Abstract: Traditional Turkish coffee brewing method has a history of five hundred years, new gadgets which were the rivals of the ibrik, had been designed to meet the ‘need of speed’, which was the requirement of the era. In this study the history of coffee and the Turkish coffee brewing methods was mentioned. Then three Turkish coffee brewing machines which were chosen from the market was examined according to the level of their customer requirement satisfaction by using (QFD) quality function deployment method. After evaluating the datas obtained from this examination, findings were argued and suggestions were made about which specifications of the products should have been developed in the next generation design of the products.

Abstract: This article studies the resolution of problems related to the design of complex products using a systems engineering approach. We illustrate our discussion with a case study from the space sector pertaining to the design of microsatellites. We postulate that problem complexity depends on the nature of the interaction between product subsystems, as well as on the difficulty of defining an acceptable formulation of the problem by the project team. Our analysis tends to show that although systems engineering is effective for breaking a product into subsystems and managing the resulting issues, it is sometimes inefficient to deal with problems that are difficult to formulate. This is because systems engineering does not explicitly take into account the technical, organizational and cognitive contradictions inherent in the most innovative design problems.

Abstract: The company's ability in developing new products is a crucial factor in its commercial success which mostly relies on partner’s performance too. These partners by their needed and asked contribution become an integrated part of the industrial strategy. The partner selection task is therefore a more and more risky one because companies have to take account of diversified and complex selection criteria. Consequently, the selection criteria should be structured in order to be feasible for an efficient partner selection. In this paper, we present a methodology for selecting partners, and we use the partners’ classification as the main driver of criteria structure. This idea is illustrated through its application to a set of selection criteria taken from the scientific literature.

Abstract: Nowadays, PLM systems take a major place in the product development process. PLM implementation through IT environment is a key strategy for collaborative definition and management of product data and knowledge. In order to improve product cost and quality, to reduce time to market, companies and their partners need to exchange and share their data effectively. The aim of the paper is to provide a literature review of research works developed for data and information exchange and sharing between CAD and CAE systems such as implemented in the current PLM strategy. Then, the paper proposes a survey of data exchange protocols and standards. Finally, a more comprehensive approach for software interoperability and data exchange and sharing will be developed.

Abstract: This paper presents a geometrical model that uses points and line segments to describe mechanisms at the early phases of the product design process. This model allows the description of an object with a topological matrix and another matrix that contains the metric information about the object. The paper also indicates how to associate two objects represented using this model. Finally, the interest of this model for the mapping of a geometrical requirement along the product life-cycle is shown on a case study.
