Abstract: In industry, the production process requires the non-stop operation of technological equipment because this may be lead to quality degradation of production with economical losses for the company. In this work we examine the quality approach of the reliability and we present a simple framework for identify it. Furthermore, we describe the most useful maintenance policies that can be applied in industrial systems. Also we present the importance and necessity of Management Information System (MIS) that is related with the efficiency of the system. It can be useful in order to take decisions about production, quality of the products, maintenance management and technological equipment. It can even be practical to reliability analysts and manufacturing systems analysts, who wish to model and analyze real manufacturing systems.
