Abstract Vendor Selection Problem (VSP) has been considered in this paper as an integrated method of Fuzzy Analytic Hierarchy Process (FAHP) and Quality Function Deployment (QFD) in the pharmaceutical company. In QFD method, determining the importance of the "weights" for the customer requirements is an essential and crucial issue. FAHP has been used to determine the importance of the "we...

Energy is one of the primary inputs in textile processing industries that have a significant impact on the cost of a cotton product. The energy cost-share is reported between 5-10% of the total production cost of woven cotton fabric in textile factories of developed countries. However, it is far higher in developing countries. This study aims to contribute to the understanding of energy use and...

Quality function deployment (QFD) is a product development process performed to maximize customer satisfaction. In the QFD, the design requirements (DRs) affecting the product performance are primarily identified, and product performance is improved to optimize customer needs (CNs). For product development, determining the fulfillment levels of design requirements (DRs) is crucial during QFD op...

the multivariate exponentially weighted moving average (mewma) control chart is one of the best statistical control chart that are usually used to detect simultaneous small deviations on the mean of more than one cross-correlated quality characteristics. the economic design of mewma control charts involves solving a combinatorial optimization model that is composed of a nonlinear cost function ...

The paper provides a comprehensive insight into current trends and developments in Concurrent Engineering for integrated development of products and processes with the goal of completing the entire cycle in a shorter time, at lower overall cost and with fewer engineering design changes after product launch. The evolution and definition of Concurrent Engineering are addressed first, followed by ...

Introduction Quality of the software product and process affects the competitive position of the business organization and the role of the IS function within the organization[1]. Information systems (IS) departments are under increased pressure to deliver operational systems on-time[2]. Poor quality systems consume additional resources and contribute to the twoto three-year backlog of developme...

This paper examines the impact of variation in production volume on product cost, as estimated by three different costing systems. Production volumes were categorized as being small, medium or large. A Traditional (volume based) Cost Accounting System (TCA), an Activity-Based Costing System (ABC), and an Integrated Activity-Based Costing and Economic Value Added System (Integrated ABC-and-EVA) ...

Activity-based costing (ABC) system more precisely allocates the overhead costs to cost objects (products, services or customers) than traditional costing systems. In ABC, resources are consumed by the activities, and multiple cost drivers are used to allocate the costs of activities to the products. The selection of activity and cost drivers is then highly significant. Using too few cost drive...
