27.01.2017 | Prof. Anne Barros | Title: Modelling degradations, condition based maintenance and imperfect tests for Safety Instrumented System (PresentationESRELSeminarRAMS.pdf) Classical analytical models developed to quantify the availability of Safety Instrumented Systems (SIS) are currently based on the assumption of exponential lifetime distributions for all the units they are made of (1). The aim of the present work is to show how some stochastic modeling framework based on renewal processes, virtual age and multiphase Markov processes can be used to generalize existing analytical tools. The main goal is to include other lifetime laws than the exponential one (e.g. Weibull law or lifetime based on discrete state degradation process) and to model the possible effects of tests and condition-based maintenance. The presentation this Friday will focus on a preliminary discussion about Weibull law versus Exponential law. (1) M. Rausand, Reliability of Safety Critical Systems, Wiley, Hoboken, NJ. 2014 |

03.03.2017 | Prof. Antoine Rauzy Yun Zhang | Yun and Antoine will together give a presentation about modelling of a system with AltaRica. A use case of simplied HIPPS is investigated. (rams seminar 03.03.pdf) •The problem is mainly about how to design a maintenance model step by step to help assessing condition monitoring and optimization of maintenance policies given the description of constraints •But it could also be relevant for problems like how to analyze production of the system how to do risk analysis at the system level etc.… |
