A Design-Task-Oriented Model Assignment Method in Model-Based System Engineering

Figure 6

Comparison of the task set execution cycles optimized by the three algorithms, assuming equal model value summations. (a) Comparison of EC2 obtained by DA-NSGA-II and EC1 obtained by NSGA-II. Numbers 1–10 indicate the model value summations in the Pareto optimal solution set from NSGA-II of 77.3, 81.1, 84.8, 87.4, 89.6, 91.2, 93.4, 94.1, 94.9, and 95.6, respectively. (b) Comparison of EC4 determined by DA-NSGA-II and EC3 determined by PSO. Numbers 1–12 indicate the model value summations in the Pareto optimal solution set from PSO of 79.7, 81.2, 85.8, 86.1, 88.6, 89.3, 90.8, 91.4, 93.0, 94.0, 94.1, and 94.4, respectively.
