支持协同设计的船舶设计过程模型研究 总被引:3,自引:1,他引:2
船舶设计过程模型是在网络环境下开展船舶并行和协同设计系统的基础.本文根据船舶设计的特点,提出了将船舶设计过程按照项目、设计任务和设计活动三个层次进行分解的方法,并给出了船舶设计过程模型形式化定义.该模型明确了设计任务间的并行、顺序和协同关系,可以直接按设计任务构成活动网络图进行规划、分析、管理等工作,使设计过程具有良好的可变更性和可控性. 相似文献

针对我国造船企业船舶建造质量管理体系不成熟、质量管理执行不坚决、质量管理缺乏科学方法的现状,在分析船舶建造质量管理特点的基础上,将任务分类技术应用于船舶建造质量管理,全面覆盖船舶设计、建造全过程,显著提升船舶一次报验合格率。经63 500 t散货船"ARIES CONFIDENCE"项目交付后的统计数据显示,该船最后一次报检合格率与以往同类船型相比提升了7. 86%,为后续项目推行基于作业任务分类的船舶建造质量管理模式提供宝贵的数据支撑。 相似文献

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, the decomposing principles of the ship design process and the architecture of the ship collaborative design (SDPM) system are presented. This method simplifies the activity network, makes the optimization and adjustment of the design plan convenient and also makes the design process easier to control and change, at last the architecture of the ship collaborative design system is discussed. 相似文献

The shipbuilding industry has adopted IT convergence as a new engine for growth encompassing conventional production know-how and economies of scale. Brand new solutions for enterprise IT, such as three-dimensional (3D) computer-aided design (CAD) systems, enterprise resource planning systems, and product lifecycle management systems have been adopted and customized to shipyards and contribute to productivity enhancement. As part of IT convergence in the shipbuilding industry, we examine the adoption of business process management (BPM) for the ship hull production design process. Ship hull production design, a process-based task, requires the most man-hours among all ship design processes and is directly coupled with ship production; thus, improvements in this task can contribute hugely toward enhancing productivity. First, we explain the concept of the executable model, which is an essential condition for executing defined processes in a business process management system (BPMS). In addition, we analyze the hull production design task and use this as the basis of a process to build executable BPM models. Thus, we present detailed implementations and the expected effects for the BPM execution of the hull production design process. The executable BPM model of the hull production design process is implemented using Bonita Open-Solution 5.5, a representative open-source BPMS. 相似文献
