Implementation of an executable business process management model for the ship hull production design process船体生产设计过程里实施可执行的业务流程管理模型


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.

造船业采用IT融合作为增长的新引擎,包括传统的生产技术和规模经济。企业IT的全新解决方案,如三维(3D)计算机辅助设计(CAD)系统,企业资源规划系统和产品生命周期管理系统已被采用并为船厂定制,有助于提高生产力。作为造船业IT融合的一部分,我们研究了船体生产设计过程中业务流程管理(BPM)的采用。船体生产设计是一项基于过程的任务,在所有船舶设计过程中需要最多的工时,并且直接与船舶生产相结合;因此,这项任务的改进可以极大地提高生产力。首先,我们解释可执行模型的概念,这是在业务流程管理系统(BPMS)中执行已定义流程的基本条件。此外,我们分析船体生产设计任务,并将其作为构建可执行BPM模型的流程的基础。因此,我们提出了船体生产设计过程的BPM执行的详细实施和预期效果。船体生产设计过程的可执行BPM模型使用代表性的开源BPMS Bonita Open-Solution 5.5实现。


In this study, we analyzed the ship hull production design process from the perspective of a business process. We present a detailed procedure for executing this process in a business process management system (BPMS). As an introduction to the research topic, we briefly introduce business process management (BPM) and the shipbuilding process.

在这项研究中,我们从业务流程的角度分析了船体生产设计过程。 我们提供了在业务流程管理系统(BPMS)中执行此过程的详细过程。 作为研究课题的介绍,我们简要介绍了业务流程管理(BPM)和造船过程。


After a ship is ordered, the shiprsquo;s design process is divided into basic design, detail design, and production design as shown in Fig. 1. Through each design phase, the design becomes more sophisticated and specific, so the output of the final production design phase is good enough to be used in the shiprsquo;s production. The basic design process, which aims to make key plans and main documents and building specification, is sufficiently covered academically in undergraduate courses on naval architecture and ocean engineering. Detailed design includes the hull and the outfitting, which is separate from the functional classification of a ship. In this paper, we focus on the hull design.

订购船舶后,船舶的设计过程分为基本设计,详细设计和生产设计,如图1所示。通过每个设计阶段,设计变得更加精密和具体,因此最终生产设计的输出 阶段足以用于船舶的生产。 旨在制定关键计划和主要文件以及建筑规范的基本设计过程在学术上充分涵盖了船舶结构和海洋工程的本科课程。 详细设计包括船体和舾装,它与船舶的功能分类是分开的。 在本文中,我们专注于船体设计。


Because a hull detail design is performed for each major compartment of a ship according to strength calculations based on structural analysis of the entire ship and local structures [1], it is single task-level work rather than process-based work. Concretely, hull detail design refers to designing two-dimensional drawings of the hull structure using predefined symbols and lines for each compartment; depending on the type of ship, these compartments have structural consistency or are separated by functionality. These compartments can be parts of a ship, such as the engine room, main deck, bow, or stern, or structural modules with special functions, such as the shaft strut, funnel, or sea chest. The resulting construction of a ship hull detail design is based on key plans such as the general construction, general arrangement, and mid-ship section that are outputs of basic design. The construction includes details such as the position and specifications of stiffeners, end cut method, bracket, and collar plate for a cutting hole to ensure sufficient structural strength. Depending on the type of ship, there may be 20–50 construction tasks, but they are not issued and completed simultaneously. The construction is begun and issued sequentially according to the manpower capacity of the hull structural design team or to secure structural consistency between compartments. The construction that is done on the basis of the hull detail design cannot be completed only from the design and structural analysis of the corresponding hull structure. It also requires confirmation from relevant co-workers in the outfitting design team, review from the design part manager, and approval from the ship owner. Therefore, depending on the work difficulty and the correlation with the relevant team, this process may take 1 month to 1 year to complete. The construction is in the form of a large print drawing, such as A0 or A1 size, and may exceed 7 m in length in certain cases.


Hull production design is a final-stage design and acts as a bridge between design and production. Hull production design is closely related to the facilities a
