چکیده
هدف: هدف از انجام این پژوهش برآورد قیمت بازیکنان لیگ برتر فوتبال ایران بود.
روش: روش تحقیق، آمیخته اکتشافی و ترکیبی از روش‌های کیفی و کمی بود. جامعه آماری پژوهش در بخش کیفی شامل مدیران، مربیان باشگاه‌ها و کارشناسان آشنا به حوزه بازار بازیکنان فوتبال بودند که چهارده نفر از آنها به‌روش گلوله برفی تا رسیدن به اشباع نظری انتخاب شدند. ابزار تحقیق در بخش کیفی شامل مصاحبه عمیق بود که پایایی آن با روش باز‌آزمایی 81 درصد محاسبه شد. در بخش کمی، جامعه آماری کلیه بازیکنان لیگ حرفه‌ای فوتبال ایران طی سال‌های 99-1395 بودند که با روش نمونه‌گیری در دسترس، ۸۶۳ بازیکن انتخاب شدند. داده‌ها از سایت‌های معتبر و سازمان لیگ فوتبال ایران جمع آوری شد. همچنین این مدل از طریق شبکه‌های عصبی شعاعی با استفاده از نرم‌افزار SPSS و R طراحی شد.
یافته‌ها: بخش کیفی نشان داد که عملکرد بازیکن، ویژگی‌ها و توانایی‌های فردی، ویژگی‌های باشگاهی و عوامل حباب‌ساز در تعیین قیمت بازیکنان فوتبال مؤثر است. در قسمت کمی مدلی با سه لایه مخفی طراحی شد که کمترین میزان خطا را در پیش بینی قیمت بازیکنان داشت.
اصالت و ابتکار مقاله: امروزه یکی از مشکلات اساسی در زمینه نقل و انتقالات در لیگ های فوتبال کم بودن معیارهای مناسب برای قیمت گذاری بازیکنان است. هدف از این مطالعه برآورد قیمت بازیکنان حرفه ای فوتبال با استفاده از شبکه‌های عصبی مصنوعی است.
