Communication Support System for Operators in Emergency of Large Scale Plant

Abstract It is very important to support communications among operators in the emergency of large scale plants. This paper deals with a communication support system for emergent situations in a hierarchical management structure for large scale plants. Our system is based on the communication model which considers human related factors such as “competence”, “duty”, “responsibility” and “knowledge”. A prototype of a group communication support system is developed based on the model, and the system is evaluated for a plant example
