Title: Study on Decision Rule Optimization and Organization of Group Decision-making Abstract Group decision-making, as one of the basic forms of decision-making, plays an important role in economic and political fields due to the ever-increasing complexity of decision issue and the enhanced democracy awareness. Research of group decision-making is receiving more and more attention as the cutting edge of decision-making theory. Fruitful results are achieved in this field, while there are still some weak aspects for further research, especially in the organization and decision process ot group decision-making. Researches in those fields are instrumental in optimizing the organization and decision process of group decision-making. And we have made some exploration in this paper as follows.

随着决策问题的日趋复杂化和人们民主意识的增强，群体决策作为决策的一种基本形式，在政治和经济生活中占有越来越重要的地位，而群体决策作为决策理论研究的热点和前沿也在国内外方兴未艾，并取得了丰硕的成果，但也存在一些薄弱环节和需要深入研究的问题，特别是在群体决策的组织结构和决策过程方面，如群体决策的规则优化、决策规则的约束性质、群体决策中领导的影响、决策者之间的相关性对决策质量的影响、序贯群体决策中各种组织因素对其决策质量、决策效率、决策收益的影响等等。

针对目前我国应对重大危险源突发事故的管理和决策主要依赖于相关领导或专家掌握的知识及经验的现状，将非结构化模糊决策方法(Non-structural Fuzzy Decision Method， NSFDM)和事故后果模拟方法相结合，以区域范围内受重大危险源潜在事故影响的企业为决策对象，以减小事故影响范围，降低事故严重程度为目标，建立起重大危险源区域事故应急决策的多准则决策方法，以期帮助安监职能部门优化配置应急救援资源，提高应急响应绩效，减少国家和人民的经济和财产损失。

Decision rule chain and distance function of decision rule are proposed, by which the order of decision rules are explained. The group scale's effect on decision quality and the marginal contribution of decision-makers are analyzed. It's pointed out that the increase of the scale will enhance the decision quality with the optimal decision rule applied. Otherwise it is likely to weaken the decision quality. It's proved that for homogeneous group with simple majority rule applied the marginal contribution of decision-maker will decrease while the scale increases or the decisional competencies of other decision-makers increase; 3.We study the group decision-making with a leader in it. It's proved that the existence of the leader impairs the decision quality when the group applies the optimal decision rule.

研究了决策者的决策能力不确定情况下的群体决策，给出了最优决策规则，指出其仍然是广义加权多数规则；提出了决策规则链和决策规则距离函数的概念，利用这些概念解释了群体决策规则的序现象；分析了群体规模对决策质量的影响、决策者决策能力的边际贡献，指出当群体应用最优规则时，群体规模的增大会提高决策质量，否则群体规模的增大可能会削弱决策质量；证明了对于应用简单多数规则的同质群体，随着其规模的增大，决策者决策能力对决策质量的边际贡献会减小；随着其他决策者决策能力的提高，决策者决策能力对决策质量的边际贡献也会减小； 3。

Markov decision process and Performance Potential theory are applied to the analysis of supply characteristics.

Currently, there exist a number of web services providing similar or identical functional characteristics in our life, such as flight booking, digital music download and blog, but they exhibit divergent Quality of Services. The selection issue of QoS-aware web services involves consumer's vague perceptions of QoS, generated by individual distinct experiences and less information; thus it may be regarded as a multiple attribute decision making problem.

中文摘要目前日常生活的许多网路应用存在相似特性，例如预定机票服务、数位音乐的下载及部落格相簿等，然而这些服务功能虽然相似，但服务品质却有差异，顾客如何从众多的服务中选出适当的网路服务项目，牵涉到顾客对服务品质的属性有不同认知及偏好，且因个人的体验及资讯的不足，造成评估时的印象是模糊，因此网路服务的评选可视为一个模糊多准则决策问题(Multiple attribute decision making， MADM)。

Choosing the right checks,plaids and stripes Selecting which checks and stripes are best for you, however,is far from a fool-proof decision.the wrong choice could add extra weight and throw the silhouette off balance.The right choice,on the other hand,can offer the illusion of height and slimness.

选择正确的检查，毯子和条纹选择它检查和条纹是最适合你，但是，是从一个很简单的decision.the错误选择远非可以添加额外的重量，就扔了，另一方面，把天平的正确选择剪影，可以提供高度的幻想和slimness。

This work contributed essentially to optimal planning of refinery management. A strategy for solving the decision problem of short—term refinery planning is proposed, that is, to obtain the real time information of unit operations and environmental conditions by means of computer simulation, to dynamically configurate and modify the decision model depending on both simulation and expert reasoning, to make decision analysis and short—term production plan with the aid of expert simulation system. In this paper, a new approach cellad ESDSS was proposed by integrating DSS and expert simulation system . As a case study of ESDSS, a so called RESDSS was constructed, which is composed of seven subsystems, namely: data base subsystem, model base subsystem, method base subsystem, knowledge base subsystem, experiment base subsystem, human computer interaction subsystem, and expert simulation executing subsystem. The main results and contributions of this work are as follows:(1) A novel approach of DSS named ESDSS was proposed, which integrates DSS and ESS.

Research on the related attribute of evidence, influence and method of dealing with is carried out. Result of experiment demonstrates that the method can lead to the reliable decision effectively. Aiming at conflicting problem of decision making, fusion strategy of BPA reassign is adopted in coordinator of GDSS. Aiming at contradictory of decision-making, the process of decision-making is divided into two stages that are learning and decision-making. Each Agent is trained by proper information given by training example to eliminate contradictories among decision-making Agents and correct mistakes that ensure Agents cooperate effectively in the stage of cooperating decision.(3) In order to overcome the flaw of current GDSS that can only support static problem solving, adopting the method that combing Multi-Decision-Making-Agents Reinforcement Learning and the metempirical knowledge learning, the paper puts forward Reinforcement Learning and optimization under dynamic environment.
