Nowadays, industries face very strong challenges because of the high competitiveness between them. In fact, they are required to offer products with high quality and minimum cost in the minimum time. Since most of the characteristics and costs of the product and its manufacturing process are fixed in the design phase, this paper is focused on this strategic phase. Indeed, a new integrated product design approach is presented. It considers at the same time design requirements, materials characteristics, manufacturing parameters and the assembly process specifications. The developed approach is quantitative. Actually, the decision making is based on all its steps on objective and subjective indicators. To validate the integrated approach, a case study on the Schrader Robot is developed. This application allows to choose the most appropriate materials, manufacturing processes and assembly solution of its different components.

Design Characteristics

Abstract In multistage manufacturing systems, quality of final products is strongly affected not only by product design characteristics but also by key process design characteristics. However, historically, tolerance research has primarily focused on allocating tolerances based on product design characteristics for each component. Currently, there is no analytical approach for multistage manufacturing processes to optimally allocate tolerances to integrate product and process characteristics at minimum cost. One of the major obstacles is that the relationship between tolerances of process and product characteristics is not well understood and modeled. Under this motivation, this paper aims at presenting a framework addressing the process-oriented (rather than product-oriented) tolerancing technique for multistage manufacturing processes. Based on a developed state space model, tolerances of process design characteristics at each fabrication stage are related to the quality of final product. All key elements in the framework are described and then derived for a multistage assembly process. An industrial case study is used to illustrate the proposed approach.

Selection Of

Smartphones were launched in the market as a product in the early 2000’s. Today, less than 20 years later, the smartphone has become one of the most frequently used devices for human contact. The market is saturated, and competition between products has intensified, and it is not difficult to find products that are culled. To be selected by consumers, product differentiation must be outstanding, which is not easy when the basic technology is standardized. Currently, competition in the fields of cameras and displays is intensifying, but it is expected that advanced technology will become commonplace in the near future. There are several ways to increase the competitiveness and differentiation of a product, for example, by considering the technical aspects, or making the personality of the product unique. Consumers communicate with products through materials. The process and selection of materials suitable for the design requirements of a product is a very important component in competitive product manufacturing. The final material selection is performed by dividing the design requirements into function, constraints, personality, objectives, and supporting information aspects, and the selecting materials suitable for each stage. By capturing the overall concept as a function, the processes of selecting materials that meet the constraints, determining the type of material that matches the personality, and using the objectives to obtain the top-ranked materials, the final material suitable for all conditions can be selected by referring to supporting information from the top-ranked materials.

Product design-oriented models are a decision-making problem with multiple criteria based on the assessment of product design factor that represent engineer judgments and customer desires, and are used to adapt to increasing competition and high levels of customization. Thus, in this work, a “sandwich-like” architecture and a hybrid integrated approach including triangle fuzzy numbers, quality function deployment, and the LeaderRank algorithm are respectively proposed to express and assess product designs more effectively. Additionally, the proposed approach is a measure study which can determine the design requirements, the relationships between product design and customer requirements, and the correlations among product values. The fuzzy analytical network process and LeaderRank algorithm are employed to evaluate the product design requirements and interaction between the product value and the uncertainty that exists in expert judgment. Besides, a case study is selected as an example to illustrate the “sandwich-like” architecture in the product design stage, and a priority analysis is performed to assess the importance degrees of product designs for customer needs, thereby providing optimization for product design and an effective approach to improve the product value.

The Impact

With an industrial era characterized by new regulations aiming at protecting costumers and the global environment, manufacturers have to be more effective in delivering products that meet customers requirement but also, they have to be apt to dispose of the products properly whenever customers decide to return them. The traditional role of material selection and process design are challenged to take these issues into consideration and provide more effective solutions for the entire (closed-loop) supply chain. We aim at studying the impact of material and process selection decisions in the design of the reverse supply chain. We present an integrated approach that consolidates these design frameworks, and also a total cost approach to be used to set products end of life management decisions.

An integrated approach to product and process design and development based on Life Cycle Engineering principles is proposed. The aim is to make available a structured framework to drive the design team in their discussions and analysis towards the creation of purposeful design concepts and process alternatives and in their global evaluations towards informed decisions on a life cycle perspective. A case study is presented based on a cloths peg already in the market, which is intended to be redesigned in order to reduce its cost and increase its attractiveness. The simplicity of the product allows giving emphasis to the models and its methods. Considering several design and process alternatives, it is revealed how the proposed approach is applied and the type of conclusions and findings of such type of methodology.

Concurrent engineering and integrated design have been a major issue over the past two decades especially considering design for X stakes. This paper describes a new proposal of integrated product-process design approach in order to improve the efficiency and the robustness of the assembly process planning phase. The proposed method illustrates how to consider functional requirements and technical constraints as early as possible to improve design principles and define the best assembly sequences fulfilling these requirements. Lastly, the proposed research is applied on an aeronautic case study for illustrating the potential benefits of such an approach in terms of taking account of assembly knowledge in the early product development stages.

Current architecture studios are missing an important phase in the education process, which is constructing the students’ conceptual ideas on a real physical scale. The design-build approach enables the students to test their ideas, theories, material selection, construction methods, environmental constraints, simulation results, level of space functionality and other important aspects when used by real target clients in an existing context. This paper aims to highlight the importance of using the design-build method through discussing a design project case study carried out by the Masters of Architecture design programme students at Beirut Arab University, who have built prototype units for refugees on a 1:1 scale.

Abstract The difficulties in identifying the precise defect location and real leakage path is increasing as the integrated circuit design and process have become more and more complicated in nano scale technology node. Most of the defects causing chip leakage are detectable with only one of the FA (Failure Analysis) tools such as LCD (Liquid Crystal Detection) or PEM (Photon Emission Microscope). However, due to marginality of process-design interaction some defects are often not detectable with only one FA tool [1][2]. This paper present an example of an abnormal power consumption process-design interaction related defect which could only be detected with more advanced FA tools.
