Normal-boundary intersection based parametric multi-objective optimization of green sand mould system

► A novel approach that merges meta-heuristic algorithms with the Normal Boundary Intersection (NBI) method is proposed. ► This method then is used to generate optimal solution options for the green sand mould system problem in manufacturing industry. ► This NBI based method provides a near-uniform spread of the Pareto frontier in which multiple solutions with gradual trade-offs in the objectives are obtained. ► Comparative studies were then carried out with the algorithms developed and used in this paper and that from the literature. ► A holistic analysis on the performance as well as the quality of the solutions produced by the algorithms is presented in the experimental results and findings.
