Most public health supply chains use static routes for the distribution of health commodities. While many countries have conducted one-time optimization exercises to make their static routes more efficient and cost-effective. Still, these one-time optimized routes are reused each distribution cycle, making it difficult to adapt to ever-changing circumstances. Dispatch Optimizer Tool (DOT) provides a user-friendly interface for loading data to optimize delivery routes for public health commodities to the last mile based on dynamic, changing conditions and order volumes. It is built using open-source software and web hosted; the source code is available on GitHub for future use.
