The following article describes an integrated method to calculate the investment and (cost-) effectiveness of a process optimisation using innovative techniques like RFID. It is based on the research project IdentProLog. Starting with analysing and optimizing processes it‘s possible to evaluate them with a method like activity-based-costing. The detailed information about process-times for each resource will be taken from a material flow simulation. Using this way its possible to create and format data with a high confidential level. Furthermore, it is possible to consider dependencies between technical resources, even in your investment analysis.
