Application of economical and mathematical methods to manage projects

Abstract

Introduction. The deadline for the planned works in the project is one of the critical parameters that are not mostly approached. In addition, non-compliance with the deadline usually leads to an increase in the cost of the project. It can be the failure in fulfilling another critical parameter of the projects. One of the reasons of this problem is the non-optimal appointment of job executors.

Purpose. The article aims to develop an economics and mathematical model for optimal selection of project executors under uncertainty.

Results. In order to achieve the goal of the work, factors, which influence its scheduled completion, existing models of executors’ optimal selection are analysed. The unsolved parts of the problem are identified. Executors’ selection criteria and significant limitations of the model are analysed. It has been concluded that one of the most critical factors is the uncertainty of the executors’ production capacities at the time of their carrying out (the number of free technics or workers who will be free and may be involved in future work). The proposed model allows choosing the optimal executors not only under the term’s criteria, but also under taking into account the total cost of the planned works. It can also be used by enterprises and organizations that involve a subcontractor to perform certain work.
