A surrogate based multistage-multilevel optimization procedure for multidisciplinary design optimization

Optimization procedure is one of the key techniques to address the computational and organizational complexities of multidisciplinary design optimization (MDO). Motivated by the idea of synthetically exploiting the advantage of multiple existing optimization procedures and meanwhile complying with the general process of satellite system design...

Uncertainty multidisciplinary design optimization of distributed space systems

The design of Distributed Space Systems (DSSs) is a challenging task, especially in the conceptual design stage where unknown or uncertain information extensively exist. This paper investigates the problem of designing DSSs in the presence of uncertainties. The uncertainties associated with DSSs are discussed. It is shown that DSSs are...

Utilizing Uncertainty Multidisciplinary Design Optimization for Conceptual Design of Space Systems

With progress of space technology and increase of space mission demand, requirements for robustness and reliability of space systems are ever-increasing. For the whole space mission life cycle, the most important decisions are made in the conceptual design phase, so it is very crucial to take uncertainties into consideration in this initial...
