Authorizing can be described as an endogenous system signal that determines whether a job release is allowed or not. Whereas job releases are scheduled in push systems, they are authorized in pull systems since pull-type manufacturing systems are controlled by downstream information. Traditionally, process planning and authorizing are regarded as separate tasks performed sequentially, where authorizing is implemented after process plans have been generated. In view of the fact that their functions are usually complementary, higher productivity and responsiveness can be achieved when they are integrated. Although the studies related with integrated process planning & scheduling (IPPS) are increasingly popular, according to our best knowledge, there is no study researching the integration of process planning and authorizing. This study aims to call attention to the integration of process planning and authorizing through presenting a novel model that is called integrated process planning & authorizing (IPPA). Primary implementation results of IPPA demonstrate that making the integration and hence gaining advantage through integration are pertinent. SMEs can especially get in favour of IPPA because of its slight dependence on (professional) software support.Original Abstract: Autoriziranje se moze opisati kao signal u okviru sustava koji odreduje moze li neki posao zapoceti ili ne. Dok se u push sustavima zapocimanje poslova programira, u pull sustavima oni se autoriziraju buduci da se proizvodni sustavi pull tipa upravljaju downstream informacijama. Tradicionalno se procesi planiranja i autoriziranja smatraju odvojenim zadacima koji se izvrsavaju u slijedu te se autoriziranje izvrsava nakon sto su napravljeni planovi za odvijanje procesa. Imajuci u vidu cinjenicu da su njihove funkcije obicno komplementarne, veca se proizvodnost i reaktivnost mogu postici kad se one integriraju. Iako radovi koji se bave planiranjem i programiranjem integriranih procesa (IPPS) postaju sve popularniji, koliko mi znamo, nema rada koji razmatra integraciju planiranja i autoriziranja procesa. Cilj je ovoga rada upozoriti na integraciju planiranja i autoriziranja procesa predstavljanjem novog modela nazvanog planiranje i autoriziranje integriranih procesa (IPPA). Prvi rezultati primjene IPPA pokazuju da je primjereno vrsiti takvo integriranje te onda i stjecati prednosti kroz tu integraciju. Mala poduzeca (SMEs) narocito mogu imati koristi od IPPA zbog toga sto on slabo ovisi od (profesionalne) sofrverske podrske.
