OPTIMIZATION OF TRANSPORTATION OF INDUSTRIAL EMPLOYEES BY OWN BUSES AND OUTSOURCED TRANSPORT
Optimization problems in the transport industry are very relevant and their solution can be performed quite efficiently by using optimization mathematical methods. Mathematical model is proposed to solve the transport optimization issue. The objective function Fx is defined, the minimum (or maximum) of which corresponds to the achievement of the required state of the system studied. Solutions to the problem aim to minimize the cost of transportation of employees. The mathematical model allows one to calculate the best option for planning and using the fleet of available vehicles, which can be used as a reference. The results of the analysis of mathematical models are better than the solutions based on the “manual” analysis of alternatives. The majority of employees of planning and financial, production and technical departments and other divisions of transport services face similar tasks of search of the optimal solution. The task is set correctly, if there is any list of criteria. As a test platform of optimization, the company “PROTON-PM” has been chosen, looking for improvements in transporting employees from the city center to a remote production site. The article proves that management decisions of complex optimization planning tasks at all levels of management of transport operation and transport processes should be made on the principles of consistency and relevance in accordance with the goals and capabilities of the customer and the service provider. This decision is formed on the basis of a qualitative assessment of the management problem. To form the initial data, two methods of transportation of employees of the enterprise are taken into account: own rolling stock and leased buses from third parties. The routes of transportation and the number of employees to be transported at the same time are determined. The value of the objective function characterizing the minimum costs for such a transportation is calculated. The dependence of costs on a combination of different options for the use of rolling stock of PJSC “PROTON-PM” was obtained. When calculating the maximum cost of 1 km of bus run the existing regulation documents are used.
