  • Warranty Cost Modeling and Warranty Length Optimization Under Two Types of Failure and Combination Free Replacement and Pro-Rata Warranty

    The product warranty has become an indispensable facet of business operations. Burn-in is effective at eliminating infant mortality and improving operational reliability levels for consumers. This paper considers the influence of different failure states and different phases of product reliability and warranty policies on warranty costs from predelivery inspection to the end of the warranty period. We then propose a comprehensive warranty cost model that considers burn-in, free replacement warranty and pro-rata warranty as three phases for repairable products presenting two types of failure (minimal and catastrophic failure) that involve minimal repair and replacement, respectively. Warranty costs are the result of a combination of the three phases, where two types of failure occur individually or simultaneously. Moreover, we developed a framework for the modeling process of warranty costs, and the effects of various parameters, such as the burn-in time, warranty period, and distribution function on warranty costs, were analyzed. Finally, a practical case was examined by using a warranty cost model, and through an after-sales service data analysis, we obtained the failure rate distribution and optimal warranty length by minimizing the average warranty cost, which can serve as a reference for manufacturers when developing warranty policies.

  • A New Warranty Policy With Failure Times and Warranty Servicing Times

    We develop a new warranty policy with respect to the failure time and warranty servicing time, where those two variables are statistically correlated in bivariate distributions. Based on the developed approaches, we investigate the properties of the bivariate function, and obtain the number of warranty services in a warranty period using the field data. The warranty service includes the repair service, and replacement service. An approach of analyzing the warranty cost is proposed for a product in which the failure time and warranty servicing time are used simultaneously to determine the eligibility of a warranty claim. In the vast literature of the warranty modeling, the two- dimensional warranty is commonly consisting of the usage, and the age. In this study, we focus on the failure time and warranty servicing time as two factors under the warranty policy. Using the field data, the parameters are calculated, and the warranty model is investigated using a bivariate exponential distribution (BED) which was the best fit distribution based on the field data. Numerical examples are discussed to demonstrate the applicability of the methodology derived in the paper. The results of our research in this paper indicate that more sophisticated bivariate distributions other than the BED is worth the effort, as a future research problem, or using other data sets in a general industrial application setting.

  • Warranty Cost Analysis for <formula formulatype="inline"><tex Notation="TeX">$k\hbox{-}out\hbox{-}of\hbox{-}n$</tex> </formula> Systems With 2-D Warranty

    This paper presents new warranty cost models subject to two types of warranty periods (warranty and postwarranty periods), minimal repairs, and various types of warranty policies including free repair/replacement warranty and prorata warranty for _k_-out-of-_n_ systems. Two-dimensional warranty is applied to investigate the warranty cost using repair times and failure times. We obtain the long-run expected cost functions per unit time with respect to both the warranty and postwarranty periods by considering the aspects of both the manufacturer and the customer. This paper considers a periodic preventive maintenance (PM) policy with both corrective maintenance and PM and also determines three decision variables including warranty period, repair time limit, and periodical maintenance cycles, which minimize the long-run expected cost. Numerical examples are discussed to demonstrate the applicability of the methodologies, and results including the three optimum decision-variable solution and their corresponding long-run expected cost per unit are derived.

  • Cost information and decision-making of quality warranty in product design

    Warranty is an important part of new product development recent. Understanding and reducing warranty cost often focuses exclusively on the analysis of product design strategy which have a serious impact on the warranty servicing cost. Effective management of product warranty cost must take into account the link between warranty method and design strategy. Product design is a availability to at the first stage reduce warranty cost. This paper provides the cost information model and product quality warranty decision-making in product life cycle, and develops a cost model needed for effective management of warranty cost.

  • Prognostics-based product warranties

    Prognostics and health management (PHM) is an enabling discipline consisting of technologies and methods to assess the reliability of a product in its actual life cycle conditions and evaluate its remaining useful life. This paper presents the application of PHM methods as a proactive and predictive means to enable new warranty approaches. Warranty service is typically performed after the occurrence of failure. However, with the implementation of the predictive and proactive warranty strategies enabled by PHM, companies can make decisions for warranty returns up front. The prognostics-based warranty models developed in this paper include part-based warranty return, lifetime warranty, and customized extended warranty, and a case study of warranty validation and user abuse detection is also provided. The results of this work can increase the competitiveness of businesses by reshaping their warranty policies, improving their maintenance practices under warranty, and reducing their warranty costs.

  • Warranty servicing for special class of multi-state deteriorating products under renewing free-replacement warranty

    We develop a replacement-repair model to study a renewing free replacement warranty (RFRW) for a class of multi-state deteriorating repairable products. Each product may experience N different working states with different hazard functions, before the warranty contract expires. Once the item enters working state j(j = 1, 2,..., N), it can either fail or move t any of the subsequent states. In the former case, the best rectification action, replacement or minimal repair, regarding the failure status, should be done to put the item into operation. In each working state there is a determined probability for transition to each of the subsequent working states. After a replacement the product warranty is renewed. There are two parameters that affect manufacturer's decision to minimally repair or replace a failed item: the product deterioration level at the time of the failure and the remaining warranty time. In order to minimise the expected warranty servicing cost per item sold, we use a simulation based optimization method that combines discrete event simulation and experimental design. We include numerical example to illustrate the effectiveness of the proposed methodology.

  • Extended warranty policies with warranty options

    We consider a repairable system subject to two types of failures; minor and major requiring minimal repair and replacement respectively. Extended warranty models for the system that includes a free replacement period and an extended warranty period will be analyzed. Consumers have several warranty options during the extended warranty period. Explicit expressions for the manufacturer¿s long run average profit per unit time under these options are obtained. We also consider case of demand as a displaced log linear function of the product price, fixed warranty period and the extended warranty period. A numerical illustration is provided to demonstrate optimal product pricing and warranty period.

  • An empirical study on warranty improvements involving design teams

    An empirical study is conducted in this paper in order to evaluate the impacts of design teams on practices and performance of warranty, a signal of quality. Based on qualified 93 respondents from an investigation in 682 manufacturing companies in automobile, electronic and mechanic industries of China, involvements of design teams in warranty strategy makings are found to positively affect efforts of firms in warranty engineering practices, warranty service, organizational management and information technology application, so as to improve warranty performance of companies. However, participation of design teams has no significant influence on warranty cost management. Furthermore, firm size, firm industry, warranty type, and product diversity are selected as contingency factors, and impacts of them on warranty practices and performance are demonstrated.

  • A Repair Strategy Based on Minimal and Imperfect Repairs for Two-dimensional Warranty

    The costs from the servicing of warranty depend on the reliability of the product, the maintenance actions, and the servicing strategy. In this paper, we focus on a repair strategy based on minimal and imperfect repairs for two- dimensional warranty. We consider a rectangular warranty region with two measures (age and usage) and divide it into three disjoint sub-regions. The failed item is rectified by imperfect repair when it fails for the first time in the second sub-region of the warranty while all the other failures are repaired minimally. We derive the optimal values for these to minimize the total expected warranty cost. At last, we give an illustrative numerical example and compare with other strategies studied in the earlier literature to find the best repair strategy for two-dimensional warranty.
