The Research On The Efficiency And Optimization Of Supply Chain Network

The supply chain is a dynamic and integrated system, in which all enterprises are integrated to obtain the optimization of the whole chain. Integration is a process of redefining and connecting parts of a whole in order to form a new one. In the traditional integration of supply chain, the definitions of parts were usually limited by the boundary of the enterprises; the integration emphasizes connecting each enterprise with logistics and information communications. This paper proposes a theory of a Virtual Value Net, in which a supply chain as a complicated network system consists of three nets: logistics net, information net and organization net, the supply chain integration is just on how to construct and coordinate these nets and their nodes, so that to provide more business value to the final customers, and be adaptable to business and technology changes.This paper presents a method, by which the supply chain integration solution is designed, improved and evaluated. The method cares more about the business processes of the whole supply chain, in which the organizations' boundaries are regarded as transparent, activities in business processes are selected and organized as business components, logistics flow and information flow are analyzed and optimized according to the integration degrees of business components. The paper utilizes the measure about custom's value and the ability to add the value of nets, establishes the model of constructing logistics net and information net; the paper used some indexes in social network analyses and further establishes the model of constructing logistics net, information net and organization net.The paper uses the method of social network analyses to research the Luen Thai's supply chain city, and finds that Luen Thai achieves the construction and optimization of network with the change of manufacturer to provider of supply chain in apparel industry, and has included the nodes of high centrality in the most degree. In some sense, the Luen Thai's supply chain city realizes the high integration which virtual value net requires, and is one of the best examples about the model of optimizing the nets' attribute in the paper.
