Development and analysis of design for environment oriented design parameters

Knowledge of customer requirements (CRs) allows manufacturers to effectively reduce the time-to-market for products and maintain a high-level of quality through customer satisfaction. Acquisition, definition, and decomposition of such requirements is therefore a first step in the product design process and key for successful product development. Of building importance in these requirements is for sustainable or green products. Thus has developed the method of Design for Environment (DFE) in product design process, which calls designers to not only understand CRs for product function, structure and economic attributes, but in social and environmental impacts. Thus, the need for elicit environmental customer requirements (ECRs) from various traditional CRs becomes apparent along with the need to meet those requirements in the design process.In the present paper, initial CRs are decomposed and categorized into functional customer requirements (FCRs), performance customer requirements (PCRs) and ECRs. Such an analysis is made based on the analysis of environmentally friendly products (EFPs), environmentally conscious customers, and the characteristics of their CRs, Furthermore, the decomposing method based on semantic analysis is given along with a developed quality function deployment for environment (QFDE) method. These methods create a shift from initial CRs to DFE oriented technical parameters (TPs). Finally, the acquisition and conversion of CRs of the automatic soybean milk maker in the DFE process is taken as an example to validate and analyze the above-mentioned method.
