Scheduling is a crucial factor in engineering, project, and production management (Pinedo, 2012). Huang et al. applied Ant Colony Optimization (ACO) to develop a resource constraints scheduling model. ACO is frequently used to solve optimization problems (Chandra Mohan and Baskaran, 2012). In the paper, resource constraints are formulated using mathematical equations and optimized using ACO. International test bank data are then used to verify the effectiveness of the proposed model, which provides satisfactory performance with reasonable computational times.
