Each technical system within itself carries the great potential danger of possible occurrence of failure and damages. Mining machines are characteristic by great investment values, costs of unplanned shutdowns, complex working conditions, and environment and workers hazards. Systematic monitoring of the mining machinery is of great importance for the management of the mining companies. Availability is the overall concept of quality of service. Includes information regard to operating state, an idle state, a standby state and shut down. The availability can be calculated by the time coefficient, which includes mention time state. For time state tracking, specific IT structure is necessary. Such structure is often very expensive and unavailable. An alternative is the expert system, which can absorb partial indicators of the availability, including their uncertainty, diversity, relativity. In this article, an expert’s fuzzy model is presented to analyze and integrate reliability, maintainability, and functionality of three types of bulldozers that operate at the lignite mines. In the end, a comparison of the bulldozers is done. Conclusions can be used for maintenance, in logistics and during the purchasing of new machines.
