Motivation
• Multidisciplinary design optimization requires collaboration
• How can software support this kind of collaboration?
• What if the collaboration needs to be done ad hoc?

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.

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

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

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

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
