Simulation of production processes by means of continuous fluid models

A method of simulating a production process on the basis of a continuous fluid model with discrete time evolution is described. The method of simulating makes use of assigning production and processing resources of various stations of the fluid model to various fluids with respect to a priority identifier of the fluids. Division of the station resources to various fluids is further based on a momentary amount of the various fluids. Based on the assignment of the station resources to the various fluids, the time evolution of the fluid amounts are determined without having to perform time and resource consuming optimization. Additionally, assignment of station resources can be manually and temporarily modified by a fluid manipulation means allowing for a universal and dynamic modification of the behavior of particular stations without interrupting or affecting the entire simulation process.
