OPTIMISATION OF TARGET INDICATORS OF THE PROJECT PORTFOLIO FOR TRANSPORT AND LOGISTICS SUPPORT OF TOURIST CENTRES

Abstract

The subject of the study is modelling the optimal target indicators of the portfolio of projects for transport and logistics support of tourist centres. The aim of the study is to improve the efficiency of portfolio management processes for the development of transport and logistics support for tourist centres. Tasks: 1) to develop a conceptual model for harmonising targets / parameters of project products for the portfolio of projects for the transport and logistics support of tourist centres; 2) to determine the mathematical description of the main indicators as functions of the parameters of transport and logistics support of tourist centres; 3) to develop a mathematical model for determining optimal and consistent targets for the portfolio of transport and logistics support of tourist centres. Research methods are: methodology and methods of system analysis, methods of operations research. The following results were obtained: the concept of "hierarchy of tourist centres" was introduced, which is a logistics system that is linked to the relevant transport hubs. To manage transport and logistics projects as part of the portfolio, a conceptual and appropriate mathematical model has been developed to determine the optimal and consistent target indicators of the portfolio of transport and logistics projects for tourism centres as part of the hierarchy. The coordination is formed at the level of tourist flows, taking into account their possible distribution among tourist centres, as well as a single source of funding. The model's control parameters are the necessary indicators of the increase in the capacity and quality of service of transport and logistics systems of tourist centres of the same hierarchy. The objective function of the model reflects the maximisation of the economic effect of implementing projects to improve capacity and quality. The constraints take into account funding opportunities, investment efficiency, goals for the development of tourist flows in each centre, and the conditions for coordinating tourist flows in the centres of the same hierarchy (or part of it). The results obtained take into account the peculiarities of forming economic indicators for the hierarchy of tourist centres and form the basis for assessing the value of transport and logistics projects for tourist centres. Conclusions: The results of the study are a conceptual and appropriate mathematical model that allows to form optimal and consistent parameters of the products of projects for the integrated development of transport and logistics support for tourist centres. The model takes into account the peculiarity of the parameters of transport and logistics support, but its structure and construction principle can be used to form models for optimising and coordinating the target indicators of portfolio projects whose products are interdependent.
