Ordered product delivery date management system for management product or part production slot exchange

摘要

When content of a production slot database indicates that there is no free production slot which can be allocated to an ordered vehicle designated in received order information, a production management section exchanges a production slot assigned to a potential vehicle so that the ordered vehicle can be delivered by the desired date. When no potential vehicle slot is available, a production slot for an ordered vehicle can be exchanged with that for another ordered vehicle for which a production slot has been secured, and the production slot date of the other vehicle is postponed to another day before the desired delivery date. When a production slot is secured before the desired delivery date but the production slot for a part required for producing the ordered vehicle cannot be secured, management of exchange is performed for the part according to a parts production slot database to enable delivery of as many vehicles by the delivery dates desired by customers as possible.
