Decision-Making Research of Green Purchasing Based on Set-pair Analysis

With the increasing pressure of the environment and the request of building a resource-conservation and friendly society, environmental management has become an important issue which should not be ignored. Governments also put the question of resources and environment on the agenda. Chinese government proposed and formulated a workable green purchasing system in 2005. The foreign study on environmental management has changed from the internal green management and green marketing to green purchasing. Green purchasing is the key factor to breakthrough green technical barriers and to deal with the wave of green consumption. The theory and practice of green purchasing has been concerned gradually. This paper integrates traditional set-pair analysis with markov, and then establishes the dynamic model of set-pair analysis based on Markov chain. From the point of view improving customer satisfaction, the model is applied into green purchasing and shows better results.
