Applying Possibility Degree Method for Ranking Interval Numbers to Partnership Selection

A new interval number ranking approach is applied for assessment of priorities of the alternative partners,where the attribute values are given out as interval numbers while the weight of each criterion is still exact numerical value pattern.After aggregating with the weighted arithmetic averaging operator,the result is still in the form of interval number.To achieve the priorities of alternative partners we take the possibility method for ranking interval numbers into account which could derive priorities from inconsistent attribute values,thus eliminating the adjustment to the inconsistent attribute values.Moreover,this method is very simple and needs less calculation.An illustrative example is given out to demonstrate this smart method.
