TY - CONF A1 - Lockan, Michael A1 - Bestle, Dieter T1 - A Concept for Collaborative Design and Distributed Optimisation T2 - 5th IC-SCCE International Conference: From Scientific Computing to Computational Engineering, Athen, 2012 N2 - The paper shows a methodology for designing a complex system in a collaborative design environment by sharing information on autonomous subsystems and coupling parameters. Collaborative design is a current issue in aviation industry where intellectual property rights of individual companies prohibit a common evaluation model. State of the art approaches based on nested local optimisation loops are not sufficient if time-consuming component analyses are involved. A new approach for collaborative design is developed where the overall optimisation of a complex system is split into subsystem optimisation problems. Coupling parameters are treated as local design variables and only optimal coupling parameters are exchanged regularly. Application to a test example shows a huge time reduction and improved probability for finding the global optimum. Advantages are also demonstrated for an industrial design task.
