To manage pick-up and delivery operations more effectively, geographical information system (GIS), global positioning system (GPS), and wireless communication technologies are applied to the system which consists of three subsystems, pick-up and delivery sequence planning system, pick-up and delivery monitoring system, and PDA execution system. Pick-up and delivery sequence planning system generates routes and schedules for pick-up and delivery using GIS and optimization techniques. Pick-up and delivery monitoring system monitors current positions of vehicles and actual pick-up and delivery results as compared with planned sequences, routes and visit times, while PDA execution system transmits information for vehicles positions and actual pick-up and delivery results using GPS and wireless communication technologies. The intelligent monitoring and control system is currently being used for the pick-up service in a local post office of Korea Post.
