The purpose of this book is to introduce a systematic method for the integrated layout design of the components packing and structural patterns of the multi-component systems. In view of the common design requirements of aerospace structural systems, the integrated design is studied as a simultaneous optimization procedure in this work. The method of FCM is firstly developed to solve the packing problems. Using certain numbers of circum- circles to describe the contour of the components and the design domain approximately, the complex geometry constraints are transformed into some ...
