  • 1. www.DLR.de • Chart 1 > Ad hoc Collaborative Design... > Doreen Seider et al. Ad hoc Collaborative Design with Focus on Iterative Multidisciplinary Process Chain Development applied to Thermal Management of Spacecraft Doreen Seider, Achim Basermann, Robert Mischke, Martin Siggel, Anke Tröltzsch, Sascha Zur CEAS 2013 – Linköping, 17.09.2013
  • 2. www.DLR.de • Chart 2 > Ad hoc Collaborative Design... > Doreen Seider et al. Motivation • Multidisciplinary design optimization requires collaboration • How can software support this kind of collaboration? • What if the collaboration needs to be done ad hoc?
  • 3. www.DLR.de • Chart 3 > Ad hoc Collaborative Design... > Doreen Seider et al. Design Optimization in Thermal Management of Spacecraft • Objective: Design with maximum glide ratio • Contraints: Upper mass, fixed trajectory
  • 4. www.DLR.de • Chart 4 > Ad hoc Collaborative Design... > Doreen Seider et al. Using Multidisciplinary Process Chain • Process chains consist of multiple tools representing disciplines • Executed automatically • Integration Frameworks widely used
  • 5. www.DLR.de • Chart 5 > Ad hoc Collaborative Design... > Doreen Seider et al. Demand for Ad hoc Collaboration in Multidisciplinary Process Chain Development • In early design phase the process chain is set up when tools are still under development • Used integration framework must enable the user to use tools of other disciplines • • • • easily in the latest version, from remote, and ad hoc.
  • 6. www.DLR.de • Chart 6 > Ad hoc Collaborative Design... > Doreen Seider et al. Integration Framework RCE fuselage .py engine .f77 wings .c
  • 7. www.DLR.de • Chart 7 > Ad hoc Collaborative Design... > Doreen Seider et al. Integration Framework RCE
  • 8. www.DLR.de • Chart 8 > Ad hoc Collaborative Design... > Doreen Seider et al. Network and Communication in RCE • Typical client-server model results in quite static network layouts • Network of RCE is based on peer-to-peer approach RCE installation Direction of initialization C…Compute nodes R…Relays U…User frontend machines
  • 9. www.DLR.de • Chart 9 > Ad hoc Collaborative Design... > Doreen Seider et al. Ad hoc Distribution of Tools with RCE • Tools are integrated into RCE in a declarative way • Tools are always executed on the machine the corresponding RCE installation is running • Once the corresponding RCE installation get part of an RCE peer-to-peer network, the tool can be used by others
  • 10. www.DLR.de • Chart 10> Ad hoc Collaborative Design... > Doreen Seider et al. Ad hoc Distribution of Optimization Methods with RCE • RCE can be extended with custom optimization methods • Again, optimization methods are always executed on the machine the corresponding RCE installation is running • Again, once the corresponding RCE installation get part of an RCE peerto-peer network, the optimization method can be used by others
  • 11. www.DLR.de • Chart 11> Ad hoc Collaborative Design... > Doreen Seider et al. Conclusions • Demand for ad hoc collaboration in early design phase during process chain development • Experiences made with RCE as integration framework supporting ad hoc collaboration • It is the right way to go • But: Technical support with the help of software doesn‘t solve the human challenges regarding collaboration
