\begin{description}
\item[Knowledge based system] \marginnote{Knowledge based system}
Use knowledge (and data) to support human decisions.
Bottlenecked by knowledge acquisition.

Different levels of decision support exist:
\begin{descriptionlist}
\item[Descriptive analytics] \marginnote{Descriptive analytics}
Data are used to describe the system (e.g. dashboards, reports, \dots).
Human intervention is required.
\item[Diagnostic analytics] \marginnote{Diagnostic analytics}
Data are used to understand causes (e.g. fault diagnosis)
Decisions are made by humans.
\item[Predictive analytics] \marginnote{Predictive analytics}
Data are used to predict future evolutions of the system.
Uses machine learning models or simulators (digital twins)
\item[Prescriptive analytics] \marginnote{Prescriptive analytics}
Make decisions by finding the preferred scenario.
Uses optimization systems, combinatorial solvers or logical solvers.
