چکیده
امروزه، توجه به جنبههای اجتماعی و زیست محیطی علاوه بر جنبه اقتصادی باعث پررنگ شدن زنجیره تامین پایدار گشته است. از طرفی، نگرشهای مدیریتی کلان جهت سودآوری به عنوان یک جزء کلیدی در استواری صنایع مختلف از جمله تولید مرکبات مطرح است. در تحقیق حاضراز طریق یک دیدگاه سیستماتیک به بررسی تاثیر محرک سودآوری بر عوامل مرتبط با آن با استفاده از مدل پویایی سیستم تحت نگرشهای مدیریتی پرداخته شده است. بدین منظور یک مدل پویایی سیستم ارائه شده است و به منظور اعتبار سنجی، رفتار آن با مشاهدات تاریخی جمع آوری شده مقایسه شده است. تحلیل های آماری نشان دهنده تبعیت مدل شبیه سازی شده با حالت واقعی آن است. برای بررسی بیشتر شبیه سازی مونت کارلو برای متغیرهای حساس انجام شده است و در نهایت مدل پیشنهادی تحت سناریوهای مختلف اجرا و بررسی گردیده است. در دفعات مختلف شبیه سازی نشان داده شده است که سیاستهای مداخلاتی همچون تحقیق و توسعه (R&D) باعث افزایش تولید مرکبات ودیگر متغیرهای کلیدی می شود.

چکیده [English]
Todays, in addition to the economic aspect, paying attention to the social and environmental aspects has contributed to the sustainability of the supply chain. On the other hand, macro management attitudes for profitability are considered as a key component in the robustness of various industries, including citrus production. In this research, using a system dynamics approach we examine the effect of profitability on its related factors through a systematic view. For this purpose, a system dynamical model is presented and in order to validate it, its behavior is compared with historical collected observations. Statistical analysis indicates that the simulated model is adhered to its actual state. To further explore the Monte Carlo simulation is performed for sensitive variables, and finally, the proposed model is implemented under different employed scenarios. In different times of simulations have shown that several interventions such as research and development (R&D) can increase the citrus production and other key variables.
