Background and Purpose: The purpose of this study is to describe the principles of the development of parallel system-dynamics and agent-based models of organic farming for the case of Slovenia. The advantage of agent-based modeling is demonstrated by including geospatial information as an agent attribute. The models were compared by the validation, confirming the appropriate level of similarity. Design/Methodology/Approach: Both system-dynamics and agent-based modeling approaches were applied. Statistical methods were used in the validation. Results: The results of the validation confirm the appropriateness of the proposed agent-based model. Introducing additional attributes into the agent-based model provides an important advantage over the system-dynamics model, which serves as the paradigmatic example. Conclusion: A thorough validation and comparison of the results of the system-dynamics and agent-based models indicates the proper approach to combining the methodologies. This approach is promising, because it enables the modeling of the entire agricultural sector, taking each particular farm into account. Ozadje in namen: Namen pričujoče raziskave je opisati razvoj paralelnega modela, razvitega po principih Sistemske Dinamike in Agentnega modeliranja. Model je razvit za potrebe simulacije prehoda k ekološkemu kmetijstvu na področju Slovenije. Prednost agentnega modeliranja je bila prikazana z vključitvijo geografske informacije kot agentnega atributa. Izvedena je bila primerjava modelov. S pomočjo validacije je bila potrjena visoka stopnja podobnosti izhodnih rezultatov ter primernost pristopa. Oblikovanje/metodologija/pristop: Uporabljeni so bili principi modeliranja Sistemske Dinamike in agentnega modeliranja. Pri izvedbi validacije so bile uporabljene statistične metode. Rezultati: Rezultati validacije so potrdili primernost razvitega agentnega modela. Možnost dodajanja novih atributov v agentnem modelu zagotavlja pomembno prednost pred modeliranjem po principih sistemske dinamike, in hkrati predstavlja paradigmatski primer. Zaključek: Z izvedenim postopkom validacije in primerjavo modela razvitega po principih Sistemske Dinamike in agentnega modeliranja smo potrdili ustreznost razvitih struktur. Predlagani pristop pretvorbe modelov izkazuje ustrezen potencial za nadaljnje delo pri razvoju modela, kjer obravnavamo vsako posamezno kmetijo kot agenta z večjim naborom atributov. |
