20.500.12556/DKUM-65427 Sugar beet production a system dynamics model and economic analysis Pridelava sladkorja in sladkorne pese model sistemske dinamike in ekonomska analiza Background and Purpose: The sugar beet is the main field crop used for sugar production in the temperate climatic zone. Since investment in sugar beet industry are long term and ireversible the decision support and economic analysis are required in order to maximise investment returns. Methodology: A system dynamics methodology was chosen to model the impacts of regional sugar factory investments. We present the basic concepts of system dynamics (SD) models and their development in the case of sugar beet production and processing systems. Sugar beet economics are also analyzed using the static technological economic simulation model. Results: The simulation provides answers to strategic questions related to the total sugar beet production and processing system and will be used for the simulation of different scenarios for sugar production and their impact on economic and environmental parameters at an aggregate level. Furthermore, the feasibility analysis of sugar beet production revealed that at the current price and intensity levels (yields), we can expect profitable sugar beet production for both white sugar and ethanol. Conclusion: Preliminary results show that under expected production parameters the sugar beet processing and production would be economically feasible. Ozadje in namen: Sladkorna pesa je glavna kultura, ki se uporablja za proizvodnjo sladkorja v zmernem klimatskem pasu. Ker so naložbe v predelavo sladkorne pese dolgoročne in ireverzibilne, je z uporabo ustreznih orodij potrebno odločitve pretehtati Metodologija: Metodologija sistemske dinamike je bila izbrana za podporo odločanju na regionalnem nivoju pri planiranju investicij v predelavo sladkorne pese. Predstavljamo osnovne pojme sistemske dinamike (SD) in razvoj modela pridelave in predelave sladkorne pese in predelovalnih sistemih. S pomočjo tehnološko ekonomskega simulacijskega modela pa analiziramo ekonomiko pridelave sladkorne pese. Rezultati: Model ponuja odgovore na strateška vprašanja, ki so povezana s predelavo sladkorne pese in bo uporabljen za simulacijo različnih scenarijev za proizvodnjo sladkorja in njihovega vpliva na gospodarske in okoljske parametre na agregatni ravni. Analiza ekonomske upravičenosti proizvodnje sladkorne pese je pokazala, da pri sedanjih cenah in intenzivnosti pridelave (pričakovan pridelek), lahko pričakujemo dobičkonosno proizvodnjo sladkorne pese tako za beli sladkor kot etanol. Zaključek: Preliminarni rezultati so pokazali, da ob doseganju predvidenih parametrov lahko pričakujemo ekonomsko upravičeno pridelavo in predelavo sladkorne pese. sugar beet modeling system dynamics economic feasibility sladkorna pesa modeliranje sistemska dinamika ekonomska upravičenost true true true Angleški jezik Slovenski jezik Znanstveno delo 2017-04-04 14:41:11 2017-04-04 14:42:12 2022-07-08 03:08:12 2019-07-11 15:17:49 2015 0 0 str. 145-154 št. 3 Letn. 48 aug. 2015 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1318-5454 631 610909 7463443 10.1515/orga-2015-0017 1318-5454 URN:SI:UM:DK:9QJRIYSF Organizacija_2015_Rozman,_Kljajic,_Pazek_Sugar_Beet_Production_A_System_Dynamics_Model_and_Economic_Analysis.pdf Organizacija_2015_Rozman,_Kljajic,_Pazek_Sugar_Beet_Production_A_System_Dynamics_Model_and_Economic_Analysis.pdf 1 D70E12A0BDF433251543083CF70637AF c2c9852e2263df22764557463958eddf556164eeb4921ea3ff07b0d5a6d148c1 1048d0a5-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=110604 http://www.degruyter.com/view/j/orga.2015.48.issue-3/orga-2015-0017/orga-2015-0017.xml 1 https://dk.um.si/Dokument.php?lang=slv&id=110603 Fakulteta za kmetijstvo in biosistemske vede Organizacija 0 0 0
