20.500.12556/RUL-166107 Dvig avtonomije ročne montažne linije z uporabo metod vitke proizvodnje Increasing the autonomy of a manual assembly line using LEAN manufacturing methods V magistrski nalogi smo raziskali možnosti povečanja avtonomije operaterjev na ročni montažni liniji, na kateri se sestavlja več identov izdelka. Nekatere aktivnosti ob menjavah identov izvajajo vzdrževalci, kar ob njihovi odsotnosti vodi do zastojev. Naloga vključuje teoretični pregled nekaterih konceptov Toyotinega proizvodnega sistema, metode hitre menjave orodij (SMED) in standardizacije dela. Izvedli smo analizo trenutnega postopka montaže izdelkov in obstoječega stanja menjav. Posebna pozornost je bila namenjena prepoznavanju potrat, ki se pojavljajo med temi postopki. Z metodo SMED smo optimizirali aktivnosti med menjavami, ki jih je mogoče prenesti z vzdrževalcev na operaterje. Z metodami standardiziranega dela in balansiranja operacij smo določili optimalno razporeditev dela operaterjev med menjavami. Za lažje načrtovanje in izvedbo menjav smo ustvarili preglednico menjav med identi in matriko menjav. Predpisan je nov postopek menjave identov, s katerim lahko znatno znižamo čas zastojev, ki nastanejo zaradi odsotnosti vzdrževalcev in dvignemo avtonomijo montažne linije. In this master's thesis, we investigated the possibilities of increasing the autonomy of a manual assembly line, on which several product variants are assembled. Some activities during variant changeovers are carried out by maintenance staff, which in their absence, leads to downtime. Our work includes a theoretical review of key concepts of the Toyota Production System, Single-minute exchange of die (SMED) and standardised work. We carried out an analysis of the current product assembly and changeover process. Special attention was paid to identifying wastes that occur during these procedures. The SMED method is used to optimise activities during the changeover process, that can be transferred from maintenance workers to line operators. Using methods of standardised work and balancing of operations, we determined the optimal distribution of work during changeovers between line operators. To simplify the planning and execution of changeovers, we have created a table of changeovers between variants and a matrix of changeovers. A new procedure for changeover of variants has been prescribed, with which we can significantly reduce downtime due to the absence of maintenance personnel and increase the autonomy of the assembly line. toyotin proizvodni sistem TPS metoda hitre menjave orodij SMED standardizacija dela potrate dvig avtonomije montažne linije toyota production system TPS single-minute exchange of die SMED standardised work wastes raising autonomy assembly lines true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2024-12-20 07:30:05 2024-12-20 07:30:09 2025-01-07 11:50:19 0000-00-00 00:00:00 2024 0 0 XX, 63 f. 2024 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 658.5:629.331(043.2) 270360 221171715 38459.pdf 38459.pdf 1 1913C5D577C4BE7E1D5950A51BF1C2BD d4dd4cb8dfb2a29bce93b9ecfdbf087192be984cf3d24942d82d9de0297f9fd8 49fa1bd9-be9b-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=197494 Fakulteta za strojništvo 0 0 0
