Abstract:Učinkovito spremljanje zanesljivosti in razpoložljivosti proizvodne opreme ima v konkurenčnem boju na globalnih trgih, na katerih je prisoten tudi Lek, d.d., vedno pomembnejšo vlogo. V sklopu magistrske naloge smo oblikovali model baze podatkov za spremljanje razpoložljivosti pakirnih linij v njegovi proizvodni enoti, Pakirnem centru Lendava. Teoretični del se začne s predstavitvijo analize načinov odpovedi, njihovih vzrokov in učinkov. Sledi opis izbranih kvantitativnih karakteristik zanesljivosti in razpoložljivosti. Zadnji del se nanaša na zbiranje podatkov in bazo podatkov za spremljanje razpoložljivosti. Naloga v nadaljevanju proučuje, kateri podatki so za spremljanje razpoložljivosti pakirnih linij v Pakirnem centru Lendava potrebni, kateri so že na voljo in katere še potrebujemo. Da to ugotovimo, je potrebno najprej proučiti obstoječe stanje. Obstoječe stanje smo popisali z opisom samega sistema, sistema vzdrževanja, načina zbiranja in obdelave podatkov, vezanih na razpoložljivost sistema, ter z analizo uporabnosti teh podatkov. Temu je sledilo oblikovanje modela baze podatkov za spremljanje razpoložljivosti pakirnih linij. V zasnovi modela smo opredelili sistem, njegovo glavno funkcijo in odpovedi ter določili način zbiranja potrebnih podatkov o odpovedih in vzdrževanju sistema. Nadalje smo izbrali relevantne karakteristike razpoložljivosti na nivoju komponent, sklopov, funkcionalnih enot in sistema. Podali smo tudi enačbe za izračun točkastih ocen izbranih kvantitativnih karakteristik. V zaključku naloge je podana ocena učinkov uvedbe modela v prakso, navedene so omejitve, ki se pri tem pojavijo, in opisana je možnost nadgradnje modela ter njegove širše uporabe.

Title:DATA BASE FOR AVAILABILITY MONITORING OF PACKAGING LINES IN LEK, D.D., PACKAGING CENTER LENDAVA
Abstract:The role of effective monitoring of reliability and availability of production equipment in the competitive struggle on global markets ‒ where Lek, d.d., is also present ‒ is increasing. This master’s thesis presents the development of the database model for availability monitoring of packaging lines in its production unit, the Packaging center Lendava. The theoretical part first presents the analysis of failure modes, their causes and effects. A description of the selected quantitative characteristics of reliability and availability follows. The last part refers to the data collection and database for availability monitoring. The thesis also examines which data are needed to monitor availability of the packaging lines in the Packaging center Lendava, which are already available and which are still missing. It is thus necessary to first examine the existing state. The existing state includes descriptions of the system itself, the system maintenance, the methods of collecting and processing data related to system availability, and the analysis of usability of this information. This is followed by the creation of the database model for availability monitoring of the packaging lines. Based on the design of the model, we define a system, its main function and failure modes, and identify the method of collecting the necessary data on failures and maintenance of the system. Furthermore, we have selected the relevant characteristics of the availability at the level of components, assemblies, functional units and system. Besides, we propose formulas for calculation of statistical estimates of selected quantitative characteristics. The thesis concludes with an estimation of the effect of the model implementation, the limitations are listed, and possible model upgrades and its wider usage are described.
Keywords:availability, reliability, quantitative characteristics, database, packaging line
