Parts ordering system,parts management system and apparatus for managing ordering and reciept of orders

A parts ordering system in which a domain on a first network and a domain on a second network are connected via a public line, wherein the domain on said second network includes:

• means for receiving an order from the domain on said first network;
• means for devising a machining plan based upon the order;
• means for performing expansion, into each component part, in accordance with the machining plan;
• means for devising an ordering plan for each expanded component part;
• and
• means for ordering in units of individual parts in accordance with the ordering plan.

A parts ordering system having a database which stores a number of specific parts contained in inventory, as well as a first domain, second domain and third domain connected in a tree structure, wherein said second domain includes:

• means for performing expansion, into each component part, based upon an order received from the first domain;
• communication means for communicating, to the third domain, orders in individual parts units expanded by said expanding means;
• and
• stopping means for comparing the number of specific parts contained in inventory stored in the database and a required number of specific parts obtained by expansion performed by said expanding means, and stopping the communication of an order to the third domain in a case where the number of specific parts contained in inventory is greater, by a prescribed number, than the required number of specific parts.

A parts ordering system in which a first domain is internally provided with a database in which a number of specific parts contained in inventory has been stored, wherein said first domain includes:

• means for performing expansion, into each component part, based upon an order received from the second domain;
• communication means for communicating, to the third domain, orders in individual parts units expanded by said expanding means;
• and
• stopping means for comparing the number of specific parts contained in inventory stored in the database within the first domain and a required number of specific parts obtained by expansion performed by said expanding means, and stopping the communication of an order to the third domain in a case where the number of specific parts contained in inventory is greater, by a prescribed number, than the required number of specific parts.

A parts ordering method whereby a first domain, a second domain and a third domain connected in a tree structure deliver and receive orders via a database which stores a number of specific parts contained in inventory, comprising:

• an expanding step at which the second domain performs expansion, into each component part, based upon an order received from the first domain;
• a communication step at which the second domain communicates, to the third domain, orders in individual parts units expanded at the expanding step;
• and
• a stopping step at which the second domain compares the number of specific parts contained in inventory stored in the database and a required number of specific parts obtained by expansion performed at the expanding step, and stops the communication of an order to the third domain in a case where the number of specific parts contained in inventory is greater, by a prescribed number, than the required number of specific parts.

A parts ordering method whereby a first domain, which is internally provided with a database in which a number of specific parts contained in inventory has been stored, accepts an order from a second domain and communicates the order to a third domain, comprising:

• an expanding step at which the first domain performs expansion, into each component part, based upon an order received from the second domain;
• a communication step at which the first domain communicates, to the third domain, orders in individual parts units expanded at the expanding step;
• and
• a stopping step at which the first domain compares the number of specific parts contained in inventory stored in the database within the first domain and a required number of specific parts obtained by expansion performed at the expanding step, and stops the communication of an order to the third domain in a case where the number of specific parts contained in inventory is greater, by a prescribed number, than the required number of specific parts.

A parts management system having a database which stores a number of specific parts contained in inventory, as well as a first domain, a second domain and a third domain connected in a tree structure, wherein said second domain includes:

• means for performing expansion, into each component part, based upon an order received from the first domain;
• and
• communication means for communicating, to the third domain, orders in individual parts units expanded by said expanding means;
• said second domain having input means for inputting, to the database, information relating to a part delivered in accordance with an order.

A computer readable recording medium on which has been recorded a program by which the following means are implemented by a computer:

• means for issuing an order;
• means for receiving an order;
• means for devising a machining plan based upon the order received;
• means for performing expansion, into each component part, in accordance with the machining plan;
• means for devising an ordering plan for a part that has been expanded into its component parts;
• means for ordering a part expanded into individual parts units based upon the ordering plan;
• means for reading data from a database in accordance with the order for the part;
• and
• means for writing the read data to the database.
