Production companies in the area of sheet metal processing need to use innovative manufacturing processes in order to improve their competitive strength. However, the implementation of new processes is usually inhibited by the financial effort and the lack of precise information about their technological and economic capabilities. Established methods suppose knowledge about decision criteria and focus mainly on investment costs. The system development aimed at the design and implementation of methods for the characterisation and assessment of innovative manufacturing process. The technological capabilities are described in terms of geometric features and material properties and assessed taking the production program into account. The manufacturing process is modelled using a continuos simulation model concerning process steps, products, machines and tools. Because of the vague knowledge about a innovative non-implemented manufacturing process the simulation quantities might be defined by fuzzy sets. The economic benefits are predicted evaluating scenarios, which lead further to the comparison of alternative technologies and to the optimisation of the innovative process chain.
