Quality function deployment (QFD) is a systematic process for translating customer needs into engineering characteristics, and then communicating them throughout the enterprise in a way to ensure that details are quantified and controlled. The inherent fuzziness of relationships in QFD modeling justifies the use of fuzzy regression for estimating the relationships between both customer needs an...

In today’s competitive global markets, Just-in-Time (JIT) is one of the main lean manufacturing approaches. It is used in organizations to improve performance and reduce costs and as a strategic core capability to ensure their market position. However, using JIT tightly couples various functions of the Supply Chain and increases the risk of propagating disruptions through the entire system. Thi...

paying attention to customers is necessary for continuing operation in competitive markets today. through customers’ satisfaction, organizations can reduce production costs and increase their revenues. customer relationship management can help the managers and organizations with establishing a constructive relationship with customers and maintaining them. therefore, developing and deploying an ...

this paper is in search of designing the cellular manufacturing systems (cmss) under dynamic and flexible environment. cm is proper for small-to-medium lot production environment that helps the companies to produce variable kind of productions with at least scraps. the most important benefits of cm are decline in material handling, reduction in work-in-process, reduction in set-up time, increme...

Customer service is increasingly being recognized as a source of competitive advantage. Determining customer needs accurately, meeting and exceeding them in a consistent manner is the key to the effective customer service. Companies should adapt a strategic, proactive focus on customer service based on understanding logistics process and designing logistics system to meet their needs. This ...

Many kinds of scheduling systems have been installed for many kinds of manufacturing factories more than thirty years until now. A production scheduling system includes very important functions for production cost reduction and the improvement in customer satisfaction. However, not all systematization has been successful. Therefore, in order to realize homogeneous systematization to various kin...

abstract: an efficient supply chain system operates under a strategy to minimize costs by integrating the different functions inside the system and by meeting customer demands in time. in this paper, an integrated supply-production and distribution planning (spdp) is considered despite the fact that in most of the papers, part of the supply chain has been studied, not all parts. therefore, we d...

Due date assignment for customer orders has been studied in various productionenvironments using different modeling approaches. In this paper the researchers consider aproduction system in which the orders of several customers are produced in a single batch because ofthe economy of scale. If a batch is completed before receiving customer orders, inventory carryingcost is incurred but if it is c...

This study examines some major variables moderating the relationships of service quality, customer satisfaction, and customer loyalty in mobile phone services. The study employed statistical analyses, such as reliability analysis, factor analysis, and hierarchical regression analysis. The results of the study reveal that service quality and customer satisfaction positively affect customer loyal...
