...Jeongwoo Han; Panos Y. Papalambros Analytical target cascading (ATC) is a multidisciplinary design optimization method for multilevel hierarchical systems. To improve computational efficiency, especially for problems under uncertainty or with strong monotonicity, a sequential linear programming...

... for each vector. Step 1. Describe the model of the hierarchical system as a combination of components shown in Fig. 5 and decide which parts should be separated. 8 Flowchart of parallel GA processes 7 Parallelization of the GA process on a divided structure This study...

... was successfully obtained, where earlier convergence was obtained for rather higher mutation ratios. Thus, it is clear that hierarchical genetic algorithms can be effectively operated. 13 Optimum individual of this numerical experiment 12 Hierarchical system of numerical experiment...
