An interbay transportation system includes bays in which process equipment are provided, stockers provided for the individual bays, and a vehicle traveling through the stockers for transporting a semi-processed product from one of the stockers to another. Timing to start transportation is determined according to the operation status of the process equipment and the number of semi-processed products in the stocker.

Method of interbay transportation

A transportation system includes lifts for inter-floor carriage, a carrier cart for intra-floor carriage, and a transit stocker for loading/unloading an article to/from the lift. For each of the lifts, operation status, that is, operating or not, is recorded in a database. The operating rate of each lift, carriage queue for each lift, and an inventory of each transit stocker might also be recorded in the database. When carriage of an article is required, a lift optimum for the carriage is selected from among the lifts based on the information recorded on the database.
