1.3 Some CPS Design Challenges
1.3.1 Reliability and Uncertainty
Consumers expect CPSs to be reliable and consistent. Indeed, in many applications, such as medi-
cal systems, it is crucial that CPSs perform requested tasks on time and predictably. Unfortunately,
current technologies leave much to be explored in this aspect. e behavior of electronic compo-
nents is not perfectly consistent or predictable.
A disconnection often lies between program execution and physical requirements. A program
has, essentially, 100% reliabilit
