The present invention relates to a method for deriving a calculation formula for obtaining the freeboard of a ship through a regression analysis and a method for calculating the freeboard by using the freeboard calculation formula. According to an embodiment of the present invention, the method for deriving a calculation formula for obtaining the freeboard of a ship by using a computer system includes the steps of: selecting two or more independent variables from formulas regarding the water drainage amount at 0.85D_mld, block coefficient at 0.85D_mld, freeboard depth, freeboard length, and variable named L_e; and deriving a correlation formula of the freeboard and the selected independent variables through a regression analysis of data of ships and deriving the freeboard calculation formula whereas the unit called D_mld represents a vertical distance from the upper surface of a keel to the upper surface of a freeboard deck near a side.

    본 발명은 회귀분석을 통해 선박의 건현 계산식을 도출하는 방법 및 상기 건현 계산식을 이용하여 건현을 계산하는 방법에 관한 것이다. 본 발명의 일 실시예에 따르면, 컴퓨터 시스템에 의해 선박의 건현 계산식을 도출하는 방법에 있어서, 0.85D에서의 배수량, 0.85D에서의 방형계수, 건현용 깊이, 건현용 길이, L에 관한 식들 중 적어도 두 개를 독립변수들로 선정하는 단계; 및 선박들의 데이터를 회귀분석하여 상기 선정된 독립변수들과 건현의 상관관계식을 도출하여 건현 계산식을 도출하는 단계를 포함하고, 상기 D은 용골의 상면으로부터 선측에서의 건현갑판 보의 상면까지 수직거리인, 선박의 건현 계산식을 도출하는 방법이 제공된다.
