Flight Control System (FCS) is a key component in aircraft. The high reliability of FCS is needed to ensure the safety flight. In order to achieve the high reliability and make the overall mass and volume as small as possible, mission reliability of the multi-redundancy voting structure of FCS is used as the objective function. The types of the elements and the number of redundancies are chosen as...
Many engineering systems are exposed to run in load-varying environment. Load has a significant impact on the deteriorating process of components and system. Distributing the loads optimally among components of a system can reduce the failure probability and prolong the system life. In this paper, an approach to load distribution for multi-state systems under selective maintenance strategy is developed...
Many systems are required to perform a series of missions with finite breaks between any two consecutive missions. In such a case, one of the most widely used maintenance policies is a selective maintenance in which a subset of feasible maintenance actions is chosen to be performed with the aim at achieving the subsequent mission success under limited maintenance resources. Traditional selective maintenance...
Many systems are required to perform a series of missions with finite breaks or limited maintenance resources between successive missions. In such cases, one of the most widely used maintenance policies is a selective maintenance in which a subset of feasible maintenance actions is chosen to satisfy the subsequent mission requirements. Traditional selective maintenance optimization problems reported...
A multi-objective optimization algorithm for solving a mixed-integer programming problem that normally arises in system-reliability design is proposed. Our algorithm uses a genetic algorithm based on Pareto tournament and equivalence sharing, and a population-based constraint handling method. To evaluate the performance of the algorithm, we apply it in a practical reliability optimization problem...
