Development of Simulation System For Real-Time Location Tracking In Global Shipping Logistics

Abstract

In global shipping logistics, it is important for users to keep track of the location of their continuously moving cargos. Analyzing the GPS data stream coming from the tag which is attached to the cargo, we are able to keep track of the cargo location in terms of going into or out of a certain logistics area using the information of the spatial relationship change between the tag and the logistics area. In this paper, we propose a simulation system for measuring the precision and false alarm rate of the cargo location tracking algorithm which generates spatial events over the global logistics areas. Due to the difficulty of experiment with a real tag, we developed a tag emulator to create a virtual tag which operates exactly like a real tag. We show the cargo location tracking system works correctly with the tag emulator which communicates with it using the same protocol as the real tag.

A Study on IoT-based Fleet Maintenance Management

“…Therefore, tag information cannot be read without an RFID reader or recognized when a metal material exists between a tag and a reader [26]. In contrast to the RFID technology, the IoT technology can obtain information in real-time through real-time network communication [9][10][11].…”

“…As this technology can solve a problem related to the limitations of radio-frequency identification (RFID), a communication module can be equipped to the IoT equipment to facilitate real-time network communication [9][10][11]. The application of the IoT technology can combine information and minimize the gap between the flow of distribution and information, thereby leading to effective supply chain management [12].…”

A Study on Vehicle Routing Problems Considering IoT based Real Time Information

“…If applying the IoT technology that generates data in real time, effective management can be achieved with not only information integration but also minimization of the gap of information flow [1]. The IoT based real time information ensures traceability and visibility of product that can reduce logistics cost and promote customer confidence [2].…”
