Abstract

In Article, the problem of modern methods of determination of reliability of the equipment for the purpose of increase of efficiency of functioning of automatic lines at the woodworking enterprises is considered. The influence of equipment reliability on the stability of technological operations is analyzed. Decreased reliability leads to a significant decreased in the valid productivity of automatic lines. Improving the reliability of automatic lines is performed by developing optimal schemes of equipment layout, structural and parametric optimization and reservation. Analysis of the reliability of automatic lines makes it possible to assess the reliability of the production system and its elements, taking into account the strategy of maintenance and repairs, as well as the impact of the external environment. Such tasks are solved using quantitative methods of reliability research. To design automatic lines, different variants of research objects are compared and substantiated. Analyzing the reliability of complex systems take into account the validity of the models, the reality of the results, the adequacy and accuracy of the models, the simplicity and convenience of obtaining results, as well as the scope of tasks to determine quantitative indicators of reliability. The performed researches give the chance to confirm that reliability of the technological equipment considerably influences actual productivity of an automatic line and its efficiency as a whole. A significant increase in the variance of the production interval with a decrease in the reliability of machines in the automatic line causes an intensive decrease in the coefficient of stability and efficiency of the technological line. The coefficient of stability of the equipment decreases with a decrease in its coefficient of readiness. Improving the reliability of automatic lines is carried out by developing optimal schemes of equipment layout, structural and parametric optimization and redundancy.
