摘要： 提出一种两阶段多目标决策方法，应用于飞机环控/发动机系统的多目标决策分析。将起飞、加速爬升和高空超音速巡航阶段的总熵产最小视为不同目标函数以建立多目标优化模型，采用多目标优化算法得到非劣最优解集。在此基础上进行方案初选，利用改进综合权重的Vague集决策方法对备选方案进行模糊评价和优选，并找到最终解。计算结果验证了该方法的合理性。

Abstract: A two-phase multi-objective decision method is proposed to the multi-objective decision of aircraft environmental control system and engine. The total entropy generation minimum at flight phases of take-off, climb and supersonic penetration are regarded as different objective, the multi-objective optimization model is established. The Pareto optimal set is obtained by multi-objective optimization algorithm. Based on the Pareto optimal set the scheme primary selection is done, and it evaluates the selected scheme through Vague set decision-making method with improved integrated weight, the final optimal scheme is obtained. Results validates the rationality of the method.
