چکیده
ارزیابی مفهوم طراحی به دلیل اینکه در اولین مرحله طراحی محصول مسیر فعالیت‌ها را مشخص می‌کند، به عنوان یکی از فازهای اصلی در توسعه تولید محصول شناخته شده است. با این حال، معمولاً در این مرحله اطلاعات سلیقه‌ای و ذهنی بوده و به قضاوت کارشناسان بستگی دارد. چگونگی کنترل و مدیریت این ابهامات فردی مسئله مهمی به حساب می‌آید. از اینرو، این پژوهش یک روش نظام‌مند ارزیابی را ارائه می‌دهد که بر اساس یکپارچه کردن فرایند تحلیل سلسله‌مراتبی و روش رتبه‌بندی نزدیکی نسبی به راه حل ایده‌آل که به عنوان روش تاپسیس شناخته شده، بنا نهاده شده و در آنها از اعداد راف استفاده می‌گردد که مفهوم طراحی را در یک محیط ذهنی مورد ارزیابی قرار می‌دهد. در این تحقیق از اعداد راف برای معرفی ارجحیت‌ها و قضاوت‌های ذهنی افراد در فرایند سلسله مراتبی استفاده می‌شود. سپس، یک عدد راف بهبود یافته نیز توسط روش تاپسیس ارائه می‌گردد تا گزینه‌ها را رتبه‌بندی نماید. برای نمایش اعتبار و اثربخشی روش پیشنهادی، این روش در شرکت تولیدی و پخش لوازم آرایشی بهداشتی یونیلیور و برای طراحی پودر لباسشویی فوق کنسانتره اُمو اجرا می‌شود تا نشان دهد که روش پیشنهادی می‌تواند بطور موثری قطعیت در ارزیابی مفهوم طراحی را در شرایط عدم قطعیت افزایش دهد.

چکیده English

Evaluation of the design concept is known as one of the main phases in the development of product production because it determines the course of activities in the first stage of product design. However, usually at this stage the information is subjective and depends on the judgment of experts. How to control and manage these individual uncertainties is considered an important issue. Therefore, this research presents a systematic evaluation method based on integrating the analytic hierarchy process and the Technique of Order Preference by Similarity to Ideal Solution, which is known as the TOPSIS method, and in this article, rough numbers is used to evaluate the concept of design in a subjective environment. Rough numbers are used with the purpose of introducing the preferences and subjective judgments of people in the analytic hierarchy process. Then, an improved rough number is also provided by TOPSIS method to rank the options. To demonstrate the validity and effectiveness of the proposed method, this method is being implemented at the Unilever Cosmetics and Hygiene Company and designed to design the above-mentioned OMO concentrate washing powder to indicate that the proposed method can effectively increase the uncertainty in the assessment of the design concept under uncertainty conditions.
