Development of Continuous Scanning for Fixed Type Container X-Ray Inspection System

Abstract

This study aims to develop a fixed type container inspection system (CIS) which is possible to scan continuously in order to enhance the efficiency of the system. The scanning time lagging due to standby time of vehicles is strongly related to the efficiency of the CIS, It is necessary to develop the continuous scanning fixed type CIS because the operation efficiency is proportional to the number of CIS sites and construction cost. Thus the continuous scanning fixed type CIS is designed and verified with ARENA simulation tool in order to enhance the whole operation time of the existing CIS. The parameters applied for the simulation are the times caused by building size, shielding door, vehicle transport system, and driver. As the result of the simulation, the extension of the Vehicle Transport System (VTS) rails in order to circle the VTS and 4 VTSs are required to realize the continuous scanning and the system is currently under construction.
