The more detailed you carry out the spatial and temporal discretization, the more information can be gained about the system itself. However, the highest possible resolution of a system does not always provide the best advantage, because a closer examination requires more characteristic values and parameters, some of which may not be available in sufficient quality and are therefore difficult to estimate. Thus, there is a suitable degree of abstraction for each task, which can however be subject to change due to increasing requirements and improved quality of available input data.

The collection of characteristics and parameters can be described using the term system data analysis. The collection of the control relationships and their implementation for the simulation is called the operational analysis. From the latter, a kind of second system logic arises, which does not contain flow relations but the logical connections of the state variables to derive the output decisions. It can be called control logic.
