Research on System Architecture and Fine-grained Access Control Strategy of Collaborative Development Platform

摘要

With 3D Prototype model as its core, collaborative development platform is a closed loop information system focus on the process lifecycle management of requirements analysis, product design, process design, frock design, manufacturing execution as well as logistics integrated supporting, issues of system architecture, information integration and fine-grained access control strategy of collaborative development platform are key research contents in this paper, firstly, a distributed system architecture of collaborative development platform is introduced to achieve flexibility.integration and interoperability. Then information integration solution between collaborative development platform and other information systems based on web service is defined and investigated, an implementation process between enterprise collaborative development platform and enterprise resource planning(ERP) via ontology and web services is presented to demonstrate the feasibility and validity of the proposed information integration solution. Finally, fuzzy trustworthiness-involved role based access control strategy(FT-RBACS) is proposed for collaborative development platform, its formalization expression and numerical algorithm are developed to implement fine-grained authorization management and access control for collaborative development platform.
