초록
제품의 품질이 동일할 경우 소비자가 품질보증기간이 긴 제품을 선호함에 따라 업체들은 보증기간 연장을 판매 전략의 하나로 삼아 경쟁사보다 경쟁 우위를 점하고 있다. 그러나 제품의 고장률이 높고 무상보증기간이 길면 길수록 제조사가 부담하는 보증 비용은 증가하고 제품 단가는 높아진다. 방위산업에서는 다양한 무기체계에 대해 동일한 보증기간을 요구하고 있으며, 보증 비용에 대해서는 객관적인 입증이 어려워 비용 반영이 잘 이루어지지 않고 있다. 따라서 객관적 보증 비용을 반영한 최적 보증기간 결정에 대한 연구가 필요하다. 본 연구에서는 불량률을 분석하여 개별 무기 시스템에 대한 적절한 보증기간을 산출하고, 보증기간 내의 보증 비용을 계산하였으며 향후 무기체계 개발단계에 대한 최적의 보증기간을 설정하는 과정을 제안하고 정부와의 합리적인 보증기간 설정을 위한 객관적인 근거를 마련할 수 있었다.
Abstract
As consumers prefer the product with longer warranty period if the quality is the same, companies are using the extended warranty period as one of their sales strategies to gain competitive advantage over rival companies. However, the manufacturer spending will increase when the product’s defect rate is high and the warranty period is longer. Accordingly, the price of the product will increase as well. For this reason, the determination of a warranty period becomes one of the critical decision making processes for the manufacturing companies. In this industry, equal warranty period is often required for various types of weapon systems, but as it is difficult to validate the warranty cost objectively, they are seldom reflected adequately. Therefore, a research on the objective method of determining the optimum warranty for the cost is warranted. In this study, the defect rate is analyzed to compute an adequate warranty period for individual weapon systems, and the warranty cost within the warranty period is calculated by applying a warranty cost model. This research proposes a process of setting an optimum warranty period for the development phase of weapon systems in the future, and establishes an objective ground for forming a reasonable warranty period with the government.
