چکیده
در سالیان اخیر با ظهور مدل‌سازی اطلاعات ساختمان (BIM) پیشرفت‌های قابل ملاحظه‌ای در تحقق مؤلفه‌های اصلی مدیریت ساخت پروژه از قبیل ایمنی، هزینه و زمان به وقوع پیوسته است. از مدل‌های مبتنی بر BIM به‌صورت گسترده جهت برنامه‌ریزی ایمنی پروژه‌ها و کنترل زمان و هزینه ساخت بهره‌برداری می‌شود. استفاده از مدل‌سازی اطلاعات ساختمان تأثیر مثبت خود را در فرایند شناسایی و حل تداخل‌ها نیز نشان داده است. در طرح‌ها و پروژه‌های بزرگ به علت تعدد عوامل درگیر در طراحی‌ها و همچنین پیچیدگی و حجم بالای المان‌ها تعداد بسیار زیادی از تداخل‌ها بین المان‌های مختلف در فرایند ادغام یکپارچه طراحی‌ها اتفاق می‌افتد که بدون به‌کارگیری ابزارهای مدل‌سازی اطلاعات ساختمان شناسایی و رفع آنها بسیار وقت‌گیر و پیچیده می‌باشد. تداخل‌ها درصورتی‌که در مرحله طراحی، به‌دقت شناسایی و حل نشوند ضمن افزایش حجم کاری، مدیریت ایمنی، زمان و هزینه پروژه را به خطر می‌اندازند. در میان عناصر ساختاری مختلف، تداخل‌های طراحی المان‌های مکانیکی، تأسیسات الکتریکی و لوله‌کشی (MEP) به‌طور مرسوم فرآیند طراحی را تحت تأثیر قرار داده ‌است که شاید به دلیل فضاهای محدود برای سیستم‌های MEP باشد. هدف این تحقیق گروه‌بندی المان‌های MEP، جهت تعیین اولویت آنها از منظر زمان و هزینه در فرآیند رفع تداخل‌ها می‌باشد. به همین منظور این تحقیق با استفاده از روش دلفی نسبت به گروه‌بندی المان‌های MEP اقدام و سپس روش فازی – سلسله مراتبی را جهت تعیین وزن المان‌های MEP به‌کارگیری می‌نماید.

چکیده English

In recent years, with the advent of building information modeling (BIM), significant progress has been
made in the quality of the designs and execution of projects. BIM-based models are widely applied to
project safety planning and control of time and cost in construction projects. The use of Building
Information Modeling has also shown a positive influence on process of clash detection and clash
resolution. During the design stages, BIM drawings and plans produced by individual designers are
integrated into a federated model and tested to detect design clashes, which if they are not carefully
detected and resolved in the design phase, they risk the safety, time, and cost of the project management
in addition to increasing the workload. Because of the confined spaces left for MEP systems, between the
various elements, mechanical, electrical and plumbing (MEP) design clashes have traditionally dogged
the design process. The purpose of this study is to grouping MEP elements to determine their priority in
terms of time and cost in the clash resolution process. This research uses the Delphi method to group
MEP elements and then applied the Fuzzy-AHP method to determine the weight of MEP elements.
