Target Threat Evaluation for Air Attack Based on Rough Set and Intervals
Li Zhou · Fire Control and Command Control · 2011
Considering the existing methods of target threat evaluation for air attack was not fully ideal,a new evaluation method based on rough set and intervals was proposed.Criterion systems of target threat evaluation for air attack was founded,the calculation steps for solving index weight was given when index value was intervals and index weight was unknown,which conquered the subjectivity of former methods.Then the mathematical model of evaluating target threat by rough set and intervals was established.Dispersed ranges of threat evaluation indexes were presented,and the criterion systems of target threat evaluation was reduced by rough set theory.Finally,a numerical example of target threat evaluation for air attack is given to show the rationality and effectiveness of the method.
