An Ontology-based Method for Process Modeling in MultiDisciplinary Collaborative Design

Abstract

Process modeling is an important task for collaborative design of a multi-disciplinary nature. This paper proposes an ontology-based method to model the collaborative design process. The aim is to effectively coordinate, allocate and share design resources. Concepts of task, sub-task, and local ontology in the collaborative design environment are defined. The tasks of achieving optimal resource allocations of design resources are divided into sub-tasks that are stored in the form of local ontology. Genetic algorithm is employed in match-researching among local ontology and different disciplines. Tasks and their discipline views are described in the ontology-enabled semantics-sharing of design resources in multi-disciplinary collaborative design. Process modeling of a missile is used as an example to demonstrate the capabilities of the proposed method and framework. 2014 SERSC.
