Abstract

The leisure boat industry has the potential to become a high-value-added industry in the future. Recently, a study on Korean high-speed leisure boats for fishing was conducted. This study suggests a product configuration model-based shipbuilding cost estimation method for determining the type of leisure boat suitable for mass production, as part of a research for productivity improvement. The suggested estimation method based on the analysis of the leisure boat process and generic YWBS can calculate quantitative and concrete data. By using this method, the cost of building the catamaran-type design ship can be reduced by 17 times, compared to that of the monohull-type mother ship. This implies that the final design of the Korean high-speed leisure boat for fishing will have a competitive price at the actual production stage.

레저보트산업은 미래형 고부가가치 산업으로 최근 국내에서는 한국형 고속레저낚시보트에 대한 연구가 수행되었다. 본 논문에서는 고속레저낚시보트의 대량생산을 위한 기초연구로서 제품구성모델 기반의 건조공수 추정 연구를 수행하였다. 이를 위해 레저보트의 건조공정을 분석하고 범용 작업분류체계를 적용하였으며, 업체 설문조사를 통해 계층분석법 기반의 레저보트 건조공수 비례계수를 도출하였다. 또한 실적선의 공수를 기반으로 비례계수를 이용한 개발선 후보들의 정량적인 공수추정을 수행하였으며, 그 결과 실적선 공수 대비 17% 감소된 쌍동형 개발선을 최종 선정할 수 있었다. 이는 개발된 레저보트의 설계가 실제 건조단계에서 가격경쟁력을 갖출 수 있는 양산가능수준의 제품임을 의미한다.
