区间数多属性决策在飞机一发失效应急程序方案优选中的应用

针对在飞机一发失效应急程序方案的选择中,很多定量因素难以精确量化的问题,将区间数多属性决策运用到飞机一发失效应急程序方案的优选中,构建了评价指标体系。此评价指标体系应用基于理想解的区间数多属性决策的相对隶属度法来选择最佳方案,该方法通过计算并查找现有方案的相对隶属度最大值来确定最佳方案。最后举例说明如何在实际中使用此方法。

Standardising and mapping open-source information for crisis regions: the case of post-conflict Iraq

Painting an accurate picture of the situation on the ground in countries in crisis is vital for the efficiency of humanitarian aid and reconstruction agencies. This study describes a method for standardising and mapping the plethora of open-source information. The test site for the study is post-conflict Iraq. Important information on aid distribution, reconstruction and security in Iraq can be derived from the reports of humanitarian aid agencies and the media, before being formatted, inserted into a database and mapped. The product is a visual, cartographic structure of otherwise random information, showing which organisations are working in the country, which thematic and geographic areas are being prioritized in the field, and which areas most frequently experience security events. This type of mapping not only highlights the overall working environment within different parts of the country, but it may also serve as a decision-making tool for donors and humanitarian aid agencies planning to deploy personnel.     

促进我国企业安全投入的对策

针对目前我国企业安全投入普遍偏少的现状,从企业目标出发,分析得出了影响企业目标的主要途径,即企业内部优化决策、企业之间生产竞争和引进高素质人才。并由主要途径分析安全投入对企业经济决策的影响,得出目前我国企业不积极进行安全投入的3点要因:由于企业决策者主观判断失误而导致的降低安全投入;企业为取得同行业之间的竞争先机,愿意冒险降低安全投入;由于企业安全生产状况信息的不透明,容易导致应聘者根据企业的规模、市场占有率、员工待遇等透明信息来判断企业安全生产状况,而导致安全投入少的企业易引进高素质人才。针对分析得出的结论,提出了一系列相应的对策措施,以改善我国的安全生产投入状况。

A NONLINEAR PROGRAMMING ALGORITHM FOR REAL-TIME HOURLY RESERVOIR OPERATIONS1

ABSTRACT: The optimization of real-time operations for a single reservoir system is studied. The objective is to maximize the sum of hourly power generation over a period of one day subject to constraints of hourly power schedules, daily flow requirement for water supply and other purposes, and the limitations of the facilities. The problem has a nonlinear concave objective function with nonlinear concave and linear constraints. Nonlinear Duality Theorems and Lagrangian Procedures are applied to solve the problem where the minimization of the Lagrangian is carried out by a modified gradient projection technique along with an optimal stepsize determination routine. The dimension of the problem in terms of the number of variables and constraints is reduced by eliminating the 24 continuity equations with a special implicit routine. A numerical example is presented using data provided by the Bureau of Reclamation, Sacramento, California.
