Decision-making approach to UCAV based on gray interval relative theory

To solve the problems of tactical decision-making for unmanned combat air vehicle(UCAV) under the condition of incomplete information, an independent tactical decision-making approach to UCAV based on gray interval relative theory was proposed. The decision-making elements were selected and the UCAV decision-making reasoning rule base was established in accordance with the combat mission's requirements. Incomplete information was modeled, a tactical decision-making model for UCAV was established according to the theory of gray interval relative. Conflict resolution algorithm, an effective solution to reasoning failures caused by the incomplete information, was designed. Some experiments were presented to simulate the decision-making process, the feasibility in resolving the UCAV tactical decision-making problems and the validity in resolving the rule match conflicts was verified. The results show that the approach is able to deal with the uncertainties of the decision-making factors, and gives reasonable results.
