Abstract


Production management is the key point during producing cold rolledsteel sheet, the reasonableness, the accuracy and timeliness affectdirectly the order, the continuation of the whole productive organization,the high or low production capacity, the good or bad product quality andthe high or low ability of the enterprises upon tackling the market change.Nowadays, due to the hyper-development of the information technology, itis no longer easy for the traditional artificial management methods tosatisfy the request of the enterprise productive organization. Therefore,the key problem which should be solved in the process of informationalismof enterprises producing cold rolled steel sheet is researching anddeveloping the dynamic management and scheduling system in the processof producing cold rolled steel sheet by using the development results ofmodern information and communication technology.According to mixture of the technological features the traditionalmanagement experiences of producing cold rolled steel sheet and based onthe database technology, information and network technology, this articledesigns and achieves the dynamic management and scheduling system in theprocess of producing cold rolled steel sheet. The system includes thegenerator, optimization of sales plan and production plan, and plan changeof management handling caused by various situations. When designing thesystem, we conclude and make the scheduling rules, and design the materialstructure mould and optimum management mould. By utilizing the materialstructure mould, the technology instruction archive has been establishedand the sales contracts can he merged and preferred to handle accordingto the technology instruction archive and scheduling rules. By utilizingoptimum management mould, the feasible answer of main production plan canbe found, and based on the said answer, by way of optimization managementtheory, try to find the best solving scheme among the said answer and finally achieve the management of the job process plan and variousreal-time rescheduling.The system has been formally operated in the job process and workshopof cold rolled steel sheet, and the application effect is pretty good.It gets through the whole key channel from operation and management toproduction and working, namely, the process from customer contract to jobprocess scheduling, to production tracking and quality tracking, andfinally to the storage of products. It achieves the productionorganization of integrating the supply, production and sales, provideshe powerful guarantee to the continuation, high efficiency of theproduction organization, achieves the whole-process tracking to theproduction logistics, and achieves the accordance of contract number,plan number and steel volume number, solves the difficulty of trackingthe volume number and enhances the production efficiency and productionquality, increases the ratio of good products and ratio of on-timedelivery.
