Development of an agent-based workbench supporting collaborative structural design

Abstract: This paper presents an approach towards an adaptive, expandable, decentralized and flexible workbench supporting complex structural design processes using multiagent systems technology. Primarily, this novel workbench aims at assisting design experts according to their specific tasks during a project work and furthermore detecting typical deficiencies and conflicts that may occur in collaboration, cooperation and coordination between the various structural designers. The workbench consists of a set of software agents, that are designed and modeled to integrate typical organizational characteristics of a project work, engineering software and data structures in terms of product models. According to the analysis of structural design processes a theoretical concept of three agent-based submodels is suggested: i) the agent-based collaboration model, ii) the agent-based engineering software integration model and iii) the agent-based product model. In this paper we focus on the agent-based collaboration model. The three models are connected by an agent-based process model. The fundamental solution concepts of this approach are to be substantiated by analyzing the design process of an arched bridge, already erected, as a reference.

Integrated Multiagent and Peer-to-Peer based Workflow-Control of Dynamic Networked Co-operations in Structural Design

Abstract: Modern engineering projects in the application domain of structural design are organized in networked co-operations due to permanently enlarged competition pressure and a high degree of complexity while performing concurrent design activities. One of the major challenges of these networked co-operations constitutes the coordination of the activities of all involved participants. In the course of our common research activities, we have developed two different directions for coordinating these projects: i) a workflow-based concept regulating the activities explicitly by a global workflow model (University of Bochum) and ii) an awareness model that allows to perceive activities of other protagonists and to derive new activities mentally. This paper describes a novel integration approach of these two models: according to the global workflow model, users can be connected through awareness channels that enable them to detect potential inconsistencies during their concurrent modeling activities. Inconsistencies that would otherwise remain in the project progress can thus be discovered at a very early stage.
