High Quality Content by WIKIPEDIA articles! Time-utility functions (TUF's, also called time-value functions) are needed for real-time computing when a deadline occurs. They were introduced by E. Douglas Jensen in 1977 as a way to overcome the limited expressiveness in classic deadline constraints in real-time systems. In a graphical interpretion, the utiliy (positive for reward, negative for penalty) is plotted over the time. A deadline then represents the point where the utility changes from positive to negative. In computer science and programming, this is when a task must be terminated. If not, an exception occurs, which usually leads to an abortion. As such, a TUF is a generalization of deadline constraints in everyday life. With TUF time constraints, timeliness optimality criteria can be specified.
