Model and Architecture of Open SaaS Industry Service Platform

In order to satisfy enterprises' multiplex requirements for the extensible and programmable operations of information systems, the conception of open SaaS (software-as-a-service) industry service platform, called as OSISP for short, was put forward by combining the open-system design idea and the SaaS technology. The OSISP can meet the extensible, customized and programmable requirements of different enterprises. The operation architecture of an industry service platform was designed, and the abstraction and formalization of operation roles and the model of operation integration were given. Based on the above works, the system architecture of the OSISP, consisting of a basal layer, a platform layer, a system layer, a user layer, a system management layer and a standard layer, was designed in light of the layered architecture design idea. Through the system design, the OSISP on the platform of an automobile supply chain was used so as to improve the exoteric attribute of information systems and enhance the enthusiasm that enterprises participate in the construction and use of the information systems.
