本文针对内河航运中水利枢纽通航拥堵问题,在拥堵收费下引入心理期望成本,以探寻面向双过坝模式(通航建筑物过坝和翻坝转运)的优化策略。首先,应用非抢占式M/M/1排队系统,构建了以综合过坝成本为参考点的决策模型,提出了三种情形(无心理期望成本、通航建筑物过坝的心理期望成本、双过坝模式的心理期望成本)下的船舶过坝优化策略,并对比分析了通航建筑物过坝比率、船舶平均等待时间和过坝系统总成本;然后,引入对翻坝转运的补贴策略,通过调整心理期望成本水平,来影响船舶过坝策略选择;最后,以三峡工程为例,验证了上述模型的有效性。结果表明:在拥堵收费下,考虑船主心理期望成本,可以促进过坝方式的转移,降低船舶过坝平均等待时间,且双过坝模式中均考虑该因素更有利于提升通航效率;同时,实施翻坝转运补贴策略,能充分发挥心理期望成本的调节作用,从而有效缓解水利枢纽通航拥堵问题。

以6批8 171个中国传统村落为研究对象,基于地理网格分析传统村落空间分布特征及影响因素。研究结论如下:(1)中国传统村落的空间分布形态为集聚型,传统村落密集分布的省际边界现象显著,表现为冀鲁豫交界、皖浙赣交界、黔桂湘交界3大集聚区;(2)传统村落空间分布的空间自相关性明显,存在“高-高”“低-高”“低-低”空间聚集,长江以南的山地丘陵地区是中国传统村落分布的密集区,东北和西北边陲地区是传统村落分布的稀疏区;(3)交通、经济因素对传统村落空间分布影响不显著,地形、气温、生态、人口因素对传统村落空间分布有着正向影响,降水因素对传统村落空间分布有着较小的负向影响,人口、城镇、生态因素对传统村落空间分布的影响具有较强的空间异质性。

It is the trend of operational evaluation that the computers automatically assess instead of man. This paper introduces the mathematical model of the synthetic fuzzy evaluation for operational evaluation of marine power station. The various factors which affect manual paralleling of power station are analyzed and membership functions are established. This evaluation method is applied to a computer based operational evaluation for 2nd/3rd engineers for manual accurate synchronizing of power station. The veracity and effectiveness of synthetic fuzzy evaluation methods are demonstrated here. This research project has passed the acceptance appraisal by Scientific and Technical Department of shandong province and is recognized meeting the domestic leading standard.

基于因果聚类和模式识别的模糊预测方法,是将企业待预测时段的运行状况与历史上的运行模式相比较,根据"最大隶属原则"将待预测时段的运行状况归入某一运行模式,利用此模式的模糊数对预测量进行预测。

Magnetic-liquid suspension guide-way system( MLSGS) is coupled supported by permanent magnetic suspension and hydrostatic bearing. The structure and bearing mechanism of MLSGS of heavy computer numerical control( CNC) machine tools are introduced and the mathematical expression of bearing force of bearing unit is derived and it can be broken apart into six parts which sustains directly the coordinate components of broad external load,where the air gap of permanent magnet and hydrostatic oil film can be simplified as elastic supports,the compatibility equations of deformations for oil films and air gap are presented,and then the bearing capacity calculation of the bearing unit is transformed into a determinate problem. Considering the guide-way as a rigid body,the mathematics expression between the bearing unit's bearing force and the oil film variation is linearized,and the oil pocket's bearing capacity which bears different components of the external load is calculated separately. The six components of the bearing unit are added up,and the final general mathematics expression is derived. The proposed research offers a general simple method for calculating the bearing capacity of MLSGS with complicate constraint,which can be mastered simply by engineering designer and can improve design efficiency and accuracy.

在服务行业中,由于服务的无形性,面对不确定的服务质量时,不同的顾客根据自己的偏好心理采取不同的决策方案。为了探究延时敏感顾客的不确定型决策对企业服务质量信息披露与否策略选择的影响,本文考虑M/G/1队列,通过建立企业服务质量信息披露与否两种策略下的顾客效用模型,利用排队博弈理论,分析引起顾客均衡进队策略和企业收益最大化的服务定价变化的相关影响因素并探究其影响。研究表明:披露服务质量信息并不总是使得企业获得较大的收益,此外,当企业隐藏服务质量信息时,如果乐观型顾客比例大于一定值时,最优价格反而出现下降的趋势;企业服务质量信息披露与否的选择是以服务质量和顾客类型有关,只要当乐观型顾客比例超过一定值时,隐藏服务质量信息就可以获得较高收益。
