Abstract:
In the current economic scenario, companies are looking to become more competitive, reducing operating costs and unplanned downtime. The biggest challenge for people who are involved in maintenance in today's industries is not just knowing the techniques used in maintenance but deciding which ones are really important for a better asset life cycle. The maintenance stops of large industrial units are periodic events and aim at the reconditioning of equipment, systems and facilities, at an adequate level of reliability, so that production is guaranteed without problems during the next operational campaign. The objective of this work is to create a "live" model that allows to optimize the intervals between stops, from simulations for a certain time of operation to different scenarios of improvement, changes of strategies and extensions, through quantitative methodologies of reliability engineering leading taking into account the cost, risk and performance.
