Research On Optimization Model Of Material Dispatching System

As an advanced organizes mode and management technology,modern logistics is considered as an important source of profit,except for reduction of material consumption and improvement of productivity. Along with appearance of the importance of logistics,the importance of material dispatching is emerging increasingly,which is the essential part of logistics. Material dispatching is an important problem,which relates to many aspects such as production,consumption,dispatching and so on. On the mean time it is desiderated to optimize. Some discussion is made in this paper on model optimization of material dispatching system.The precondition of material dispatching is that the demand is known,so demands prediction is a very important aspect in material dispatching. Because the influencing factor is multitudinous and difficult to standardize,single forecasting means is seldom successful. On the base of summary of forecasting means,combination forecasting is introduced in this paper. Combination forecasting colligates information of all kinds of forecasting method,so this method avoids losing information in single forecasting model and reduces randomcity,improves the precision of predication.Transportation paradox is the abnormal phenomena in transportation problem,and the reason lies on the definition. As the transportation paradox is concerned,a new transportation model is presented whose restriction is variable. On the basic,a new solution is put forward that can eliminate transportation paradox.According as the fact in a large-scale material dispatching system,a new transportation model is established,which has many characteristics listed below. Firstly,producers' supply capabilities and consumers' demands vary in a certain range. Secondly,relay station have it's own storage. After generalization and simplification,the author discusses its solution.Finally,on the base of analysis of function and structure of the material dispatching system,a general prototype of material dispatching management information system is constructed.
