20.500.12556/DKUM-17214 MODEL PRETOKA MATERIALA V PROIZVODNJI MODEL OF THE MATERIAL FLOW IN THE PRODUCTION Namen magistrskega dela je razviti model pretoka materiala v oddelku končne montaže s poudarkom na proizvodnji očal visoke kakovosti. Model pretoka materiala temelji na implementaciji vitkih orodij in tehnik v proizvodni proces, analiziranju materialnih ter informacijskih tokov procesa. Vitka proizvodnja temelji na nizkih stroških proizvodnega procesa ob sočasni visoki kakovosti izdelkov. Osnovna ideja sistema vitkosti, ki se je začela na Japonskem že pred mnogimi leti, je odprava izgub oziroma aktivnosti, ki ne dodajajo vrednosti, zmanjševanje proizvodnih stroškov ter pooblaščanje zaposlenih s pomočjo vključevanja v proces odločanja in aktivne udeležbe od planiranja do izvedbe. Orodja vitkosti so se pričela uporabljati že v Toyota Production System, in sicer: Kaizen, TPM, JIT, SMED, 5S in pregledna tovarna, glajenje proizvodnje in celična proizvodnja. Za pripravo modela pretoka materiala sem z uporabo vitkih orodij izrisala obstoječe stanje v oddelku končne montaže in nato določila izvor izgub ter tako navezala na priložnosti uporabe tehnik vitkosti. Nov oblikovan model pretoka materiala je bil tako zasnovan na zmožnosti reševanja problematike, kot so povečane procesne zaloge, časovne izgube zaradi prekinitev in okvar ter nizkih kakovosti izdelkov. Kot rešitev problema izgub je predlagana uporaba celične proizvodnje ob nadzoru in spremljanju prednosti vitke proizvodnje s poudarkom na modelu pretoka materiala. Kot podpora ovrednotenju vrednostnega toka v oddelku končne montaže in za določanje vpliva uvajanja vitkih orodij v naš proizvodni sistem je bila pri operativnem delu uporabljena računalniška simulacija uvajalnega sistema celične proizvodnje. Z uporabo metodologije vitke proizvodnje je bil pokazan specifičen pogled na proces končne montaže ob jasnih in merljivih rezultatih kakovosti, učinkovitosti in proizvodnosti. The main purpose of this Master`s Thesis was to develop a model of methodology to implement lean manufacturing tools and techniques, with seeks to analyse the internal materials and information flow in an assembly department, with focus on glasses production high quality, specify in assembly process. Lean manufacturing is one of these initiatives that focus on cost reduction by eliminating non-value added activities, whilst ensuring quality. The basic ideas behind the lean manufacturing system, which have been practiced for many years in Japan, are waste elimination, cost reduction and employee empowerment. These tools and techniques have been used in the discrete industry, starting with Toyota Production System. Tools including continuous improvement (Kaizen), Total Productive Maintenance, Just in time, Single-Minute Exchange of Dies, 5S and visual system, production smoothing and cellular manufacturing. To prepare a model of material flow for assembly process of glasses, I started with the procedure of implementing lean tools at a process facility. As basic I used value stream mapping to map current state for assembly department. This helped me to identify source of waste and then identify lean tools. Value stream mapping was used as the main tool to identify the opportunities for various lean techniques. The future state map was developed as accepted model, capable of solving the problems of accumulated intermediate stocks of parts, time losses and quality decreasing of finishing goods. An improvement of this thesis is proposed adopting the cellular manufacturing system, while verifying the advances by means of lean production with focus on material flow model. As supporting tool by implementation assembling cells, I also described a simulation model that was developed to contrast the details with pilot assembling cell, in order to illustrate potential benefits such as reduced production lead-time, higher productivity and lower work-in-process inventory. With lean technics I have managed to add some important detail to a systems view of the assembly process by encouraging managerial interest in the way material and information flows through the production system of glasses. materialni in informacijski tok vitka proizvodnja diagram toka materiala simulacija proces končne montaže model pretoka materiala. material and information flow lean manufacturing value stream mapping simulation sssembly process material flow model. true true false R.
