For the objectives of minimizing the total weighted tardiness of orders and the schedule deviation of Robustness the realized schedule from the baseline schedule, two surrogate measures for each of the two objectives are Single machine proposed to cope with the processing time uncertainty in the baseline scheduling phase. For the suggested Multi-level product structure surrogate measures, several optimal solution properties are developed to reduce the size of the solution space. Particle swarm optimization Then, by using the solution properties a heuristic algorithm with two diﬀerent order prioritization rules and a metaheuristic algorithm based on the discrete particle swarm optimization are developed for the order
