“…The corresponding maintenance time are as follows: T f = 0.02 years, T p = 0.004 years. Besides, set m = 0, 1, 2, 3, 4, 5, and the relevant PM cost is C p (0) = $0, C p (1) = $10, C p (2) = $30, C p (3) = $60, C p (4) = $100 and C p (5) = $160 (Cheng, et al 2015;Wang and Su, 2016).…”

“…Under this policy, the manufacturer should not only provide free repair or replacement upon failures, but also guarantee the availability of the warranted equipment to be over a negotiated level during the warranty period. The existing research on availability-based warranty is quite limited (Cheng, et al 2015;Yan, et al 2011;Iskandar, et al 2014). investigated an availability-based warranty policy in the framework of onedimensional (1D) warranty.…”

Abstract.A two-dimensional (2D) availability-based warranty policy is investigated from the view of the manufacturer. Under the policy, the manufacturer guarantees a negotiated availability for the products during the warranty period. In order to satisfy the availability requirement with rational cost, 2D preventive maintenance (PM) strategy is carried out, which is scheduled every K units of age or L units of usage. This study is to meet products' availability requirement with the lowest cost by optimizing 2D PM strategy. A numerical example is provided to verify the effectiveness of the proposed policy. The results show that compared with age-based or usage-based PM strategy, 2D PM strategy is superior in terms of warranty cost and operational availability.

“…Equations (1)-(9) describe a basic optimization model. 2,15 Furthermore, the availability-based warranty model combined with imperfect PM and learning effects can be developed. Among them, a hybrid hazard rate model is used to describe imperfect PM actions, and learning effects including repetition learning and failure learning are considered during the maintenance process.…”

“…The proof of Theorem 1 is omitted here and a similar analysis can be found in Cheng et al 15 Although the closed-form solution is not available, the solution can be obtained using simple numerical search procedures. In summary, the flowchart for PM optimization under the availability-based warranty is presented in Figure 2.…”

By considering learning effects during the process of maintenance, this article investigates an availability-based warranty policy from the manufacturer's perspective. Imperfect preventive maintenance activities are implemented to reduce the number of equipment failures so as to meet the product's availability requirement and minimize warranty servicing cost during the warranty period. Hybrid hazard rate model is used to describe imperfect preventive maintenance actions; maintenance plan and warranty servicing cost are optimized by considering learning effects. Preventive maintenance schedule within a warranty period is optimized cycle by cycle, and the warranty cost rate is minimized under the requirement of availability within each cycle. Numerical example of a wind turbine gearbox is provided to verify the effectiveness of the proposed availability-based warranty policy. Sensitivity analysis shows that by considering learning effects on maintenance, the gearbox can maintain a higher availability level with a lower warranty cost than the case without consideration of learning effects.

Residual useful life (RUL) prediction is significant for condition-based maintenance. Traditional data-driven RUL prediction method can only predict fault trend of the system rather than RUL of a specific system component. Thus it cannot tell the operator which component should be maintained. The innovation of this paper is as follows: (1) Wavelet filtering based method is developed for early detection of slowly varying fault. (2) Designated component analysis is introduced as a feature extraction tool to define the fault precursor of a specific component. (3) Exponential life prediction model is established by nonlinear fitting of the historical RUL and the fault size characterized by the statistics used. Once online detection statistics is obtained, real-time RUL of the critical component can be predicted online. Simulation shows the effectiveness of this algorithm.
