A position information acquiring apparatus for receiving an electric wave and for on the basis of the received signal, acquiring the position information exhibiting the position where the product is kept to record successively the position information thus acquired is packed together with an objective matter of conveyance in a package box and then is operated in the state of being able to be moved to receive an electric wave signal radiated from the GPS satellite group to acquire successively the position information. On the basis of the position information, a map of a part corresponding to the position information is retrieved from map information which is previously obtained to carry out an output for showing visibly the resultant partial map and a symbol with which the position contained in a position history information is shown on the map.

Method of collecting information of physical distribution of products and system for offering information of product positions

A product configuration is managed on a product basis for each of component parts included in products from manufacturing to disposal of the products. A product manufacturer device, part manufacturer devices, and a device of a customer who possesses a product are interconnected through a communication line. The product manufacturer device includes configuration information on each of component parts in the product on a product number basis, and provides information and services on the product. The part manufacturer device includes configuration information on each of lower parts which include the component parts on a manufacturing lot or product number basis, and provides information and services on each of the parts. When the product configuration is changed, such change is reflected to the configuration information of the product and the component parts.

Product management method and system

In the fabrication of an electronic circuit such as an integrated circuit, a method of determining the arrangement of logic circuit devices on a circuit board on the basis of a logic data defining the logic circuit devices and the interconnections among them. The logic circuit devices are classified in groups in accordance with a degree that each signal line connected with the logic circuit devices requires the expedition of signal propagation therethrough. First, the logic circuit devices belonging to the group pertinent to the highest degree are arranged, and next those belonging to the group pertinent to the second highest degree are arranged. Such a processing is carried out for all the groups.
