Red Hat Summit3.20. コストを抑えるスケジュール
全タスクを時間内にスケジュールし、機械の電気代を最小限に抑えます。電気代は時間によって異なります。これは、ジョブショップスケジューリング の応用です。
ハード制約:
- 開始時間の制限: 各タスクは、最早と最遅の開始時間の制限内に、開始する必要がある。
- 最大容量: マシンに割り当てる各リソースはこの量を超えてはいけない。
- 開始および終了: 各機械は、タスクが割り当てられている間は稼働している必要がある。次のタスクまでの間、起動および終了コストを避けるため、機械をアイドルにすることができる。
中程度の制約:
電気代: 全スケジュールの合計電気代を最小限に抑える。
- 機械の電気代: 稼働中またはアイドル中の機械はそれぞれ、電気を消費し、電気代が発生する (金額は使用時の電気代によって異なる)。
- タスクの電気代: 各タスクも電気を消費し、電気代が発生する (金額は使用時の電気代によって異なる)。
- 機械の起動および終了コスト: 機械を起動または終了するたびに、追加のコストが発生する。
ソフト制約 (問題に元々設定されている定義に追加):
- 早く開始: なるべく早めにタスクを開始するようにする。
この問題は、ICON challenge で定義されています。
