Abstract
The present invention increases the productivity of an entire factory, even of the type that produces different types of products in different quantities using transport vehicles, by performing transport operation control. This transport operation control device is provided with: a spatial distribution measuring unit which measures the spatial distribution of products-in-process being transported by the transport vehicles; and an operation schedule calculation unit which, on the basis of the measured spatial distribution of the group of partly-finished products, calculates an operation schedule that specifies both a route and a frequency of a transport operation to be carried out by each transport vehicle of the transport vehicles, wherein the operation schedule calculation unit determines the timing with which to update the operation schedule, on the basis of changes in a productivity index that is determined from the measured spatial distribution of the products-in-process.
