Study On The Decision Of Product Mix Based On Production Logistics Balance

Multiple-product, medium and small batch production has been the mainstream production mode. Product mix is an unavoidable important question to multiple-product enterprises. The result of PMD have a direct impact on the enterprises product strategy adjustment, resource capacity design, capacity adjustments, investment analysis, production scheduling optimization.This paper points out primarily the flaws exist in the following three aspects related to the present research of product mix : the processing logic, the cost accounting theory and decision making. On that basis, this paper proposes a logical model that based on the balanced portfolio of production logistics and describes the advantages ,features and the solution steps of the model. Based on the product mix logic model for guidance, the paper researches the product mix model based on production logistics balance, focusing on modeling of the portfolio of total amount products in medium and long term as well as the portfolio of products in short term, and the time linking problem of different plan period is analyzed. Then, according to production logistics balance concrete realization, the method of production logistics balance is developed , and the three key technologies of the model - buffer setup, batch determine and lead time problems are researched in depth .While in the practical implementation, this paper seeks to make master production scheduling, material requirement planning and production work planning into one comprehensive scheduling, trying to find a package measure to complete all the plans in different levels. According to balance the production logistics, reduce or avoid conflicts of the capacity of the production system and shorten the production cycle of each product, the whole production system gets optimized and thus a best product mix scheduling is obtained, which directs the settlement of the corresponding control problem in production level and makes sure that the plans in all level can be finished in schedule, and maximize the corporation's profits finally.Finally, the paper makes a empirical research on the production mix of Taicang green town packing Co.LTD. Detailing the solution process of product mix based on production logistics balance is given, and this paper analyzes and solves the problem of the production process control in order to ensure the implementation of production logistics for multiple-product production. Compared the result deriving from the solution process with the present product mix of the enterprises, the paper proves that enterprises can get more profits and can be more conducive to all levels of implementation of the plan for product mix based on production logistics balance.
