MADE-TO-ORDER PRODUCTION METHOD, DATA PROCESSING METHOD AND SYSTEM, DEALER TERMINAL DEVICE AND INFORMATION STORAGE MEDIUM

PROBLEM TO BE SOLVED: To make it possible to produce a custom product even though a part of components of a repeatedly ordered product configuration does not exist in a system for generating the product configuration from the request specifica tion of an ordering user to produce the custom product, performing data registra tion of the once generated product configuration together with identification data and utilizing the product configuration for its repeated order. SOLUTION: A producer can easily, quickly and repeatedly produce the custom product of the same specification without having to make the ordering user prepare a request specification again because of restoring the data of the request specification from the product configuration to newly generate the data of the product configuration even in the case a part of the components of the product configuration whose data are read with the identification data subjected to the repeated order is not in existence now.
