“…According to Kok (2009), Mazlack (2009, Carlucci et al (2013) and Ferreira and Jalali (2015), there is a state vector n × 1, which includes the value of n concepts; and a n × n weight matrix W (also known as adjacent matrix), that gets together all the weights W ij and the relationships between the n criteria. Accordingly, the value of each concept is influenced by the values of its interconnected concepts and by its own previous value.…”

Abstract. Risk analysis of residential real estate investments requires careful analysis of certain variables (or determinants). Because real estate is a key sector for economic and social development, this risk analysis is seen as critical in supporting decision processes relating to buying or selling residential properties, partly due to the pressures caused by the current economic environment. This study aims to develop a conceptual reference model for risk assessment of residential real estate using fuzzy cognitive mapping. This fuzzy model allows cause-and-effect relationships between determinants to be identified and better understood, which in turn allows for better informed investment decisions. The results show that the use of cognitive maps reduces the number of omitted criteria and favors learning with regard to how the criteria relate to each other, holding great potential and versatility in structuring complex decision problems. Practical implications, strengths and weaknesses of our proposal are discussed.

“…FCM scenario simulation analysis focuses on the effect that each concept has on the other concepts in the network over a number of iterations or time steps (k) (normally 20−30 iterations) [45].

Low-income residents are among the most vulnerable groups to climate change in urban areas, particularly regarding heat stress. However, their perceptions about heat and the impacts they face go often undocumented, and are seldom considered in decision-making processes delivering adaptation. This paper presents a robust tool to allow the integration of perception, concerns and impacts of different income groups in urban adaptation planning and governance, using the City of New York as a case study. Employing online interviews-a solid method to reach poorer households-and Fuzzy Cognitive Mapping, we compare impacts and adaptation perception to heat and simulate adaptation scenarios. Results reveal that lower income groups are more concerned about impacts of heat waves than middle-and high-income populations. All income groups see citizens more in charge of adaptation, although more people from the lower income groups regard it necessary to do much more to protect themselves, proportionately more people from the higher income groups think they are doing the right amount. The scenario analysis shows that, compared to investments in the water/electricity and health system, improvements in the transit system would yield the largest decrease in negative impacts during heat, benefitting all income groups jointly.

“…Other tools for capturing stakeholder perspectives on systems, such as fuzzy cognitive maps (Kok, 2009;van Vliet et al, 2010) and other participatory modeling tools (Voinov & Bousquet, 2010), do allow for a systems description that includes semiquantification of relationships and feedbacks among system elements. These models, in turn, have no specific focus on system levels and scales.…”
