Research On Optimization Of Production And Quality Management Business Process For Foundry Enterprises

At present,the external environment requirements on product delivery and quality for foundry enterprises are extremely harsh.However,there is a difficulty for the enterprise's current production process and quality management process to meet “High Efficiency” and “High Quality” demands.Therefore,business process must be optimized deeply to improve production efficiency under the premise of improving casting quality.So far,most research on process optimization is only to production efficiency or strengthen quality control and the researches on taking two aspects into account are very rare.To solve the above problems,production and quality management status is analyzed in this paper.Combined with ECRS process optimization method,4A process optimization steps and based on double chain collaboration model of production and quality(DCC),“Eraser” process optimization method and “DCC-4A-Eraser” optimization model taking production efficiency and quality control into account are proposed.Then,the relevant technologies are integrated effectively to establish technology systems of optimization model.Finally,the optimization model is applied to three typical middle-small size foundry enterprises(private sand casting enterprise,state-owned sand casting enterprise and private precision casting enterprise).The application results show that the model can effectively and synchronously improve production efficiency and strengthen quality control.The main research works are as follows:First of all,the research situation of foundry enterprises' production and quality management business process optimization is analyzed.And the use of information system to production and quality management business process optimization is expounded and the necessity of optimizing foundry enterprises' production and quality management business process.Secondly,foundry enterprises' production and quality management business process are analyzed.The production and quality management business processes of three typical enterprises are analyzed.Combined with ECRS process optimization method,4A process optimization steps and based on the double chain collaboration model of production and quality(DCC),“Eraser” process optimization method and “DCC-4A-Eraser” optimization model taking production efficiency and quality control into account are proposed.Then the implementation scheme of production and quality management business process is put forward.Thirdly,the key technologies of production and quality management business process optimization are integrated,which include business process simulation technology,business process flexible definition technology,business process nodes driven technology,business process nodes constraint technology and business process global monitoring technology.Business process simulation technology and business process global monitoring technology are mainly used for process analysis and assessment,process flexible definition technology is mainly used to technology achievement of business process optimization method,process nodes drive technology are mainly used to improve the process efficiency,process nodes constraint technology is mainly used to strengthen quality control.Finally,the “DCC-4A-Eraser” optimization model of production and quality management business process is applied to three typical foundry enterprises(HX Foundry Co.,Ltd.,GWT Co.,Ltd.,SD Co.,ltd.).The practical application effects show that the model can effectively optimize the production and quality management business process.And not only it can improve the production efficiency,but also it can strengthen quality control.
