| In recent years,with the upgrade of safety as well as environmental protection laws and regulations in China,the cost of safety and environmental protection of domestic chemical companies is increasing.In addition,the supply side reform leads to the continuous rise of upstream raw material prices,and domestic chemical companies are facing more and more challenges in cost control.Besides that,as one of the top five manufacturing sites in Momentive Performance Materials(MPM)company globally,MPM Nantong site also needs to implement the headquarters strategy of "transforming global operations",and urgently needs to reduce manufacturing cost and improve operations performance.In this paper,the silicone oil production line,which is the largest and most complex production line in MPM Nantong site,is the research object.And silicone oil production line is also very typical in the silicone manufacturing industry.The production management optimization strategy of the silicone oil production line is the research topic,and the lean production theory and tools are used to carry out the research.Firstly,based on current production status of the silicone oil line,the main production management problems of this line are identified,such as the production conversion cost is increasing year by year,the production capacity is tight,the field is disorderly,and the information communication is poor.And then,according to Pareto diagram,fishbone diagram,equipment overall efficiency analysis and other lean production tools,the causes of the problems in the silicone oil production line are analyzed.Then by using the lean production theories such as value stream,5S management and visual management,the optimization strategies of production management of silicone oil line are developed including: utilizing value stream map to optimize the storage and logistics management,improving the overall efficiency of key equipment,implementing 5S management in the field,and executing Gemba board and Gemba walk.These production management optimization strategies are implemented with specific implementation plan as well as supporting actions.After trial operation,it is found that these optimization strategies are effective.As a result,the production conversion cost of silicone oil line is gradually reduced,the overall efficiency of key equipment is significantly improved,the field environment and order are improved,and the feedback on information communication from frontline operators is also improved.The research of this paper has important reference value for similar domestic chemical companies,especially for fine chemical companies,to introduce and implement lean production according to their current needs,to improve the level and performance of production management,and to enhance the competitiveness of the companies.At the same time,the research results and management practices of this paper will be further extended to other production lines of MPM Nantong site and the global peer sites to achieve greater benefits and values. |
