An Integrated Design for Remanufacturing Approach

Abstract Design for remanufacturing process (DFRP) plays a key role in implementing remanufacturing because it directly affects the performance recovery of the End-of-Life (EoL) product. Since the used parts have various failure forms and defects, these make it hard to rapidly generate the remanufacturing process scheme for satisfying the performance demand of the used product. Moreover, remanufacturing process parameters are prone to conflicts during the process of implementing remanufacturing, this leads to the failure of the remanufacturing process. For accurately generating remanufacturing scheme and solving the conflicts, an integrated design method for remanufacturing process based on performance demand is proposed, which can reuse the historical remanufacturing process data for generating the remanufacturing process scheme. Firstly, for accurately describing the performance demand, the Kansei Engineering (KE) and Quality Functional Development (QFD) are applied to analyze the performance demand data and map the demand to the engineering features. Then, Back Propagation Neural Network (BPNN) is applied to inversely generate the remanufacturing process scheme rapidly for satisfying the performance demand by reusing the historical remanufacturing process data. Meanwhile, Theory of Constraint (TOC) and TRIZ are used to identify the conflicts of the remanufacturing process and resolve the conflicts for optimizing the remanufacturing process scheme. Finally, DFRP of the saddle guideway is taken as an example to demonstrate the effectiveness of the proposed method, the result shows the design method can quickly and efficiently generate the remanufacturing process for the EoL guide rail.

Cross Case Analysis

Company interest and research in the circular economy and remanufacturing have increased as a means of reducing negative environmental impacts. Remanufacturing is an industrial process whereby used products are returned to a state of like-new. However, few products are designed for remanufacturing, and further research and industrial efforts are needed to facilitate more widespread use of design for remanufacturing. One crucial factor facilitating design for remanufacturing is the integration of feedback in the product design process. Thus, the objective of this paper is to analyse feedback flows from remanufacturing to product design. Hence, a literature study and multiple case studies were conducted at three companies that design, manufacture and remanufacture different kinds of products. The cross-case analysis revealed the five barriers of the lack of internal awareness, lack of knowledge, lack of incentives, lack of feedback channels and non-supportive organisational structures, and the five enablers of business opportunities, integrated design processes, customers’ demand, laws, regulations and standards, and new technologies. To establish improved feedback from remanufacturing to product design, the barriers need to be addressed and the enablers explored. Thus, improved feedback from remanufacturing to product design will improve the design of future products suited for a more circular economy.

Practical Instruction

Recurrent training of cabin crew should include theoretical and practical instruction on safety as well as crew resource management (CRM) issues. The endeavors of Swiss International Air Lines Ltd. and Swiss Aviation Training Ltd. to integrate CRM and safety aspects into a single training module were evaluated. The objective of the integration was to make CRM more tangible and ease acquisition of competencies and transfer of CRM training content to practice by showing its relevance in relation to safety tasks. It was of interest whether the integrated design would be mirrored in a more favorable perception by the trainees as measured with a questionnaire. Participants reacted more positively to the integrated training than to stand-alone CRM training, although the integrated training was judged as being slightly more difficult and less oriented toward instructional design principles. In a range of forced-choice questions, the majority of participants opted for an integrated training format because it was seen as livelier and more interesting and also more practically relevant. For the forthcoming training cycle, a better alignment of training with instructional principles and an even higher degree of training integration by using simulator scenarios are striven for.
