V diplomski nalogi je predstavljen proizvodni obrat, v katerem se soočajo z neustrezno razmeščenimi delovnimi mesti, kar povzroča dodatne stroške in daljše izdelovalne čase. V teoretičnem delu so opisane osnove planiranja razmeščanja delovnih mest, analiza materialnega toka, predstavljeni pa so tudi različni tipi proizvodnje in notranjega transporta. S pomočjo simulacijskega programa FlexSim smo izdelali model proizvodnje, kjer smo preverili trenutno stanje njenega delovanja. Ustvarili smo še dva alternativna modela z različnima razmestitvama, in jih med seboj primerjali glede na celotno prepotovano pot delavcev in transportnih sredstev. S pomočjo dobljenih rezultatov smo podali predlog za optimalno razmestitev delovnih mest. Analizirali smo zasedenost strojev ali delovnih mest in izkoriščenost delavcev ter določili njihovo število za suboptimalen potek dela znotraj izdelovalnega procesa. In the thesis we are presented with a manufacturing plant, which has an unoptimized layout. This causes additional costs and longer production times. Information regarding layout planning, material flow optimization, production types and internal transportation is presented in the theoretical section of the thesis. With the help of simulation software FlexSim a model of the production system was built, and its performance was tested. Two additional alternative models were created and compared to the existing system regarding total distance travelled by workers and transporters. With the knowledge of the gathered data, a new optimal layout was proposed. The occupancy rate of machines and workstations was analyzed, alongside the utilization of workers. The number of operators was determined for a suboptimal workflow in the production.

Optimizacija proizvodnih procesov v podjetjih, ki želijo dandanes ostati konkurenčna na vse bolj globalnem tržišču, je področje, ki se mu ni mogoče in se mu tudi ne bi smelo izogniti. Vitka proizvodnja podaja številne metode za obravnavanje problemov, povezanih z optimizacijo. Naloga se ukvarja z različnimi metodami vitkosti, nekatere izbrane pa so uporabljene na primeru proizvodnje svetlobnih teles. Na osnovi študije primera s pomočjo analize toka vrednosti in metode določanja časov MTM je predstavljen model za podporo odločanju, s katerim lahko podjetje preveri smiselnost uvedbe sprememb v procesih. Model temelji na izračunu prihranka časa v primerjavi s potrebno investicijo. Z eksperimentom na primeru je bila analiza toka vrednosti prepoznana kot uporabna metoda za odkrivanje izgub v procesih, saj pogosto šele vizualizacija in detajlni popis odkrije šibke točke procesov. Metoda MTM pa je bila prepoznana kot izjemno uporabna za določanje časov v primeru, ko proces še ne poteka, saj omogoča izbiro med različnimi rešitvami oziroma preverjanje možnosti prihranka. Uporaba metod vitkosti vpliva na kazalnike uspešnosti podjetja in s tem finančno dobrobit, pomaga pa tudi pri vzpostavljanju delovnega okolja prijaznega do zaposlenih, tako z vidika kreativnosti kot tudi učinkovitosti. Optimization of production processes is a key field for companies that wish to remain competitive on the increasingly global market, therefore it cannot and should not be avoided. Lean production offers different methods of dealing with problems related to process optimization. My thesis covers different lean methods, while some selected ones are used in the example of lighting equipment production. Based on a case study by means of value stream mapping and MTM time determination method, it presents a model for efficiency evaluation of production process optimization that can be applied by the company to decide whether to proceed with the introduction of changes or not. The model is based on calculation of time savings compared with the required investment. During the case experiment, the value stream mapping method was recognized as an efficient method to define wastes in processes, since often we can clearly define losses only after visualizing and recording a process in detail. The MTM method was recognized as an extremely useful time determination method for processes that are not running in production yet, since it can be used to select from different solutions and to predict saving possibilities based only on the analysis. The use of lean methods has an influence on key performance indicators and therefore on the financial success of the company. It can also help establish employee friendly work environment, from the point of view of creativity as well as efficiency.

