Research On The Key Technologies Of Constructing Virtual Logistic Enterprise Based On Semantic Web Services

Under the background of the economic globalization,networking,information,the whole logistics industry operation environment,operation technology and industry rules have changed greatly:the logistics business department and partners have packed own private business process into Web services with public interface and the model of cooperative.Therefore,how to provide an effective mechanism to build loose logistics enterprise alliance not involving the merger of assets becomes one of urgent problems to be solved now.Virtual Logistics Enterprise(VLE) is a flexible and loose alliance of logistics enterprises.It doesn't involve the merger of assets and is based on the logistics business foundation and network technology.Logistics operation in the form of virtual logistics enterprises is convenient,efficient and low-cost.It is also in line with the required characteristic of the economic globalization,networking,and information for the development of the logistics industries.It is of great significance and values that researching on logistics-oriented network computing and the key technologies about the services framework and operational mechanism.In other words,it is important to build the virtual logistics enterprise model based on the semantic Web services.[1]The paper proposes a virtual logistics enterprise model based on the semantic Web services.Guiding by the business process template sets dynamic defined and logistics tasks, the model discovers the suitable the web services through the vertical and level module, then maps the web service to the corresponding business process templates,finally obtained an optimal virtual logistics enterprise alliance.This virtual logistics enterprise alliance not only well meets the logistics activity of business process and business goals, but also fully embodies dynamic,flexible and intelligent character of the VLE.[2]Research on the logistics domain ontologyWeb Services is the realization foundation of Virtual Logistics Enterprise model based on Semantic Web Services.In order to make Web services distributed on the Internet to more automated,intelligently interact,the paper proposes and builds the logistics domain ontology to resolve the current widespread on the Web problem about heterogeneous information format,semantic multiplicity and the lack of information and non-uniformity.[3]Research on Web services.For the chief enterprises which organized the logistics activities,the choice of the partner companies has changed to the choice of numerous Web services on the Internet, The paper novel introduces the KPI into the definition of semantic Web services. Therefore introducing the KPI into the definition of Web services will make the choice of Web services more accurate and more appropriated for objectives of logistics activities.The paper proposes a KPI access model.It is used to select the KPIs applied into the definition of a semantic Web services.That can ensure that the KPI applied into the definition of Web services is a scientific,standardized and objective which is less affected by the user's personal preferences and ensure that the service module assembly for Web services assembly of the efficiency and accuracy.[4]Research on Web services discovery.In this paper CLIQUE algorithm was improved,and puts forward the Grid translation compensation.This not only effectively resolve the Web service classification problem,but also embody the characteristic of flexible module,namely can find replacements of web services that can not executed for Web service or performance not meet users' requirements.And in order to ensure that the formation of logistics enterprise alliance with convenient,efficient and low cost,and puts forward the characteristics of ant colony algorithm SWSVLEM solution of Web form,which can meet the chain of combination of business chain is formed by the optimal,and ensure the logistics cost of optimal and every Web service cost optimal.
