The aim of this study is to improve the success and efficiency of the design concept evaluation and selection activity in industrial design by adapting two specialized evaluation-selection methods to the design process and comparatively demonstrating their use. The methods are called the Analytic Hierarchy Process (AHP) and the Analytic Network Process (ANP). In their application, first the main design objective is decided upon and the evaluation criteria are determined accordingly, followed by the listing of the design concept alternatives. Then the criteria's importance values as well as relations between them are investigated and evaluation of the alternatives is done according to the criteria by using the tools provided by the methods. The application presented in the article evaluates seven hand cart designs by using the two methods. First the tasks that are common in both methods, then the tasks specific to each method are explained. The general criteria to be used in the evaluation are identified and the effects of these criteria on the evaluation process are determined through interviews with designers and users participating in the study. Then the relative performance rankings of the available seven hand cart alternatives are calculated by using both methods. Numerical results are listed in a descending order to show the success levels of the design concepts, pointing to the one that received the highest overall performance. The findings obtained from two methods are comparatively interpreted.

Experience reflection modelling as a generative research method in an educational case for sustainable product design
Turhan, Senem; Doğan, Çağla (2014-01-01)
A generative research method, namely Experience Reflection Modelling (ERM), has been developed aimed at helping students explore and reflect upon design considerations for sustainability in the idea generation phase of a design process. ERM has been integrated into a product design for sustainability project as part of the design education in the Department of Industrial Design at Middle East Technical University. This paper begins by providing an overview of the generative research approach, explaining its...
Experience reflection modelling (ERM) as a generative research method and student engagement in product design at undergraduate level
Turhan, Senem; Doğan, Çağla; Department of Industrial Design (2013)
Research approaches driven by design thinking have the potential to bridge early stages of design process to idea generation phases in design education. Generative research is emerged from participatory approach which is used at early stages of design process aims to elicit user needs, experiences, expectations and preferences by using generative tools and techniques through helping non-designer participants express their thoughts, feelings, opinions effectively independent of their skills and abilities in ...
Design as a Collaborative Process A Systematic and Constructive Model for Developing Play Material for Blind Visually Impaired Preschool Children
Börekçi, Naz Ayşe Güzide Z. (2002-05-14)
This paper discusses a design process lived through, during the application of a model derived from design methodology and devised towards attaining a particular task. The task was: Designing a play system to contribute to the pre-school blind child’s development of object permanence, sense of self, and spatial concepts. The model employed was based on a systematic and constructive framework towards ensuring consciously made decisions. The paper also discusses the field-testing in play situations of the sys...

Design of experience sampling tools for reporting student experience in design education
Fındık, Nur; Şener Pedgley, Bahar; Pasman, Gert; Department of Industrial Design (2012)
Considering the continuous design activities that are performed throughout the design projects, design students go through several stages of decision makings, and sometimes they experience problematic situations in between consecutive supervisory meetings. Revealing all experiences during the discussions with supervisors, thus communicating the ideas could be sometimes difficult. In order to provide a better guidance, it is also important for supervisors to understand students’ process in between these meet...
