In Quality function deployment (QFD) approach, customers tend to express their needs in linguistic terms rather than exact numerical values and these generally contain vague imprecise information. To overcome this challenge use the method more effectively for complex customer-oriented design problems, paper introduces a novel intuitionistic Z-fuzzy QFD based on Chebyshev’s inequality (CI) appli...

The objective of image fusion for medical images is to combine multiple images obtained from various sources into a single image suitable for better diagnosis. Most of the state-of-the-art image fusing technique is based on nonfuzzy sets, and the fused image so obtained lags with complementary information. Intuitionistic fuzzy sets (IFS) are determined to be more suitable for civilian, and medi...

to calculate partial and total productivity of production factors in broiler farms in yazd province, 72 manufacturing units were selected based on simple random sampling method and their information and statistics were collected for one production period in the second half of 2013. to measure productivity, the cobb-douglas production function was estimated using classic and fuzzy regression met...

Logistics customer service is an important factor in the success of supply chain management. The aim of this study is to propose a novel approach for customer service management. For the improvement of logistics service operations, the proposed method integrates quality function development (QFD), fuzzy extended analytic hierarchy process (FEAHP), and multi-segment goal programming (MSGP). The ...

In this dissertation the generation and tuning of fuzzy membership function parameters are considered as a part of the fuzzy model development process. The automatic generation and tuning of fuzzy membership function parameters are needed for the fast adaptation and tuning of fuzzy models of various nonlinear dynamical systems. The developed methods are especially useful in automatic fuzzy memb...

The demand for quality software system is increasing day by day because quality defines the capability of the software systems. Software systems are root of any developing systems. They are always checked on the basis of their quality. The quality characteristics are considered as very important aspects by development of software system. The evaluation of quality also plays important role in th...

In this paper, the use of clustering algorithms for decisionlevel data fusion is proposed. Person authentication results coming from several modalities (e.g., still image, speech), are combined by using fuzzy k-means (FKM) and fuzzy vector quantization (FVQ) algorithms, and median radial basis function (MRBF) network. The quality measure of the modalities data is used for fuzzification. Two mod...
