Specifics of applying mechanisms of public-private partnership when selecting investment projects

The article highlights the issues of selection of public-private partnership (PPP) projects, project ranking and recommended form and implementation scheme. Despite the fact that PPP approach is widely used all over the world, there is no unified classification of its forms, tools, models, types and methodology of adoption. The article lists the key points of selection of PPP projects and constraints, which arise during selection process. Specifics of implementation of different forms of PPP are described under condition of various factors. Prerequisites for the use of one of the form are presented. Several recommendations on project financing are given.

Design and Solution of a Surrogate Model for Portfolio Optimization Based on Project Ranking

Characterizing the preferences of a decision maker in a multicriteria decision is a complex task that becomes even harder if the information available is limited. This paper addresses a particular case of project portfolio selection; in this case, the measures of project impacts are not assumed, and the available information is only projects’ ranking and costs. Usually, resource allocation follows the ranking priorities until they are depleted. This action leads to a feasible solution, but not necessarily to a good portfolio. In this paper, a good portfolio is found by solving a multiobjective problem. To effectively address such dimensionality, the decision maker’s preferences in the form of a fuzzy relational system are incorporated in an ant-colony algorithm. The Region of Interest is approached by solving a surrogate triobjective problem. The results show that the reduction of the dimensionality supports the decision maker in choosing the best portfolio.
