PRISTOPI DOSEGANJA VITKE PROIZVODNJE

PEČAR, BORIS (author), Atanasijević-Kunc, Maja (mentor)

Živimo v času, ko smo priča stalnim pritiskom zniževanja cen izdelkov. Ponudnikov različnih izdelkov in storitev je čedalje več in konkurenca je neizprosna. Nekateri se s tovrstnimi problemi ne uspejo uspešno spopasti in selijo proizvodnjo v države s cenejšo delovno silo. Dokler je delovna sila v teh deželah dejansko cenejša, se jim ni potrebno pretirano ukvarjati z optimizacijo proizvodnje. Nekateri drugi pa iščejo skrite rezerve in prihranke pri svojem delu in tako vsak na svojem področju prispevajo k zmanjševanju končne cene produkta. Poudariti je potrebno, da v tem primeru pride tudi do ohranjana delovnih mest, kar je za vsako okolje zelo pomembno. V diplomski nalogi je opisana optimizacija proizvodnje prikazovalnika za spremljanje gledanosti televizijskih programov GPM (Global People Meter) ali TV-metra, kot ga tudi imenujemo. Pri tem je uporabljena metoda vitke proizvodnje s katero smo uspešno pocenili proizvodnjo izdelka. Ker v podjetju nismo imeli dovolj znanja o vitki proizvodnji, smo se odločili za intenzivno usposabljanje ekipe ljudi, ki je sodelovala na projektu. Pri tem smo imeli veliko podporo naših predavateljev iz Slovenskega instituta za kakovost in meroslovje, ki so nam večkrat priskočili na pomoč z izobraževanjem, nasveti in idejami. Bistvo optimizacije, ki rezultira v vitko proizvodnjo, je v tem, da je v projekt vključenih čim več različnih ljudi in/ali različnih enot. S tem dosežemo širši pogled na celoten proizvodni proces in preprečimo, da bi z rešitvijo enega problema nastalo več drugih. Tako smo aktivnosti izdelave našega produkta optimizirali skozi celotno proizvodno verigo, od nabave, izdelave pa do skladiščenja. S tem smo dosegli maksimalne prihranke, saj smo upoštevali vse operacije skozi katere mora iti izdelek. Delo je urejeno na naslednji način. V uvodu kratko predstavimo obravnavano proizvodnjo in izdelek, ki je namenjen spremljanju gledanosti televizijskih programov. Sledi predstavitev pomembnih informacij, ki zadevajo vitko proizvodnjo. V tretjem poglavju smo predstavili analizo stanja proizvodnje pred optimizacijo, v četrtem pa smo predstavili detektirane in realizirane izboljšave, ki so zadostile zahteve vitke proizvodnje. V zaključku smo kratko povzeli bistvene ukrepe in aktivnosti ter ugotovljene prihranke. Opisali smo tudi nekatere načrte, ki se jim nameravamo posvetiti v prihodnosti.

• Title: APPROACHES OF ACHIEVING A LEAN MANUFACTURING

Abstract

We are living at a time where product prices are constantly being pushed down. The number of articles and services providers is rising and competition is fierce. Some of these providers are able to tackle such issues by moving their production to countries with a cheaper workforce. Production optimisation is not a priority as long as the workforce in that country is actually cheaper. However, others are seeking hidden reserves and trying to save money, thereby helping to reduce the final price of the product. It should also be emphasised that the latter option safeguards jobs, which is important for every environment. The thesis deals with the optimisation of the production of the Global People Meter (GPM), which is a television audience measurement tool. We used the lean manufacturing method and successfully reduced the costs of the production. The company lacked knowledge of lean production, which is why we opted for an intense training course for the people involved in the project. In this respect, the lecturers from the Slovenian Institute of Quality and Metrology provided excellent support with education, advice and ideas. The main idea behind optimisation that leads to lean manufacturing is that the project involves as many different people and/or units as possible. As a result, the entire production process can be put in a wider perspective to prevent several new problems from emerging after solving one. The production of our product was being optimised throughout the production chain from the purchase and production phase to storage. Our efforts resulted in maximal savings because every operation connected to the product was taken into account. The thesis is organised in the following way. The introductory part presents the production and the product that measures television audience. The second chapter outlines the vital information relevant to lean manufacturing. The third chapter analyses the production before optimisation, while the fourth presents the improvements we detected and implemented to meet the requirements of lean manufacturing. The last chapter summarizes the key measures and activities and discusses the savings. It also touches some of the future plans.
