<p><P>PROBLEM TO BE SOLVED: To provide a division planning technique satisfying piling-up constraints, optimizing work efficiency of conveying/carrying equipment etc. used to handle steel materials and enhancing productivity as a steel yard, in preparing division planning for the steel materials in the steel yard to pile up the steel materials and manage the storage site thereof. <P>SOLUTION: An optimal steel material division planning device 2 receives target steel materials to be managed and their attributes 11 from a steel material management device 1; sequentially generates subsets of a target steel material set 10 by an all subset generating part 3; and extracts a subset satisfying the piling-up constraints preset by a piling-up constraint set part 17 from the all subset generating part 3 by a piling-up constraint acceptability determining part 4, as a realizable pile set 12. Based on this, a set division constraint expression 13 is generated by a set division constraint generating part 5, and an evaluation function 14 is generated by an evaluation function setting part 6. In accordance with the both expressions, an optimal division result (division planning) 15 is calculated and output by an optimal solution calculating part 7. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
