“…The Lean Design-for-eXcellence framework (LeanDfX) was developed at INEGI (Institute of Science and Innovation in Mechanical and Industrial Engineering) as a comprehensive and multidimensional approach for assessing the performance of product or system designs (Atilano et al 2019;Baptista, Peixoto, et al 2018;Baptista, Lourenço, et al 2018). The LeanDfX framework encompasses multiple design domains or "X dimensions", including design for manufacturing, assembly, maintenance, modularity, adaptability, sustainability, and structural optimization, among others.…”

A comprehensive crashworthiness analysis in the design of coaches, specifically focusing on adapting the ECE R29 standard, was made. The external fiberglass composite panels of two coach models were tested for replacement with a state-of-the-art polymer (DCPD). The analysis was based on the finite element method, using the software Pamcrash®, which evaluates the energy absorption capacity of the models, comparing deformation, displacements, and material penetration values over time. The assessment of the driver's residual space, as specified by the ECE R29 standard, is also included in the analysis. The Lean Design for eXcellence (LeanDfX) methodology was used, which involves multiple domains of analysis including model optimization, manufacturing process, and eco-design. It employs an index on a 0%-100% scale, to compare different 'X' domains, such as energy absorption capacity and material intrusion. An Eco-Design X study is also conducted to assess the environmental impacts of the proposed solution compared to the original models. Quantification is carried out using the Simapro v9.2.0.2 software with the ReCiPe 2016 methodology. The modifications proposed to the coach models are shown to result in significant improvement in the structural behaviour of the vehicle for driver's physical integrity in frontal impact scenarios. The cross results of Design-for-Crashworthiness and Design-for-Eco-Design using the LeanDfX framework provide a new perspective to be integrated in the automotive industry. The use of a state-of-the-art polymer (DCPD) for the external panels, is expected to lead to a more crashworthy and environmentally friendly design for coaches, while ensuring passenger safety.

“…Design for X is an approach that aims to ensure specific requirements (within the "X" domain) for the product starting from the design phase. Design is a fundamental phase in the life-cycle of a product or service and the adoption of Design for X approaches and guidelines can really contribute to the implementation of CE [104,[133][134][135]. More precisely, the "X" domain represents a specific activity, feature or goal that must be considered in advance, during the design phase, to proactively manage the issues that may become problems in the subsequent production phases [136][137][138].…”

Overcoming the Main Barriers of Circular Economy Implementation through a New Visualization Tool for Circular Business Models

2019

View full text Add to dashboard Cite

There is a huge gap between the broad concept of circular economy (CE) and its practical implementation in the industrial sector due to several types of barriers, which shall be led back to the lack of consistent and precise information about resources, products, and processes. Without a proper information flow, it is impossible to quantify circular initiatives, both in comparison with the actual linear situation or with circular alternative opportunities. A proper quantification of circular initiatives allows the assessment of economic, environmental and social benefits and the preventative identification of potential barriers and relative solutions, monitoring the risk associated with circular investments and supporting the decision-making process. This paper describes a new tool to ensure the quantification of circular initiatives and the method to define it. It is a new Circular Business Model (CBM) visualization tool, which overcomes the main limitations of the existing models able to explain CE concepts but not to boost its practical implementation in industry. The new CBM visualization tool can be adopted in every industrial sector to highlight circular opportunities that are still hidden or unexploited or to select the best CE strategy. The proposed CBM visualization tool differs from the previous diagrams in two main characteristics: (i) the possibility to quantify resource flows and important indicators representing energy consumption, environmental and social impact, and (ii) the focus, which is not only on the product, but on the whole system, involving also the process, the company and the entire supply chain. The methodology to adopt and adapt the proposed model to different scales is described in detail. To provide a practical example, the model was qualitatively applied to a generic technical product to highlight its potential in the identification and quantification of circular activities.

“…There are some instances of initiatives, such as the Airbus PAMELA end of life initiative. Therefore, and due to the mentioned above, the main goal of the new Multidimensional Design Assessment Model is to integrate and validate aspects as Eco-efficiency and, Resource and Operational Efficiency in new process design definition, aligned with multi-dimensional design integration by adopting Design-for-X approaches based on Lean Thinking [10]. These core methods, that are part of the new framework, consist in the integration of innovative methodologies, namely ecoPROSYS and Multi-Layer Stream Mapping (MSM).…”

“…The Multidimensional Design Assessment Model, which encompasses the Eco-efficiency and Operational Efficiency Assessment, was developed to support decision-making process for high-complexity assembly processes in aircraft production. The methodology base roots comprise different original frameworks, namely: Lean Design-for-X approach for multidimensional design assessment [10]; and MAESTRI Efficiency Framework devoted to cross-link the assessment of eco-efficiency and efficiency in manufacturing processes [14]. All the rationale for supporting the decision-making in process design definition, integrating multiple criteria aspects and the necessary calculations for process design indicators are presented in this manuscript.…”

This manuscript presents a novel framework, the Multidimensional Design Assessment Model, which encompasses a multi-criteria approach to efficiency, eco-efficiency and costs assessment for a given design system in aeronautical industry production. The framework is established by adopting Design-for-X and Multi-Layer Stream Mapping approaches, based on Lean Thinking, for efficiency assessment and adopting modules of ecoPROSYS to eco-efficiency assessment. A real case study from aeronautical sector is given to demonstrate the approach, for the assembly of aircraft structure Horizontal Tale Plane, where different results are presented and discussed for each dimension of analysis and how improvement strategies can be designed.
