System for controlling physical distribution pallets
First Claim
1. A system for controlling physical distribution pallets used for transportation of freight in wide area physical distribution, comprising:
- a wireless tag mounted on each pallet,said wireless tag storing pallet control information of the pallet and operable for transmitting said pallet control information in wireless by radio wave energy which is generated in said wireless tag;
wireless detecting means installed at each of a plurality of physical distribution bases for detecting pallet control information transmitted from the wireless tag mounted on each pallet arriving at or departing from a respective physical distribution base;
stock data storage means for receiving and storing the pallet control information detected by said wireless detecting means via a wide area communication network;
pallet status judging means for judging whether a pallet stored in said pallet stock data storage means is empty or not based on the pallet control information of said pallet;
transport schedule storage means for storing information relating to a schedule of transport services and supply; and
demand predicting means for predicting supply and demand of pallets at said physical distribution base according to the information stored in said transport schedule storage means and according to a quantity of pallets in an empty status at the physical distribution base,further comprising forwarding plan setting means for setting up a pallet forwarding plan between the physical distribution bases according to the predicted supply and demand data of pallets obtained by said supply and demand predicting means and knowledge or constraint condition relating to supply and demand of pallets.

Abstract
The present invention provides a system for controlling physical distribution pallets, by which it is possible to accurately identify status of pallets, to set up an adequate forwarding plan of pallets, and to accomplish physical distribution in smooth manner. The system comprises wireless detecting means 22 mounted on pallets and for detecting pallet control information transmitted from transmitting means 21 which stores pallet control information of said pallet and transmits in wireless, pallet stock data storage means 23 for receiving and storing the pallet control information detected by the wireless detecting means via a wide area communication network, and pallet status judging means 24 for judging whether the pallet stored in memory of the pallet stock data storage means is empty or not based on the pallet control information of said pallet. Further, it comprises supply and demand predicting means 27 for predicting supply and demand of pallets at physical distribution bases and planning means 29 for setting up a forwarding plan for forwarding pallets at minimal cost between physical distribution bases. It is possible according to the present system to accurately identify the status of pallets, to set up an adequate forwarding plan for pallets, and to accomplish smooth physical distribution.

6. A system for controlling physical distribution pallets for controlling a stock of pallets and for setting up a pallet forwarding plan in wide area physical distribution comprising:
-
a user interface for accepting request of a user and for displaying the pallet forwarding plan thus set up; a wireless tag device for automatically acquiring information relating to entry or departure of pallets to or from stock, said wireless tag device operable for transmitting said information in wireless by radio wave energy which is generated in said wireless tag device; accumulating means for accumulating information of acquired pallets or information of the pallet forwarding plan thus set up; and a system main unit for reading information of said accumulating means and for setting up the pallet forwarding plan requested by the user, wherein said system main unit comprises hierarchical planning means for dividing physical distribution bases into bases between districts and bases within a district and hierarchically setting up said pallet forwarding plan into a plan between districts and a plan within a district.
