چکیده

مدیریت پروژه، برنامه‌ریزی و هدایت پروژه در چهارچوب زمان، هزینه و کیفیت مشخص به‌سوی ایجاد نتایج مشخص‌ آن است. هدف از این پژوهش، توسعه مدل­ های ریاضی در موازنه زمانی، هزینه ه­ای، کیفی و ریسک پروژه­ هایی است که پارامترهای فعالیت­ های آن به‌صورت تصادفی و با اعداد خاکستری تخمین زده ‌شده‌اند. در پروژه­ ها برای انجام یک سری فعالیت­ ها به دنبال ترکیب بهینه برای زمان، هزینه و کیفیت پروژه و لحاظ ­کردن ریسک هستند؛ درحالی‌که اطلاعات در این زمینه ناکافی و محدود است. استفاده از روش پیشنهادی تحقیق یعنی لحاظ عدم ­قطعیت در داده­ های برنامه­ ریزی پروژه با اعداد خاکستری، می­ تواند راهنمایی برای مدیریت بهتر پروژه در این‌گونه شرایط باشد. برای حل این مدل، پس از به‌دست ­آوردن مدل برنامه‌ریزی خطی اعداد خاکستری، نسبت به حل آن اقدام شد. با بررسی پاسخ‌های به‌دست‌آمده، به نظر می‌رسد که با برنامه‌ریزی آرمانی امکان بهبود آن‌ها وجود دارد؛ ازاین‌رو مراحل تکمیلی با برنامه‌ریزی آرمانی برای پاسخ‌های رضایت‌بخش بهتری به‌منظور ارائه به مدیر پروژه صورت پذیرفت. برای مطالعه موردی، یک پروژه­ انتخابی در «شرکت ایران‌خودرو»، به‌طور نمونه ارائه می ­شود.

چکیده [English]

The project management is planning and conducting projects within time, cost and quality is determined towards the creation of specific results. The aim of this research was to develop mathematical models for the trade off time, cost, quality and risk of the project which parameters of its activities have been estimated randomly with grey numbers. In the projects, managers are looking for the optimal combination of time, cost and quality of the project and considering the risk, while information is limited and insufficient in this area. Using the proposed method with grey numbers can help to manage projects well in these conditions. For solving the model / methodology, the hybrid of fuzzy goal programming and grey linear planning has been predicted. By examining the responses, it seems that there is a possibility for them to be improved with goal programming; therefore, the further stages with goal programming for better satisfactory answers were presented to the project manager. For a case study, the project(s) in Iran Khodro Company is selected.
