模糊规划在结构优化设计中的应用

本文讨论了结构模糊优化设计的一般性模型,给出了最优解集和目标函数的隶属度定义,从而可以把结构模糊优化设计问题转化成约束和目标隶属度函数的普通非线性规划。算例表明,按本文的方法处理结构模糊优化设计,不仅可得出优化设计方案,而且计算量较α——水平载集解法少得多。     

一个修正的函数迭代法及其证明

本文就动态规划中函数迭代法提出了几点看法，指出了其中存在的问题，并给出了一个修正的函数迭代法及对其合理性的证明。

基于优先权提取计算信息及目标排序

本文讨论目标排序问题, 给出了一个提取可靠优先权并用于排序的决策过程, 介绍了不相容索引的计算方法。     

多目标评价的决策支持：理论、方法与实现

本文从决策支持的观点出发讨论了多目标评价问题的基本理论、方法和多目标决策支持系统的实现，指出决策者的偏好结构是解决多目标评价问题的关键因素，而多目标评价决策支持系统作为支持多目标评价问题的形成、分析和求解的软件工具，决策者的行为因素和系统的鲁棒性是其实现过程中需要重点考虑的方面。

机电设备管理信息系统中分析与决策

分析了煤炭企业的现状和未来的发展方向，据此提出了煤矿机电设备与配件管理信息系统的分析与决策系统。通过分析确定了影响系统的几个主要的因素和条件，再根据这些因素和条件确定了机电设备与配件需求数学模型，同时为了降低企业成本，又提出了定量库存控制模型和经济订货批量模型。利用这些模型可以很好地控制机电设备与配件的库存数量及资金投入，同时还不因为库存减少而影响生产。     

试论会计参与企业经营决策

企业的经营决策取决于两大信息源的支持和帮助,一是企业外部的宏观环境,包括社会、政治、经济、技术、法律等决策环境;二是企业的内部条件,包括资金、技术、物质等条件,其中资金条件起重大作用,甚至是决定作用.反映和控制资金运动的过程,便是会计的两大基本职能,企业经营决策需要会计的参与.     

DEA矩阵及应用

给出了DEA矩阵的概念、特点、性质及简单应用。     

Systems methods for environmental management

Changes in environmental research, planning, and management over the past 20 years have determined the requirements for new methodological approaches to connect environmental science and policy. This paper identifies the most prevalent directions in which the new approaches are heading based on an overview of five methods developed over the past 15–20 years. These include the environmental impact assessment methods, the adaptive environmental assessment and management approach, the environmental management and training games, decision support systems, and the policy exercise method. Conclusions of this overview are intended to provide guidelines for future methodological efforts to create better interfaces between environmental science and environmental policy.
