研究了分时电价下以总电力成本最小为目标的节能单机调度问题。在这样的方案中，一天中不同时段的用电量需要不同的价格。要在机器上处理的每个作业的特点是它们的处理时间和每小时的电力消耗。其目的是根据分时电价安排作业的处理，以将总电力成本降至最低。建立了约束个数较少的改进混合整数线性规划模型。计算结果表明，该模型能更有效地解决这一问题。
This paper investigates an energy-conscious single machine scheduling problem to minimize total electricity cost under the time-of-use (TOU) electricity pricing scheme. In such a scheme, the electricity consumed in different periods of a day requires different prices. Each job to be processed on the machine is characterized by their processing time and electricity consumption per hour. The objective is to arrange the processing of the jobs under TOU electricity tariffs so as to minimize the total electricity cost. An improved mix-integer linear programming model with less number of constraints is formulated for the problem. Computational results demonstrate that our model can solve the problem more effectively
