When the operation of any of manufacturing apparatus is halted, influence exerted by the operation halt on the manufacturing state of each of products is evaluated based on the difference between the number of products in a processing waiting state in the manufacturing apparatus at a time at which the operation of the manufacturing apparatus is halted or at a time antecedent thereto and the number of products in the processing waiting state in the manufacturing apparatus at a time at which the manufacturing apparatus is reoperated after the operation thereof is halted or at a time posterior thereto or on the difference between the period during which the product processed by the manufacturing apparatus during a given period antecedent to the time at which the operation of the manufacturing apparatus is halted is in the processing waiting state in the manufacturing apparatus and the period during which the product processed by the manufacturing apparatus during the given period posterior to the time at which the manufacturing apparatus is reoperated after the operation thereof is halted is in the processing waiting state in the manufacturing apparatus.
