The more detailed the spatial and temporal discretization is operated, the more information can be gained about the system itself. However, the highest possible resolution of a system is not always of unrestricted advantage, because a closer examination requires more characteristic values and parameters, some of which are hardly available in sufficient quality and are therefore difficult to estimate. Thus, there is a corresponding degree of abstraction for each task, which is subject to change due to increasing requirements and better available input data. The collection of characteristics and parameters can be combined under the term system data analysis. The collection of the control relationships and their implementation for the simulation is the content of the operational analysis. From it 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.
