Evaluation of Information System Disaster Recovery Ability based on Experts' Weight and Improved TOPSIS

摘要

Given that current evaluation technique takes no consideration in assignment of experts' weight, we propose a determinate expert weight approach to get different experts' evaluation weight, based on which reasonable significance value is assigned to evaluation index. Then we improve accuracy of expert grading matrix by referring to experts' weight and produce decision matrix. We also establish a disaster recovery ability evaluation model using improved TOPSIS which is upgraded with index weight and positive and negative ideal solution, based on recovery index characters. At last, we demonstrate the feasibility and practicality of the proposed model with experiment statistics.
