The autonomous decentralized system is a system whose functional order is generated only by cooperative interactions among its subsystems. In other words, the system does not have any supervisor for the entire system. Instead, each subsystem has the autonomy to control each part of the system. But, that system has not been realized yet as an artificial. Fortunately, there are many examples of the autonomous decentralized system in the biological and ecological world. In this paper, we consider a fish school as an autonomous decentralized system. The schooling mechanism of a fish behavior is studied by using modeling and simulation techniques.
A water tank experiment was carried out to obtain an observation data for fish behavior and to know a special feature of a school. The unknown parameters included in the model were estimated by using a water tank experiment data. The relationship between the information obtained by each individual and the state of school was investigated.
