Filtering for linear systems with noise correlation and its application to singular systems 下载免费PDF全文
In this paper, an optimal filter for a stochastic linear system with previous stage noise correlation is designed.Based on this result, together with the decomposition techniques of the stochastic singular linear system, the design ofan optimal filter for a stochastic singular linear system is given. 相似文献

遗传算法被广泛应用于求解车间作业调度问题(JSP),但遗传算法具有最优参数难以确定的问题。对此,该文提出了一种基于神经元动态规划(NDP)的遗传算法NDP-GA。该文将遗传算法用M arkov决策过程模型描述,建立了M arkov决策过程最优策略与遗传算法最优参数之间的联系。在此基础上,用神经元动态规划逼近M arkov决策过程的最优策略,并用学习到的策略指导遗传算法最优参数的选择。数值计算结果表明,该文提出的算法能自动收敛到最优遗传参数,并在求解JSP问题时能稳定地得到满意解。 相似文献

This paper generalizes the Pawlak rough set method to a completely distributive lattice. The concept of a rough set has many applications in data mining. The approximation operators on a completely distributive lattice are studied, the rough class on a completely distributive lattice is defined and the expressional theorems of the rough class are proven. These expressional theorems are used to prove that the collection of all rough classes is an atomic completely distributive lattice. 相似文献

供需链系统的协调机制与风险分配 总被引:5,自引:0,他引:5
为了研究供需链系统的协调机制对系统风险分配的影响,提出了一种系统风险的量化方法.使用该方法证明了供需链达到协调状态时,回购策略下供需双方风险不变;双边价格策略下,供需链上下游总有一方风险为零,另一方承担系统全部风险;而目标减免折扣策略下销售商风险始终大于供需链系统风险.结合对经典合同策略的分析,提出了一种新的策略形式,不但能够协调供需链系统,而且可将利润与风险在供需双方任意分配. 相似文献
