چکیده

اصلاحات جزء جدایی ناپذیر تحولات اقتصادی در بخش مالی می باشد که شامل شکل دهی دوباره ساختار بازار
سرمایه، نوآوری در ابزارها و محیطی با نظم جامع تر است. دو مکتب فکری غالب بر ادبیات بازار سهام، تجزیه
و تحلیل های بنیادی و تکنیکی می باشند. مسئله انتخاب پرتفوی بسیار مهم می باشد. به همین علت، این پژوهش
ارزیابی سهام، شرکت ها با استفاده از هر دو روش تجزیه و تحلیل بنیادی و تکنیکی را برگزیده و سپس به منظور
تشکیل پرتفویی که حالات مختلف ریسک و ترجیحات سرمایه گذارن را لحاظ کند، از مدل فازی ممدانی و
مدل برنامه ریزی خطی عدد صحیح ترکیبی استفاده نموده است. دلیل استفاده از سیستم فازی ممدانی، کارا
بودن آن در محیط های مبهم و استفاده از دانش انسانی و مدل برنامه ریزی خطی عدد صحیح ترکیبی، قابلیت
یافتن جواب بهینه مسئله از میان تعداد زیاد جواب موجود می باشد. نتایج ارزیابی عملکرد پرتفوی های تشکیل
شده برای سه حالت سرمایه گذار ریسک گریز، ریسک خنثی و ریسک پذیر، نشان می دهد که عملکرد پرتفوی
پیشنهادی مثبت بوده و عملکرد مناسبی را نشان می دههد، اما در مقیاسی  دقیق تر  پرتفوی تشکیل شده برای
سرمایه گذار ریسک گریز در وضعیت مطلوب تری قرار دارد

چکیده [English]

Modifications are an integrated part of economic evolution in financial section which include reforming the capital market structure, innovating in tools and an environment with more comprehensive discipline. Two dominant schools of thought in the literature on stock markets are fundamental and technical analysis. Selection the portfolio would be so important. So we use both fundamental and technical analysis to evaluate companies' stock and then in order to form a portfolio which consider different risk states and investor’s preferences utilize Mamdani Fuzzy and mixed integer linear programming model. The reasons for the use Mamdani Fuzzy system are its capability of working in vague environment and using human knowledge and for mixed integer linear programming model is its capability in finding the optimum solution among the several available ones. The results of evaluating the performance of formed portfolio for three cases of Risk averse, Risk neutral and Risk prone investor show that the performance of proposed portfolio is positive and proper, but in a more accurate scale the formed portfolio has a more proper condition for the risk averse investor.
