The reliability of supply of the logistics systems is the one of the most important factors determining the competitiveness of businesses. The main purpose of this paper is to assess the reliability of supply of a given system with the use of warranty analysis, based on the Nevada chart. The reliability analysis performed is done in the following way: shipping and warranty return data of a given supply system are converted into a classic data form. Then, the life data analysis is performed, which allows to obtain the given reliability indicators and predict the future returns of the products and services. The paper consists of some useful reliability measures, that may be used in the assessment of reliability for the supply system. Used reliability indicators may be the basis for the development of the preventive tasks to reduce the future returns. The presented approach for reliability assessment of supply system discloses its applicability. Forecasting the future returns and determining the selected reliability measures may be applied in any supply system. It is valuable for the identification of the weakest product or service and it is necessary for developing further preventive activities.

“…One typical method is to directly put forward the standard bivariate distribution functions to model product failures under 2D warranty, for example, bivariate Pareto and Beta Stacy distributions, 33,40,66 bivariate exponential distribution, 35,49,67,68 bivariate Weibull distribution, 47,69,70 and bivariate Paulson distribution. 66 On the other hand, some research derives the bivariate density functions by explicitly modeling usage as a function of time. For example, Singpurwalla and Wilson 29,71 and Eliashberg et al 72 incorporated the effect of usage on time to failure with an additive hazard model.…”

The warranty policies for capital-intensive products, such as automobiles, heavy equipment, and aircraft engines, typically have two dimensions, that is, the age and usage. During the last two decades, much research has been published on the two-dimensional warranty from many different perspectives. This article reviews and summarizes work and state-of-theart developments in this research field, with emphasis on both theoretical methodologies and practical applications. In this review, five principal topics are covered: (1) two-dimensional warranty policies, (2) cost analysis of two-dimensional warranty, (3) two-dimensional warranty and engineering/marketing problems, (4) two-dimensional warranty and logistics issues, and (5) two-dimensional long-term warranty. In particular, the practical and application aspects of twodimensional warranty policies have been surveyed. Overall, 105 journal papers covering 49 journals, published from 1993 to present, are selected and discussed in detail. Finally, some interesting and challenging research topics are presented for the scholars and practitioners to explore new research in this field.

“…Existing researches on warranty management focus mainly on the warranty policies for standard products. [7][8][9][10] For some complex mechatronic products, including CNC machine tools, wind turbines, and engineering machinery, they are expensive and key devices for their users, and their failure or shutdown may result in serious production loss. Therefore, availability is an important performance index for such kinds of equipments, and it is crucial to incorporate availability requirement into warranty terms.…”

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.
