Variable-complexity Multidisciplinary Design Optimization Using Parallel Computers
The use of multidisciplinary optimization techniques in aerospace vehicle design often is limited because of the signi cant computational expense incurred in the analysis of the vehicle and its many systems In response to this di culty a variable complexity modeling approach involving the use of re ned and computationally expensive models together with simple and computationally inexpensive mod...
متن کاملAerodynamic Optimization of a High Speed Civil Transport on Parallel Computers
A design methodology which uses a variable-complexity modeling approach in conjunction with response surface approximation methods has successfully been developed. This approach uses simple models to improve the accuracy of the response surface and reduce the number of analyses based on complex models required for constructing the surface. Simple models are rst used to eliminate \nonsense" port...
متن کاملA Coarse Grained Variable-Complexity Approach to MDO for HSCT Design
A parallel variable-complexity modeling approach, permitting the eecient use of emerging parallel computing in multidisciplinary optimization (MDO) technology, is presented for the particular instance of High Speed Civil Transport (HSCT) design. Simple analyses are used to limit the approximation domain in the design space. Points are selected within the approximation domain by a genetic algori...
متن کاملThe Multidisciplinary Design Optimization of a Reentry Vehicle Using Parallel Genetic Algorithms
The purpose of this paper is to examine the multidisciplinary design optimization (MDO) of a reentry vehicle. In this paper, optimization of a RV based on, minimization of heat flux integral and minimization of axial force coefficient integral and maximization of static margin integral along reentry trajectory is carried out. The classic optimization methods are not applicable here due to the c...
متن کاملA redundancy allocation problem with the choice of redundancy strategies by a memetic algorithm
This paper proposes an efficient algorithm based on memetic algorithm (MA) for a redundancy allocation problem without component mixing (RAPCM) in a series-parallel system when the redundancy strategy can be chosen for individual subsystems. Majority of the solution methods for the general RAPCM assume that the type of a redundancy strategy for each subsystem is pre-determined and known a prior...
