The purpose of this study is to propose the accurate and simple reliability based design method adjusting the distribution shapes by means of high order moment. In this paper, we propose the high order moment standardizing method, and define a reliability index using the proposed method. Firstly, the high order moment standardizing method, which is able to treat random variables handly, is proposed by using the high order mement, and the proposed method is evolved into the third order moment standardizing mehtod concretely. The high order moment standardizing function is defined in the form of a series with undetermined coefficients. The coefficients are determined by using the information of the high order moments of random variables. Secondly, the reliability index based on the proposed method is defined. The reliability index is composed of the high order moments, which are offered by a finite number of data in the same manner as a mean or a standard deviation. The proposed method is very effective and useful method adjusting the asymmetry or skewness of the distribution shape, even if the statistical data are not given enough to determine the distribution functions of random variables exactly
