Research Based on the Division of Functional Requirements of SAAS

This essay first briefly introduced the concept of the software as a service, as well as the concept of its function configuration, and thus has elaborated that based on the software as a service after acquiring the customer´s functional requirements, functional requirements configuration can be subdivided and each function deployment program can be represented with AND/OR tree. By means of heuristic state space exploration strategy, optimal scheme could be attained after the appropriate evaluation factors and weights drawn up by software customers and software designers of SAAS. At the end of this article, there is a concrete example which inllustrates it is practicable that SAAS software customer requirements can be converted into functional configuration program and by way of heuristic search strategies to get the optimal solution.
