Product Design Process

In the current, highly competitive marketplace, customer demand is a major factor in the product design process. Most firms make an effort to indicate that their products differ from the competitors' products. The purpose of this paper is to understand customers' expectations of and technical requirements for e-stores and to evaluate most popular e-stores in Turkey (i.e., ES1, ES2, ES3). In this study, the authors aim to understand the customer expectations and technical requirements by using quality function deployment (QFD). To prepare the house of quality (HoQ), the authors surveyed 20 experts who are customers who have elite membership (their expenses for these e-stores are more than regular customers and have elite cards) of the three e-stores and academicians. After creating the HoQ, the authors employ fuzzy linear regression to evaluate the relationships between customer expectations and technical requirements and among technical requirements themselves. Finally, the authors use zero-one goal programming (ZOGP) to select the most desirable e-store.

Desain jasa bertujuan agar jasa yang ditawarkan dapat memenuhi harapan pelanggan. Salah satu alat yang dapat digunakan dalam desain jasa adalah Quality Function Deploy Service design is intended so that the services offered can meet customer expectations. One of the tools that can be used in service design is Quality Function Deployment with the House of Quality, which connects customer desires and the company's ability to respond to them, besides knowing the company's position in competition. The study population are all customers of PT. X and its competitors with 115 people as samples through purposive sampling. Results show PT. X has not been able to fulfill customer wants or needs properly, seen from the gap between level of interest and the level of company performance. There are 7 service indicators that become customer needs or customer requirements and 7 technical requirements, although the difference is not that far, position of PT. X is still below its competitors and needs improvement to increase customer satisfaction. Keywords: Design services, QFD, House of Quality ment dengan House of Quality, yang menghubungkan keinginan pelanggan dan kemampuan perusahaan dalam menanggapinya, selain itu dapat mengetahui posisi perusahaan dalam persaingan. Populasi penelitian adalah seluruh pelanggan PT. X dan pesaingnya dengan sampel sebanyak 115 responden menggunakan purposive sampling. Hasil menunjukkan PT. X belum mampu memenuhi keinginan atau kebutuhan pelanggan dengan baik dilihat dari adanya gap antara tingkat kepentingan dengan tingkat kinerja perusahaan. Terdapat 7 indikator pelayanan jasa yang menjadi kebutuhan pelanggan atau customer requirement dan 7 technical requirement, walaupun perbedaanya tidak jauh namun posisi PT. X masih dibawah pesaingnya dan membutuhkan perbaikan untuk meningkatkan kepuasan pelanggan.

AbstractA design problem with deficient information is generally described as wicked or ill-defined. The information insufficiency leaves designers with loose settings, free environments, and a lack of strict boundaries, which provides them with more opportunities to facilitate innovation. Therefore, to capture the opportunity behind the uncertainty of a design problem, this study models an innovative design as a composite solving process, where the problem is clarified and resolved from fuzziness to satisfying solutions by interplay among design problems, knowledge, and solutions. Additionally, a triple-helix structured model for the innovative product design process is proposed based on the co-evolution of the problem, solution, and knowledge spaces, to provide designers with a distinct design strategy and method for innovative design. The three spaces interact and co-evolve through iterative mappings, including problem structuring, knowledge expansion, and solution generation. The mappings carry the information processing and decision-making activities of the design, and create the path to satisfying solutions. Finally, a case study of a reactor coolant flow distribution device is presented to demonstrate the practicability of this model and the method for innovative product design.

Design reuse is the application of past designs knowledge and successful experience to current design process and it is a significant method for rapid design. A knowledge-reuse-based rapid product design model is proposed and a three-factor product design iterative process model is studied. Finally, it is applied successfully in the rapid product design of construction machinery combining with the requirement of the construct machinery product design.

Sustainable Product

To achieve sustainable product design, it is crucial to use sustainability assessment during the product design process. In this paper, numerous sustainability assessment methodologies in product design are reviewed. A comprehensive assessment of sustainability has been reported to present better performance for improving product sustainability. This review focused on the consideration of sustainability elements by previous researchers that have proposed integrated design tools, commercial software tools and combination both methods in supporting the methodologies. Based on this review, it can be concluded that the inclusion of sustainability performance among the assessment criteria in the design process activities is suggested as a critical point of concern which presents a challenge and is a great opportunity to develop useful guidelines or directions for industries or any product-based project so that the proposed approach will be accepted for implementation in the working environment.
