“…Even though the benefits of evacuation during a fire alarm are widely known (Kuligowski, 2013; Pillemer et al, 1994; Proulx & Pineau, 1996), many people still fail to evacuate during fire alarms especially in the workplace (Gwynne et al, 2016; Jelenewicz, 2008). While existing literature examines different facets of fire alarm evacuation (e.g., demographics, personality traits, knowledge and experience with fires, judgment, herd behavior, stress resistance; Gershon et al, 2012; Haghani et al, 2019; Haghani & Sarvi, 2019; Kinateder et al, 2015; Kobes et al, 2010; Nguyen et al, 2019; Proulx & Reid, 2006; Tsurushima, 2019; USFA, 2019), little research has been done on theory-based belief factors underlying employees’ decision to evacuate. This formative study, using the RAA, provides us the perspective of the worker and identifies the belief factors associated with intention to leave the office building immediately.…”

Background: Nonresidential fires and resultant injuries and deaths have been on the rise the last decade in the United States. Although evacuation is a primary prevention method, people in the workplace still fail to evacuate when they hear a fire alarm. The current formative study applied the Reasoned Action Approach (RAA) to identify belief factors associated with university employees’ intention evacuate. Methods: Data were collected from employees at a large public university ( N = 490) through an online survey. Multiple linear regression quantified the relative contribution of six RAA constructs that represent belief factors underlying employees’ intention to leave the office building immediately the next time they hear a fire alarm. Findings: Nearly 60% of the variation in employees’ intention to leave was predicted from the belief factors, adjusted R2 = 0.598, F(17, 472) = 43.80, p < .001. Controlling for demographic characteristics, five of the six RAA global constructs showed statistically significant independent associations with intention: instrumental attitude ( B = .272, SE = .026, p < .001), experiential attitude ( B = −.073, SE = .026, p = .024), injunctive norm ( B = .210, SE = .075, p < .001), descriptive norm ( B = .347, SE = .070, p < .001), and capacity ( B = .178, SE = .077, p < .001). Conclusions/Applications to Practice: These findings show the RAA can be successfully applied to provide employees’ perspective on safety decisions like evacuation. The belief factors’ relative contributions can help safety professionals prioritize interventions to facilitate leaving immediately. Here the high weights for the two normative factors suggest addressing employees’ descriptive beliefs that others like them leave and their injunctive beliefs that significant others, like supervisors and safety personnel, approve of their leaving.

“…The subjects are evacuation decision-making in wild fire, a risk-based emergency group decision method for haze disaster and flood adaption. Nguyen et al in 2019 studied individual and group evacuation decision-making separately [84]. On the other hand, Loos and Rogers in 2016 showed that utility functions can demonstrate the role of individual decision-maker values in decision outcomes [85]; however, they conclude that MCDM ensures that decision makers consider multiple benefit qualities of natural capital projects.…”

A Literature Review of the Concepts of Resilience and Sustainability in Group Decision-Making

The most critical decisions usually involve several decision makers with different roles and opportunities to commit key resources. Several group decision-making (GDM) approaches can support the identification of a joint or compromise decision in less conflicting settings, where there is a group of subjects (e.g’, partners) who pursue a common overall objective. However, considering the uncertainty in future events and complexity of modern-day systems, decision processes do not always produce beneficial results or give the participants a positive perception of their role in the process. Group decision-making should then take into consideration some aspects that might insure future resilience and sustainability, particularly the achievement of the objectives in view of future risks and the transparency and participation that are needed to limit problems in the implementation phase of the decision. The literature survey presented in this study identified a research gap regarding GDM. Differently from traditional GDM, which was first discussed in the early 1980s and whose body of knowledge is pretty defined, resilient and sustainable GDM (R&S GDM) is fairly new. The main objective of this study is then identifying the main attributes for supporting sustainable and resilient group decisions. To this aim, a preliminary focused systematic review was conducted to study the existing group decision-making methods in the literature and how the concepts of sustainability and resilience have been employed. After defining the search keywords and exclusion criteria for the individuation of the articles, the first screening process was carried out and the most relevant articles were selected. The last steps of the systematic review were the classification of the articles and the full paper examination to extract the main factors of R&S GDM. Seven attributes were listed as the key factors of R&S GDM. In light of those factors, a group decision process concerning an injection moulding line in Tajikistan was investigated. The case study highlighted that over self-confidence, information flow and transparency were the main reasons for faulty decisions, thus suggesting that information system and information fluidity play an important role in R&S GDM. Finally, the most important managerial implications of R&S GDM are reported.

“…By changing the type of groups and widths of passage, they simulated unidirectional and bidirectional evacuation processes. Nguyen et al [32] built two models that contained random and logistic regression models, and they combined the controlled behavior experiment of fire evacuation to simulate the process of individual and group evacuations.…”

Lifeboats are important equipment to ensure the safety of passengers when a serious accident occurs in the ship. Higher efficiency of lifeboat embarkation is beneficial to improving passenger survival. This study divides lifeboat embarkation into queuing and seat selection stages and studies the embarkation process of cruise passengers. According to the characteristics of two stages of the embarkation process, transfer rules of queue and activity rules of the passenger are proposed. Combined with the rules, 16 types of embarkation simulation scenarios are established. The simulation results show that the embarkation efficiency of the group passenger is lower than that of the individual passenger. When passengers select seats from outboard row to inboard row, the speed of embarkation is faster than that of random seating selection. Compared with only considering the queue length, the embarkation is more efficient if passengers also consider the seat availability of lifeboats when they transfer between queues. The analysis of the results proves that the embarkation efficiency can be improved through proper guidance on the behavior of passengers in queuing and seat selection.
