بورس کالای زعفران مانند هر بازار دیگری، همیشه با محدودیتها و مسائل ساختاری روبرو بوده است و بخش عمدهای از این مشکلات مربوط به نوسانات قیمتی آن است. پیشبینی قیمت با استفاده از الگوهای مناسب میتواند کمک زیادی به کاهش ریسک قیمتی بازار آتی زعفران کند. سوال اساسی این است که در مواجهه با روشهای متعدد پیشبینی قیمت، برای پیشبینی قیمت آتی زعفران کدام روشها را باید انتخاب کرد؟ هدف از مطالعه حاضر، طراحی مناسبترین مدل هیبریدی برای پیشبینی قیمت آتی زعفران نگین در بورس کالای کشاورزی است که از مجموعه مدلهای غیرخطی الگوریتم ژنتیک، شبکه عصبی عمیق، جنگلی تصادفی، ماشین بردار پشتیان و روش مونتکارلو تشکیل شده است. در این مدل هیبریدی از الگوریتم ژنتیک برای تعیین وقفه بهینه سری زمانی قیمت، از شبکه عصبی عمیق، مدل جنگلی تصادفی و ماشین بردار پشتیبان برای پیشبینی سری زمانی قیمت و از روش مونتکارلو برای شبیهسازی محتملترین احتمال قیمت استفاده شده است. نتایج حاصل از این مطالعه نشان داد که دقت پیشبینی مدل هیبریدی «الگوریتم ژنتیک-شبکه عصبی عمیق-مونتکارلو» بیشتر از دو مدل «الگوریتم ژنتیک-جنگلی تصادفی-مونتکارلو» و «الگوریتم ژنتیک-ماشین بردار پشتیبان-مونتکارلو» است. بنابراین، استفاده از شبکه عصبی عمیق و محاسبه محتملترین احتمال قیمت با استفاده از روش مونت کارلو دقیقترین پیشبینی قیمت زعفران با درجه اطمینان بالا و حداقل ریسک ارائه میدهد. بنابراین پیشنهاد میشود که مدیریت بورس کالاهای کشاورزی، فعالین بازار بورس، محققین و علاقهمندان فن پیشبینی از مزایای این مدل پیشنهادی در پیشبینی قیمت محصولات کشاورزی استفاده کنند.
