Abstract

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.
