  • Jung et al.(2015) suggest the two-phase warranty model, which is a general type of warranty model. Under the two-phase warranty, the warranty period is divided into two intervals, one of which is for renewing replacement warranty, and the other is for minimal repair warranty. And warranty policies play a very important role in product marketing. In this paper, we suggest the optimal warranty policy for free extended two-phase warranty. To determine the optimal warranty period, we adopt the expected profit per unit product. So, the expressions for the total expected cost, the sale price and the expected profit per unit product from the manufacturer's point of view are derived. Also, we discuss the optimal warranty period and the numerical examples are provided to illustrate the proposed the warranty policy.

  • Purpose - Numerous studies have tried to assess the role of a warranty as an explanatory instrument for product quality. While one study argued that manufacturers signal their superior quality to consumers by extending the duration of a warranty, quality is not necessarily related to warranty and a warranty for a short duration is a sign of high product quality. However, there are limitations to measuring product quality in terms of a single variable such as a warranty. Some other studies have evaluated the influence of brand power or value and price on the supposed quality of a product while the influence of warranty was found to be insignificant. Research design, data, methodology - The study analyzes the influence of brand power and the country of origin effect on consumers' perception of product quality in line with warranty and establishes a priority strategy. Especially, consumer experience has a significant influence on state of the art technology products like applied home electronics as these goods are generally quite expensive and consumers expend significant energy in purchasing them, so the associated warranty and brand can have a critical role in the decision making process. The price of the product was excluded in this discussion as it continually varies with the market share of the product. Results - The results of the analysis are as follows: First, each of the factors such as the standard of the warranty, brand power, and country of origin effect influences the degree of satisfaction of an individual. Second, the factors brand power and quality of the warranty interact both complementarily and synergistically at a time, depending on the brand power. As brand power is more significant, the degree of satisfaction is greater in case of products with low quality warranty compared to those with high quality warranty. Third, the brand power and country of origin effect present a complementary interaction. Fourth, the country of origin effect and quality of a warranty interact synergistically. Conclusions - Thus, the higher the quality of warranty, greater is the increment in the degree of satisfaction. The comprehensive study on the effect of the country of origin on the purchase decision process and the degree of satisfaction compared to the other elements shows that in case of Japanese and Korean markets the brand power of a company is desirable in sustaining the quality of warranty to the industrial average. Also, there is no significant improvement in the perceived quality of the product when the quality of the warranty is lowered. Therefore, the warranty effect diminishes when the value of the brand is known, while it perishes when both the brand power and the country of origin effect are strong enough.

  • After the buyer purchases the product, the seller's role does not end. If the product fails to function properly before the end of the warranty period, the seller is responsible for its repair or replacement under the seller's warranty policy. There are two common types of warranty policies: the free replacement warranty and the rebate warranty. Under the free replacement warranty policy, replacement or repairs during the warranty period are provided by the seller free of charge to the buyer. Under the rebate warranty policy, a failed item is replaced by a new one or is repaired at a cost to the age of the failed item. The rebate warranty is most often used for items such as a battery or an automobile tire which wear out and must be replaced at failure. This paper proposes a easy way of estimating the warranty cost under the free replacement warranty policy assuming an exponential product failure function on repairable products.

  • In this paper, an evaluation of a product replacement ratio of irreparable items to the normally working ones is performed with a view to a warranty analysis. It is demonstrated that the replacement ratio during the warranty period can be estimated from the field data collected during the period of operation, and one can provide the management with a useful information regarding the appropriateness for the warranty period, which is vital to the product marketing strategy. Although warranty data usually take the form of multiply right censored interval data, the conventional reliability analysis method seems to be good enough as in this case. More sophisticated method such as warranty cost analysis and 2-dimensional warranty analysis is yet desired.

  • The market for second hand products has been growing for a variety of reasons (e.g., new products appearing at a faster rate and the expected life of products increasing due to rapid advances in technology). The demand for warranties for second-hand products has been growing along with the growth of the market for second-hand products. Warranty for new products (consumer durables, industrial and commercial, and specialized defense products) has received a lot of attention. In contrast, warranties for second-hand product have received very little attention. Often, dealers of second-hand product such as cars offer 2D-warranties (Year and Kilometers). The expected warranty cost associated with a second-hand product for 2D-Policies is a function of the age of the item and its usage (as it affects failures over the warranty period), the warranty terms and the servicing strategy used by the dealer. This paper deals with development of models for warranty cost analysis along with the decision on sale price and warranty cover for 2D-Warranty policies associated with sale of second-hand products.

  • A warranty is a contractual obligation incurred by a producer in connection with the sale of a product. The warranty specifies that producer agrees to remedy certain failures in the product sold. There have been many articles dealing with warranties, but they have studied about optimal warranty cost for the warranty period. In this study, an optimal preventive maintenance time interval is computed. The optimal preventive maintenance time interval minimizing warranty cost for the warranty period is discussed. It is assumed that failure rate is increasing and the failure rate after preventive maintenance or corrective maintenance lies between good as new and bad as old.

  • This paper proposes a new two-dimensional warranty policy with replacement and repair regions and analyses the warranty cost under the new warranty policy. The product is sold under a two-dimensional warranty(usage and age) in which two regions exist : the failed product is replaced by the manufacturer in the replacement region or minimally repaired by the manufacturer in the repair region. The formula of the expected warranty cost under some assumptions about usage and failure is obtained. Numerical examples are studied.

  • Purpose: The purpose of this research is to study research trend in the field of warranty and maintenance policy of second-hand products. Methods: To this end, we consider research articles, which deal with warranty and maintenance of the second-hand products, published on journals during the past 20 years and classify them by taxonomy scheme proposed by Shafiee and Chukova (2013). The taxonomy scheme consists of three maintenance models in warranty for second-hand product. In each models, we analyze proposed maintenance and warranty policies with respect to types of upgrade models, types of preventive maintenances, decision variables and decision criteria model. Results: We obtain the scheme of maintenance and warranty of the second-hand products and define cost related to warranty and maintenance of the second-hand item. Also, we summarize the characteristics of maintenance and warranty policies in each classified model. Conclusion: There have been several research reviews on maintenance and warranty polity of new products. This research surveys researches of authors during the past 20 years and classifies, summarizes and compares proposed maintenance and warranty policies of the second-hand products. This research provides useful information to researchers who are interested in maintenance and warranty of the second-hand products.

  • 본 연구는 제품보증의 유형인 명시적 보증과 묵시적 보증이 소비자의 제품에 대한 태도에 미치는 영향을 제품보증과 관련된 선행연구들을 탐색하여 살펴보았다. 이에 따른 주시험 효과가 제품유형(탐색재 vs 경험재) 및 제조업체의 기업윤리 수준(고윤리 vs 저윤리)에 의해 조절되는지를 상호작용 효과의 차원에서 고찰하였다. 실증분석 결과에 의하면 소비자의 제품에 대한 태도는 제품보증이 명시적일 때가 묵시적일 때보다 높게 나타났다. 그리고 제품보증의 유형에 따른 주시험 효과는 해당 제품이 탐색재일 때보다 경험재일 때가 더 크게 나타났으며, 제조업체의 기업윤리 수준이 높을 때보다 낮게 인식할 때가 더 크게 나타났다. 다만, 이러한 조절효과는 두 가지 종속변수 중 제품태도는 통계적으로 유의한 결과를 보이지 않았고 구매의도에서만 유의한 결과가 나타났다.
