Research On Production Control And Inventory Allocation Policy In Multi-class Customers With ADI

Production and inventory problems are the key issue that the manufacturers have to be confronted with.Effective production control and efficient inventory allocation can accelerate the capital turnover of enterprise,also can improve the profitability of enterprises and customer satisfaction,so as to promote the enterprise image.With the development of information technology,demand information collection has become easy.Advance demand information can be used as the basis for enterprise to forecaste demand,thus we can make dicision quickly and accurately.This paper considers that enterprise is how to determine the production and inventory under the condition of customer orders in advance,using the method of Markov process problem,and discusses the relationship of the optimal control strategy and system state.The main work of this paper includes the following:(1)Analyzing the literatures at home and abroad.Through to research and analyze the literatures of production-inventory problem,we summarize the contributions and deficiency of existing researches,and put forward the production control and inventory allocation problem that based on the advance demand information and multi-class customers.Discussing the manufacturers' production control and inventory allocation problem under the lost sales case and at the same time considering the lost sales and backorders case.(2)Under the advance demand information,we build the model of production and inventory of multi-class customers in the lost sales case.First of all,we process the problem as a Markov process;Secondly,through the unification,the problem is transformed into discrete decision process,and the solution is derived,and got the optimal production strategy and distribution strategy;Finally,the paper analyzes the structure characteristics of control strategy.(3)Under the advance demand information,we build the model of production and inventory of multi-classes customers in the lost sales and the backorder case.Here we consider customer orders as a unit,the problem as solving continuous markov process,and we gained the optimal production strategy and distribution strategy.Finally,we carried on the numerical analysis,and a sensitivity analysis was carried out.The production control and inventory allocation problems that are proposed in this paper based on advance demand information and multi-classes customers are to enrich and complement for the existing researches,and this has a certain theoretical and practical significance,the example analysis of the results provide a certain reference value for the enterprise operation.
