Research On The Formation Mechanism Of The Dynamic Logistics Alliance Under The Environment Of Supply Chain Management

With the economic globalization and China's accession to the WTO, the competitive environment which enterprises are facing has undergone tremendous changes: the international market competition, the more and more personalized and diverse market demand, the more easily disappeared market opportunities, in order to establish oneself in an unassailable position in the supply chain and to meet the needs of different customers with the fastest speed, the best quality, the lowest cost and the best services, they have to take a new service model which is a organization named dynamic logistics alliance with the other logistics enterprises.However, the theory of dynamic logistics alliance is neither perfect nor systemic currently, so the study of these issues has very important practical significance. With the basis of analyzing the existing literature and theory, under the guidance of the thinking of system engineering, logistics engineering, supply chain management and the dynamic logistics alliance, this paper will mainly study the dynamic logistics alliance from the following aspects:Firstly, explored the relationship between the supply chain management and the dynamic logistics alliance, the relationship among each member of the dynamic logistics alliance, and the position of the members of the dynamic logistics alliance in the supply chain, and the factors which affect the balance of supply and demand in supply chain, and then got the conclusions: the logistics supply and demand imbalance is the main external cause of dynamic logistics alliance formed, the pursuit of economies of scale and scope is not only the main inner cause, but also the result of dynamic logistics alliance formed, and the supply chain partner is the key factor to the success of the dynamic alliance.Secondly, analysed the causes of the dynamic alliance formed and the security to the dynamic alliance, brought up that determining the scale of logistics demand can adjust the balance between supply and demand in the supply chain, applied rough set, artificial neural networks(ANN) and genetic algorithms to establish an advanced model for forecasting the logistics demand, programmed the model with C# which belongs to the computer programming language, and scientifically defined under what circumstance to establish the dynamic logistics alliance; established the indexes and process on selecting the dynamic logistics alliance partner, and applied rough set and Euclidean norm to build the two-stages selecting mathematics model for selecting the partner of dynamic logistics alliance; explored the special role table of economies of scale and scope in the dynamic logistics alliance, applied the mathematics covariance method to build up the model of the economies of scale and scope based on the logistics cost function, and brought up the methods to get the economies of scale and scope.Finally, applied these theories which were established in this paper successfully resolved the future logistics operating issues of Xiongtong Logistics Enterprise Limitid Zhuzhou branch, and also verified that these theories were correct and had a very important practical significance.
