Using VPRS-Based Group Decision-Making to Evaluate Partner Relationship in the Value Network of a Mobile Portal

In this paper, we use a group decision-making (GDM) approach based on the variable precision rough set (VPRS) model to evaluate partner relationship in the value network of a mobile portal. We extend the existing study on VPRS-based GDM where the optimal beta_k-stable interval is derived for DM_k [1]. Firstly, in the value network of a mobile portal, VPRS-based GDM is used to evaluate relationship between the mobile portal and its partners. Next, each decision-maker (DM) is assigned a weight, and integrated relationship evaluation (IRE) is obtained. Moreover, on the basis of the IRE similarity between a given mobile portal/partner relationship and the ideal relationship, relationship priority of the partners is obtained. Finally, we give an example and make a conclusion.
