Railways, a vast and complex transportation network, faced significant challenges in managing crew scheduling. Manual processes often resulted in suboptimal allocations, leading to increased costs, reduced efficiency, and decreased employee satisfaction. To address these issues, we sought to optimize crew scheduling and allocation, minimizing crew strength while improving the overall quality of life for the crew. By leveraging advanced optimization techniques, we aimed to enhance operational efficiency, reduce costs, and ensure a more equitable distribution of work among crew members.

To address the challenges faced by railways in manual crew scheduling, a Mixed Integer Programming (MIP) model was developed. This model incorporated several key constraints to ensure that the optimized schedules were feasible and aligned with operational requirements.
First, the model ensured that all scheduled routes were covered, preventing disruptions to the railway's operations. Second, it adhered to strict labor union rules and regulations, ensuring compliance with industry standards and maintaining positive relationships with employees. Third, the model considered crew repositioning at base stations, minimizing unnecessary travel time and improving crew efficiency.
The implementation of the MIP model involved several steps. Historical data on crew schedules, operational data, and labor union rules were collected and analyzed to gain a comprehensive understanding of the existing system. This data was then used to formulate the MIP model, defining the objective function (minimizing crew strength) and constraints. The model was validated and tested using historical data to ensure its effectiveness.

A Mixed Integer Programming (MIP) model was developed and solved using IBM ILOG CPLEX to optimize crew scheduling and allocation.
To achieve an optimal crew scheduling solution, several constraints were considered. These constraints ensured that the solution was feasible, practical, and aligned with operational requirements.
For example, the requirement to cover all scheduled routes ensured uninterrupted railway services. Adherence to labor union rules and regulations protected the rights of crew members and maintained harmonious relationships with labor unions. Finally, considering crew repositioning at base stations helped optimize resource allocation and reduce unnecessary travel time for crew members, contributing to their overall well-being and job satisfaction.
These constraints played a critical role in balancing the competing objectives of minimizing crew strength while maximizing employee satisfaction and operational efficiency.
