Document Type and Number:

WIPO Patent Application WO/2019/077658

Kind Code:

A1

Abstract:

This transportation operation control device 40 comprises: an acquisition unit 41 that acquires presence status information 410 of an article 61; an influence degree calculation unit 42 that calculates, by employing a calculation criterion 421, the magnitude of the degree of influence on a transportation start site 51 by a pre-process site 53 that influences the transportation start site 51 on the basis of the presence status information 410 related to the transportation start site 51 and the pre-process site 53; an importance degree calculation unit 43 that calculates the degree of importance 431 of a transportation operation from the transportation start site 51 to a transportation destination site 52 on the basis of a transportation cost 430 required for the transportation operation, the presence status information 410, and the magnitude of the degree of influence 420; and an updating unit 44 that updates the calculation criterion 421 on the basis of the presence status information 410 after the execution of the transportation operation selected on the basis of the degree of importance 431. Thus, in a factory etc. in which transportation capability and the load on operation processes fluctuate, it is possible to reliably execute article transportation control for avoiding a reduction in processing efficiency of the entire factory caused by a downstream process being influenced by fluctuations in an upstream process.
