Modelling of distributed event-discrete systems using digital twins. In more detail, the present disclosure relates to the field of modeling distributed event-discrete systems using digital twins for subsequent use of the models during real time control of distributed even-discrete systems. Heretofore, there are provided a computer implemented meta model, modeling methods using the computer implemented meta model, and related modeling engine and service engine. In the computer implemented meta model at least one state in the at least one state model is represented by a set of partial states using different levels of data abstraction according to a meta description, a range of values characterizing a target for a considered state, and a range of values representing an actual constellation of a considered state.
