Component availability for an age replacement preventive maintenance policy
… is maintained by an age replacement preventive maintenance policy. The availability function, A(t), is a function of time and is defined as the probability that the component functions at time t. The component is considered to have two states: operating and failed. In this policy, the component …

Maintenance Policy Selection Using Fuzzy FMEA and Key Performance Indicators
For decades, maintenance management has been applied in diverse industries to maximize the equipment productivity through maintenance planning, maintenance control, and several improvements regarding to economical features. In maintenance management, Maintenance Policy Selection (MPS) has a key …

Discrete Event Simulation Model for Project Selection Level Pavement Maintenance Policy Analysis
… and effect. Better investment decisions for maintenance will increase the condition of the flexible pavement and will end up with a better level of service. Therefore, better investments decisions on pavement maintenance will increase the economic growth and global competition for the area. …

The Effect of Maintenance Policy on System Maintenance and System Life-Cycle Cost
… (simulation) model that evaluates the effect of maintenance policies on system performance and life-cycle cost. The model highlights factors such as learning, aging and the technological upgrades that occur during the life-cycle of a system. The metrics used to measure the effectiveness of …

Availability Analysis for the Quasi-Renewal Process with an Age-Dependent Preventive Maintenance Policy
… can also be used to model the increasing time of maintenance actions due to the increasing difficulty of maintaining an aging system by setting the parameter to a value larger than 1. We construct a model where the operating times follow a quasi-renewal process and the corrective/preventive …

Estudio de la fiabilidad de sistemas con reparaciones pospuestas
… damage. Also, it is dedicated to study a new maintenance policy for repairable systems, based on the concept of delayed repair.

Reliability Analysis And Optimal Maintenance Planning For Repairable Multi-Component Systems Subject To Dependent Competing Risks
… reliability models and scheduling optimal maintenance plans for multi-component repairable systems, however, is still a big challenge when considering the dependency of component failures. Existing models commonly make prior assumptions, without statistical verification, as to whether …

Stent Reliability and Maintenance: Integrating Probabilistic and Physics-of-Failure Models
… modeling framework to study reliability and maintenance strategies for stent deployment and operation through two dominating failure processes: delayed failures or crack growth due to cyclic stresses and instantaneous failures due to single-event overloads. We develop the reliability model …

Optimal depot level maintenance planning
… planning and management of costly depot- level maintenance for the MiAl is of concern to the Marine Corps. However, there is currently no model or other management tool available to analyze the effects of various maintenance policies. The goal of this thesis is to develop such a model to aid the …

Reliability Trend Analyses With Statistical Confidence Limits Using the Luke Reliability Trend Chart
… of other outside forces such as a change in maintenance policy, escalation of alignment problems, or a change in training program. It is important to know when a system is changing dynamically in order to assess design, policy and program changes and to determine when changes in life cycle …

On The Maintenance Modeling and Optimization of Repairable Systems: Two Different Scenarios
… we study two different scenarios on the maintenance modeling and optimization of repairable systems. First, we study the long-run availability of a traditional repairable system that is subjected to imperfect corrective maintenance. We use Kijima's second virtual age model to describe the …

Maintenance strategies affecting equipment performance
Proper maintenance of plant items is crucial for the safe and profitable operation of process plants, The relevant maintenance policies fall into the following four categories: (i) preventivejopportunistic/breakdown replacement policies, (ii) inspection/inspection-repair-replacernent policies, …

District Level Preventive Maintenance Treatment Selection Tool for Use in Virginia
Preventive maintenance has the potential to improve network condition by retarding future pavement deterioration. The Virginia Department of Transportation uses its pavement management system to determine maintenance targets for each district. The districts then use these recommendations to select …

A Bivariate Renewal Process and Its Applications in Maintenance Policies
… pursue a bivariate approach in reliability and maintenance modeling. This research presents a framework for bivariate modeling of a single-unit system. Five key efforts are identified and organized as: (i) bivariate failure modeling, (ii) bivariate renewal modeling, (iii) bivariate corrective …

Availability analysis of opportunistic age replacement policies
… replacement of the other component. This last maintenance policy is called an opportunistic replacement strategy. The system functions only if the both components of the system are functioning. The system fails if either of the components fails. Component i is replaced if it fails before …
