20.500.12556/RUL-112582 Odpravljanje zapravljanj v proizvodnji štancanih delov Eliminating wastes in the production of stamped parts Podjetje se že nekaj časa srečuje s slabimi rezultati na eni od proizvodnih linij štancanja. Odločili smo se, da bomo preučili trenutno stanje in na podlagi rezultatov analiz predlagali ukrepe, ki bodo pripomogli k odpravljanju zapravljanj, torej vseh dejavnosti, ki ne prispevajo k dodani vrednosti in povzročajo stroške. Sprotni preračuni skupne učinkovitosti opreme so nam omogočali vpogled v trenutno dogajanje in nadaljnjo primerjavo predvidenih rezultatov med seboj. Glede na šibke točke procesa smo po principih metode stalnih izboljšav kaizen oblikovali smiselne ukrepe za izboljšave. Predlagane ukrepe smo razvrstili v tri nivoje glede na višino potrebne investicije za njihovo uvedbo, jih opisali ter navedli pričakovan učinek na proces. Na podlagi rezultatov OEE in višine investicij smo ugotovili, da je najbolj smiselna vpeljava ukrepov brez vlaganj v kombinaciji z ukrepi, ki za izvedbo zahtevajo srednji rang investicije. The company has been experiencing poor results on one of its stamping production lines. We have analysed the current situation with an aim to propose measures that will help eliminate wastage - activities that do not add value and cause costs. The ongoing calculations of the overall equipment effectiveness (OEE) provided us with an insight into the current developments and a further comparison of the projected results with each other. We have designed improvement measures considering the weaknesses of the process using the Kaizen - continous improvement approach. We divided the proposed measures into three levels according to the amount of investment required for their introduction, described them and stated their expected impact on the process. Based on the results of OEE and the amount of investments, we have found that the most sensible step is implementation of a combination of measures that don't require an investment with measures that require a medium level of investment. proizvodnja procesi učinkovitost izboljšave razpoložljivost zapravljanja štancanje production processes effectiveness improvements availability wastage stamping true false false [N.
