Evaluation Research and Application of Cloud Service Provider Based on Real-Time Data

Abstract

How to choose the right supplier from many cloud service providers has become a research hotspot. Basing on real-time data, we propose a method for evaluating and choosing the supplier of Machine Tool. Firstly, we establish the index evaluation system of Machine Tool’s performance. Secondly, we apply analytic hierarchy process (AHP) and entropy method to determine the weights of performance indexes. We obtain the performance assessment by the weights. Thirdly, taking the cost into consideration, we calculate the comprehensive assessment score. Finally, we take two service suppliers as example, and draw a conclusion that the service capability of supplier 2 is better than that of supplier 1. The assessment method proposed in this paper provides a reference for matching the service provider and the service demander.
