MA Yan-ha · Fire Control and Command Control · 2014
In order to overcome the difficulty caused by using Bayesian network in situation awareness in subjective situation and facilitate the excessive work to specify the CPTs the amount of which grow exponent with the number of nodes in the Bayesian network,a new method was proposed based on the influence net for situation awareness. The method proposes here uses two kinds of influence relations included promote and inhibiting influence,providing an intuitionistic and intelligible model for the situation awareness. By using CAST logic,the CPTs easily is gotten,the knowledge of domain experts is expressed,and a new method to is provided get CPTs when its difficult to get.
