“…Product design decisions such as material selection may cause environmental impact (Sofia et al, 2019), and, therefore, it is important to permanently ponder about design improvement in the context of the environment (Vyhmeister et al 2018). Parameter-based tools have been used to evaluate the environmental performance of companies (De Benedetto and Klemeš 2009), allowing the visualization of different scenarios.…”

In the context of life cycle assessment sustainability indicators, this article proposes a new indicator that is related to the embodied energy, in order to assess the lifespan of products based on their components. The indicator, called "potential embodied power" (PEP), considers that a nonreplaceable component with a shorter lifespan will determine the lifetime of the product. The PEP indicator can be considered as an inherent property of the product, and it can be optimized by using a material selection method based on the concept of annualized embodied energy. This indicator can be used for product design decision making, since it determines the impact of product disposal in relation to the lifespan for which the product was designed. Also, a methodology is proposed to contribute to evaluating the environmental impact caused by the energy discarded resulting from the design decisions. A case study was performed on smartphones, and the results show that the variation of factors such as module lifespan or embodied energy allows achieving a lower value of the embodied power.

“…The sustainability of the supply chain is also investigated in [13], especially in the energy sector, considering uncertain conditions and the material quality effect. Most of the research discusses multiple selection criteria, as in [14][15][16]. An analytic hierarchy process based multi-criteria model described in [14] and related to the renewable energy sector is based on the triple bottom line dimensions (social, economic and environmental).…”

“…An analytic hierarchy process based multi-criteria model described in [14] and related to the renewable energy sector is based on the triple bottom line dimensions (social, economic and environmental). A three-phase methodology is proposed in [15], using MCDM to identify the criteria list for sustainable material assessment model, while a multi-objective optimization model is proposed in [16] given the many alternatives available today that allow materials to be transformed into valuable products.…”

Disruptions in the global market are influencing value and supply chains reminding businesses and industries that variability and diversity of supply chains may be essential for surviving and sustainability. Operations management of any business has to address these challenges in order to avoid any serious interruptions in supply of materials in production industries by seeking substitute inputs. At the same time, the technological development offers new materials with similar quality properties, making thereby the substitute material search more difficult in terms of selecting appropriate materials with a level of quality which is similar enough. Another aspect in shifting can be found in more social-related reasons addressing changes in the value chains like traceability, low carbonization, and a more customer-oriented approach, because of moving towards green digital business. In this sense the intention of this work was to propose an algorithm for customizing the process of identifying appropriate materials in production by relying on existing algorithms i.e., the Ashby mapping, big data, applying algorithms of data analysis based on exclusion criteria embracing transformation paradigms, for enabling customization of the material selection process. The proposed algorithm was applied on two case examples, demonstrating that diversity of materials plays an important role in addressing customization requests from customers. Consequently, understanding and implementing a customer-centric approach in various phases of the product life cycle contributes to a better response by businesses faced with issuing customized offerings.

“…In particular, social or socioeconomic impacts have only been analyzed in a generic and conceptual manner without a systematic methodology for empirical assessment. As a result, most of studies in literature have focused on evaluating environmental impacts (Cox et al, 2014;de Jong et al, 2017;Han et al, 2013), technical feasibility (Tongpun et al, 2019;Tzanetis et al, 2017;Vyhmeister et al, 2018), and economic competitiveness (Lu, 2018;Rutten et al, 2017;Vyhmeister et al, 2018) of aviation biofuel, while none has addressed its social or socioeconomic aspects in depth, as noticed by Kamali et al (2018).…”

Derived from renewable feedstocks, aviation biofuel is generally perceived as inherently sustainable. However, its production involves a wide range of sectors and interacts with different actors in society. It is therefore important to understand and evaluate not only the environmental impacts of that process, but also its socioeconomic effects. At present, empirical studies assessing socioeconomic aspects of aviation biofuel are rare in scientific literature. The aim of this study, therefore, is to assess key effects of aviation biofuel production on employment, GDP, and trade balance. A scenarios-based Input-Output (IO) analysis was used to evaluate these socioeconomic effects, taking Brazilian aviation biofuel production to 2050 as an example. To address the uncertainty of IO analysis, we have proposed a stochastic simulation approach for the technical coefficients in the IO model. Four distinct scenarios were developed. In each, three potential combinations of technologies and feedstocks for producing aviation biofuel were evaluated: sugarcane via alcohol to jet (ATJ), macauba via hydroprocessed esters and fatty acids (HEFA), and eucalyptus via Fischer-Tropsch (FT). Among other things, we found that the production of aviation biofuel would create around 12,000-65,000 jobs, while contributing US$200-1,100 million to Brazil's GDP under different scenarios with different supply chains. The socioeconomic effects calculated deterministically were generally higher than the stochastic outcomes, which can be explained by factors such as technological learning and economic growth. Aviation biofuel production showed large positive net socioeconomic effects on employment and GDP, although some of the fossil sectors would be negatively affected. Overall, the macauba-HEFA chain (with the highest effects on employment and GDP, and the lowest effects on imports) seemed to be the most favorable of the scenarios studied, despite the relatively high level of uncertainty associated with it.
