Optimization of the system for ensuring operability of ground transport and technological machines using mobile workshops
Abstract
Mobile workshops play an important role in the condition of increasing the requirements for minimizing the costs of maintaining operability and losses from downtime of ground transport and technological machines. However, in Vietnam, mobile workshops are used in repair enterprises very rarely. Therefore, the development of a mobile workshop for diagnostics, maintenance and repair of ground transport and technological machines optimization of the number of repair shops in Vietnam is an urgent task. This article discusses the issue of designing to ensure the operability of ground transport and technological machines in Vietnam based on the modular principle. The method of optimization of the number of mobile workshops and specialized types of technological equipment by mathematical modeling is presented. The method of mathematical modeling is more effective than other methods, which allows taking into account the complexity of the process of organizing repair work in the field. The criterion for optimizing the number of mobile workshops and specialized modules is to minimize losses from downtime of ground transport and technological machines and mobile workshops. The calculation of the optimal number of repair stations, the number of specialized modules for the maintenance and repair of engines and hydraulic systems was carried out for a fleet of single-bucket excavators in the northern region of Vietnam.
