| The hardware printing factory mostly adopts multi-stage production.This production method does not like the flow line having the unified takt and production capacity,involving multiple stages of tempo and production capacity.The manufacture of hardware prints are manufactured by a variety of independent equipment to complete the process of each process section,such as grinding,anode,CNC,screen printing,pad printing,stamping and other processes on different tools and equipment,involving the transfer of products and before and after process,and the production process sequences are different according to the different products.Therefore,the production plan of hardware prints with non-fixed production takt and multi-cross production processes needs to consider the connection between multi-takt and multi-process.This paper selects the W enterprise which mostly produced nameplates as a case to study.W enterprise is a typical multi-stage hardware printing enterprise with many production processes.The production plan of W enterprise only gives the daily scheduling plan,no plan about previous processes,no guiding production plan to guide production,resulting in difficult production tracking,workshops in the accumulation of products,the overall production cycle is long,the sales can not accurately respond to customer shipments,and it is difficult to reach the replied ship date.To study the production plan of multi-stage manufacturing hardware prints,evaluate the feasibility of multi-stage plan implementation,evaluate the multi-stage plan implementation plan,firstly analyze the rules of the connection process before and after the production process,build a multi-stage ordered production model,and then Under the orderly production model,a model of simulated flow production and a combined production capacity will be established,and the multi-stage production plan will be optimized to provide new ideas for such multi-stage production planning enterprises. |
