A manufacturing management system capable of appropriately evaluating a degree of consumption of each component of a manufacturing machine, and efficiently operating a manufacturing cell including the manufacturing machines. A control unit of a cell controller has: a manufacturing machine information receiving part configured to receive manufacturing machine information regarding an operational history of each component constituting the manufacturing machine; a component degree of consumption calculating part configured to calculate a weighed degree of consumption of each component, based on the manufacturing machine information and a predetermined weight of each component; a manufacturing machine degree of consumption calculating part configured to calculate a degree of consumption of each manufacturing machine, based on the weighed degree of consumption of each component; and a manufacturing machine selecting part configured to select a manufacturing machine to be used in the manufacturing cell, based on the degree of consumption of each manufacturing machine.
