20.500.12556/DKUM-69065 A statistical model for shutdowns due to air quality control for a copper production decision support system Statistični model zaustavitev zaradi nadzora kakovosti zraka pri proizvodnji bakra: sistem za podporo odločanju Background: In the mid-1990s, a decision support system for copper production was developed for one of the largest mining companies in Australia. The research was conducted by scientists from the largest Australian research center and involved the use of simulation to analyze options to increase production of a copper production facility. Objectives: We describe a statistical model for shutdowns due to air quality control and some of the data analysis conducted during the simulation project. We point to the fact that the simulation was a sophisticated exercise that consisted of many modules and the statistical model for shutdowns was essential for valid simulation runs. Method: The statistical model made use of a full year of data on daily downtimes and used a combination of techniques to generate replications of the data. Results: The study was conducted with a high level of cooperation between the scientists and the mining company. This contributed to the development of accurate estimates for input into a support system with an EXCEL based interface. Conclusion: The environmental conditions affected greatly the operations of the production facility. A good statistical model was essential for the successful simulation and the high budget expansion decision that ensued. Ozadje: V sredini 1990-ih let je bil razvit sistem za podporo odločanju za proizvodnjo bakra za eno od največjih rudarskih podjetij v Avstraliji. Raziskava je bila izvedena s strani znanstvenikov iz največjega avstralskega raziskovalnega centra in vključuje uporabo simulacije za analizo možnosti za povečanje proizvodnje bakra. Cilji: Opisan je razvoj statističnega modela zaustavitev zaradi nadzora kakovosti zraka in prikazane so nekatere analize podatkov, izvedene v okviru projekta simulacije. Simulacija, ki je vključevala več modulov in statistični model zaustavitev je bistvenega pomena za veljavnost simulacijskih tekov. Metoda: uporabili smo statistični model, ki izhaja iz podatkov o dnevnih zastojev za eno leto, in kombinacijo tehnik za ustvarjanje replik podatkov. Rezultati: Raziskava je zahtevala visoko stopnjo sodelovanja med znanstveniki in rudarsko družbo. Na ta način je bil z uporabo preglednice izdelan vmesnik za vnos ustrezno natančnih ocen v simulacijski sistem. Zaključek: Okoljske razmere močno vplivajo na poslovanje v proizvodnem obratu bakra. Zato je dober statistični model bistvenega pomena za uspešno simulacijo in podporo odločanju. decision support system simulation statistical modelling rudarstvo baker proizvodnja vodenje odločanje simulacija modeli true true true Angleški jezik Slovenski jezik Znanstveno delo 2017-11-28 14:05:22 2017-11-28 14:06:22 2022-08-01 16:51:07 2019-07-11 17:19:46 2015 0 0 str. 198-202 št. 3 Letn. 48 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1318-5454 005.311.6:622.343 610909 283349504 10.1515/orga-2015-0014 1318-5454 URN:SI:UM:DK:FV4CZPCD Organizacija_2015_Aboura_A_Statistical_Model_for_Shutdowns_due_to_Air_Quality_Control_for_a_Copper_Production_Decision_Support_System.pdf Organizacija_2015_Aboura_A_Statistical_Model_for_Shutdowns_due_to_Air_Quality_Control_for_a_Copper_Production_Decision_Support_System.pdf 1 7EB2E7B3009F076ED345688431583DAA 5eb68159c40e6937faf0a92a311f16bdfe55e3bf58c7a14dba98cd542ba33268 84865bd1-7c0f-11eb-bb7a-00155d0001ca 20.500.12556/dkum/3bd2e4a7-1580-4a04-a246-59543f7eb691 https://dk.um.si/Dokument.php?lang=slv&id=120519 https://www.degruyter.com/view/j/orga.2015.48.issue-3/orga-2015-0014/orga-2015-0014.xml 1 https://dk.um.si/Dokument.php?lang=slv&id=120520 Fakulteta za organizacijske vede Organizacija 0 0 0
