Abstract: A method for planning attacking targets to optimize a use of own available resources in a target area based upon information on own resources available for attacking and information on protected and non-protected targets located in the target area. Different attack tactics are collected in a first library. Different defense strategies are collected in a second library. A reward value is allotted to each target and threat in the target area. Each target and threat in the target area has a defense capability and a vulnerability. The different attack tactics for a chosen defense strategy are evaluated to find an optimal attack tactic having a highest possible accumulated value of target reward value combined with a defeat probability value. The found optimal attack tactic is utilized to create an attack plan involving information on resources needed, targets to attack and attacking directions and time delays.
