Repair Replacement Policy Research Articles

Repair replacement policies

In this paper we introduce the concept of repair replacement. Repair replacement is a maintenance policy in which items are preventively maintained when a certain time has elapsed since their last repair. This differs from age replacement where a certain amount of time has elapsed since the last replacement. If the last repair was a complete repair, repair replacement is essentially the same as age replacement. It is in the case of minimal repair that these two policies differ. We make comparison between various types of policies in order to determine when and under which condition one type of policy is better than another.

Repair Replacement Modelling over Finite Time Horizons

In this paper an integral equation approach is given for evaluating the expected cost of repair replacement policies over finite time horizons. An asymptotic estimate of this expected cost is also obtained. The policy involving imperfect repair on failure with replacement after N failures is taken as an illustrative example and optimal policies N* are found for both infinite and finite time horizons of use.

Availability measures for components maintained by repair-replacement policies

A renewal-reward process model is given for a component maintained by a general repair-replacement policy. The point availability of the component at time t and its expected operating time over the interval (0, t ) are defined in terms of a pair of related integral equations. These two equations are then solved numerically to obtain values of the two measures for the policy of repair plus replacement at age τ.

Developing an optimal repair‐replacement strategy for pallets

AbstractA Markovian model is presented for the development of an optimal repair‐replacement policy for the situation requiring a decision only at failure. The problem is characterized by the presence of growth which is integrated into the formulation. The model is applied to an actual problem, with data analysis and results given. Substantial savings are indicated.
