multiple-criteria model for optimal off-road vehicle selection for passenger transportation: bwm-copras model

Introduction/purpose: adequate evaluation and choice of off-road vehicles used in performing various types of assignments is a very important factor which affects user mobility and safety as well as the quality and efficiency of carrying out transportation activities in the serbian armed forces (saf). methods: this paper thus proposes the bwm (best worst method) and the copras (compressed proportional assessment) models for the selection of the optimal off-road vehicle for the needs of the saf. the relative weight of the criteria used to assess potential off-road vehicles was established using the bwm method. in addition to the copras method which is a component of the basic decision-making model, in this paper, the mabac (miltiattributive border approximation area comparison) and mairca (multiattributive ideal-real comparative analysis) methods were also applied through result validation. results: by testing the bwm-copras model on the example of optimal off-road vehicle selection in the saf, a high rank correlation was achieved. the results were validated through the statistical processing of the results obtained through the implementation of various multi-criteria techniques by applying the spearman's rank correlation coefficient. conclusion: the results display stability of the results of the proposed model in ranking alternatives and prove the feasibility of the proposed approach to handle multi-criteria decision making problems.