Podjetje, ki proizvaja modularne objekte, se srečuje s prostorsko stisko in slabo razporeditvijo delovnih mest na treh različnih lokacijah, zato so stroški transporta med posameznimi lokacijami veliki. Podjetje se je odločilo za združitev proizvodnih procesov na eni lokaciji, za kar pa potrebuje optimizacijo delovnih mest in preračun rentabilnosti investicije. S pomočjo Schmigallove modificirane trikotne metode smo določili suboptimalno postavitev delovnih mest, za optimizacijo delovnih mest pa smo izbrali reprezentativni izdelek in mu določili materialne tokove. V nadaljevanju smo izdelali razporeditev novega stanja in ga umestili v novi proizvodni obrat. Ocenili smo nove razdalje transportnih poti in stroške ter jih primerjali z obstoječimi. Spoznali smo, da s suboptimalno postavitvijo delovnih mest dosegamo bistvene spremembe na področju dolžine transportnih poti in stroškov, ki nastanejo pri transportu. Izdelali smo tudi preračun rentabilnosti in gospodarnosti in ocenili, da je investicija rentabilna in gospodarna. A company that produces modular buildings encounters spatial distress and poor job allocation in three different locations, so transport costs are high. The company decided to merge production processes into one location, which requires optimization of jobs and a calculation of the profitability of the investment. With the help of Schmigall's modified triangular method, we established a suboptimal positioning. For the optimization of jobs, we selected a representative product and determined the material flows for it. Then we have made a distribution of the new condition and placed it in the new production plant. Then we have assessed the new distances of transport routes and costs and compared them with existing ones. We realized that with suboptimal job placement, we made significant changes in the area of transport routes and the costs involved in transport. We also made a calculation of profitability and economy and estimated that the investment is profitable and economical.

V diplomskem delu sem se ukvarjal s problemom razmestitve elementov delovnega procesa pri proizvodnji ležalnika. V teoretičnem delu pod poglavjem ˝ Osnove organizacije proizvodnje in razmestitve proizvodne opreme, smo na hitro predstavili zgodovino organizacije, organizacije dela in navedli nekaj osnovnih teoretičnih predpostavk o razmestitvi elementov delovnega procesa. Predstavili smo tudi potrebni preračun, ki je potreben za uspešno izdelano razmestitev. Te teoretične predpostavke smo potem v tretjem poglavju prinesli na praktični primer proizvodnje ležalnika. Tako smo na podlagi teoretičnih izhodišč oblikovali optimalno razmestitev elementov delovnega procesa pri proizvodnji ležalnika.

The theoretical part, under chapter ˝ Osnove organizacije in razmestitve proizvodne opreme˝ quickly introduce a history of organization, product organization and lay down some theoretical foundations of the arrangement of work places. Thesis also introduces the process of calculating the arrangement of work places. In the practical part the theory is applied to a practical example of deckchair production. On the basic of the theoretical foundations the thesis give the optimal arrangement of work places in a deckchair production

V diplomski nalogi smo se soočili s problemom razmestitve delovnih mest v podjetju Transpak. V teoretičnem delu smo predstavili organizacijo proizvodnje in tudi tipe organizacijskih struktur. Pod poglavjem organizacija proizvodnje smo prikazali tudi postopek preračuna optimalnih kapacitet sistema in razmestitve delovnih mest. To teorijo smo potem aplicirali na praktičnem primeru podjetja Transpak d.o.o. in podali primerne predloge za rešitev problema. Po preračunu smo ugotovili, da je v podjetju možno pridobiti dodaten prostor, katerega lahko uporabimo za različne namene. This thesis elaborates on the problem of the arrangement of work places using the example of Transpak company. The theoretical part describes the different organizational structures of manufacturing companies and introduces the procedures of calculating the optimal capacity and arrangement of work places. In the practical part of the thesis the theory is applied for Transpak d. o o. Furthermore recommendations for the solution of the problem are offered. The calculation shows that the company still has free space that can be used for differential purposes.
