Inconsistency Management in Heterogeneous Models - An Approach for the Identification of Model Dependencies and Potential Inconsistencies

Abstract

In today's engineering projects, interdisciplinary work leads to an increase in interfaces between different departments and domains. As each stakeholder pursues different goals and tasks, a heterogeneous model landscape is required. In each domain, a variety of different model and software implementations provide the essential basis for efficient work. On the interfaces, the risk of model inconsistencies increases. To handle occurring inconsistencies, various approaches have been presented. For model-based systems engineering projects, rule-based methods are considered as the most suitable technique. However, said approaches require a high manual effort in identifying model dependencies and establishing consistency rules. Unfortunately, in particular these steps are not well described and supported. Therefore, this paper presents an easily applicable approach for the identification of model dependencies in interdisciplinary projects. The method is supported by a software implementation and is directly integrated in engineering workflows. A first industrial case study has shown positive effects of the approach and revealed further research goals.

“…Temperatureinflüsse) erforderlich. Für eine durchgängige Lösungsbeschreibung ist eine Verknüpfung domänenübergreifender und domänenspezifischer Modelle notwendig [4,5]. Fehlende Ansätze domänenübergreifende und -spezifische Modelle konsistent zu verknüpfen, resultiert in geringer Akzeptanz domänenübergreifender Sprachen, auch weil die erforderlichen Abstraktionen bestehender domänenspezifischer Modelle zeitaufwändig sind [6].…”

“…Heterogene Modelle sind ein Ansatz, unterschiedliche Modellelemente in eine Präsentation zu integrieren und damit die Konsistenz von Produktinformationen im Entwicklungsprozess zu verbessern. Gleichzeitig muss die Konsistenz sowohl innerhalb der Modellpräsentation als auch -repräsentation sichergestellt werden [4].…”

“…Die Heterogenität in Modellen drückt sich durch unterschiedliche Faktoren aus. Auf Basis einer Literaturrecherche konnten folgende Faktoren der Heterogenität in einer modellbasierten Entwicklung identifiziert werden [4,12,15,18,19,20]:…”

Mbse Within the Engineering Design Community – An Exploratory Study

“…Models are central to documenting results, applying simulations, analysing different solutions, and transferring knowledge in different engineering activities. When engineering modern systems involving services and subsystems from various engineering domains different perspectives have to be addressed resulting in a heterogeneous model landscape (Kattner et al 2019). The different models represent aspects of the system under development and are characterized by diverse presentations and data structures.…”
