Quality function deployment (QFD) is a customer-driven approach, widely used to develop or process new product to maximize customer satisfaction. Last researches used linear physical programming (LPP) procedure to optimize QFD; however, QFD issue involved uncertainties, or fuzziness, which requires taking them into account for more realistic study. In this paper, a set of fuzzy data is used to ...

For decades, Fuzzy Sets Theory (FST) has been consistently developed, and its use spread across multiple disciplines. In this process of knowledge transfer, fuzzy applications have experienced great diffusion. Among them, Analytic Hierarchy Process (fuzzy AHP) is one the most widely used methodologies today. This study performs a systematic review following PRISMA statement addresses bibliometr...

The COVID-19 pandemic broke out and the global logistics industry suffered severe losses; therefore, Fuzzy FMEA-AHP (Fuzzy Failure Mode Effects Analysis-Analytic Hierarchy Process) method is proposed to analyze failure reasons of system in pandemic. In this article, we have made an optimization on basis FMEA method: fuzzy integrated into algorithm, referred as F-RPWN (fuzzy risk priority-weight...

the main purpose of this paper is to present a fuzzy multi-criteria decision making (fmadm) model for appropriate location selection of a health center. therefore, we identify sixteen criteria and sub-criteria for selecting a health center location. these criteria and sub-criteria have been obtained from literature reviews and practical interviews. this paper proposes a method which combines th...

Researchers and academics are interested in this study because it aims to understand the factors sub-factors that affect selection of Halal products. The researcher was unaware any prior research or studies conducted ascertain how much consumers consider influencing their decision purchase products rate those variables. This paper identify rank top consumers' decisions select Perlis. Through us...

There are a number of decision making problems in which Geographical Information System (GIS) has employed to organize and facilitate the procedure of analyzing the problem. These GIS-based decision problems which typically include a number of different criteria and alternatives are generally analyzed by Multicriteria Decision Analysis (MCDA).Different locations within a geographical area repre...

-This study presents an evaluation model for purchasing life insurance and annuity insurance using analytical hierarchy process (AHP) and fuzzy logic. Four factors are considered as the inputs of the proposed model including age, annual income, educational level and risk preference. To build the model, we interviewed five experts with at least three years of working experience in an insurance c...

The objective of this article is to develop an empirically based framework for formulating and selecting a vendor in supply chain. This study applies the fuzzy set theory to evaluate the vendor selection decision. Applying Analytic Hierarchy Process (AHP) in obtaining criteria weights and applied Technique for Order Performance by Similarity to Idea Solution (TOPSIS) for obtaining final ranking...

In this article, by using fuzzy AHP and TOPSIS technique we propose a new method for project selection problem. After reviewing four common methods of comparing alternatives investment (net present value, rate of return, benefit cost analysis and payback period) we use them as criteria in AHP tree. In this methodology by utilizing improved Analytical Hierarchy Process by Fuzzy set theory, first...
