Motivation

• Multidisciplinary design optimization requires collaboration

• How can software support this kind of collaboration?

• What if the collaboration needs to be done ad hoc?

• Objective: Design with maximum glide ratio • Contraints: Upper mass, fixed trajectory

Using Multidisciplinary Process Chain

• Process chains consist of multiple tools representing disciplines • Executed automatically • Integration Frameworks widely used

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

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 peer-to-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
