A new multi-objective multi-mode model for solving preemptive timecostquality trade-off project scheduling problems
Considering timecostquality trade-offs in project scheduling is an important problem. A customized, dynamic and self-adaptive NSGA-II is proposed to solve these problems. We consider preemption and generalized precedence relations. The proposed NSGA-II is compared with an efficient ?-constraint method. The results show the relative dominance of our NSGA-II over the ?-constraint method.
