Qualification Evaluation in Virtual Organizations Based on Fuzzy Analytic Hierarchy Process

Conventional grid infrastructure implements CA to ensure security and authentication access control which is not flexible, while peer-to-peer applications are flexible enough but no evaluation system to ensure members in a virtual organization are proper and safe enough to corporate with each other. In this paper, we propose an easily extendable evaluation system using the fuzzy analytic hierarchy process (FAHP) to quantify the suitability of request initiators who decide to join a virtual organization for file sharing and transferring. Eleven criteria, derived from literatures review and practical applications, are selected to enrich the whole evaluation framework. We have conducted an extensive experimental study to show the impacts of minor change of each criterion on final qualification values. Simulation results show that FAHP is efficient to evaluate fuzzy integrated factors and the system can be easily applied to different scenarios with minor changes.
