A Study on Parameter Steering Method for Design Optimization

The design optimization technology for aircraft is increasingly complex. It is neces- sary to study design optimization visualization to popularize optimization technology and improve design quality and efficiency. The parameter steering method for design optimization is presented to solve problems in the primary design phase, such as absence of design knowledge and difficulty to get primary schemes quickly. It gives a convenient means of analyzing parameter sensitivity and is intuitive to obtain effective design space according to system demands. Utilizing designers＇ knowledge and expertise, it can directly determine an effective design space and provide many feasible design schemes in a few minutes.
