theory of workshop layout, to Shanghai heavy machinery factory metalworking workshop facility layout reasonable improvement. In view of the heavy nuclear equipment in metalworking workshop of handling, storage, loading and unloading process, as a result of the workshop in handling paths cross, transport distance is too long, cause of nuclear facilities, such as personnel reciprocating flow nettled, touch, grinding, injury, brush, thus affecting the quality of nuclear island equipment phenomenon is very serious problem, the following three aspects of research:(1) Metalworking workshop production present situation analysis. Heavy machinery factory of Shanghai metalworking workshop layout situation of each production unit and the basic production situation analysis and introduction, mainly including metalworking workshop equipment layout present situation description, product yield analysis, product analysis, process analysis and so on.(2) Based on SLP Shanghai heavy machinery factory metalworking workshop layout to improve. To Shanghai heavy machinery factory metalworking workshop logistics relationship analysis and determine the relationship between the various types of equipment, in accordance with the process route and processing parts characteristics of workshop production areas, each area according to process characteristics choose different layout methods for equipment planning, combining with the characteristics of process flow and material flow characteristics using the system layout design method to determine position, and on the basis of workshop actual constraints, planning and spatial location of each device map workshop layout. To draw multiple layout scheme, by expert scoring and comprehensive weighted factor analysis method, optimized, the optimal layout scheme.(3) The facility layout improvement plan simulation and comparison analysis. Based on the optimization of Shanghai heavy machinery factory metalworking workshop improvement scheme, with the help of specialized logistics simulation analysis platform e M-plant Siemens plant to improve facilities planning before and after the simulation modeling, after running simulation, simulation analysis result, the output and production status of the time before and after contrast improvement, including the time of waiting, handling, processing), workshop production rhythm, workshop capacity for each station, etc., so as to verify the effectiveness of the proposed scheme.
