Enterprise Production Inventory Policy Under Advance Demand Information Updating And Application Research

In recent years,the study of customer's advance demand information sharing and the production-inventory problem is an issue of great concern in academic circles.The sharing of a customer's advance demand information can make the enterprise understand customer needs more clear,develop a more reasonable production plan,thereby increasing production continuity;Besides sharing advance demand information can effectively reduce the inventory holding to achieve cost savings;and help enterprises to transform the mode of production from make-to-stock to make-to-order.Therefore,this article choose advance demand information and production-inventory as the research object,considering the realization of customer demand and the enterprise cost reducing through the different production-inventory strategy under the updating of advance demand information,which has important theoretical significance and application value.The main work of this paper includes:(1)Production-inventory strategy under advance demand information and information value.Customers provide advance demand information to the enterprise,According to the production capacity of enterprises analyzes the situation of meet and stockout,determines enterprise optimal production cycle?production quantity and the safety stock level,studies the value of advance demand information in production inventory system.(2)The mathematical description of advance demand information updating.The customer provide the next cycle of advance demand information to the enterprise,may make some adjustments before product delivery,Through the mathematical description of advance demand information updating to reflect customer adjustment process,and get the finally actual needs of customers.Through the mathematical description of advance demand information updating,the enterprise can properly control the changes of the customer orders.(3)Production-inventory strategy under demand information updating.According to the advance demand information of the enterprises obtained to discuss:when the enterprises obtains all customers' advance demand information before the lead time.the enterprise ascertains he production quantity according to the previous cycle inventory after meet the demand and the number of current advance demand information.As companies can't use the advance demand information in making production decisions,At this time a premature delivery(s,S)strategy can minimize the risk of supply shortage,When need production replenishment the production quantity is the difference between S and the ending inventory.(4)The application of production-inventory strategy in TL company.The introduction of the TL company's current operating data,analysis of the company access to all customers'advance demand information and part customers' advance demand information,The total cost of the corresponding application strategy of the company.Compared with the current stock manufacturing cost proof the feasibility of the strategy.And make a sensitivity analysis of some key parameters,draw relevant conclusions.In this paper,under the background of the customer demand information sharing,combine advance demand information with the production-inventory,considering the advance demand information updating,conform to the actual situation.Through the application in TL company,proving the feasibility of the strategy,providing certain theoretical guidance and reference value when the enterprises use advance demand information to make production-inventory decision.
