本文对多目标动态规划分层解法进行了改进和完善,采用分阶段搜索筛选的办法求解各目标在相应的工程宽容范围内的允许策略集合,使这一方法更具适应性和实用性。文中概述了这种动态多目标决策方法在载人航天环境控制和生命保障系统方案评价和优化中的应用。最后给出了这种方法在求解代谢氧回收再生过程技术方案评价优化中的具体应用实例。
This paper improves and perfects the hierarchical solution of multi-objective dynamic programming. The method of phased search and filtering is applied to solve the set of allowable policies of each objective in the corresponding project tolerance, making this method more adaptable and practical. The paper summarizes the application of this dynamic multi-objective decision-making method in the evaluation and optimization of the program of manned space environment control and life support system. Finally, the practical application of this method in evaluating and optimizing the technical scheme of the metabolic oxygen recovery and regeneration process is given.
