Alzahrani %J American Journal of Industrial Engineering %D 2019 %R 10.12691/ajie-6-1-1 %X In this study, a multi-objective job-shop scheduling model is developed to optimize makespan, maximum job tardiness and maximum and idle time of machines under risk. The model considers multi-jobs and multi-machines. Each task has a specific due date and random processing times of specific probability distribution. The model is solved using @RiskOptimizer %U http://www.sciepub.com/AJIE/abstract/10968
