Multi-objective optimal scheduling of automated construction equipment using non-dominated sorting genetic algorithm (NSGA-III)

Unstructured and variable construction sites bring challenges that can be addressed with the adoption of the flexible earthwork scheduling problem (FESP), which requires consideration of mechanical parameters, automated construction techniques, and site constraints. This paper describes the use of the non-dominated sorting genetic algorithm (NSGA-III) for such problems, yielding better results than the NSGA-II and strength pareto evolutionary algorithm (SPEA). This method produces a set of Pareto-optimal results for each case study, which are then ranked by the analytic hierarchy process (AHP) method to determine an optimal scheduling scheme. The results help project managers and dispatchers by automating the schedule process and by graphically analyzing the solutions”.
