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 ...

The balanced scorecard (BSC) is a strategic management method that links performance measurement to vision and strategies using a multidimensional set of financial and non-financial performance metrics. Although several studies have combined the BSC method with multi-criteria decision analysis methodologies, most of the research efforts do not consider the essentials of strategic and performanc...

The research aims to prioritize the solutions overcome challenges of Lean Six Sigma 4.0 (LSS 4.0). It is an integrated approach with lean, six sigma, and Industry attributes. This helps achieve organizational excellence sustainable development goals. Fuzzy stepwise weight assessment ratio analysis (fuzzy-SWARA) was used estimate weights LSS challenges. Furthermore, fuzzy-weighted aggregated sum...

A b s t I' act. Maintaining soil productivity is essential if agri­ culture production systems are to be sustainable, thus soil quality is an essential issue. However, there is a paucity of tools for mea­ surement for the purpose ofunderstanding changes in soil quality. Here the possibility of using fuzzy modeling theory as a means to address the problem of soil quality assessment is considered...

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 purpose of this paper is to apply a fuzzy quality function deployment (QFD) approach to prioritize knowledge management (KM) solutions for an international port in Taiwan. First, the paper examines house of quality (HOQ) matrices to facilitate handling of the ‘what’ (i.e., KM requirements) and ‘how’ (KM solutions) aspects of the QFD problem, and proposes procedures for the use of a fuzzy QF...

investigation of reliability characteristics under fuzzy environments is proposed in this paper. fuzzy weibull distribution and lifetimes of components are using it described. formulas of a fuzzy reliability function, fuzzy hazard function and their α-cut set are presented. furthermore, the fuzzy functions of series systems and parallel systems are discussed, respectively. finally, some numeric...

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...
