Abstract
Description
本発明は、厚板製品の出鋼チャージ数決定支援装置に関する。 The present invention relates to an apparatus for determining the number of outgoing steel charges for a thick plate product.
鉄鋼厚板製品の製造総コストは、（１）製鋼コスト（合金量、鋼種名、モールド制約、連々鋳）、（２）圧延コスト（圧延能率：ｔｏｎ/ｈｒ）、（３）熱処理コスト（￥/ｔｏｎ）はもとより、社会情勢やミル稼動状況、受注状況（製造仕様/納期）に左右されるから、これらを勘案して製造総コストが最小になる最適製造仕様の設定が指向される。
完全受注生産の厚板品種では、上記観点（（１）〜（３））からの製造総コストの低減の為、通常、ロット拡大による製鋼コストの低減を最優先し、注文（製品仕様）と一対一の関係にある製造仕様のうち、特に鋼種集約やモールド集約による連々鋳アップにてコスト低減を図っている（例えば特許文献１参照）。その為、汎用鋼種での製造仕様設定が指向されている。
The total production cost of steel plate products is as follows: (1) Steelmaking cost (alloy amount, steel type name, mold restriction, continuous casting), (2) rolling cost (rolling efficiency: ton / hr), (3) heat treatment cost (¥ / ton), as well as the social situation, mill operation status, and order status (manufacturing specifications / delivery date), the optimum manufacturing specifications that minimize the total manufacturing cost are aimed at considering these factors.
In order to reduce the total manufacturing cost from the above viewpoints ((1) to (3)), ordering (product specifications) Among manufacturing specifications having a one-to-one relationship, cost reduction is achieved by continuous casting up by steel type consolidation or mold consolidation (see, for example, Patent Document 1). Therefore, the production specification setting for general-purpose steel grades is directed.
然し、製品仕様と製造仕様とが一対一に設定されている事で、製鋼での出鋼量の基本単位（標準出鋼単位という）例えば２５０トンに対し、例えば２８０トンのオーダ（注文）があったとすると、このオーダに対応する製品仕様の鋼種の出鋼枠は、２５０トン×２チャージ＝５００トンとされるが、オーダ分の２８０トンを除いた残りの２２０トンは充当先が見つかるまでストックされ、結果的に充当先が見つからなかった分は屑とされる。
つまり、従来では、製品仕様と製造仕様とが一対一に設定されている為に、注文品に係る鋼種である上位鋼種の必要出鋼量を満たす為の出鋼枠を製鋼出鋼単位で割った余りの出鋼品は、注文待ち品となって在庫負担が増すという課題があった。
However, since the product specification and the production specification are set one-to-one, the basic unit of steel output in steelmaking (referred to as standard steel output unit), for example, 250 tons, for example, an order (order) of 280 tons, for example. Assuming that there is a steel frame of the product specification corresponding to this order, 250 tons x 2 charges = 500 tons, but the remaining 220 tons excluding 280 tons for the order will be found until the appropriation destination is found. The part that is stocked and as a result the destination is not found is regarded as scrap.
In other words, in the past, product specifications and production specifications are set on a one-to-one basis, so the steel output frame to satisfy the required steel output of the upper steel grade, which is the steel type related to the ordered product, is divided by the steelmaking steel output unit. There was a problem that excess steel products were waiting for orders and increased the stock burden.
発明者らは前記課題を解決するために検討し、その結果、上位鋼種（合金成分コストが相対的に高い鋼種）の出鋼枠を埋める為に、標準では下位鋼種（合金成分コストが相対的に低い鋼種）を適用するオーダについて上位鋼種の適用が可能であるものを探して引き当てるという手法に想到し、本発明を成した。
即ち本発明は次のとおりである。
（１） 総注文情報データベース（DB1）から総注文情報を読み込む読み込み部(10)と、該読み込みの結果に基き製品仕様データベース(DB2)から各注文品への製品仕様を引き当てる第１の検索部20と、該引き当ての結果に基き製造仕様データベース(DB3)から各製品仕様への標準製造仕様を引き当てて仮製造仕様として決定する第２の検索部(30)とを有する仮製造仕様の決定手段(1)、並びに、
前記決定の結果に基き前記各注文品の仮製造仕様中の鋼種である仮決定鋼種の必要出鋼量合計値を計算する必要出鋼量計算部(40)と、該計算の結果と標準出鋼単位とを用いて出鋼可否を判定する第１の出鋼可否判定部（50）と、該判定の結果に基き、前記各データベース(DB1, DB2, DB3）を参照して、仮決定鋼種よりも下位の鋼種を標準製造仕様としているが仮決定鋼種での代替製造仕様も可とされた注文品である上位鋼種運用候補注文品に係る鋼種である代替鋼種の有無を調べる第３の検索部(60)と、該調べた結果に基き、前記代替鋼種について前記と同様の必要出鋼量合計値の計算乃至出鋼可否の判定を行うか或いは例外処理判断を行う第２の出鋼可否判定部(70)とを有する鋼種毎の必要出鋼量の調整手段(2)、

Manufacturing specification database DB3 is manufacturing conditions to realize product specifications, such as steel grade, required steel output (> shipment weight of ordered products), manufacturing conditions (conditions for heating, rolling, cooling, heat treatment, etc.), inspection The storage means stores a set of manufacturing specifications including elements such as conditions and packing specifications. One product specification is associated with one or more manufacturing specifications. When a plurality of manufacturing specifications correspond to one product specification, the plurality of manufacturing specifications are given priority. The highest-priority manufacturing specification is the standard manufacturing specification, and the other manufacturing specifications are the alternative manufacturing specifications.
