Abstract
Layout design of highly packed equipments is under not only its geometric conditions but also its physical conditions, such as radiation characteristic, structural strength, electromagnetic shielding. Its characteristic shares some concepts with the paradigm of multidisciplinary design optimization (MDO). However, applicability of MDO is still natively limited within continuous optimization problems. This paper proposes a basic idea for optimization-based layout design approaches, in which layout space is minimized and radiation characteristic is optimized simultaneously. In the approach, the layout topology is represented with sequence quintuple and optimized with simulated annealing (SA), while radiation characteristic is evaluated by thermal network method concurrently at the arranged stages in the double loop of the developed SA algorithm. The relationship between concurrency of evaluation and solution quality is discussed with numerical experiments.
