Quality Function deployment (QFD) is a useful method for optimizing products which can be applied during the design process as well as in the postproduction process for further developments and revisions. This paper aims at examining the applicability of QFD and Analytic Hierarchy Process (AHP) to incorporate customer expectations and design quality into the product through a case study on a ceramic washbasin (1). In the first phase of the study customer needs and satisfaction are surveyed based on the current product design. This data is then merged with a Voice of Engineer (VOE) chart where technical attributes and features corresponding to the items in the Voice of Customer (VOC) are listed. By using the Analytic Hierarchy Process (AHP), the customer needs as well as technical attributes are quantified and prioritized. Quality characteristics are then obtained by the calculation of customer weights according to the level of importance, which were then transformed into measurable technical attributes in the House of Quality (HOQ). Interrelations among customer requirements, technical attributes and planning blocks were put in a matrix in order to get precise evaluations. The findings of this study demonstrate that the application of QFD at an earlier period in the design phase can help to efficiently implement design remediation.

Missile system design and optimization integrated with system engineering methodologies Karataban, Deniz.; Kutay, Ali Türker; Department of Aerospace Engineering (2019) In the missile system design process, customer’s requirements and system design are entirely interrelated. From the beginning of the design process, customer requirements should be taken into consideration carefully to avoid an inappropriate design. Moreover, in order to handle the changes in the requirements efficiently, both the requirement’s implementation into the design and design processes should be accelerated. Within the scope of this thesis, a design optimization tool that provides solutions to the...
Unified Process Modeling with UPROM Tool Aysolmaz, Banu; Demirörs, Onur (2014-06-20) UPROM tool is a business process modeling tool designed to conduct business process and user requirements analysis in an integrated way to constitute a basis for process automation. Usually, business process models are not utilized systematically to develop related artifacts, specifically when a process-aware information system is to be developed to automate those processes. This results in completeness, consistency and maintainability problems for those artifacts. Unified business process modeling methodol...
Effective use of quality function deployment and Kansei engineering for product planning with sensory customer requirements: A plain yogurt case Dolgun, Leman Esra; Köksal, Gülser (Informa UK Limited, 2018-01-01) Product planning, as typically the first phase of quality function deployment, involves identifying customer requirements and translating them into technical requirements. Understanding true customer needs and setting targets for customer and technical requirements can be very difficult especially when sensory product characteristics such as taste, odor, and texture are concerned. In this study, effective approaches are developed and implemented for overcoming these difficulties in a plain yogurt case. A cu...
Application of genetic algorithms for calibration and verification of QUAL2E model Göktaş, Recep Kaya; Aksoy, Ayşegül (null; 2004-07-01) Traditional trial-and-error methods make the calibration and verification of a model considerably time consuming. In addition, it is doubtful whether the best results will be achieved. However, by use of optimization techniques in calibration and verification, the best kinetic parameter estimates can be obtained in a shorter time period. In this study, a genetic algorithm (GA) is used to determine the reaeration coefficients for QUAL2E. An objective function, defined by sum-of-least-squares, is used in orde...
Process Maintenance through Component-Process Replacement Manzer, Ayesha; Doğru, Ali Hikmet (2006-03-01) An enterprise is represented by its process model that is constructed by the integration of smaller processes corresponding to value-added contributors. Replacing the sub-processes can modify the super-process. Component processes are represented in task systems in order to discover how process attributes will be preserved after integration. This approach is especially versatile if virtual enterprises are formed over the Internet through integrating the published processes of core competencies. The virtuall...
