油气资源勘探与开发的不确定性分析及最优策略

基于油气资源勘探与开发的特点,建立了油气藏勘探发现率及储量模型,并在油气价格服从几何布朗运动条件下,以油气开采收益最大化为目标,建立了油气资源勘探与开发的随机最优控制模型,然后运用动态规划方法推导了在状态方程有几何布朗运动、带随机泊松跳过程条件下,值函数所满足的HJB方程,并对最优策略的求解进行了一些讨论.

ERP实施中的成本-进度管理

我国有很多企业实施了ERP项目，但是成功率却很低。从管理和技术两个不同的角度分析了失败的原因，提出了成本一进度管理的观点，并相应地提出了在实施过程中制定工作分解结构、成本进度表和统一软件过程的方案。     

A ROBUST DECOMPOSITION OF LINEAR PROGRAMMING USING A GOAL-PARTITIONING METHOD

The Dantzig/Wolfe linear programming decomposition algorithm has had important economicinterpretations as well as a widespread impact on solving large scale linear programming problem.Inthis paper we consider a similar underlying structure,where however there is only one couplinginequality or equation.With this simplification,we demonstrate how to achieve an equitable partitionof the overall coupling resource to individual subproblem constraints through a simple iterationprocedure which appears to be very efficient.     

系统的分散与集中的决策：（Ⅱ）分散控制效果分析

分散集中系统是一种重要的工业过程控制系统．合适的分散度有利于提高系统的性能指标，尤其是动态响应速度和误差时间的积分值都有明显地改善．文中提出若干系统分散的选择原则，并用仿真和理论分析加以证明．     

Method for Risky Multiobjective Group Decision-Making and Its Application

The multiobjective group decision-making problem under risk is common in reality. This paper focuses on the study about risky multiobjective group decision-making problem where the index value is not certain. We give indexes classifying method and index normalizing formula of this type problem. By building objective function that minimizes general weighted distance from every alternative to the relatively best and worst alternative, the optimal membership degree of every decision-maker to every alternative can be obtained, and by building another objective function that minimizes general weighted distance from the optimal membership degree of every decision-maker to every alternative to the group optimal alternative and the group inferior alternative, the optimal membership degree of every decision-maker to every alternative can be obtained, which are both based on probability theory and fuzzy theory. Aftermost a model is established which collects group preferences. This method provides a new idea and
