When the user wants to model or solve flow-shop scheduling problems - permutation flow-shop makespan computation, the NEH heuristic, MIP models in gurobipy, and iterated greedy as the state-of-the-art metaheuristic, with a makespan-plus-tardiness multi-objective extension. Also use when the user mentions "flow shop," "permutation flow shop," "NEH," "iterated greedy," "Taillard," "makespan minimization," or when every job visits all machines in the same fixed order. For job-specific machine routes, see job-shop-scheduling; for Pareto trade-off analysis, see multi-objective-optimization.
