Modeling of an Optimal Outbound Logistics System (A Contemporary Review Study on effects of Vehicle Routing, Facility Location and Locational Routing Problems)

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 MultiDepot (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.
