Optimization of public procurement system by using the new mathematical model when selecting the most economically advantageous tender (MEAT)

This Paper analyzes the public procurement system in the Republic of Croatia, regulated by the European Union Directive 2014/24/EU and the Public Procurement Act (OG 120/2016) that lays down two basic criteria for selection of tenders – the lowest price, i.e., the most economically advantageous tender (MEAT). Unlike the lowest price, which can only be applied in exceptional situations and represents a single-criterion decision-making problem with numerous constraints, the MEAT criterion represents a multi-criteria decision-making problem that uses different bid evaluation models. Basic precondition for such models is to define the criteria represented by the MEAT and to determine their relative importance based on the contracting authority's subjective assessment, which also showcases its complexity. Although today there are generally accepted methods of multi-criteria decision-making that offer quality software solutions, the problem of defining the relative preferences of each criterion remains. Accordingly, the main goal of this Study is to present a new model of multi- criteria decision- making in the preparation of public procurement procedures in the Republic of Croatia. Such a model proposes a specific approach that requires decision-makers to be able to rank the importance of selected criteria in descending order, while the mathematical process is based on multi- criteria decision-making in which the value of the weighted criteria is estimated. In the set model, variables represent assigning weight to a criterion, which means that the contracting authority did not have to define them in advance on his/her own, but they had been calculated instead. This is also the basic difference of this model concerning the standard calculation method where relative significance of the criteria must be determined in advance or the weight range for each criterion with the corresponding maximum difference in points must be determined. Since this is a linear programming problem, the calculation will be made by using Excel or its Solver add-in on the selected practical example. Accordingly, it can be assumed that this model might represent a significant contribution to the optimization of public procurement systems both in the Republic of Croatia and in other countries of the European Union.
