Evaluation of decision support systems for emergency management

We propose a new simulation methodology in RoboCup Rescue framework. By involving humans in simulations, we can achieve more goals than those with only autonomous agents. We focus on the evaluation of decision support system (DSS) with the methodology and show how to design and evaluate DSS. By using the method we described in this paper, the effectiveness of DSS can be measured quantitatively.

Design of RoboCup-Rescue Viewers - Towards a Real World Emergency System

In this paper the design and implementation of a prototype viewer system for the RoboCup-Rescue framework (Version 0) is described. We discuss the requirements for the visualization of disaster information and propose a workflow model for the disaster mitigation process. A prototype of disaster information system has been built, based on this model, and here we discuss the system from the viewpoint of information visualizations.

A case study of a real-time problem solving strategy in an air traffic control problem

Abstract Air traffic control (ATC) requires real-time problem solving combined with human knowledge. We present one real-time expert system in the ATC field as a case study in choosing real-time problem solving strategies. We propose a real-time search algorithm, “Time Dependent Heuristic Search” (TDHS), for obtaining at least one solution by a deadline. The usefulness of TDHS is verified in experiments with an ATC problem testbed named “AirTFM”. AirTFM is also designed to work with human controllers to help control schedule execution, letting human controllers explore plans and decide on the best modification to the original plans.

Automation of Message Handling in Cloud-based Managed Service

Abstract Abstract—As the scale of the computer systems becomes very large and complex in the latest cloud data centers, the operations of these systems should be more efficient. We analyzed the operations of an actual data center and found that approximately 30% of the time was spent on system message handling. We proposed a concept of an automated message handling system for a cloud-based managed service. This system is based on modeling an operators actions in a state transition model. We built a prototype system and evaluated its performance for three months on an actual data center. We observed that approximately 80% of the message handling was automated with the system.

Evaluation of Situated-Optimal Planning Strategy with integrate disaster simulation system

A concept known as ldquosituated-optimal planning strategyrdquo is proposed to build optimal strategies for disaster response. This concept allows one to choose optimal actions according to certain situations in order to reduce the damage. To evaluate the concept in the field of disaster response for earthquakes, we propose using a multi-agent system (MAS). In the MAS, the situated-optimal planning strategy can be mapped onto the decisions made by agents in the simulation. The results of simulations are used to evaluate the concept of situated-optimal planning strategy.

Monitoring of Carbon Sink Preservation Activity for Global Warming Countermeasure using a High-Resolution Satellite Image

We represent the monitoring method of a carbon sink preservation activity for the global warming countermeasure using a high-resolution satellite image. We first investigate the satellite image availability and make a plan of a satellite image acquisition order. Next, we propose the land-use classification using the object-based image analysis to monitor carbon sink forest. Lastly, we apply the technique to the project site in Papua New Guinea.

Building User Models for RoboCup-Rescue Visualization

Information visualization is one of the most important fields in RoboCup-Rescue research. As requirements for visualization vary by users and by their purpose of viewer use, we introduce a mechanism called user model. User models hold the requirements of typical users. They are used for the selection and customization of information, controls of viewer, and so on. We implemented the mechanism with five user models in RoboCup-Rescue 2D Viewer.
