“…The number of production problems can be solved using various methods such as mathematical and the heuristic method. Several methods can be applied in determining the number of production, among others: ant colony algorithm (Qamhan et al, 2020;Wu et al, 2012;Zhang et al, 2020) and PSO (Chakrabortty et al, 2015). Fuzzy linear programming (Vasant et al, 2004), Fuzzy TOPSIS and goal programming (Khemiri et al, 2017), variable neighborhood search (Almada-Lobo et al, 2008), simulated annealing (Baxendale et al, 2021;Tung et al, 2016), and genetic algorithm (Fahimnia et al, 2012;Ramezanian et al, 2012;Yuliastuti et al, 2019).…”
