To help disaster response organizations improve the management of regional emergency assets and operations, we propose to interface an agent-based, discrete event simulator with a geographic information system and a rule base (describing standard policies and protocols for various disaster responses). The system architecture will enable modules to(More)
Simulation has many advantages in modeling complex systems to facilitate decision making. In this research, an integrated computer system will be developed which incorporates an agent-based discrete event simulator, a geographic information system, a rule base, and interactive databases in addition to interfaces and other supporting components. The modules(More)
Disasters are complex events that involve multiple actors trying to gain control over and manage rapidly changing situations. We have developed an "all hazards" disaster modeling system called the Dynamic Discrete Disaster Simulation System (D4S2) that seamlessly integrates ArcGIS 9.2, Rockwell Automation's Arena discrete event simulation, a custom built(More)
We have merged agent-based modeling, discrete event simulation, and geographical information systems (GIS) into one seamlessly integrated platform to simulate major disaster events in real time. One advantage of this hybrid architecture is the ability to assess the impact of agent rules on outcomes in disaster scenarios. A heuristic top-level framework has(More)

Using Chinese National Knowledge Infrastructure as the data resource, this paper searched some papers about open access (OA). Some Visual Basic for Applications programs were developed to generate the co-word matrix, compute the E-index value of keywords as well as the density and centrality of thematic clusters. Callon’s clustering method was also used to(More)
BACKGROUND Acute gastrointestinal injury (AGI) is a common problem in the intensive care unit (ICU). This study is a review of the gastrointestinal function of patients in critical care, with the aim to assess the feasibility and effectiveness of grading criteria developed by the European Society of Intensive Care Medicine (ESICM) Working Group on Abdominal(More)
