A predictive maintenance strategy based on mean residual life for systems subject to competing failures due to degradation and shocks
نویسندگان
چکیده
In condition-based maintenance area, mean residual life function is recognized as a promising reliability indicator for maintenance decision-making. However, very few maintenance strategies based on the mean residual life have been developed. This paper therefore analyzes a predictive maintenance strategy based on the mean residual life given the degradation level collected periodically in different inspection times. This strategy is developed for systems which are subject to competing and dependent failures due to degradation and traumatic shocks. Numerical examples are given to illustrate the analytical results of the strategy.

Modeling age-based maintenance strategies with minimal repairs for systems subject to competing failure modes due to degradation and shocks
This paper deals with maintenance strategies with minimal repairs for single-unit repairable systems which are subject to competing and dependent failures due to degradation and traumatic shocks. The main aims are to study different approaches for making a minimal repair decision (i.e. time-based or condition-based) which is a possible corrective maintenance action under the occurrence of shock...
متن کاملThe optimal age-based replacement policy for systems subject to shocks
In this article, two different systems subject to shocks occurring based on a non-homogeneous Poisson process (NHPP) are analyzed. Type –I system is consisted of a single unit and type –II system is consisted of two parallel units in which both units operate identically and simultaneously. In type –I system occurrence of a shock causes system stopping and consequently will be received minimal r...
متن کاملAvailability analysis of mechanical systems with condition-based maintenance using semi-Markov and evaluation of optimal condition monitoring interval
Maintenance helps to extend equipment life by improving its condition and avoiding catastrophic failures. Appropriate model or mechanism is, thus, needed to quantify system availability vis-a-vis a given maintenance strategy, which will assist in decision-making for optimal utilization of maintenance resources. This paper deals with semi-Markov process (SMP) modeling for steady state availabili...
متن کاملIntegrated Preventive and Predictive Maintenance Markov Model for Circuit Breakers Equipped With Condition Monitoring
The Circuit Breaker (CB) is one of the most important equipment in power systems. CB must operate reliably to protect power systems as well as to perform tasks such as load disconnection, normal interruption, and fault current interruption. Therefore, the reliable operation of CB can affect the security and stability of power network. In this paper, effects of Condition Monitoring (CM) of CB on...
متن کاملA One-Stage Two-Machine Replacement Strategy Based on the Bayesian Inference Method
In this research, we consider an application of the Bayesian Inferences in machine replacement problem. The application is concerned with the time to replace two machines producing a specific product; each machine doing a special operation on the product when there are manufacturing defects because of failures. A common practice for this kind of problem is to fit a single distribution to the co...
