AN OPTIMIZATION OF OPERATIVE AUTOMOBILE VEHICLE FLEET MANAGEMENT AT THE INDUSTRIAL ENTERPRISE

Abstract

The paper proposes the optimization method of operative transport fleet distribution by customer’s demand in the conditions of the industrial enterprises. One of the main problems in the transportation process planning is the effective choice of vehicles, which are appropriate in specific operating conditions. As is known, the technical and economic characteristics of the vehicle are established by the transportation planning process and vehicle operational properties: carrying capacity and its usage degree, road safety, fuel consumption, durability and reliability, ease of use, maintenance, and repair fitness. Cargo transportation process at the industrial plants has its own features, unlike automobile transport firm. An operational activity of industrial enterprise transport department aims to the complete customer demands satisfaction. As customers, in this case, are departments of the industrial enterprise. Whereas own automobile freight fleet is used on transportations with minimal operational expenses as far as possible. Interchangeability of vehicles that have different types for different cargoes delivery and external transport involving in case of deficit ones give the opportunity to reduce of expenses for transportation plan fulfillment. The given task is formulated as discrete linear programming model with constraints in form of inequalities and binary variables. The numeric example is given that solved by MS Excel computer software. The results of investigation can be used for solving tasks of operational and midterm planning of freight automobile transportations at the industrial plants.
