Theoretical Fundamentals of Computer-Supported Collaborative Design in Structural Engineering

This document explores the integration of collaborative work aspects in structural design through the INDUSYS system. It examines the mapping of design processes to software systems, focusing on the anthropocentric components of teamwork. The paper presents an object-oriented approach using Unified Modeling Language (UML) and outlines a dual-system architecture comprising a process model for collaborative efforts and a structure-oriented product model. Additionally, it discusses practical applications such as the design of a water treatment plant, emphasizing the significance of advanced collaboration in civil engineering.

  1. Theoretical Fundamentals for Computer Supported Collaborative Design od Structures D. Hartmann and D. Bretschneider Department of Civil Engineering Institute for Computational Engineering Ruhr-University of Bochum Germany D. Hartmann / D. Bretschneider

  2. D. Hartmann / D. Bretschneider Introduction Can structural design, including the anthropocentric aspects of collaborative work, be mapped to a software system ?

  3. proof of practicability and serviceability through INDUSYS (INDUstrial SYStem) D. Hartmann / D. Bretschneider lFundamentals of INDUSYS lModeling of INDUSYS lApplication example

  4. (i)formalization and representation of the anthropocentric components of collaborative work (ii)computerized support for universally valid project management activities (iii)availability of a holistic and consistent product model of the structure to be designed l l l D. Hartmann / D. Bretschneider Fundamentals three basic features are most vital: complexity and dynamic nature require a generic, abstract reproducible and concise calculus of description ! accomplished through the object-oriented paradigm (OOP) utilizing the Unified Modeling Language (UML)

  5. l l l lcreate two separate subsystems, (i)a process model to represent team computing, independent of structural steel design (COOPERATE) (ii)a structure-oriented product model (PLAKON) D. Hartmann / D. Bretschneider solution approach: ltransform structural design into object classes and class diagrams lconcatenate both subsystems to an integrated system (INDUSYS) lvalidate and streamline the total system lenhance the system incrementally

  6. l l l D. Hartmann / D. Bretschneider Process model lprovides means of communication, coordination and cooperation lsupports the following subcategories of cooperation: reciprocal teamwork parallel teamwork sequential teamwork

  7. l l l D. Hartmann / D. Bretschneider lderived process model and management tools (according to UML)

  8. l l l D. Hartmann / D. Bretschneider Product model (for structural steel design) lsubdivided into the 4 cascading product submodels using OOM

  9. l l l D. Hartmann / D. Bretschneider illustration of the cascade of product submodels preliminary design

  10. l l l D. Hartmann / D. Bretschneider illustration of the cascade of product submodels structural analysis

  11. l l l D. Hartmann / D. Bretschneider illustration of the cascade of product submodels verification

  12. l l l D. Hartmann / D. Bretschneider illustration of the cascade of product submodels structural detailing

  14. l l l l l l D. Hartmann / D. Bretschneider lprocess of collaboration preliminary design: - P1 defines the basics of the structure - P1 decides on the team members by means of Team Editor - P1 + A1 + S1 determine load cases - product submodel of preliminary design

  15. l l l l l l D. Hartmann / D. Bretschneider structural analysis: - S1 computes structural response in terms of Stress-resultants - product submodel of structural analysis

  16. l l l D. Hartmann / D. Bretschneider verification: - P1 decomposes total work and defines Task-objects using Project-Editor - P1 + S1 are charged with the verification - product submodel of verification

  17. l l l D. Hartmann / D. Bretschneider structural detailing: - P1 + S1 + A1 + D1 + D2 are working together - P1 is charged with conflict resolutions - product submodel of structural detailing

  18. LAN D. Hartmann / D. Bretschneider lconflict resolution

  19. D. Hartmann / D. Bretschneider Conclusions CSCW-systems provide the potential to create sophisticated structural design l Computing opens further enhancements and improvements (e.g. multi-media inclusion) l implementation of soft issues (social models) is becoming attractive in engineering l new directions (e.g. multi-agent technology) and further research is required in the next years l
