چکیده مقاله :
يکي از زمينه هايي که تحقيقات بسياري در حوزه آن صورت گرفته است مسايل مالي و بخصوص پورتفوليو مي باشد. هدف اين تحقيق بهينه سازي انتخاب پورتفوليو بگونه اي است که نه تنها با شرايط محيطي انطباق بيشتري داشته باشد، بلکه به نتايج بهتري نسبت به متدهاي قبل دست يابد. در اين تحقيق مساله انتخاب پورتفوليو با بازگشت سرمايه اي که بصورت متغيرهاي تصادفي فازي مي باشد بررسي مي گردد. چون حل چنين مدلهايي با روشهاي سنتي ميسر نمي باشد، لذا يک الگوريتم هيبريدي براي حل مساله ارائه شده است. براي اجراي روش هيبريدي ابتدا با استفاده از شبکه هاي عصبي فازي جواب موجه اوليه بدست آمده و سپس با رويکرد الگوريتم ژنتيک جواب بهينه محاسبه گرديد.
