REGULATION OF SPARE PARTS REQUIREMENTS FOR DUMP TRUCKS

Аннотация

As is well known, the mining industry serves as a raw material base for the development of major industrial sectors such as metallurgy, mechanical engineering, energy, chemical production, and construction materials. The repair of mining transport equipment is a key factor under harsh operating conditions such as impact loads, vibration, high humidity, dust, and temperature fluctuations, all of which reduce the efficiency of maintenance and repair operations.

Maintaining the operable condition of machinery requires strict adherence to the system of maintenance and repair (hereinafter – M&R). An important role in this process is played by the production and rational use of spare parts, which ensures the reliability of machines and the stable operation of enterprises. The regulation of spare parts consumption is a crucial factor in sustaining equipment performance under strict norms of spare parts use.

The aim of the study is to develop a method for optimizing spare parts requirements for dump trucks, taking into account the risk factor of shortage or surplus. The main research direction is the construction of a mathematical model that considers the cost structure of repairs and identifies the optimal risk value that minimizes financial losses.
