Hybrid interval uncertain multi-attribute decision making based on set pair analysis

In accordance with the Hybrid multi-attribute decision making problem with attribute value of several interval uncertainty data information, decision making method is presented. First, the paper gives three interval type representations of attribute value, then, makes use of set pair, convert interval type attribute value into the presentation of connection number and construct the connection degree matrix of decision problem, at last, computes the comprehensive connection degree, and sort and choose the projects based on the new definition of risk-priority-degree. The example shows that the method which integrates the certain analysis and the uncertain analysis, reflect the effect of uncertainty on result, is a integral, brief and efficacious uncertainty Multi-attribute Decision Making method.
