A Study on Quality Policy and Warranty Cost in Multi-components Assembly Product

다수부품(多數部品) 조립제품(組立製品)의 품질정책(品質政策)과 보증수리비(保證修理費)에 관한 연구(硏究)

Warranty cost usually involves complex factors paticularly when the product concerned consists of a great deal of parts. In spite of that it can be assessed by means of rather simple mathematical expression, it is possible to realistically appraise the sensitivity to any type of quality policy. This paper thus presents the mathematical concept related to the warranty cost and the general relationship showing that quality policy can be established in connection with the economic quality level.
