基于服务满意度的云制造服务综合信任评价模型
A Comprehensive Trust Evaluation Model for Cloud Manufacturing Service Based on Service Satisfaction
摘要
Abstract
To effectively monitor the trust relationship of inter-enterprises cooperation on service-sharing platform of cloud manufacturing,a model of service comprehensive trust evaluation with comprehensive con-sideration of service satisfaction and its volatility was developed,which was suitable for the operation mode of sharing platform.Firstly,an evaluation index system was designed to quantize service satisfaction by introdu-cing the used time decay function to express the varying trend of service satisfaction with time.Secondly,a computation method of global service satisfaction was put forth using the history informations of service satis-faction of virtual package.Lastly,service comprehensive trust values of virtual resource package was the modi-fication value of global service satisfaction by using volatility value of service satisfaction as the mechanism of rewards and punishments.Computational experiments confirm the used time decay function and mechanism of rewards and punishments are feasible,and they also prove the model is valid to monitor the unstable services provided by enterprises.关键词
