Abstract

This control system comprises: a memory device which memorizes therein storage information that includes information about articles stored in a mobile rack used to store such articles and storage positions of said articles; and an arithmetic device which controls traveling of a conveyance apparatus for mounting thereon and conveying the mobile rack. The arithmetic device calculates characteristics concerning the weight distribution of the mobile rack on the basis of the storage information, and determines a travel condition that includes the speed and / or acceleration of the conveyance apparatus, on the basis of the characteristics concerning the weight distribution.
