3.20. 更便宜的时间调度
在时间和机器上调度所有任务以最大程度降低电源成本。电源价格随时间不同。这是 作业 跃点调度的一种形式。
硬限制：
- 开始时间限制：每个任务都必须在其最早的开始和最新的开始限制之间启动。
- 最大容量：不得超过每台机器的每个资源的最大容量。
- 启动和关闭：每台机器必须在已分配任务的期间内处于活动状态。在任务间，允许闲置它以避免启动和关闭成本。
中等限制：
电源成本：减少整个计划的总电源成本。
- 机器电源成本：每个活跃或空闲的机器都会消耗电源，这会降低电源成本（取决于该时的电源价格）。
- 任务电源成本：每个任务都会消耗电源，这会降低电源成本（取决于电源价格）。
- 机器启动和关闭成本：每次机器启动或关闭时，都会产生额外的成本。
软限制（在原始问题定义中添加）：
- 早期启动：首选更早启动任务，而不是稍后开始。
