为缓解船舶对环境的污染，实现船舶动力系统的绿色设计，通过研究船舶动力系统全生命周期绿色设计流程，确定了船舶动力系统绿色设计系统边界，构建了船舶动力系统的全生命周期绿色度评价指标体系.在考虑评价指标之间相互作用关系的基础上，综合利用Delphi法和网络分析法，建立评价指标超矩阵并对之求极限，确定了船舶动力系统绿色度评价体系中各指标的综合权重.参照某现役船舶动力系统，对所提出方法进行验证，并针对不同绿色设计方案进行解释说明，为船舶动力系统的绿色设计评价提供了新的方法.
In order to reduce the pollution of ships to the environment and realize green design of the marine power system, this paper establishes the boundary of system and presents a life cycle assessment scheme of this system. Taking into account the interaction between evaluation indicators, we utilize Delphi method and analytic network process to determine the weight for each indicator of marine power system by establishing an evaluation index super-matrix and finding its limit. The methods proposed in the paper are verified by analyzing a current marine power system and explaining different green design schemes, and they provide a new approach to green design assessment of the marine power system.
