Assessment of reliability performance based on truck driver satisfaction survey

A study has been underway since 2022 to improve the performance of dump trucks in the Erdenet open pit mine in Mongolia. In the first year, our research team dynamically determined the fuel consumption of trucks based on the mining-technical conditions. The next objective of the research was to estimate the production performance of trucks in relation to mine depth and the obsolescence of the dump trucks. To achieve this goal, technical reliability analysis was performed using satisfaction surveys from drivers to determine which indicators to highlight and analyse. In labour process analysis, each particular job in any industry is graded by a combined assessment of the level of knowledge and required skill of the person to perform the job and the level of personal experience they can attain from the job. In manufacturing, jobs have their own grading, which provides the basis for wages commensurate with the level of professionalism required to perform the work. Thus, each industry will create a functionally related labour-wage system: job rank, professional degree, and wage rate. When mining companies determine the number of jobs available for a given year, they list the qualifications of the people required to fill each job. This will be the basis for proper planning of wage remuneration, professional development of workers, planned increases in wages, social welfare from profits and the redistribution of income reflected in budgets.
