Recently, structural design of ships and marine structures considering various risks in the lifecycle of the structure has become more and more important. It is said that sustainability of ships and marine structures should be evaluated when the structure is constructed based on assessment of "holistic risk" which includes assessment of safety, environment, social responsibility and etc. Based on the concept of holistic risk evaluation, we proposed a framework of lifecycle structural optimization considering various risks such as failure risk and environmental risk. Also, in this study, we investigated the method to evaluate uncertainty of structures which is necessary for assessment of failure risks.

近年来，考虑结构生命周期中各种风险的船舶和海洋结构物的结构设计变得越来越重要。船舶和海洋结构物的可持续性评价应基于“整体风险”进行，包括安全、环境、社会责任等。基于整体风险评价的概念，提出了考虑失效风险和环境风险等多种风险的全寿命周期结构优化框架。此外，在这项研究中，我们研究的方法来评估结构的不确定性，这是必要的失效风险评估。
