Abstract: The characteristics of design alternatives of navy vessels are analyzed. Based on the understanding to the evaluation and the criterion system of design alternatives, the synthesis of criterions is explored. The measure of bottom criterions is researched. The simplification of integration measurement to a part of bottom criterions is presented. They can be used to the evaluation, trade off and optimization of design alternatives of navy vessels. In the paper, their condition of use and how to use the assessment methodology are analyzed.
