چکیده

امروزه اجرای پروژه برای تحرک و پویایی و توسعه و همچنین برای ضمانت بقای سازمان‌ها ضروری است. از آنجا که محیط همواره در حال تغییر است لذا به دلیل مطالبات مشتریان و هم‌زمان با افزایش پیچیدگی پروژه‎های صنعتی رشد مفاهیم کیفیت نیز مورد توجه قرار گرفته است. این مقاله بر تحلیل ویژگی‎های کلیدی کیفیت در پروژه‎های خطوط انتقال گاز با استفاده از مدل‎سازی معادلات ساختاری گاز متمرکز شده است و قادر می‎سازد تا یک روش در بهبود کیفیت ساخت در این نوع پروژه‎ها صورت گیرد. در این راستا ویژگی‎های (سازه‎های) کیفیت استخراج شده از تحقیق در6 عنصر با کیفیت‎ترین پروژه؛ بی‎کیفیت‎ترین پروژه؛ پروژه با کیفیت بالا؛ پروژه با کیفیت پایین؛ پروژه با کیفیت؛ پروژه با کیفیت ایده آل و با استفاده از ابزار تحلیل آماری لیزرل  بر روی داده‌های پژوهش، تحلیل عاملی تأییدی انجام گرفت و با استفاده از اس پی اس اس   سازه‌های کیفیت طبقه‎بندی شد. در ادامه با استفاده از مدل‌سازی معادلات ساختاری سازگاری کل مدل مفهومی مورد برازش قرار گرفت. با توجه به تفسیر نتایج کلیه سازه‌ها تأثیر معناداری بر کیفیت پروژه‌های انتقال گاز دارند همچنین از مدل‎سازی معادلات ساختاری و بار عاملی، نمایندگان طبقات شامل ویژگی‎های تأمین ‎الزامات، یکپارچگی، انعطاف‎پذیری، تخصص گرایی، پیوستگی، کم‎مصرفی، آینده‎نگری، کفایت اسناد و مدارک، تکنولوژی گرایی، انطباق با استاندارد، نظارت و کنترل مؤثر و زیبایی‌ معماری تأسیسات، انتخاب گردیدند. پرواضح است که برای رسیدن به کیفیت مطلوب در اجرای پروژه‎ها توجه به این ویژگی‎ها مفید می‎باشد گرچه توجه به همه سازه‎ها می‎تواند منجر به موفقیت پروژه شود.

چکیده [English]

Today, implementation of projects is necessary for organizations' mobility, dynamism and development as well as guaranteeing their survival. Since environment is constantly changing, the growth of quality concepts has also been taken into consideration due to the demands of customers and increasing complexity of industrial projects at the same time. This paper focuses on analyzing the key attributes of quality in gas transmission pipeline projects using gas structural equation modeling enabling a method to improve construction quality of this type of projects. In this regard, attributes (constructs) of quality extracted from research were classified into 6 elements of the highest quality project, least quality project, high quality project, low quality project, medium quality project, ideal quality project using LISREL statistical analysis tool and then the adaptability of the whole conceptual model was fitted. According to the interpretation of the results from structural equation modeling and factor loading, the representatives of the 6 classes including attributes of requirement consideration, integration, flexibility, specialism, continuity, normally(consumption energy), foresight, good documentation, technology oriented, conformance to standards, effective supervision and nice were selected. It is clear that considering these attributes is essential to achieve the desired quality in project implementation. Although, regarding all constructs can lead to success of the project.
