“…4). An increase in ridership of MARTA by the same factor of 6 will fundamentally convert MARTA from the most carbonintensive mode to the least one in Atlanta (Azevedo, Bras, Doshi, & Guldberg, 2009). In future, it means fewer stations are required and significant reductions in transit system expansion.…”

Autonomous vehicles (AVs) have emerged as a transformative technology with the potential to both fundamentally improve lives in cities but also to exacerbate suburban sprawl, vehicle miles traveled and the associated greenhouse gas emissions. Are communities willing to adopt best practices that can lead to early adoption of more sustainable outcomes? This paper presents innovative means to analyze social preferences, demand for AVs, and the potential to resolve community concerns with integrated solutions. We discuss our comprehensive analysis of unstructured and structured data from a survey on AVs that was conducted by the Atlanta Regional Commission in 2015. We used topic modeling to synthesize the "topics" from 1,540 comments. The topics captured Atlanta residents" concerns and suggestions about implementing AVs. Further, sentiment analysis revealed people"s attitudes on the topics. Accordingly, we proposed an integration of AVs and transit-oriented development (TOD: the development of compact and mixed-use communities around high quality mass transit services within a 10-minute walking distance). The second type of data is people"s responses to multiple-choice questions about AVs and TOD, which we call structured data. Using latent-class analysis, we identified heterogeneity in preferences for AVs and TOD. More Atlanta residents are willing to live in transit-oriented communities than traditional automobile-dependent ones if AVs save time and improve productivity. This finding portends the future success of combining AVs with TOD and reaping the sustainable benefits of this transformative technology.

“…Matar et al 65 proposed a SysML systems-based model aiming to facilitate the realization of sustainable construction, by identifying the environmental impact of each production activity. In Azavedo et al, 69 a multi-scale framework was developed to model sustainability of complex systems. This study proved that the use of formal modeling by SysML makes it possible to address problem emerging from complexity management within a large, multi-layered system.…”

Recently, the company’s overall performance (OP) has become a major concern of our modern society, as a key factor that can potentially increase firm’s competitive advantage and ensure its sustainable development. However, OP is increasingly being considered as highly complex because of the complex interrelationships within industrial systems. This article presents a contribution to modeling of OP in order to apprehend its complexity and take into account the interactions between all its aspects. The proposed model is based on a combination of the value chain concept and System Modeling Language modeling. The main study established an OP indicators system to better present the firm sustainability behavior, and thus provide a comprehensive view that facilitates an in-depth understanding of its complexity. Besides, a case study from the dairy industry is presented to illustrate the model. This model can identify different activities’ interactions in the firm and understand interrelationships between OP dimensions and firm’s activities. Moreover, the proposed indicators system helps to define OP problems in the firm. Such knowledge enables managers to identify OP problems’ drivers, the related activities and set up the optimal solutions to improve the most critical activities whose performance affect the whole value chain.

“…11) Ability to Integrate with LCA tools/ data structures SysML can be exported in the Extensible Markup Language (XML), which facilitates information exchange between standards that support Metadata Interchange (XMI) [20]. SysML can also integrate between various LCA tools, which greatly expands the scope of its lifecycle coverage [49]. Work has also been done to integrate ISO 10303 and ISO 15926 with the CASCADE model, [50] which supports LCA.…”

Materials, and therefore material selections, influence the sustainable impact of a product from beginning to end-of-life. With improved access to material information, product designers can attain newfound insight into the sustainability implications of their design decisions. Insight to lifecycle tradeoffs requires access to both upstream and downstream information at design time. This access can be facilitated by information transparency between the different information representations assumed by a product throughout its lifecycle. A well-constructed Material Information Model (MIM) can provide the necessary access, and therefore the desired insight. In this paper we present an initial set of requirements that a MIM for sustainability must support to provide the desired design-time information access. Using these requirements as guidelines, we then analyze several information representations currently available for information management at various stages of the lifecycle. We compare and contrast the extent to which these representations meet the information needs of the MIM, using example implementations as guidelines. We discuss the level to which information synthesis may be achieved given the varying degrees to which the MIM requirements are met. Finally, we introduce where synthesis challenges lie and the steps required to overcome them.
