Top1. Introduction
With the development of science and technology, the advantage of artificial intelligence in man-machine games has gradually emerged, and it has made breakthroughs in games such as the two-person zero-sum, in-depth decision-making, multi-agent control, and incomplete information game scenarios. In March 2016, AlphaGo beat top player Lee Se-dol 4:1 in real-time go games(Joshi & Shashank, 2016), and later in 2018 and 2019, artificial intelligence based machines beat the world's top human players in real-time strategy games Dota2 and Starcraft II(Raiman, Zhang, & Wolski, 2019).
In the system of system operations, the confrontation is not only limited to the performance of weapons but also includes the intelligence competition. Relying solely on pilots' independent evaluation and decision-making has been unable to meet the complex and changeable combat environment. The future air combat time will be reduced and the confrontation will be more intense. Pilots should predict the situation and maneuver decision-making. Greater demands were being placed on the pilots by a large amount of battlefield information, However, the current control system in use mainly displays the status information of the target and the aircraft, which increases the control burden of the pilot in target tracking, attack occupation, and maneuver evasion. This will inevitably lead to an increase in pilots’ decision-making error rate and the decrease of pilots’ survival probability, which will affect air combat effectiveness. Therefore, it will be of great significance for future warfare decision-making problem. For example, in severe climate areas such as high and cold areas, military personnel have limited acting ability and develop unmanned counter equipment for unmanned intelligent control, assisted decision-making, simulated counter training, etc. This transformation reduces the burden of pilots, liberates them from tedious micro-operations, and has sufficient time and energy to command Macro mission combat.
Air combat decision-making refers to the choice of attack and defense strategies according to the battlefield situation. Air combat decision-making is a NP hard problem(Leitmann & Skowronski, 1977). In this work, we focus on this problem into a sequential multi-step problem, and a genetic fuzzy reasoning based and intelligent assistant decision-making method is designed. By using fuzzy reasoning method to extract the battlefield feature vector including the opponent commander's emotion, behavior and the decision state of the evolution process of the battle method, then using the rule tree method to simulate the decision process in series, and based on the genetic algorithm to search and evaluate the fuzzy rule tree until the best action decision sequence is obtained.
