Shipyard hoisting process is a project type manufacturing process which entails more sophisticated elements and relationships than other kinds of processes, this feature brings particular challenges when constructing a structured description of the process, called enterprise model, to introduce various Computer Integrated Manufacturing (CIM) technologies. However, most of the modelling methods devised so far do not consider the individual demand of project type manufacturing process. Therefore, we envisage the necessity to expand, extend, and refactor current methodologies in order to exploit this remaining dimension. In this line, we present a dedicated method aiming at appropriately modelling the project type manufacturing process, it employs seven collaborative views and task-centric idea to emphasize work flow abstraction without sticking to the material flow abstraction as current methods do, which is the key factor to successfully achieve horizontal functions/organizations integration and vertical management hierarchies integration for this special process. The proposed method adopts semi-formal meta model to interpret its framework, building blocks and constraints graphically and rigorously. All these works are performed taking shipyard hoisting process as example. According to the modelling method, a two-stage Computer Aided Process Planning (CAPP) method is also initiated to demonstrate how the process model can serve as the bridge to converge manufacturing technology and information technology. Furthermore, a CAPP prototype is developed to carry out case study with an actual shipyard hoisting process. The study reveals promising contributions to not only enhancing the industrial competitiveness but also enriching the enterprise modelling research on project type manufacturing process.

以任务为中心的船厂起重过程建模方法及其在CAPP中的应用

造船厂起重过程是一种项目类型的制造过程,与其他类型的过程相比,它需要更复杂的元素和更多的关系,在构建过程的结构化描述(称为企业模型)以引入各种计算机集成制造(CIM)技术时,此功能带来了特殊的挑战。但是,到目前为止设计的大多数建模方法都没有考虑项目类型制造过程的个别需求。因此,我们认为有必要扩展,扩展和重构当前的方法,以利用这一剩余的维度。在这一行中,我们提出了一种专用于对项目类型制造过程进行适当建模的方法,它采用七个协作视图和以任务为中心的思想来强调工作流抽象,而不像当前方法那样坚持材料流抽象,这是成功实现此特殊过程的横向职能/组织集成和纵向管理层次结构集成的关键因素。所提出的方法采用半正式元模型以图形方式和严格方式来解释其框架,构造块和约束。所有这些工作都是以船厂起重过程为例进行的。根据建模方法,还启动了一个两阶段的计算机辅助过程计划(CAPP)方法,以演示过程模型如何充当融合制造技术和信息技术的桥梁。此外,开发了CAPP原型,以通过实际的船厂起重过程进行案例研究。这项研究揭示了不仅对增强工业竞争力,而且丰富了项目类型制造过程中的企业模型研究的有希望的贡献。
