1. An environmental load amount calculation program that calculates an amount of an environmental load of each of kinds of products produced in an object production line that comprises kinds of processing apparatuses, wherein the environmental load amount calculation program makes a computer execute:

  • a first relation acquisition step, in which, for each of kinds of processing apparatus characteristics, an apparatus characteristic-coefficient relation that indicates a relation between the processing apparatus characteristic in question and a coefficient indicating a ratio of an actual environmental load to a rated value of environmental load of a processing apparatus is acquired and stored in a storage unit of the computer;

    a second relation acquisition step, in which, for each of the kinds of processing apparatus characteristics, an apparatus characteristic-correlated specification item relation that relates the processing apparatus characteristic in question and a specification item having prescribed correlation with an amount of an environmental load of a processing apparatus among a plurality of product specification items is acquired and stored in the storage unit;

    a receiving step, in which a receiving means of the computer receives;

    an amount of a line environmental load as an actual amount of an environmental load for a prescribed period in the object production line;

    processing apparatus characteristics of each of the kinds of processing apparatuses constituting the object production line;

    a rated value of environmental load of each of the kinds of processing apparatuses constituting the object production line; and

    numerical data of each specification item for each of the kinds of products produced in the object production line;

    a coefficient setting step, in which, for each of the kinds of processing apparatuses constituting the object production line, the apparatus characteristic-coefficient relation (which is stored in the storing unit) for each of the kinds of processing characteristics is used to determine a coefficient corresponding to the apparatus characteristic (which is received in the receiving step) of the processing apparatus;

    a line load allotting step, in which the line environmental load received in the receiving step is allotted to each processing apparatus by using the rated value of environmental load and the coefficient for each of the kinds of processing apparatuses constituting the object production line, in order to obtain an apparatus load of each processing apparatus;

    a correlated specification item setting step, in which, for each of the kinds of processing apparatuses constituting the object production line, a product correlated specification item corresponding to the apparatus characteristic (which is received in the receiving step) of the processing apparatus is determined by using the apparatus characteristic-correlated specification item relation (which is stored in the storage unit) for each of the kinds of processing apparatuses;

    an apparatus load allotting step, in which, by using numerical data of each product concerning the correlated specification item determined for each of the kinds of processing apparatuses constituting the object production line among the numerical data (which are received in the receiving step) of the specification items of each of the kinds of products, the apparatus load (which is obtained in the line load allotting step) for each processing apparatus is allotted to each product on a basis of correlation between the numerical data of each product and an apparatus load required for processing that product, in order to obtain a product load for each product and for each of the kinds of processing apparatus; and

    a production environmental load amount calculation step, in which the product load obtained in the apparatus load allotting step for each apparatus and for each product is used to obtain an amount of a production environmental load required for producing a product in the object production line for each product, and the obtained production environmental load amount for each product is stored in the storage unit.
