Document Type and Number:
Japanese Patent JP6834727
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make a plan for producing or processing products by lot units such that much more products are included in lots within practical calculation time without largely deteriorating planning accuracy.SOLUTION: In a cast organization device, an integration candidate slab group presence/absence determination part 1101 extracts integration candidate slab groups from slab groups excluded in cast pieces derived when it is determined that a convergence determination condition is satisfied by a first determination part 206 and the cast pieces. An integration candidate slab group decomposition part 1102 decomposes the integration candidate slab groups into integration candidate slabs. A second cast candidate derivation part 1104 integrates the integration candidate slabs into the cast pieces which are not turned into the integration candidate slab groups to derive cast candidates. A second optimization part 1105 derives the optimal cast candidates as the cast pieces. A second slab group redefinition part 1107 updates the cast pieces.SELECTED DRAWING: Figure 11
