Application of Improved Interval Numbers TOPSIS Method Based on Mahalanobis Distance in the Evaluation of SME Public Service Platform

摘要

SME public service platform is an economic organization providing a wide range of common services for small and medium-sized enterprise group. It is designed to help SMEs to transform the development mode, to realize the optimal allocation of resources, and to reduce their survival and development cost. This paper aims at the evaluation issue of SME public service platform. 21 specific evaluation indexes of two levels and seven aspects are put forward. The interval number TOPSIS method based on Mahalanobis distance recommended. The use of interval value makes the assignment of qualitative indexes more reasonable. The replacement for Mahalanobis distance eliminates the influence of the linear correlation between the attributes when using Euclidean distance. Finally, an example is used to test that this new method is more scientific and reasonable.
