Abstract: A method and an apparatus provide a quantitative process simulation model with systematic search and optimization techniques to automatically find and compare improvement strategies and especially provide for inspecting at least one device control instruction. Input parameters are transformed into output parameters, while a performance value is measured and based on said measurement appropriate device control instructions, which are used for transforming the input parameters into output parameters, are output. Application can be found in several scenarios related to process engineering, process optimization and especially optimizing performance values for operating a device.

Abstract: A method and a respective apparatus for simulating a behaviour of a device does not have to change the mode of operation of the device. Furthermore it is possible to simulate improvement strategy step-wise and therefore calculate an impact of a process improvement project. Therefore an iterative simulation procedure is provided, which may find application in process improvement, such as software engineering process improvement, as well as optimization of performance parameters of devices and machines.
