1. A casting facility control system controlling a casting facility, the casting facility including a molding machine, a mold conveyance device, a melting furnace, a ladle transportation device, and a pouring machine, the molding machine molding a plurality of molds, the mold conveyance device arranging in a line and conveying the plurality of molds molded by the molding machine, the melting furnace melting material to be melted, the ladle transportation device transporting a ladle, the pouring machine pouring molten metal in the ladle transported by the ladle transportation device into the plurality of molds conveyed by the mold conveyance device, the casting facility control system comprising:
a database configured to store a plurality of conveyance positions fixedly assigned to the line of molds, and mold information corresponding to a mold positioned at each of the conveyance positions in association with each other;
an update section configured to update the mold information associated with each of the conveyance positions stored in the database, in response to flask feeding by the mold conveyance device;
a measurement section configured to measure a weight of the molten metal in the ladle transported to the pouring machine by the ladle transportation device;
a calculation section configured to calculate a number of flasks by which the molten metal poured from the ladle transported to the pouring machine can be held, based on the weight of the molten metal measured by the measurement section and on a planned weight of molten metal included in the mold information associated with each of the conveyance positions stored in the database;
a decision section configured to recognize, based on the number of flasks by which the poured molten metal can be held calculated by the calculation section, the plurality of molds into which the molten metal to be next transported to the pouring machine is poured, add up the planned weight of molten metal corresponding to each of the recognized molds, and determine a predicted weight of molten metal to be next transported to the pouring machine; and
an output section configured to output the predicted weight determined by the decision section, as fabrication instruction data on the melting furnace.

20. A casting facility control system controlling a casting facility, the casting facility including a molding machine, a mold conveyance device, a melting furnace, a ladle transportation device, and a pouring machine, the molding machine molding a plurality of molds, the mold conveyance device arranging in a line and conveying the plurality of molds molded by the molding machine, the melting furnace melting material to be melted, the ladle transportation device transporting a ladle, the pouring machine pouring molten metal in the ladle transported by the ladle transportation device into the plurality of molds conveyed by the mold conveyance device, the casting facility control system comprising:
a measurement section configured to measure a weight of the molten metal in the ladle transported to the pouring machine by the ladle transportation device; and
a decision section configured to determine a weight of molten metal to be next transported to the pouring machine,
wherein the weight of the molten metal to be next transported to the pouring machine is equal to a weight obtained by adding up planned weights of molten metal corresponding to the plurality of molds, the plurality of molds being determined depending on a number of flasks by which the poured molten metal can be held calculated based on the weight of the molten metal in the ladle measured by the measurement section and on a planned weight of molten metal associated with each conveyance position.
