AbstractDe-manufacturing and re-manufacturing are fundamental technical solutions to efficiently recover value from post-use products. Disassembly in one of the most complex activities in de-manufacturing because i) the more manual it is the higher is its cost, ii) disassembly times are variable due to uncertainty of conditions of products reaching their EoL, and iii) because it is necessary to know which components to disassemble to balance the cost of disassembly. The paper proposes a methodology that finds ways of applications: it can be applied at the design stage to detect space for product design improvements, and it also represents a baseline from organizations approaching de-manufacturing for the first time. The methodology consists of four main steps, in which firstly targets components are identified, according to their environmental impact; secondly their disassembly sequence is qualitatively evaluated, and successively it is quantitatively determined via disassembly times, predicting also the status of the component at their End of Life. The aim of the methodology is reached at the fourth phase when alternative, eco-friendlier End of Life strategies are proposed, verified, and chosen.

Sustainable Product

Although products can contribute to ecosystems positively, they can cause negative environmental impacts throughout their life cycles, from obtaining raw material, production, and use, to end of life. It is reported that most negative environmental impacts are decided at early design phases, which suggests that the determination of product sustainability should be considered as early as possible, such as during the conceptual design stage, when it is still possible to modify the design concept. However, most of the existing concept evaluation methods or tools are focused on assessing the feasibility or creativity of the concepts generated, lacking the measurements of sustainability of concepts. The paper explores key factors related to sustainable design with regard to environmental impacts, and describes a set of objective measures of sustainable product design concept evaluation, namely, material, production, use, and end of life. The rationales of the four metrics are discussed, with corresponding measurements. A case study is conducted to demonstrate the use and effectiveness of the metrics for evaluating product design concepts. The paper is the first study to explore the measurement of product design sustainability focusing on the conceptual design stage. It can be used as a guideline to measure the level of sustainability of product design concepts to support designers in developing sustainable products. Most significantly, it urges the considerations of sustainability design aspects at early design phases, and also provides a new research direction in concept evaluation regarding sustainability.

Industrial and product design involves a lot of unstructured information for the generation of innovative product design ideas. However, the generation of innovative design concepts is not only time consuming but also heavily relies on the experience of product designers. Most existing systems focus mainly on the technical aspects of realizing product designs, which are inadequate to support concept generation process at the pre-design stage. In this paper, a knowledge extraction and design support system (KEDSS) is presented. The system aims at extracting key design concepts and depicting the trends of these concepts from the massive amount of unstructured design information in the open domain. A summary report, a related concept list, and concept trend graphs are produced based on the inputs of the designers' design ideas. A series of experiments have been conducted to measure the performance of the system. Moreover, the system has been successfully trial implemented as part of a public service platform for modern industrial design of injection molding machinery and equipment.

This paper aims to provide an insight to later researchers on the application of axiomatic design in the area of design for end-of-life (EOL) management. Among all life cycle stages of a product, design and development stage is the one that influences the later stages the most in terms of environmental impacts. In order to achieve sustainable product development, one of the considerations to be taken during the design stage is EOL management. EOL management process can be enhanced by utilizing a robust design method as well as an effective method for evaluating product design. Recent researches show that application of axiomatic design in the field of eco-design (especially design for EOL management) is still in a premature stage despite having a vast application area that covers the aspect of product design, manufacturing and supply chain management. Nonetheless, a case study published recently on eco-design using axiomatic approach has shown adequate feasibility and effectiveness. Therefore, design for sustainable EOL using axiomatic approach is worth further exploration.

The Cost

The cost estimate plays an important role in cost control and developing new products at the design stage. To improve the accuracy of cost estimate, we extract the feature parameters using the theory of concurrent engineering and factor analysis. Then we propose DCEM that is the model of cost estimate based on factor analysis and BP neural network. The model not only simplifies the input of BP neural network, but also avoids the coupling among the input parameters. The result shows that the model’s performance is stable and it can estimate the cost more accurate at the early product design stage.

The growing concern over environmental protection is prompting automobile manufacturers to develop products with better End-of-Life performance. Product remanufacturability is considered as an End-of-Life performance booster. Remanufacturability, that is, the easiness for remanufacturing of products depends on the technical, environmental, and economic feasibilities. The technical feasibility depends on the product design attributes that support remanufacturability. These design attributes are comprised of several sub-attributes. Moreover, the attributes are interrelated with each other. This paper develops a remanufacturability index for automobile systems based on the design attributes that affect the remanufacturability. A structural methodology of graph theory and matrix approach is applied for developing the remanufacturability index. The design attributes and their interrelations with due consideration of their structure is modelled through the graph theory. The remanufacturability directed graph (digraph) is defined; the nodes of this represent the remanufacturability enhancing design attributes, while the edges represent their degrees of interrelationships. The equivalent matrix of the digraph forms a remanufacturability function which leads to the evaluation of remanufacturability index. A higher value of the remanufacturability index indicates that the automobile system has high potential for being remanufactured. The methodology can be applied during the design stage of automobile systems to evaluate the remanufacturability that will enhance the End-of-Life performance. The observations would be helpful to automobile system designers in determining the extent to which the system can be remanufactured and in identifying the specific attributes that can be improved to enhance remanufacturability.

Abstract Virtual enterprises utilize the resources of the most capable partners for mutual benefit. This paper describes a high-level process planning and manufacturability analysis approach which increases decision support at the product design stage and reduces time to market by integrating the process of forming the virtual enterprise with design critiquing and process planning so that the designer can develop the process plan and evaluate the design with respect to the capabilities of the potential partners early in the design cycle. Alternative high-level process plans are generated based on the product design requirements, process capabilities, and plant performance measures. The manufacturability of each design-process plan combination is evaluated by estimating the cost, lead time, and expected quality of each high-level process plan.

Many conflicting issues exist between product design and manufacturing department. In the early design stage, designers often do not have enough expertise to successfully address all these issues. This results in a product design with a low level of assemblability and manufacturability. Hence, an intelligent decision support system is needed for early design stages to improve a design. This paper proposed a web-based intelligent decision support system, CBR-DFMA, connecting with a case base, database and knowledge base. Early experimental results indicate that potential design problems can be detected in advance, design expertise can be effectively disseminated and effective training is offered to designer by employing this system.

Product Recycling

Realization of successful recycling of end-of-life products greatly depends on, as well as environmentally conscious, whether the recycling process can be made economically feasible. We regard the ease of product recycling as indispensable in order to realize a feasible recycling process. In order to make products easier to recycle, it is necessary to take the ease of disassembly, processing and final treatment into consideration at the design stage. Therefore, an advanced evaluation method that can evaluate a product’s ease of recycling, with minimal prototyping and testing of the product is required at the early design stage. In answer to this, we have developed the Recyclability Evaluation Method (REM). In this paper, the theory of the method, procedure and the structure of the system are presented and a number of application examples are given.
