In this paper, an interesting and easy method to solve the multi-dimensional  knapsack problem is presented. Although it belongs to the combinatorial optimization, but the proposed method belongs to the decision making field in mathematics. In order to, initially efficiency values for every item is calculated then items are ranked by using Multiple Criteria Decision Making (MCDA).  Finally, ite...

Multi Criteria Decision Making (MCDM) provides strong decision making in domains where selection of best alternative is highly complex. This survey paper reviews the main streams of consideration in multi criteria decision making theory and practice in detail. The main purpose is to identify various applications and the approaches, and to suggest approaches which are most robustly and effective...

In this study, a survey-based multi-criteria decision-making methodology has been developed for the subcontractor selection problem. The survey is carried out in relevant main business areas under work type of company. These are evaluated according to determined dimensions. For methodology, initially, FUCOM weighting method used calculate relative importance and Then, ranking selecting subcontr...
