G.A. Siwabessy Multipurpose Reactor (RSG-GAS) is a research reactor with thermal power of 30 MW located in the Serpong Nuclear Area (KNS), South Tangerang, Banten, Indonesia. Nuclear emergency preparedness of RSG-GAS needs to be improved by developing a decision support system for emergency response. This system covers three important aspects: accident source terms estimation, radioactive materials dispersion model into the atmosphere and radiological impact visualization. In this paper, radioactive materials dispersion during design basis accident (DBA) is modeled using HotSpot, by utilizing site-specific meteorological data. Based on the modelling, maximum effective dose and thyroid equivalent dose of 1.030 mSv and 26 mSv for the first 7 days of exposure are reached at distance of 1 km from the release point. These values are below IAEA generic criteria related to risk reduction of stochastic effects. The results of radioactive dispersion modeling and radiation dose calculations are integrated with Google Earth Pro to visualize radiological impact caused by a nuclear accident. Digital maps of demographic and land use data are overlayed on Google Earth Pro for more accurate impact estimation to take optimal emergency responses.Keywords: G.A.

“…In recent years, with the frequent outbreaks of public emergencies (e.g., the "9.11" terrorist attack, hurricane Sandy in the U.S.; the SARS, Wenchuan earthquake, milk products pollution and H1N1 flu in China; the nuclear leakage in Japan; the earthquake in Haiti), relevant emergency management activities have increasingly become the focus of attention of the international community, governments and scholars [1][2][3]. It is against this background that the International Federation of Red Cross and Red Crescent Societies (IFRC) clearly defines the types of public emergencies, including hurricanes, tornadoes, typhoons, floods, droughts, earthquakes, volcanoes, epidemics, famines, food safety, manmade disasters, population migration, and technological disasters [4].…”

Decision-making for selecting response plans problem (SRPP) has been widely concerning to scholars. However, most of the existing studies on this problem are focused on public emergencies, and little attention has been paid to the decision-makers’ urgent need for solving the SRPP in response to public opinion crisis (POC) that may lead to panic buying of materials derived from public emergencies. POC has obvious characteristics of group behaviors that directly resulted from panics and psychological appeals of the public. Therefore, for solving the SRPP in POC, it is necessary to consider the deep-seated cause that result in panics and psychological appeals of the public, i.e., risk perception of the public (RPP). Firstly, the multicase study is employed to describe the SRPP of POC, and thus eight typical cases are chosen to analyze POC and its relevant response measures. Then, the RPP is described with prospect theory through considering the behavioral characteristics and critical sense of the public, the response measures of decision-makers, and the importance and ambiguity of POC. Further, considering the behavioral characteristics of decision-makers and the impact of alternative response plans on the evolution of POC scenarios, a new decision method for solving the SRPP with the intervention of the RPP is proposed by using cumulative prospect theory and a manner of comparing alternatives for each other. Finally, an example is given to illustrate the potential application and effectiveness of the proposed method.

“…For instance, poor use of decision aids has been attributed to lack of flexibility (Michalewicz et al , 2007), user interface quality (Liang, 1987) and ease of use and usefulness of the aid (Davis, 1989). In comparison, fewer studies have empirically examined human dimensions as contributory factors to suboptimal use of decision aids even though several, such as Fildes et al (2006) and Argyris and French (2017), have pointed to their relevance in understanding use-related behaviors. For instance, IT use and non-use are noted to be an effect of individual adaptation behaviors that “form a mediating link between individual reactions to new IT and the physical interaction behaviors that come to characterize their use of this IT” (Stein et al , 2015, p. 369).…”

Purpose Decision making is inherently stressful since the decision maker must choose between potentially conflicting alternatives with unique hazards and uncertain outcomes. Whereas decision aids such as decision support systems (DSS) can be beneficial in stressful scenarios, decision makers sometimes misuse them during decision making, leading to suboptimal outcomes. The purpose of this paper is to investigate the relationship between stress, decision making and decision aid use. Design/methodology/approach The authors conduct an extensive multi-disciplinary review of decision making and DSS use through the lens of stress and examine how stress, as perceived by decision makers, impacts their use or misuse of DSS even when such aids can improve decision quality. Research questions examine underlying sources of stress in managerial decision making that influence decision quality, relationships between a decision maker’s perception of stress, DSS use/misuse, and decision quality, and implications for research and practice on DSS design and capabilities. Findings The study presents a conceptual model that provides an integrative behavioral view of the impact of a decision maker’s perceived stress on their use of a DSS and the quality of their decisions. The authors identify critical knowledge gaps and propose a research agenda to improve decision quality and use of DSS by considering a decision maker’s perceived stress. Originality/value This study provides a previously unexplored view of DSS use and misuse as shaped by the decision and job stress experienced by decision makers. Through the application of four theories, the review and its findings highlight key design principles that can mitigate the negative effects of stressors on DSS use.
