Geospatial analysis of cooperative works on asymmetric information environment

Abstract

In the so-called Information-Explosion Era, astronomical amount of information is ubiquitously produced and digitally stored. It is getting more and more convenient for cooperative works in the sense of information sharing. Information aggregation systems are widely available and search engines are the most useful tools for finding resources on the internet. However, the use of information is not sufficient for cooperative works such as decision making. This is partly because, as the systems get larger, the stakeholders of the systems increase and they are on Asymmetric Information Environment (AIE). We do not share everything on the network. In this paper, we present the importance of AIE-oriented systems design for cooperative works using simulations and geospatial analysis on Multi-Agent Disaster Evacuation Model. As a result, using small data like positioning information and status information of agents, we can visualize the situations and take effective actions for cooperative works on AIE. Communication techniques on AIE such as signaling, positioning information monitoring and positioning information screening are effective for geospatial analysis of cooperative works on AIE. In conclusion, we can increase values from information flows by increasing effective actions for cooperative works using AIE-oriented systems design. Real field experiments are to be followed in our plan. © 2010 Springer-Verlag Berlin Heidelberg.
