Abstract
In this study, the Grey Wolf Optimizer (GWO) algorithm is effectively employed to optimally schedule an urban metro system. The primary objective of this research is to significantly minimize the total passenger travel time, including waiting time at stations and in-train travel time. The proposed model considers parameters such as passenger arrival rates, stop durations, and the optimization variable h to simultaneously optimize departure and stop times. The implementation results on real-world data indicate that the cost function is significantly reduced from 23,500.75 seconds to 16,939.12 seconds using this approach. Additionally, the reduction in waiting time at high-traffic stations leads to a substantial improvement in system efficiency and passenger satisfaction. This innovative approach can pave the way for developing intelligent solutions in public transportation systems, reducing operational costs, and enhancing metro system performance. The results obtained open new avenues for future research aimed at further improving metro scheduling and management.
