| Popis: | VIKOR is well-known method that widely used for overall ranking of the alternatives. In this paper an overview of VIKOR method’s algorithm is given. Its analysis is demonstrated that VIKOR method has a few problems such as: it is necessary to set a value for additional coefficient; uncertainty its result’s interpretation. It is need a substantial processing to solve these problems within VIKOR method. However, the development of his basic idea of comparison alternatives on the two criteria relative to the best point by further comparison of the alternatives with respect to the worst point makes it possible to propose a new method – a three-criteria ranking method that will increase the validity of the results by increasing the completeness of comparison of the alternatives. For this new method, the corresponding dependencies are given, and also a step-by-step description of the calculations. The possibility of practical use of the proposed three-criteria ranking method is shown in two computational examples for which there are given the results obtained using known multicriteria methods in the literature. Comparison of the results of calculations obtained using known and new methods indicates that the use of the proposed method in combination with other methods gives a possibility to raise validity recommendations or to find perspective alternatives, which was not found by other methods. These results allow us to conclude that the use of the developed three-criteria ranking method can be quite promising for multicriteria optimization of complex objects. |
