Increasing the performance of a system by changing reliability

Abstract

The evaluation of the performance of a mechanical system takes into account many factors, including those related to competitiveness, technology and reliability. From the point of view of competitiveness, most companies use the same state-of-the-art information obtained either by applying their own research, development and innovation resources, or by purchasing technologies and patents from other companies or from the free market. Thus the resulting products, if not innovative products, are part of the same range. The global technological level has reached a very high degree of development, using unconventional technologies with high precision, robots, advanced mechanical systems and assembly lines with high productivity as well as verification and control systems on manufacturing flow which makes production to be uniform. Differences between manufacturers begin to appear when the degree of customer satisfaction changes, which is also found in the concept of reliability. Thus, the one who will find the technological solution with the same number of parts, but with a high reliability, will win the market. The paper aims at a detailed study with direct reference to how to increase reliability at the design stage.
