- Abstract
Abstract: In reliability engineering, load sharing is typically associated with a system in <italic>parallel</italic> configuration. Examples include bridge support structures, electric power supply systems, and multiprocessor computing systems. We consider a reliability maximization problem for a high‐voltage commutation device, wherein the total voltage across the device is shared by the components in <italic>series</italic> configuration. Here, the increase of the number of load‐sharing components <italic>increases component–level reliability</italic> (as the voltage load per component reduces) but may <italic>decrease system–level reliability</italic> (because of the increased number of components in series). We provide the solution for the 2 popular life‐load models: the proportional hazard and the accelerated failure time models with the underlying exponential and Weibull distributions for both a single and dual failure modes.
