Metodologia de projetos para confiabilidade de sistemas discretos via simulação

Abstract

This paper presents the development of a methodology to design for reliability of discrete systems by simulation. The work begins from the principle of scarcity of reliability data of the elements of the production line studied and, through the revision of technical literature of the area, presents a manner of combining obtaining market indicators (benchmarking) and using only available information of sales catalogs, such as price and warranty time, it results in a methodology that is applied to an a priori definition of fault and repair distributions of elements of the line. After creating a reliability block-based simulation model, the system was simulated for 10 years and a 86.66% availability was obtained and the components, whose failures most contributed to the system shutdown, were electronic inspection and the electronic valve. With this it was concluded that measures should be applied to these components in order to improve overall system availability.
