MULTIPLE CRITERIA DECISION MAKING： DISCORDANT PREFERENCES AND PROBLEM DESCRIPTION

There are many practical decision problems where decision makers＇ preferences may be inconsistent and contradictory. In this paper, new methods for ordering and classifying multi-attribute objects by discordant collective preferences are suggested. These methods are based on the theory of multiset metric spaces. The proposed techniques are applied to ranking companies and a competitive selection of projects, which are estimated by several experts upon multiple qualitative criteria.     

液相色谱智能化——多段梯度洗脱满意分离条件之启发式自动搜索

本文为高性能液相色谱作定量分析,提供一种新颍方法,自动求得峰形分离良好的色谱图,并由此对于仪表之智能化前景作一展望。利用多段梯度洗脱法来改进分离,会引起搜索该条件之复杂化。为此,启发微机来搜索满意的分离条件,而不去搜索最优分离条件,较为合理而且方便。用本法分析人体血液中21种主要氨基酸组分,获得成功。

Best weight pattern evaluation based security constrained power dispatch algorithm

This paper presents a methodology which determines the allocation of power demand among the committed generating units while minimizes number of objectives as well as meets physical and technological system constraints. The procedure considers two decoupled problems based upon the dependency of their goals on either active power or reactive power generation. Both the problems have been solved sequentially to achieve optimal allocation of active and reactive power generation while minimizes operating cost, gaseous pollutants emission objectives and active power transmission loss with consideration of system operating constraints along with generators prohibited operating zones and transmission line flow limits. The active and reactive power line flows are obtained with the help of generalized generation shift distribution factors （GGDF） and generalized Z-bus distribution factors （GZBDF）, respectively. First problem is solved in multi-objective framework in which the best weights assigned to objectives are determined while employing weighting method and in second problem, active power loss of the system is minimized subject to system constraints. The validity of the proposed method is demonstrated on 30-bus IEEE power system.     

人生悲剧的三重验证——兼及脂批对《红楼梦》悲剧主题的揭示

被王国维视为“悲剧中之悲剧”的《红楼梦》，寄寓了作者对人生命运的深刻追问和独特思考。借助小说文本与脂砚斋批语的互证，从三个层面对其所表现的人性悲剧进行理解，阐释个体价值的悲剧、爱情理想的悲剧、人生普遍的悲剧，并进而探求其悲剧思想于人性关怀和审美意义上的启示。     

关于马克思的人的全面发展理论的一般理解

人的全面发展是马克思主义哲学的重要内容之一。要正确认识和理解马克思的人的全面发展这一理论，必须从其特定的内涵与外延上去把握，同时还要消除必要的认识误区，明白人的全面发展具有相对性。在推动人的全面发展的过程中，既要正确处理好人与自然、人与社会及人与人的关系问题，也必须清醒地认识到促进人的全面发展的现实条件，从而在实践中去推动人的全面发展。

Two Methods for Deriving Members′Weights in Group Decision Making

1　IntroductionThe Analytic Hierarchy Process(AHP) ,introduced by Saaty[7] ,is one of the popular andpowerful technique for decision making,and has also been applied to group decisionproblems(Hannan[2 ] ,Khorramshahgol and Moustakis[5] ,Islei and Lockett[3] ) .TheWeighted Arithmetic Mean Method (WAMM) and Weighted Geometric Mean Method(WGMM) are the mostcommon group preference aggregation methods in AHP.In orderto use the WAMM and WGMM,one has to find the weights to be assigned…     

一种基于POMDP用户意图建模的智能轮椅导航控制方法

通过部分可观测马尔可夫决策过程(POMDP)模型对用户意图进行建模,提出了一种基于POMDP用户意图建模的智能轮椅导航控制方法.该方法考虑了动作的不确定性和状态的部分可观测性,对用户意图、智能轮椅导航控制的动作空间进行建模,通过状态预测进而选择行为的最优规划,实现用户期望总值的最大化.首先介绍了POMDP的原理及模型,然后提出了基于POMDP用户意图的智能轮椅控制状态空间、动作空间、观察值集合、奖赏值和概率分布,进而提出了一种基于概率密度函数的用户意图求解方法.最后,对基于POMDP用户意图建模的智能轮椅导航控制进行了试验,并对试验结果进行了分析,从而验证了所提方法的实时性和有效性.
