Abstract

Transportation is one of the key areas in supply chain management. Emergency vehicles, firefighters, and ambulances are one of the priorities needed in densely populated settlements to reduce casualties from an incident. This study aims to map VRP research by considering under-deadline conditions and provide an overview of current trends and positions for future research. A systematic literature review is necessary to connect studies, investigations, and decision-making. It can be validated with databases that need to be reviewed using a systematic search including research questions, methodology, and specific exclusion and inclusion criteria. Based on the results of the analysis that has been carried out, the results of the most suitable journals were published in Applied Soft Computing, Procedia Computer Science, Computers & Industrial Engineering, and Transportation Research Part E. The most frequently used method is the Exact Algorithm. Eight types of variables are included in the existing discussion.
