“…These are classical methods such as mixed integer linear programming [17,18], nonlinear dynamic programming [19,20], and metaheuristic approaches such as tabu search [21], particle swarm optimization [22], bacterial foraging [23], simulated annealing [24], bee colony [25], and genetic algorithms (GA) [26,27]. Others authors [28] studied the effects of the indicators of complexity of industrial structures. In [26] the authors solved a similar problem, but their study was mainly focused on the comparison between two separation techniques rather than solving the problem directly.…”
