B2B Sourcing Platform Design Based On SOA

Due to the changes in customers' demand or suppliers' services, the relevant business processes should be rearranged, however, current B2B sourcing platform is based on different software platform and different standards.In order to adapt to these changes, B2B sourcing platform should only be re-designed, thus it is of great significance to enhance the expansion of B2B sourcing platform, and achieve the integration of legacy systems with B2B sourcing platform.From the Function view of B2B platform, the current B2B sourcing platform provides product information release, product information inquiry, order management and other basic features, but none of the basic functions related to the purchase recommendation, therefore it is of a very realistic significance to enhance B2B sourcing platform recommendation features to convert product information into sourcing solutions in accordance with customer requirementsThis paper introduces service modeling method based on business process analysis to model the involved services of B2B platform, and designs B2B sourcing platform by serializing the services according to the theory of SOAIn order to achieve the sourcing recommendation feature of B2B sourcing platform, this paper presents an improved NSGA-II algorithm for sourcing multi-objective optimization problem, and verifies the feasibility and effectiveness of the algorithm through examples'comparative analysis.
