Abstract: The optimal activation order (OAO) is introduced as a new concept in reliability optimization problems (ROPs), which sharply contrasts with the conventional redundancy strategies. ROPs commonly comprise one of the four active, standby, Mixed, or K-Mixed redundancy strategies with varying numbers of active components and different times of activation for standby parts. The novel concept of OAO, in contrast, introduces the activation order/sequence of components as a trait with great flexibility that enables system designers to improve system reliability without having to manipulate system structure. The efficiency of this new concept is evaluated through its application to both a specific subsystem with five warm-standby components and a famous benchmark test problem. Results indicate the superiority of the proposed optimal activation order over all previous rival strategies.
