“…From (Table 1), we make some interesting observations: When A=0, the results are the same as the maintenance model [15], the model in this paper degenerates to the 1. model in their paper. As A increases, C 0 and C * increase, but the percentage of cost reduction decreases.…”

Background:With the progress of technology and people's awareness of environmental protection, more and more used equipment flows into the market. But the lessee is most concerned about the functionality and reliability of the equipment, because fault downtime and repair will lead to the loss of production. Objective:In order to solve this problem, we propose a maintenance scheme for the used equipment using fixed failure rate reduction method. Method:An efficient enumeration algorithm is given to derive the optimal PM policy. Results:In case study, the proposed policy is compared with the performance of other approach through examples. Conclusions:Numerical examples illustrate that the proposed maintenance strategy is practical and it can provide effective decision support for leasing company.

“…Under our approach, the PM actions are performed sequentially with a fixed maintenance degree. As we will see later on, the performance of the proposed maintenance scheme is better than Yeh's scheme [14], and when the initial duration value is zero, the model is the same as the maintenance model [15].…”

“…In one category, parameters are used to describe imperfect degree from various reliability indexes. For example, the improvement factor method 3,4 is in terms of failure rate, the virtual age method 5,6 is in terms of lifetime. These methods have the advantages of modeling imperfect degree intuitively and simplifying the process.…”

Servicing is applied periodically in practice with the aim of restoring the system state and prolonging the lifetime. It is generally seen as an imperfect maintenance action which has a chief influence on the maintenance strategy. In order to model the maintenance effect of servicing, this study analyzes the deterioration characteristics of system under scheduled servicing. And then the deterioration model is established from the failure mechanism by compound Poisson process. On the basis of the system damage value and failure mechanism, the failure rate refresh factor is proposed to describe the maintenance effect of servicing. A maintenance strategy is developed which combines the benefits of scheduled servicing and preventive maintenance. Then the optimization model is given to determine the optimal servicing period and preventive maintenance time, with an objective to minimize the system expected life-cycle cost per unit time and a constraint on system survival probability for the duration of mission time. Subject to mission time, it can control the ability of accomplishing the mission at any time so as to ensure the high dependability. An example of water pump rotor relating to scheduled servicing is introduced to illustrate the failure rate refresh factor and the proposed maintenance strategy. Compared with traditional methods, the numerical results show that the failure rate refresh factor can describe the maintenance effect of servicing more intuitively and objectively. It also demonstrates that this maintenance strategy can prolong the lifetime, reduce the total lifetime maintenance cost and guarantee the dependability of system. ª 2014 Production and hosting by Elsevier Ltd. on behalf of CSAA & BUAA.

“…For the manufacturer, the warranty cost must be minimum in the warranty period will promote the competitive of the market (Glickman and Berger, 1976;Nguyen and Murthy, 1984;Jhang, 2005). Using Failure Rate with Fixed Reduction finds out the optimal maintenance policy for rent equipment (Chan and Shaw, 1993;Yeh et al, 2009). However, the equipment will not be suspended after the warranty period ended in pragmatic way.…”

In this study, we define the time interval ) , 0 [ w as warranty period and the time intervalas the outside of warranty period. The manufacturers provide the customer with preventive maintenance as well as repair policy for free when the equipment was used in the warranty period; consumers need to pay for the same degree of preventive maintenance when the equipment was used in the outside of warranty period. In this research, the method of preventive maintenance is the fixed failure rate reduction. After each implementation of preventive maintenance which reduced the failure rate, there is the level of imperfect preventive maintenance of limited proportion. The proportion of maintenance was divided into a fixed maintenance proportion. We obtained the optimal number of maintenance, the optimal proportion of maintenance degree, the cost of preventive maintenance for fixed maintenance proportion model. We also used the decision-making model to find the optimal number of preventive maintenance, the preventive maintenance cost for fixed maintenance proportion model, when the equipment is used in the outside of the warranty period. In the final, numerical and sensitivity analysis verify the results.
