Experienced process plant personnel observe that corrective maintenance work on one asset may often be followed by the same or connected assets within a short amount of time. This problem is referred to as cascading failure. Confirming if these events are chronic difficult given number and volume operation data. If can identified, preventative measures implemented prevent those cascades, elimin...

Abstract: The reliability analysis of load-sharing m-out-of-n systems where the workload is shared by the remaining working units when a unit fails is proposed in the paper. General expressions are provided for the m-out-of-n system reliability by arbitrary probability distributions of time to failure of units. Simplified methods are given for computing the survivor function in cases when the t...

In the design of interlock loops for the signal exchange in machine protection systems, the choice of the hardware architecture impacts on machine safety and availability. The reliable performance of a machine stop (leaving the machine in a safe state) in case of an emergency, is an inherent requirement. The constraints in terms of machine availability on the other hand may differ from one faci...
