The Research On Production Decision And Decision Support System Based On Mts/mto Hybrid Mode

With the development of economic globalization and reform and opening up to the outside world,under conditions of market economy,the economic situation is changing rapidly and the competition among enterprises is increasing.In order to survive and develop in the fierce competition, enterprises have to seek breakthrough in R&D, marketing, production and purchase.As the core of enterprise management,production decision especially good decisions can reduce operating costs and improve economic efficiency and market competitiveness effectively.This paper takes production decision as its object, and makes an intensive study on master production schedule optimal decision and production scheduling plan optimal decision base on MTS/MTO hybrid mode, which is used by majority of enterprises comprehensively. Firstly, the paper describes the theory and methods of production decision support, "and analysis the current research and content of MTS/MTO enterprise's production decision.Secondly, makes an intensive study on principles and methods of master production schedule optimal decision and production scheduling plan optimal decision base on MTS/MTO. Divide the period according to the feature of MTS/MTO enterprises, and the set up the 0-1 mixed integer programming production master production schedule model, which is sloved by hybrid encoding Genetic Algorithm. After getting the preliminary master production schedule, the paper does the further optimize by using the Period production batch control model to obtained the expected production volume of products;According to the content and features of mixed enterprise's hybrid scheduling model, derived the design procedure of processing start time and completion time under hybrid scheduling model. Set up a model which takes the optimal allocation of equipment and the minimum completion time as target, and solve the model by using two-level genetic annealing hybrid algorithm. Finally, use the information technology and simulation technology to develop a production decision support system according to the Theory and Methods research, which transfixes the master production schedule optimal decision and production scheduling plan optimal decision base on MTS/MTO.The main contribution of this dissertation is as follow:(1)Analysis the production mode of MTS/MTO enterprise, divides order from Confirmed order to planned orders,Divide the period according to the demand patterns of inventory product.Set up mixed integer programming production master production schedule model. (2)After getting the preliminary master production schedule, the paper does the further optimize by using the Period production batch control model to obtained the expected production volume of products, which not only provides a convenient for the further optimization of the operating plan and reduce the size of solution space,but also meets the MTS/MTO mixed mode characteristics of the inventory production cycle. (3)According to the content and features of mixed enterprise's hybrid scheduling model, derived the design procedure of processing start time and completion time,and uses two-level genetic annealing hybrid algorithm to get the optimal allocation of equipment and the optimization of sequencing products. (4)Combines the production optimization theory and methods of decision-making with Modern information technology, use the technology of ASP.NET and SQL Sever to developed a production decision support system.This research has realistic significance and can be used for reference to enhance the production decision-making levels, increase the economic benefits, and improve competitive strengths of enterprises.
