Abstract

Purpose. The focus of the study is development of a technique for forming the optimal sequence of implementation of the investment program of a mining company, which will allow to minimize time for program implementation. Methodology and Approach. The study is based on the network graph representation of technologically interconnected projects of the investment program for the development of new oil and gas fields, formalized representation of project interconnections using an adjacency matrix, reachability matrix and linear programming method providing for the optimal sequence of projects. In the course of the study, four statements were proved, on the basis of which the procedure for the formation of an expanded adjacency matrix was built and the identification on this basis of the system of tasks of forming the optimal sequence of project implementation was made. Results. The authors constructed an economic and mathematical model to minimize the implementation time of the program as a whole, with restrictions on the amount of funding, the continuity of work and their technological sequence, which is based on a network graph. The method for determining the optimal sequence of work is based on identifying the fronts of work, consisting of software work that can be implemented simultaneously. Special attention is paid to the development and justification of the procedure for selecting alternative fronts, the simultaneous implementation of which leads to the interruption of project execution or violation of their technological sequence. A criterion and an algorithm for identifying alternative fronts of work developed by the authors are proposed. The effectiveness of the proposed set of methods is confirmed by the above calculations. Theoretical and Practical implications. The theoretical significance of the work is to justify the procedure for identifying a set of models to form the optimal sequence of implementation of the investment program; the practical significance of the study is to create special methodological support that allows you to create the optimal sequence of implementation of the investment program by the criterion of minimizing the time of its implementation.
