D26 Checklist-based Assessment Method for Environmentally Conscious Design(Life cycle engineering and environmentally conscious manufacturing)

Abstract This paper approaches environmentally conscious design by further developing a reliability model that facilitates design for reuse. Many reliability models are not suitable for describing systems that undergo repairs performed during remanufacture and maintenance because the models do not allow the possibility of system reconfiguration. In this paper, expressions of reliability indices of a model that allows system reconfiguration are developed to enable life-cycle cost estimation for repairable systems. These reliability indices of a population of repairable systems are proven theoretically to reach steady state. The expressions of these indices at steady state are obtained to gain insight into the model behavior, and to facilitate life-cycle cost estimation.

Increasing awareness of environmental burdens has led companies and designers to initiate design for the environment (DFE) programmes, which consider the design of products from the ‘cradle to grave’ and is also known as ‘life-cycle design’. In this paper, the use of a novel environmental performance technique to be used at the early stage of product design is presented. This technique, which is to be used as a framework for green product design, is demonstrated in this paper by evaluating the environmental performance between plastic and steel fuel tanks. The fuel tank comparison can be divided into five steps. In the first four steps, a modified house of quality (HOQ) is used to analyse the performance of fuel tanks in terms of requirements of environmentally conscious design. The final step is an overall assessment that synthesizes the results from the previous four analyses. As a result, the comprehensive environmental effects in the whole life cycle of fuel tanks are captured in the early stage of design.

Environmentally Conscious Design

Abstract We have developed the Green Browser to support a team of designers to collaboratively construct and share the product life cycle information for environmentally conscious design. We developed the ReqC model (Requirement-Centered Model) and the GLC model (Green Life-Cycle Model) for structuring design information in the Green Browser. The system allows the design team to construct the GLC model by chunking discourse and assigning types. It provides a visual presentation of the concept and scenario, and allows the user outside the team to share the model across different computer environments. We used Java2 and CORBA for system implementation. To test implementation of the system, we built a GLC model by using data collected in an industrial design project.

Environmentally Conscious Design

This paper describes the outline of “life cycle design” course the author teaches and illustrates some experiences and findings with results of questionnaires to attendees of the lecture. “Life cycle design” is a half-year course to third-year students at Tokyo Metropolitan University, Japan. The main subject is environmentally conscious design focusing on life cycle thinking. This course intends to establish general and correct viewpoints toward relationship between manufacturing industry and the environmental issues, which are indispensable knowledge as mechanical engineers, rather than to educate environmental specialists. Results of questionnaires indicate that this course succeeded in increasing students’ interest in this area and awareness of importance of the environmental issues. However, some students feel bewildered because of wide variety of topics and, therefore, lack of a central theory.

Effective Design

Abstract A growing concern about the environment, and especially about waste and landfill, has motivated research into environmentally conscious design and manufacturing approaches. This has placed new burdens on designers. In order to aid designers in their new tasks, one of our objectives is to minimize the gathering of information and maximize the utility of existing design information. In the research discussed in this paper, the specific objective is to enable the quantification and enhancement of product remanufacturability. Guidelines for integrating some of the commercially available CAD packages (like I-DEAS, Pro/ENGINEER, CATIA) to remanufacturing assessments, and ways to use the input information to these assessments for making other assessments (like assemblability) are developed. A number of case studies are given to illustrate the approach. Our long term goal is to identify the minimum amount of information needed to do effective design for the life-cycle.

The Relationship

Environmentally conscious design is focused on reducing the environmental impact of engineered systems, but common practice in life cycle analysis overlooks the relationship between a product’s usage-context and its environmental performance. Existing studies rarely consider operational variability or the correlation between performance, design, and usage variables. Probabilistic graphical models (PGMs) provide the capability of not only evaluating uncertainty and variability of product use, but also correlating the results with the product’s features and usage context. This discussion explores the use of PGMs as a tool for evaluating operational variability in products and including the results in life cycle inventories. The tool is illustrated for environmentally conscious product design through an example study of an electric kettle.
