船舶设计过程模型的基础是网络环境下开发的船舶协同设计系统。根据船的设计特点，划分为船舶设计过程分为三个层次的方法是轻拍着，那就是方案层，设计任务层和设计活动层，然后将船舶设计过程模型的形式化定义-The ship design process model is the basis for developing the ship collaborative design system under network environment. According to the characteristics of the ship design, a method for dividing the ship design process into three layers is pat forward, that is project layer, design task layer and design activity layer, then the formalized definitions of the ship design process model
