Abstract:
In recent years, problems related to warehouse management has become an important consent in
the field of logistics management research and has been widely used in analyzing through transportation and
logistics distribution systems. This paper aims to conduct a comprehensive literature review on recent model
developments and improvements involving Vehicle Routing Problem(VRP), Facility Location Problems and
Location Routing Problems along with its variants. VRP is a widely studied combinatorial optimization
problem in operational research and computer science. The VRP is categorized by Capacitated Vehicle Routing
Problem (CVRP), Vehicle Routing Problem with Time Windows (VRPTW), Vehicle Routing Problem with Multi-
Depot (MDVRP) and their variants. Further discussions has been carried on in the areas of classification of
VRP, summarization of the common constraints of VRP, model algorithm developed in recent years. Finally, it
is being analyzed, the future model implications of VRP, and it is considered that the Intelligent Vehicle Routing
Problem and Intelligent Heuristic Algorithm will be an important field of future research.The review study also
aims at finding the effect and developments in Facility Location Problems which are classical optimization
problems having an extensive application in transportation, distribution, production and supply chain
management decisions.This will also provide a broader overview of Location Routing Problems, indicating how
they are formulated and what are the proposed solutions.
