摘要：
Production tasks are scheduled to optimize production constraints while taking time varying energy prices into account. An energy management layer (EML) is in communication with a manufacturing domain as well as a smart grid domain. The EML receives information relating to a factory workflow, costs associated with operating units within the factory, and static utility information such as tariff models and incentives. Time variant energy price information is obtained from a utility regarding periodic price levels for a near future timeframe. The workflow is converted to a matrix representation that is acceptable to a mixed integer linear programming (MILP) solver. An algebraic factor representing a tradeoff between energy cost and full-capacity production is minimized to produce production variables which control production and limit production units and tasks to be performed during time slots that are most economically favorable.
摘要（中）：
生产任务计划在优化生产约束的同时考虑时变能源价格。 能源管理层（EML）与制造领域以及智能电网领域进行通信。 EML接收与工厂工作流程相关的信息，与工厂内运营单位相关的成本以及关税模型和激励措施等静态效用信息。 时间变量能源价格信息是从关于不久的将来时间范围内的周期性价格水平的公用事业获得的。 工作流程被转换为矩阵表示，这是混合整数线性规划（MILP）求解器可以接受的。 表示能源成本和满负荷生产之间权衡的代数因素被最小化，以产生控制生产的生产变量，并限制生产单位和任务在最经济有利的时间段内执行。
