Production processes improvement using Lean management tools

Tema ovog rada je unaprjeđenje proizvodni procesa alatima Lean menadžmenta. U radu je opisana povijest industrijskog inženjerstva i lean menadžmenta te detaljnije razrađeni alati leana. Nakon pregleda literature i teorije, u praktičnom djelu razrađena je metoda kojom je povećana produktivnost u proizvodnom poduzeću Feroimpex. Metoda se sastojala od snimanja trenutnog stanja kroz vremensko - funkcijsku mapu, prepoznavanja i kategoriziranja gubitaka te standardizacije procesa uz pomoć standardnih operativnih procedura. Postupak je proveden na klasičnom i poboljšanom procesu te su potom rezultati uspoređeni. Na kraju je dan zaključak kako nastaviti s unaprjeđenjem navedenog procesa.The topic of this paper is the improvement of the production process with the tools of Lean management. The paper describes the history of industrial engineering and lean management and elaborates on lean tools in more detail. After reviewing the literature and theory, in the practical part, a method was developed which increased productivity in the production company Feroimpex. The method consisted of recording the current state through a time - function map, recognizing and categorizing losses, and standardizing the process with the help of standard operating procedures. The procedure was performed on a classical and improved process and then the results were compared. Finally, a conclusion was given on how to continue to improve this process
