Abstract
Efficient location-routing planning is critical for disaster relief operations, where timely decisions significantly impact emergency response effectiveness. This study proposes three different models, each building upon the previous one, with the aim of minimizing total costs.
In the first model, a single-objective LRP assigns each affected area to only one shelter and determines the minimum number of vehicles required under a time constraint. The second model extends the first by allowing vehicles to serve multiple affected areas from the same shelter if needed, improving resource utilization and cost efficiency. The third model introduces more realistic conditions, including heterogeneous vehicles and different types of shelters with capacity selection options, reflecting real-world complexities. This framework balances computational efficiency with practical usability, demonstrating its potential to optimize shelter selection and vehicle allocation, thereby improving disaster response efficiency. By addressing real-world constraints and complexities, this study provides a practical decision-support tool for emergency decision-makers.
