Fuzzy array approach to unit commitment

The paper investigates the unit commitment problem of Swedish power company Sydkraft as a constraint satisfaction problem. The power system is a simplified system with nuclear, thermal, and hydro generators as well as power interchange. In this paper we focus on soft constraints, for instance `approximately equal´, `much larger than´, and `a little´. Several authors have recognized the significance of soft or fuzzy constraints. Our specific objective is to compute a power balance by means of fuzzy array logic in order to accommodate uncertainty
