Optimization of the changeover process by implementing SMED

Tematika ovog diplomskog rada je optimizacija procesa izmjene alata. Cilj je smanjenje vremena izmjene alata, a postiže se implementacijom SMED metode. U početnom dijelu rada opisan je pristup proizvodnji poznat pod nazivom vitki (lean) menadžment s naglaskom na totalno produktivno održavanje i nekoliko primjera primjene navedenog pristupa u metaloprerađivačkoj industriji. Nakon toga je detaljnije opisana SMED metoda i nekoliko primjera primjene spomenute metode u metaloprerađivačkoj industriji. U središnjem dijelu rada ukratko je opisana sama tvrtka u kojoj je, na procesima izmjene alata, implementirana SMED metoda. Uz to, provedena je analiza podataka s ciljem optimizacije izmjene alata, odnosno smanjenja vremena izmjene alata. U završnom dijelu ponuđeni su prijedlozi poboljšanja, izračunane potencijalne uštede, predložen plan implementacije poboljšanja i informacijski sustav za praćenje istih.The theme of this graduate thesis is an optimization of the changeover process. The aim is to reduce the changeover time and it is achieved by implementation of the SMED method. At the beginning of this thesis there is a description of a lean management, which is an approach in manufacture, focusing on total productive maintenance. There are also several examples of the aforementioned approach in the metal processing industry. Afterwards, there is a detaliled description of the SMED method and its use in the metal processing industry. The main part contains the description of the comapny itself in which, on the changeover processes, the SMED method was used. Besides that, the analysis was conducted in order to optimize the changeover process, apropos to reduce the changeover time. At the end of this thesis, suggestions for improvements were offered, potential savings were calculated, and a plan how to benefit from implemented changes as well as the IT system to monitor the changes were suggested
