Abstract

Tema ovog rada je optimizacija proizvodnih procesa primjenom Lean Six Sigma metodologije. Kroz prvi dio rada daje se teorijska podloga o samoj metodologiji koja se nametnula kao odličan pristup za postizanje operativne izvrsnosti i optimizaciju proizvodnih procesa. U nastavku se detaljno obrađuju alati Lean Six Sigma metodologije koji će se primijeniti u praktičnom dijelu rada i koji su odličan korak prema optimizaciji procesa u proizvodnji. Nakon temeljitog proučavanja relevantne literature u prvom dijelu rada, drugi dio fokusira se na praktičnu primjenu stečenog znanja s ciljem poboljšanja proizvodnih procesa. U praktičnom dijelu mapirani su procesi proizvodnje baterijskih paketa električnih vozila i detektirane nesukladnosti koje se događaju unutar procesa. Nakon identificiranja nesukladnosti napravljena je analiza potencijalnih uzroka, prikaz rješenja tih nesukladnosti i pristup prema njihovoj prevenciji u budućnosti. U drugom dijelu napravljen je Ishikawa dijagram s ciljem rješavanja aktualnih uzroka problema kako bi se zadovoljili dogovoreni rokovi projekta te su za svaki od glavnih uzroka problema dani prijedlozi rješenja.

Abstract (english)

The topic of this paper is the optimization of production processes using the Lean Six Sigma methodology. Through the first part of the paper, the theoretical background is given on the methodology itself, which has been imposed as an excellent approach for achieving operational excellence and production processes optimization. In the continuation of the paper, the tools of the Lean Six Sigma methodology that will be applied in the practical part of the work and which are an excellent step towards optimizing the production process are discussed in detail. After a thorough study of the relevant literature in the first part of the paper, the second part focuses on the practical application of the acquired knowledge with the aim of improving production processes. In the practical part, the production processes of electric vehicle battery packs are mapped and non-conformities that occur within the process are detected. After identifying the non-conformities, an analysis of potential causes was made, a presentation of solutions to these non-conformities and an approach to their prevention in the future. In the second part, an Ishikawa diagram was created with the aim of solving the current causes of the problem in order to meet the agreed project deadlines, also suggestions for solutions were provided for each of the main causes of the problems.
