Consistent Development of Automated Material Flow Systems using a model-based Approach

在自动化系统的开发过程中，如制造货物的连锁生产系统或运输货物的自动化物流系统等多个部门(销售、开发等)和学科(机械工程、电气工程等)是并行的还是顺序的。不同的涉众对同一项目使用不同的设计模型和工具，每个设计模型和工具都描述了与相应规程相关的部分方面。每个利益攸关方都有自己对项目的看法，仅限于模型中与各自利益攸关方就其个别任务开展工作有关的那些方面。然而，由于不同利益攸关方的相关方面部分重叠或相互影响，目前常见的做法是在另一个利益攸关方的建模工具中重新建模一个利益攸关方的模型的各个部分。但是，如果在开发阶段进行更改，可能会导致不同模型之间的不一致。以自动化物流系统(AMFS)为例，本研究项目旨在研究和开发信息技术方法和模型，以实现高效、跨学科的协作。开发的信息技术方法将不同的模型联系在一起，并自动检测模型之间的不一致。在检测到不一致之后，实施的规则定义了对不一致的反应，并提供了解决这些不一致的行动建议。与AMFS的运行时模型不同，本研究项目侧重于设计模型。来自信息技术领域的V-SUMM方法似乎适合于保持不同模型之间的一致性，并在aMFSS的开发和演化中改进它们的集成。例如，在开发AMFS期间使用的多个元模型(例如CAD模型)之间定义一致性和对应规则。特别是，V-SUMM方法支持生成组合视图。例如，CAD(布局)和UML(逻辑)模型元素之间的关系是可见和可更改的。本研究项目为MFSS定义了一个V-SUMM，以实现开发过程中的连续工作流，以便在早期阶段发现设计模型之间的不一致，并使设计模型能够跨多个学科和项目重用。所提出的方法并不是完全自动化了多学科专家系统的开发过程，而是在开发过程中支持了人力利益相关者，并且避免了已经建模的知识的人工转移。

In the development process of automated systems such as interlinked production systems to manufacture goods or automated material flow systems to transport goods several departments (Sales, Development, etc.) and disciplines (mechanical engineering, electrical engineering, etc.) are involved in parallel or sequentially. The various involved stakeholders use different design models and tools for the same project, each of which depicts partial aspects relevant for the respective discipline. Each stakeholder has its own view of the project, which is limited to those aspects of a model that are relevantto the respective stakeholder for working on its individual task. However, since relevant aspects of different stakeholders partly overlap or influence each other, it is currently common to re-model parts of one stakeholder’s model in another modelling tool for another stakeholder. If changes are made during the development phase, however, this may lead to inconsistencies between the different models. Using the example of automated material flow systems (aMFS), this research project aims to investigate and develop information technology methods and models, which enable an efficient, cross-disciplinary collaboration. The developed information technology methods link the different models together andautomatically detect inconsistencies between the models. After the detection of inconsistencies, implemented rules define reactions oninconsistencies and provide recommendations for actions to resolve these inconsistencies. In contrast to run time models of aMFS, this research project focuses on design models. The V-SUMM approach from the information technology domain seems suitable to maintain consistency between different models and to improve their integration in the development and evolution of aMFSs. For example, consistency and correspondence rules are defined between the multiple meta-models used during the development of aMFS, such as CAD models. In particular, the V-SUMM approach enables the generation of composed views. For example, the relationships between CAD (layout) and UML (logic) model elements are made visible and alterable. This research project defines a V-SUMM foraMFSs to realize a continuous workflow during development, todetect inconsistencies between design models at an early stage and to enable the reuse of design models across several disciplines and projects. The proposed approach does not completely automate the development process of aMFSs, but supports the humanstakeholders during the development process and manual transfer of knowledge that has already been modeled is avoided.
