θ-improved limited tolerance relation model of incomplete information system for evaluation of water conservancy project management modernization

The modernization of water conservancy project management is a complicated engineering system involving a management system, a management method, management personnel, the exertion of social, economic, and ecological effects, and so on. However, indices for evaluating the modernization of water conservancy project management are usually unobtainable in practical applications. Conducting appropriate extension of the classical rough set theory and then applying it to an incomplete information system are the key to the application of the rough set theory Based on analysis of some extended rough set models in incomplete information systems, a rough set model based on the θ-improved limited tolerance relation is put forward. At the same time, upper approximation and lower approximation are defined under this improved relation. According to the evaluation index system and management practices, the threshold for θ is defined. An example study indicates the practicability and maneuverability of the model.

According to the multi-project and program management theory, this paper analyzes the program generation principle and establishes a program based on progress goals. On the basis of the present situation of calculation of penalty for delay of the bidding section construction period with the critical path method, we studied the effects of contractor-induced delay of the bidding section construction period in detail, including the effects on the construction period of the bidding section itself, the earliest start times of the next bidding section and other subsequent bidding sections, and the construction period of the program, and then constructed a penalty model for delay of the bidding section construction period from the perspective of programs. Using the penalty model, we conducted a practical analysis of penalty for delay of the construction period of the Baoying station program in the South-to-North Water Diversion Project. The model can help determine the amount of penalty for delay of the construction period in bidding sections scientifically and reasonably,

Analysis of Winter Concrete Construction in Water Conservation Project

The construction of water conservancy projects should commence during optimal atmospheric conditions and non-flood period to ensure completion before the flood season begin in summer.In most areas of Northern China,the temperature during winter remain at lower level,in which environmental factors play the most important role in the construction of water conservancy projects.In particular,low temperature directly affects the strength of concrete and delays its solidification,this highly affects the quality and progress of concrete construction.In order to overcome this barrier,better planning,for reasonable and effective construction techniques and targeted control measures should be adopted to reduce the adverse effects of low temperature to assure a strong and safe architecture.

考虑心理倾向的大型水资源配置工程交易过程锦标激励

大型水资源配置工程特点是呈线状分布,项目法人一般组织多个工程承包方平行实施,即与多个承包方同时交易。在委托代理理论视阈下,这属于“一对多”的委托代理关系,即项目法人要同时面临源自多个代理人/承包方的道德风险。构建了考虑心理倾向的锦标激励模型,通过经典激励模型的求解,分析锦标激励差额及心理倾向对多承包方最优努力水平的影响。研究发现,承包方在质量、进度和施工安全上的最优努力水平随着锦标激励差额的增加而增加,随着承包方努力成本系数的增加而减少;承包方在这3个目标上的最优努力程度随着同情心理倾向系数的增加而减小,随着嫉妒心理偏好系数的增加而增加。因此,正确识别多承包方的心理倾向程度,并制定恰当的锦标激励机制,对提高大型水资源配置工程的建设绩效具有重要意义。
