房地产项目的投资决策分析流程再造研究

章介绍了业务流程再造的基本内涵，并就房地产项目的投资决策分析流程进行重点研究，对房地产项目的投资决策分析流程进行了重新构建。     

基建项目工程造价的重点控制

工程造价的控制重点应在建设项目的前期阶段 ;投资决策阶段应控制项目的可行性 ,设计阶段要从设计方和业主方优化设计概算 ,招投标阶段要强化招投标过程的规范性     

Short-Term Water Consumption Patterns in Ciudad Juárez, Mexico

Water utility planning efforts are becoming increasingly difficult throughout the world. Located in a semi-arid region, Ciudad Juárez, Mexico is a fast growing municipality that faces both physical infrastructure and water supply constraints. This paper examines monthly water consumption in Ciudad Juárez utilizing a linear transfer function procedure (LTF). Analysis is carried out for per customer usage and for the total number of municipal water system accounts. Models estimated for both series are subjected to a series of simulation benchmark tests. Findings suggest that water consumption in Ciudad Juárez reacts quickly to changes in economic and weather conditions. Out-of-sample simulation results are mixed. Per customer usage forecasts do not fare as well those for total customers relative to random walk benchmarks.Financial support for this research was provided by Southwest Center for Environmental Research Policy Grant W-04-03. Additional financial support was provided by El Paso Electric Company, Wells Fargo Bank of El Paso, and National Science Foundation Grant SES-0332001. Helpful comments and suggestions were provided by Cely Ronquillo, Brian Kelley, and Cesar Olivas. Econometric research assistance was provided by Marycruz De Leon and Irma Torres.

项目评价中的生态资源经济价值研究

在项目评价中,往往需要评价项目对生态资源造成的经济影响。而生态资源价值一般通过非经济指标表现出来,这就造成项目评价中衡量单位不一致的矛盾。目前必须在项目评价理论分析的基础上,将生态资源价值构成及分类理论与市场价值法方法有效地结合起来,进行定量分析,并将其转化为经济指标,以利于市场经济条件下的项目评价。     

The Research of the Construction Time on City Infrastructure Projects

The project construction time is not sufficiently considered in the decision-making procedure of the extant city infrastructure project all over the world. From the principle to increase benefit from the investment, the paper discusses the influence of construction time on benefit from investment, the condition of the optimal construction time, the method to confirm the optimal construction time, etc., under the increases of market demand, the paper establishes mathematics model between the construction time and the project benefit, and the model involves the project age, the construction time, the capital cost, the market demand, the discount rate and so on. Finally, the paper quantitatively analyzes the influence characteristics and degrees of construction time to the project profits, and the method to determine the optimal construction time of a project under different market demand .To emphasize that, the paper researches on Chinese cases, but, the conclusion put forward has the widespread significance to the time choice on city infrastructure project of other countries.     

审计项目后评价指标体系构建研究

目前，我国审计机关对审计项目尚缺少一套科学、量化的后评价指标体系。本文从实施审计项目后评价的意义、系统要素、评价的主要内容及后评价体系构建四个方面加以阐述。在构建评价指标体系时采用定量和定性相结合的评价方法，同时兼顾可行性和可操作性。     

臭氧在饮用水处理过程中的应用

地下水源污染日益严重。将臭氧-活性炭-纳滤膜应用于浅层地下水的净化中，该工艺能有效地去除地下水中的有机污染物，臭氧对地下水中CODMn,UV254、TOC等有机物综合指标去除率平均为13％、15％、17％，臭氧一活性炭联用后时CODMn和UV254的去除效率分别为64％、69．8％、64％，纳滤膜对CODMn和UV254、TOC的去除效率分别为58％、65％、65％。

工程项目T、Q、C决策优化方法研究

工期(T)、质量(Q)和成本(C)是项目建设中,决策者最为关注的三个目标,它们在不同的工程项目中表现出不同的决策要求。本文研究了T、Q、C三者发生不同变化时的决策情形,并给出了相应的决策优化思路和方法,为项目决策人提供了一定的决策参考依据。
