    Mismatch Between Classroom Furniture and Student Body Dimensions: Case of İzmir
    (2019) Kaya, Nazife Aslı; Erkarslan, Önder; Erkarslan, Önder; 02.04. Department of Industrial Design; 02. Faculty of Architecture; 01. Izmir Institute of Technology
    The aim of the research is to determine the anthropometric measures of school children aged 12-13, who live in Izmir, Turkey, in order to propose anthropometrically appropriate school furniture (desk and chair), and to compare findings with the available classroom furniture produced according to Standards of Classroom Furniture, published by Republic Of Turkey General Directorate of Primary Education to determine potential mismatches. A total of twelve anthropometric data were collected by convenience sampling from 393 (207 male and 186 female) students. The data were analyzed with the aid of the SPSS v13 software on a desktop computer. Descriptive statistics for each anthropometric dimension are given as mean, standard deviation and 5th and 95th percentile values for male and female in mm. The obtained anthropometric data used for calculating classroom furniture dimensions, sitting height, seat depth, seat width, backrest height and desk height. Mismatches were found when the findings were compared with the Standards of Classroom Furniture, published by Republic Of Turkey General Directorate of Primary Education.

    Optimization of Product Design Through Quality Function Deployment and Analytical Hierarchy Process: Case Study of a Ceramic Washbasin
    (Middle East Technical University, 2011) Erkarslan, Önder; Erkarslan, Önder; 02.04. Department of Industrial Design; 02. Faculty of Architecture; 01. Izmir Institute of Technology
    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.
