Guiwu Wei, Yi Wende · Systems engineering and electronics · 2007
With respect to the problem of multiple attribute decision-making which the attribute values are given in terms of interval numbers,an interval appraisal method based on the projection is proposed.Then the calculation steps to solve it are given.As the key step,the projection values are calculated for multiple attribute decision making with interval numbers between every alternative and virtual positive ideal solution and virtual negative ideal solution.Then,according to the projection values,the relative membership degree to the virtual positive ideal solution and virtual negative ideal solution is calculated to rank all alternatives.Finally,an example is illustrated.The result shows the approach is simple,effective and easy to calculate.
