Estimating the remaining useful life of a flow distribution system

Résumé

Flow distribution systems (FDS) are widely used in many industrial processes when it is necessary to distribute products in several ways and then to collect them into one or several discharge destinations, such as water supply, heat supply, electricity supply network, etc. The maintenance decisions on a flow distribution system are challenging because the degradation of individual components is independent and not fully detectable. It can lead to inaccurate diagnostic and prognostic results. Industrial systems are often equipped with multiple sensors on each component to collect the efficient information that helps computing the remaining life of the system (RUL). As multiple data are captured, it is a multiple outputs system. This paper proposes an Input-Output Hidden Markov Model (IOHMM) for RUL assessment to maintenance aid decision making of a multi-component flow distribution system. The components are considered independently for the diagnostic and prognostic of their health conditions and thus of the system. The goal of this paper is to find the best path to know the health conditions of the components for supplying the demand to the destination. The study offers an optimal solution in two steps to keep the system alive longer while it can fulfil customer needs. The first step is the independent monitoring of all components to determine the most appropriate supply planning strategy. The second step is to identify all the possible routes where the flow gets through different components for discharging to the destinations. This aims to benefit such as the alternative flow paths or maintenance activities at the system level. The operating conditions are considered as inputs for each of the components independently.
