Production instruction volume decision support method and program therefor

A production instruction volume decision support method comprising the steps of:

• creating a plurality of sets of amount of the production order;
• obtaining a plurality of evaluation values based on simulation of demand for each product;
• obtaining a superiority relationship among the sets of amount of the production order from the evaluation values;
• creating a new set of amount of the production order from two sets of amount of the production order which are superior to the other sets of amount of the production order;
• repeating the above steps a predetermined number of times to obtain solutions to the plurality of sets of amount of the production order which have been optimized;
• displaying a plurality of sets of amount of the production order which have nothing superior thereto;
• and
• displaying means for enabling a user to select one of them.

A production instruction volume decision support program for enabling a computer for support decision on amount of the production order of products to function as:

• means for creating a plurality of sets of amount of the production order having information for specifying production volumes of a plurality of products;
• means for simulating demand for each product from demand forecast information of each product;
• means for computing evaluation values of a plurality of evaluation indices from demand for each product and the production volume of each product for each set of amount of the production order;
• means for computing sets of amount of the production order which are inferior to other sets of amount of the production order in some evaluation indices but superior to the other sets of amount of the production order in the other evaluation indices to output a plurality of sets of amount of the production order;
• and
• means for displaying the output plurality of sets of amount of the production order so that a user can select one of them.
