Abstract

Power consumption required for producing a product is obtained more accurately and in an earlier stage.

Actual line power consumption of a production line, apparatus characteristics of each apparatus of the production line, a rated power of each apparatus, and numerical data of each specification item of each product are received (S31). A coefficient for each apparatus is determined by using a relation between an apparatus characteristic and a ratio (coefficient) of the actual power consumption to the rated power of the apparatus (S32). A correlated specification item for each apparatus is determined by using an apparatus characteristic-correlated specification item relation that relates an apparatus characteristic and a specification item correlated with the apparatus power consumption (S33). Power consumption of each apparatus is obtained by allotting the actual line power consumption to each apparatus by using the rated power and coefficient of each apparatus (S34). Power consumption for each product with respect to each apparatus is obtained by allotting the power consumption of each apparatus to each product by using the numerical data of the correlated specification item for each apparatus (S35). And, power consumption required for producing each product is obtained by using the power consumption for each product with respect to each apparatus (S36).
