Abstract

V času zaostrenih gospodarskih razmer je za preživetje in konkuriranje podjetja potrebno vsak proizvodni proces obvladovati in poznati do najmanjših podrobnosti. S poznavanjem procesa podjetje lažje pristopi k povečanju učinkovitosti. Cilj raziskave diplomskega dela je analizirati obstoječe stanje ter poiskati ustrezne tehnike in orodja managementa kakovosti, ki bi pozitivno vplivala na učinkovitost procesnoproizvodnih področij. Izhodiščni problem je vezan na vprašanje, kako naj podjetje zagotovi višjo učinkovitost v kovinskoproizvodnem podjetju z zelo širokim asortimanom izdelkov. Da bi odkrili in izkoristili področja, kjer obstaja potencial za izboljšanje učinkovitosti, smo vzpostavili sistem za ocenjevanje učinkovitosti s kazalnikom OEE (Overall Equipment Effectiveness). Analiza OEE se navezuje na stroškovno mesto 35391 v podjetju TRO, d. o. o., in sicer na rezkalni stroj CNC. Na osnovi analize obstoječega stanja smo ugotovili, da je skupna učinkovitost opreme (OEE) znašala 56,8 %. Poleg izračuna kazalnika OEE smo v okviru analize obstoječega stanja proučili tudi vzroke za reklamacije, in sicer je 31,57 % vseh reklamacij v obravnavanem obdobju bila posledica dimenzijskega odstopanja izdelkov od predpisanih toleranc. Na temelju dobljenih rezultatov v povezavi z ustreznimi teoretičnimi spoznanji utemeljujemo orodja 5S, TPM in FMEA kot najprimernejše modele za implementacijo. Predvideni efekti teh orodij so povečanje razpoložljivosti stroja in zmanjšanje nekakovostnih proizvodov ter povečanje produktivnosti in avtonomnosti zaposlenih. Na osnovi teoretičnih spoznanj predvidevamo tudi, da bi s slednjimi različnimi organizacijskimi pristopi dosegli zmanjšanje števila reklamacij.

Secondary title:	IMPROVEMENT OF THE OEE BY MEANS OF QUALITY MANAGEMENT TOOLS
Secondary abstract:	In times of tightened economic circumstances the competitiveness and survival of the company depends on knowing and mastering each individual process in detail. Through that knowledge optimum efficiency can be achieved. The aim of this Diploma Thesis is to analyze current techniques and tools of quality management, which would have a positive influence on the efficiency of processing and manufacturing procedures. The core problem is linked to the question; how can higher efficiency be ensured in a company with a broad assortment of products? To discover and exploit areas, where the potential for improvement exist, we established a system for evaluating efficiency with Overall Equipment Effectiveness (OEE) indicator. This analysis is concerning the 35391 cost center in the TRO, d. o. o., (ltd) and it’s milling machine. Based on the analysis of current situation in studied company, the Overall Equipment Effectiveness (OEE) was estimated to be on average around 56.8 %. Apart from calculating the OEE, we also examined the causes for complaints. It was found that incapability of meeting dimensional product specification was the foremost important cause for complaints (31.57 %). Based on research results, backed by relevant theoretical conclusions, we found that the tools 5S, TPM, and FMEA as most suitable models for the task. Foreseen effects of those tools decreased the numbers of faulty products and increased availability of the machine, therefore increasing productivity and autonomy of employees. Thus, theoretically the various organizational approaches should reduce the numbers of rejected and/or damaged products.
