Burn-in and Maintenance Policies

Advances in Applied Probability, 1994
Burn-in is a widely used method to improve quality of products after they have been produced. For a repairable component there are two common types of repair, complete repair and minimal repair. Preventive maintenance policies such as age replacement and block replacement are often employed in field operation.

A general preventive maintenance policy

Optimization, 1976
The paper deals with the optimum preventive maintenance of systems, if two kinds of system failures mag arise. Special cases of the investigated model are the age replacement policy and the minimal repair policy.

“Optimal” Policy in a Maintenance Cost Problem

Operations Research, 1967
This paper is concerned with estimating the “optimal” policy when the (unknown) cost function C(x) is nonlinear with a single minimum, and can be approximated in the neighborhood of the minimum by a polynomial regression. The value x0, at which C(x) attains minimum, is approximated by ◯0 obtained from the regression function, and the expected value of

Maintenance Modeling and Policies

2013
The systems used in production, transportation services, and communication services constitute the majority part of not only industrial activities but also our daily life. Most of them have many units or components with various structure that will degrade with time or usage, and even suffer from a sudden failure due to the random shocks.

Optimal Maintenance Policy for a Fleet of Vehicles

Management Science, 1975
The optimal maintenance and replacement policy for a fleet of vehicles is discussed in this paper that reflects a research effort of three years. The tasks that faced the research team were to list feasible policies, formulate their stochastic behaviour and recommend solution techniques on the strength of the available data.

Optimum Policies for a System with Imperfect Maintenance

IEEE Transactions on Reliability, 1987
This paper considers a system with imperfect maintenance, i.e., after maintenance the system may be either (a) not changed, or (b) failed, with certain probabilities. Formulas for the MTTF and the availability are obtained and the policy to maximize availability is derived. A numerical example applies these results to a triple redundant system.

Replacement Policies with Maintenances

2017
Maintenance actions, such as preventive and corrective maintenances [1], minor and major maintenances [39], routine and non-routine maintenances [40, 41], etc., have been proposed in pairs in literatures.

Maintenance policy designs for PC manufacturers

Proceedings of 2005 IEEE Conference on Control Applications, 2005. CCA 2005., 2005
The cost of field service has significantly increased the need for design for maintainability (DFM). How to decide which maintenance policy should be performed is one of the service cost reduction problems. Exploiting the knowledge-based technology as well as the multi-objective analysis, this paper presents a decision tree selecting model (DTSM) for ...

An inventory control policy for maintenance networks

2004 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS) (IEEE Cat. No.04CH37566), 2005
Many industries rely on maintenance networks to maintain their key assets, and a key characteristic of such maintenance services is the wide use of rotable parts. In view of today's time-based competition, efficiently managing the rotable inventory becomes imperative for a maintenance network to achieve short turn-around-times and low costs.

Maintenance policies with two-dimensional warranty

Reliability Engineering & System Safety, 2002
Abstract A new maintenance policy which minimizes the total expected servicing cost for an item with two-dimensional warranty is proposed. An iterative procedure to estimate the item's failure rate function from historical observations and an optimization algorithm based on Monte Carlo simulation are applied to obtain the best maintenance policy ...
