A Theory of Hierarchy-Gray for Purchase Decision Support Systems


Article Preview

The selection of suppliers is very important in the purchase of decision support systems. In this paper, firstly the complicated factors of supplier selection which existed in the course of purchase inviting bid are analyzed systemically, Then an comprehensive evaluation index system for picking up the ideal bidders is put forward, Based on the hierarchy-gray theory, a multi-attribute decision mathematics model of purchase inviting bid is constructed, Finally feasibility and effectiveness of the model is testified by a example.
