Abstract

The present application relates to a technique of calculating an environmental load amount of each product produced on a production line including types of processing apparatuses. Power consumption required for producing a product is obtained more accurately and in an earlier stage. Power consumption required for producing each product is obtained by using the power consumption for each product with respect to each apparatus.
