Energy Efficiency And Renewable Energy Management With Multi-State Power-Down Systems, James Andro-Vasko, Wolfgang W. Bein, Hiro Ito

Computer Science Faculty Research

A power-down system has an on-state, an off-state, and a finite or infinite number of intermediate states. In the off-state, the system uses no energy and in the on-state energy it is used fully. Intermediate states consume only some fraction of energy but switching back to the on-state comes at a cost. Previous work has mainly focused on asymptotic results for systems with a large number of states. In contrast, the authors study problems with a few states as well as systems with one continuous state. Such systems play a role in energy-efficiency for information technology but are especially important …
