Selection of truck mixer concrete pump using novel MEREC DNMARCOS model

Construction is one of the most developed industries of this century, especially thanks to the high rate of urbanization, mobility, and the tendency to fulfill global goals. A very important component of civil engineering is adequate and modern equipment which depends on the efficiency of execution of operations and processes in construction. A novel MCDM (multi-criteria decision-making) scheme was proposed in this paper, which means the development of the original and innovative DNMARCOS (Double normalized measurement alternatives and ranking according to the compromise Solution) for choosing a construction equipment among 16 variant solutions. For determination the criteria weights, an objective MEREC was applied, whose integration with the DNMARCOS method represents an additional contribution. The obtained results show that the first three alternatives Magnum MK 24.4Z-80/115 RH (A1); Magnum MK 28L-5-80/115 RH (A2); Magnum MK 25 H80 RH (A3) are the best solution for a construction company. To check the robustness of the proposed DNMARCOS method, a comparative analysis was made with the extant MCDM methods, and SCC (Spearman's correlation coefficient) coefficient and WS (Wojciech Salabun) coefficients were calculated. The final results show the justification for the development of the original and innovative DNMARCOS model.
