ملخص المقالة :
هدف اصلی این مقاله تعیین عوامل تاثیرگذار در انتخاب اندازه بافرها با توجه به ریسکهای پروژه است که همواره این عوامل به دلیل آنکه حسی و شهودی هستند، دقیق محاسبه نمیشوند و همچنین به دلیل کمبود منابع و زمان موجب تاخیر در پروژه شده و یا بیشتر از نیاز واقعی فعالیتهای پروژه در نظر گرفته میشوند که این امر هزینههای پروژه را افزایش میدهد. از طرف دیگر در این مقاله سعی شده تا روابط و تعامل ریسکها با یکدیگر شناسایی شده و در قالبِ مدلی مفهومی ارائه گردد. در مدل ارایه شده ریسکهای پیشران و وابسته تعیین خواهند شد که در بستر مدل مفهومی ارائه شده می توان با مدیریت ریسک های پیشران بر اندازه بافرهای کل پروژه تأثیر گذاشته و شاخص های زمانی و هزینه ای پروژه را در حد قابل قبولی بهبود ببخشد. به منظور ارائه مدل مفهومی از روش مدلسازی ساختاری تفسیری (ISM) استفاده شده است و برای فراهم ساختن اطلاعات کیفی مدل مصاحبه های عمیق با بیست و هفت نفر از خبرگان و مدیران پروژه های بزرگ در حوزه نفت و گاز انجام شده است. بر اساس مدل مفهومی ارایه شده و همینطور تحلیل همزمان، مشکلات ناشی از پیچیدگی و شناخت کم از مسایل فنی پروژه عاملِ اصلی است که باعث می شود مدیران و پیمانکاران مجبور به افزایش سطح بافرها شوند.
