Speed scalable problem
This paper deals with single machine scheduling problems, where the machine may be in processing, idle or off state. The machine consumes a different amount of energy in function of its state. Moreover, during processing (ON state), the energy consumption depends on the job. The complexity of these problems, when the jobsâ€™ sequence is fix, for the uniform-speed problem and the speed-scalable problem are analyzed. For this purpose, a dynamic programming approach is proposed to solve these problems by using a finite graph. The results demonstrate that the uniform-speed problem is polynomial of degree 3, and its speed-scalable case is pseudo polynomial.
