Abstract
The complexity of an assembly system is caused by two factors: by a time-independent poor design that causes low efficiency (system design), and by a time-dependent reduction of system performance due to system deterioration or to market or technology changes (system dynamics). To optimize the efficiency and changeability of an assembly system, both factors must be considered in order to reduce the system’s entire complexity [1]. The presented approach provides methodological guidance in the systematic complexity reduction and in the development of efficient, flexible and changeable assembly systems. Thus, it accelerates the planning process and increases quality of the planning results. With the help of practical applications in different industries and the obtained results, the validity of the approach is illustrated.
