The Expansions of Vehicle Routing Problems: A Logistical Overview

This paper provides an overview of the expansions ofVRP (vehicle routing problems) from a logistical point of view. The expansion includes the integration between VRP and inventory problems. That integration is known as IRP (inventory-routing problems). Another expansion is the integration of VRP with location problems which is then known as LRP (location-routing problems). The last expansion is known as LIRP (location-inventory-routing problems) which is the integration between VRP, inventory problems, and location problems. This paper also provides suggestions for future research related to the expansion of VRP.
