Performance of Complex Repairable Systems
نویسنده
چکیده
Operational systems consist of components that deteriorate and eventually fail. Upon failure, components are either repaired or replaced. Cheap and critical components are usually replaced, while expensive and non-critical components are repaired several times before complete replacement. In this research work, repairable systems undergoing imperfect repair are examined. In this type of repair, each component is repaired several times before being replaced and hence its performance is weakened. The main objective of this research work is to assess system’s performance by measuring its availability. Analytical expressions for availability are derived for simple systems, while the performance of complex systems is assessed and analysed using simulation. Key-Words: Repairable, Availability, Simulation, Failure, Repair

Reliability analysis of repairable systems using system dynamics modeling and simulation
Repairable standby system’s study and analysis is an important topic in reliability. Analytical techniques become very complicated and unrealistic especially for modern complex systems. There have been attempts in the literature to evolve more realistic techniques using simulation approach for reliability analysis of systems. This paper proposes a hybrid approach called as Markov system ...
متن کاملBehavioral study of piston manufacturing plant through stochastic models
Piston plays a vital role in almost all types of vehicles. The present study discusses the behavioral study of a piston manufacturing plant. Manufacturing plants are complex repairable systems and therefore, it is difficult to evaluate the performance of a piston manufacturing plant using stochastic models. The stochastic model is an efficient performance evaluator for repairable systems. In...
متن کاملA Hybrid Fire Fly and Differential Evolution Algorithm for Optimization of a Mixed Repairable and Non-Repairable System Reliability Problem
In this paper, a hybrid meta-heuristic approach is proposed to optimize the mathematical model of a system with mixed repairable and non-repairable components. In this system, repairable and non-repairable components are connected in series. Redundant components and preventive maintenance strategies are applied for non-repairable and repairable components, respectively. The problem is formulate...

The aim was determining optimal com...
متن کاملIncorporating Flexibility in the Design of Repairable Systems – Design of Microgrids
The authors have recently proposed a ‘decision-based’ framework to design and maintain repairable systems. In their approach, a multiobjective optimization problem is solved to identify the best design using multiple short and long-term statistical performance metrics. The design solution considers the initial design, the system maintenance throughout the planning horizon, and the protocol to o...
