20.500.12556/DKUM-17680 PRENOVA LOGISTIČNEGA INFORMACIJSKEGA SISTEMA V PODJETJU DARS D.D. REDESIGN OF LOGISTICAL INFORMATIONAL SYSTEM IN THE COMPANY DARS D.D. V nalogi smo v analizi stanja sistema predstavili obstoječe logistične procese s poudarkom na ABC in XYZ analizi z namenom zmanjšanja prevelikega stanja zalog na DARS d.d.. Rešitev problemskega stanja smo predstavili v obliki krovne funkcionalne specifikacije za prenovljeni logistični informacijski sistem. Za učinkovito zmanjšanje zalog smo najprej postavili sistem naročanja za artikle razreda A, to so artikli, ki povzročajo 80 % vrednosti vse zaloge. Na podlagi ugotovitev iz ABC in XYZ analize smo predlagali potrebne funkcionalnosti sistema oz. model naročanja za posamezne razrede artiklov iz ABCXYZ analize in ga vgradili v model zasnove informacijskega sistema. Za artikle z naključno porabo smo predlagali vzpostavitev planiranja potreb po materialu. Funkcionalne zahteve za sistem planiranja materialnih resursov - Material requirements planning (MRP) - smo za mesečne in tedenske plane povezali s funkcionalnimi zahtevami za vodenje delovnih nalogov. Za artikle s konstantno ali sezonsko porabo smo definirali sistem naročanja na podlagi signalne in varnostne zaloge, za katero smo določili algoritem naročanja na podlagi analize povprečij porabe materiala preteklih obdobij. Funkcionalno specifikacijo smo sklenili z zahtevami za skladiščno poslovanje oz. WMS (Warehouse Management System). V zaključku smo predstavili prihranke in racionalizacijo z investicijo v informacijsko podporo in preureditev logističnih procesov z ROI (Return on Investment). In this work we presented the existing Logistic processes with emphais on the ABC and XYZ analysis in order to reduce excessive stock levels at DARS, d.d..The solution of the problem sheet was presented in the form of a general functional specifications for the revised Logistics Information System. To effectivelly reduce the stock, we initially set up a system of procurement for items of Class A, these are items that cause 80% of all stocks. Based on the findings of the ABC and XYZ analysis, we proposed the necessary functionality of the system in other words a model of procurement for particular classes of products from the ABC and XYZ analysis. For items with random consumption, we proposed the establishment of Material Regurements Planing (MRP) for monthly and weekly plans, through the functional requirements for managing work orders. For items with constant or seasonal use, we suggested ordering system on the basis of the signal and the buffer stock, for which we determined the ordering algorithm, based on analysis of material consumption averages of past periods. Functional specification was signed with the requirements for Warehouse Management System (WMS). In conclusion, we presented the cost savings and rationalization of the investment in IT support and redesign with Return On Investment (ROI). zaloga ABC YYZ analiza MRP delovni nalogi planiranje naročilo logistični informacijski sistem Stock ABC YYZ analysis MRP Workorders Planning Ordering Logistics Information System true true false Slovenski jezik Angleški jezik Diplomsko delo 2011-03-09 11:28:34 2011-07-19 09:51:14 2022-04-13 09:42:50 2023-12-22 03:36:40 2011 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 6871571 URN:SI:UM:DK:J175UAHD UNI_Bojc_Mihec_2011.pdf UNI_Bojc_Mihec_2011.pdf 1 F06DEEF353C66DF9488725A55C60DB34 04c3dfc2b17385c3623fb95a39452ec83e2fb0affd24fc64fbb645c44c9be02f ec697c21-7c04-11eb-bb7a-00155d0001ca 20.500.12556/dkum/3ea306fa-1868-4862-9eb7-cab107eee7af https://dk.um.si/Dokument.php?lang=slv&id=20749 Fakulteta za organizacijske vede 0 0 0
