Development of a Functional Modelling Approach and a Concept of Common Functions for Serial Products

Modern engineering design requires flexible functional modelling methods that work across multiple product generations. This thesis presents a new approach focused on functional modelling and identifying "common functions" functions that stay stable or change only slightly between generations. Recognizing these functions can reduce development time, save resources, and improve system quality. A key part of the approach is creating a library that stores and manages these common functions. Such a library provides quick access to proven solutions, supports consistent design, and helps engineers adapt functions to new product generations. Overall, combining this modelling approach with a structured function library boosts development efficiency, enhances product quality, and accelerates time-to-market in a competitive environment.
