The paper first describes the main change drivers and takes then a deeper look at how changeability in a previous manufacturing enterprise can be classified and operationalized. The next sections are devoted to changeability in reconfigurable previous manufacturing systems, assembly systems and factories including buildings and infrastructure. New challenges, perspectives and approaches for process plan reconfiguration as well as for Production Planning and Control are discussed. Finally, the evaluation and economic justification of changeability are addressed and a control loop of changeability is presented.enWandlungsfähigkeitMontagesystemPPSProduction Planning and Control (PPC)AnlagenplanungFertigungsplanungFertigungssystemFertigungssteuerung621journal article
