Abstract

Proizvodna podjetja se danes soočajo s proizvodnjo vedno večjih količin izdelkov, ki se med seboj razlikujejo. Visoka raven individualizacije izdelkov in kompleksnosti predstavljata velik izziv za upravljanje interne logistike, še posebej za proces oskrbovanja montažnih linij. V procesu oskrbovanja moramo skrbeti za dostavo pravilnih komponent, komponent v pravi količini, kakovosti, ob pravem času in na pravo mesto. Zaradi navedenega je ključna izbira najprimernejše strategije oskrbovanja. Strategije oskrbovanja delimo na strategijo hranjenja materiala ob montažni liniji v transportno-skladiščnih enotah, strategijo dostavljanja materiala v zahtevanem zaporedju ob montažni liniji, strategijo dostavljanja materiala ob montažno linijo v manjših zabojih in količinah, prilagojenih porabi v definiranem časovnem oknu, in dve različni strategiji kompletiranja. Poleg omenjenih je pri oskrbovanju pogosto prakticiranje uporabe supermarketov in kartic KANBAN. Zaradi razlik v lastnostih komponent se uvaja tudi hibridno oskrbovanje, ki kombinira pravila dveh ali več strategij. Strategije se med seboj razlikujejo po uporabi, načinu transporta, pripravi in načinu popolnjevanja zalog. Velik vpliv na izbiro in izboljšanje strategij oskrbovanja ima prakticiranje vitkosti v podjetju. Podjetja uvajajo vitkost z namenom odprave izgub in kontinuiranega izboljševanja procesov. Pri hibridni strategiji je izbira kombinacije strategij odvisna od lastnosti vsake komponente posebej. V magistrskem delu smo pozornost namenili metodi Plan-Do-Check-Act (PDCA) in metodi Axiomatic Design in ju kasneje uporabili tudi pri celoviti prenovi oskrbovanja montažne celice v realnem podjetju. Podjetju smo predlagali uporabo metode za izbiro strategije, predlagali pa smo tudi nov proces oskrbovanja montažne celice s poudarkom na uvedbi digitalnega informacijskega sistema za podporo v procesu oskrbovanja z namenom zmanjšanja napak. Obravnava konkretnega primera v praksi nam je pomagala pridobiti vpogled v oskrbovanje montažne celice in se soočiti z izzivi iskanja priložnosti za izboljšave in izvajanja sprememb. Po zaključku dela na izbranem primeru smo pridobljene izkušnje povzeli in posplošili ugotovitve na način, da bodo uporabne tudi za druga podjetja z montažnimi celicami.

Secondary title:	Complete renovation of the assembly cell feeding
Secondary abstract:	Manufacturing companies nowadays face the challenge of having to produce increasing amounts of diverse products. The high level of product individualization and complexity poses a significant challenge to internal logistics management, especially to the assembly cell feeding process. In the feeding process, it is essential to ensure the delivery of the right components, in the right quantity and quality, at the right time, and to the right location. Due to these factors, the key is the selection of the most appropriate feeding strategy. Feeding strategies are classified into line-stocking, sequencing, boxed supply, stationary kitting and travelling kitting strategies. In addition to these, the use of supermarkets and KANBAN cards is often practiced in the feeding process. Due to differences in component properties, a hybrid feeding strategy is also introduced, combining the rules of two or more strategies. Strategies differ in usage, transport method, preparation, and the inventory replenishment method. The practice of lean principles in the company has a significant impact on the selection and improvement of feeding strategies. Companies introduce lean practices to eliminate losses and continuously improve processes. In the hybrid strategy, the selection of a strategy combination depends on the characteristics of each component. In the master's thesis, we focused on the Plan-Do-Check-Act (PDCA) method and the Axiomatic Design method, later applying them to the comprehensive renovation of the assembly cell feeding process in a selected company. We proposed the use of the strategy selection method and suggested a new assembly cell feeding process, with an emphasis on the introduction of a digital information system to support the feeding process and reduce errors. Addressing a specific practical case helped us gain insight into the feeding of an assembly cell and tackle the challenges of finding opportunities for improvement and implementing changes. After completing the work on the selected case, we summarized the acquired experiences and generalized the findings in a way that will be useful for other companies with assembly cells.
