摘要
The VIKOR method was developed for multi-criteria optimization of complex systems. It determines the compromise ranking list and the compromise solution obtained with the initial (given) weights. This method focuses on ranking and selecting from a set of alternatives in the presence of conflicting criteria. It introduces the multi-criteria ranking index based on the particular measure of "closeness" to the "ideal" solution. The aim of this paper is to extend the VIKOR method for decision making problems with interval number. The extended VIKOR method's ranking is obtained through comparison of interval numbers and for doing the comparisons between intervals, we introduce x as optimism level of decision maker. Finally, a numerical example illustrates and clarifies the main results developed in this paper. (c) 2008 Elsevier Inc. All rights reserved.
