The study has improved the models of making decisions while managing portfolios of projects for reconstructing municipal water supply systems. We have devised a functional model of the general decision-making process for managing portfolios of projects. The model fixes the main stages of the process, information flows, and the employed tools. We have suggested a mathematical model of a multi-criteria value-oriented project ranking that is based on the ENQUIRY method of verbal analysis of decisions. The formulated criteria system allows ranking of multiple projects on the basis of the ENQUIRY method. Thedevised information support of decision-facilitation systems consists in experts’ knowledge and their assessments in the form of paired criteria comparison scales and a developed single ordinal scale.
The suggested model was used in the decision-facilitation system for managing portfolios of reconstruction projects for municipal water systems. The model implementation has confirmed the possibility of ranking a considerable multitude of projects on the basis of a preliminary survey of experts and formalization of the obtained knowledge. It also boosts performance indices of rapid assessment of multiple projects according to several criteria, including qualitative parameters and value characteristics. Application of the devised models considerably reduces the time for decision making and drastically increases the effectiveness of managing the portfolios of projects for reconstructing municipal water supply systems.
