Abstract:
In order to solve the group decision making problems with ordinal interval preference information, a new
decision method is proposed based on VIKOR method. The VIKOR method of compromise ranking determines a compromise
solution, providing a maximum â€œgroup utilityâ€ for the â€œmajorityâ€ and a minimum of an â€œindividual regretâ€ for the
â€œopponentâ€, which is an effective tool in multi-attribute decision making. By integrating the operational laws of ordinal
interval and the concept of VIKOR method, the detail calculation steps are developed for the group decision making with
ordinal interval preference information. Because the comprehensive evaluation values are still interval numbers, we
induce the possibility degree to compare these interval numbers. Finally, an example is given, the result shows the approach
is simple, effective and easy to calculate.
