Embodiment 1

[0072] In order to verify the effectiveness of the method of the present invention, a heterogeneous aircraft multi-task cooperative allocation method (Task Precedence Gene Algorithm, TP-GA) and random search method (Random Search Method, RSM) disclosed in the embodiment are used respectively. Solve the multi-task cooperative assignment problem of heterogeneous aircraft in the modern weapon mission planning system. The simulation hardware is Intel Core i5-2310CPU 3.10GHz 4G memory, and the simulation environment is MATLAB. In each iteration of TP-GA, 66% of offspring are generated by crossover, 32% of offspring are generated by overall mutation, and the remaining 2% are used to retain the best individual in the parent generation. In addition, RSM randomly generates nfe chromosomes that meet the constraints according to the number of model calls nfe, and selects the optimal individual as the result output.

[0073] Two different scenarios are used to illustrate the feasibility ...

Abstract

The invention discloses a heterogeneous aircraft multi-task cooperation allocation method considering a timing sequence constraint, relates to a heterogeneous aircraft multi-task cooperation allocation method, and belongs to the field of aircraft task planning. An aircraft type is obtained according to tasks, and a flight performance parameter is extracted according to the aircraft type; a heterogeneous aircraft multi-task cooperation allocation model considering the timing sequence constraint is established; and the heterogeneous aircraft multi-task cooperation allocation model considering the timing sequence constraint is solved by utilizing a genetic algorithm considering the time sequence constraint, and a heterogeneous aircraft multi-task cooperation allocation scheme meeting the task time sequence constraint and maximum efficacy can be obtained. The invention provides a task allocation method capable of planning the allocation scheme meeting the task time sequence constraint and the maximum efficacy for a heterogeneous aircraft, task execution time can be effectively shortened, and task efficacy is improved. The heterogeneous aircraft multi-task cooperation allocation method is suitable for an observation-hitting-evaluation fight, wide-area search and a damage or air defense suppression task, and has wide engineering application value.

Description

technical field [0001] The invention relates to a multi-task cooperative allocation method for heterogeneous aircraft, in particular to a multi-task cooperative allocation method for heterogeneous aircraft considering timing constraints, and belongs to the field of aircraft task planning. Background technique [0002] Facing the increasingly complex modern battlefield environment, battlefield tasks are gradually developing in the direction of diversity and complexity. A single aircraft is limited by its own software and hardware conditions, and cannot carry out large-scale continuous reconnaissance and strike missions, and the failure or shooting down of a single aircraft will directly lead to mission failure. In order to cope with the limitations of a single aircraft, through the cooperation of heterogeneous aircraft, the advantages of multi-source information fusion and resource complementarity are formed, and the reliability, fault tolerance and combat effectiveness of th...
