浅析项目引导、任务驱动教学法在高职商务谈判课程中的应用

为了改变商务谈判传统教学重理论轻实践的弊端和实现高职教育人才培养目标,高职院校应在商务谈判教学中引入项目引导、任务驱动教学法,按照企业商务谈判工作流程将商务谈判课程内容分为三个项目和12个任务进行教学,以此促进学生实践能力的提高。     

Research of Multiagent Coordination and Cooperation Algorithm

To solve the problem of conflict and deadlock with agents in multiagent system, an algorithm of multiagent coordination and cooperation was proposed. Taking agent in multiagent system as a player, the pursuit problem Markov model was built. The solution was introduced to get the optimal Nash equilibrium by multiagent reinforcement learning. The method of probability and statistics and Bayes formula was used to estimate the policy knowledge of other players. Relative mean deviation method was used to evaluate the confidence degree in order to increase the convergence speed. The simulation results on pursuit problem showed the feasibility and validity of the given algorithm.     

Worst-Case Nash Equilibria in Restricted Routing

We study the network routing problem with restricted and related links.There are parallel links with possibly different speeds,between a source and a sink.Also there are users,and each user has a traffic of some weight to assign to one of the links from a subset of all the links,named his/her allowable set.The users choosing the same link suffer the same delay,which is equal to the total weight assigned to that link over its speed.A state of the system is called a Nash equilibrium if no user can decrease his/her delay by unilaterally changing his/her link.To measure the performance degradation of the system due to the selfish behavior of all the users,Koutsoupias and Papadimitriou proposed the notion Price of Anarchy (denoted by PoA),which is the ratio of the maximum delay in the worst-case Nash equilibrium and in an optimal solution.The PoA for this restricted related model has been studied,and a linear lower bound was obtained.However in their bad instance,some users can only use extremely slow links.This is a little artificial and unlikely to appear in a real world.So in order to better understand this model,we introduce a parameter for the system,and prove a better Price of Anarchy in terms of the parameter.We also show an important application of our result in coordination mechanism design for task scheduling game.We propose a new coordination mechanism,Group-Makespan,for unrelated selfish task scheduling game with improved price of anarchy.     

基于遗传算法的关联议题并发谈判

基于遗传算法的并发谈判在电子商务应用中具有独特的优势,但已有的研究尚未考虑议题之间的相关性、动态权重的变化规则依赖于对手信息的获取,极大地限制了其使用价值.对此,提出议题分组的方法以解决议题的相关性问题,而议题权重的变化则采取从历史资源中发掘知识的方法进行动态调整.构建了基于遗传算法的关联性议题并发谈判模型,给出了模型的形式化描述、谈判算法设计和动态权重更新方案.通过对模型的实验和比较分析,证实了该方案能够更方便地满足用户谈判的多样性需求,解决谈判中议题关联性的问题,而且能够快速、有效地得出最优谈判结果.     

多目标进化算法在主体自动协商中的应用

研究多主体系统中主体之间的协商协议和通信协议,分析一对一协商模型,该模型采用响应型策略和慎思型策略进行协商。考虑协商双方的偏好和最大化己方的效用值,建立多目标进化算法,构造主体的预提供方案集及其支配子集,实现多主体自动协商。实验结果验证了该方法的有效性。     

基于互信息博弈的侧信道攻击风险评估模型

将互信息博弈理论引入密码芯片设计者(防御方)和攻击者的决策过程,建立一种互信息博弈的风险量化评估模型。考察攻防策略的选择对安全风险的影响,并结合互信息的量化方法,给出Nash均衡条件下攻防双方的优化策略选择方法及互信息收益。通过案例分析,验证了该策略的有效性。     

主从履带复合式机器人越障研究

针对机器人越障过程中的重心位置变化情况,提出一种主从履带复合式机器人越障研究方法。给出机器人样机模型,研究样机的重心变化规律和主履带系统链轮的负载扭矩变化规律,并进行越障和楼梯仿真分析。仿真结果表明,重心变化是影响越障和爬越楼梯成功与否的关键因素,样机重心位置发生变化时,履带系统链轮转矩将出现最大值。     

国家助学贷款新政策下的动态博弈分析

在推进国家助学贷款的过程中出现了发放和回收都不甚理想的情况，试图结合国家助学贷款新政策，从动态博弈的角度对银行与学生之间的博弈关系进行分析讨论，以期分析问题的关键，探讨新机制的运行效果。通过分析，得到这样的结论，国家助学贷款的新政策及其各项配套措施的落实可以实现该政策所期望达到的子博弈精练纳什均衡：（{贷款，追讨}，{还款，还款}），银行选择提供贷款，学生选择按约定还款。     

企业间产品创新多维博弈模型及其分析

在相关文献对典型的Cournot寡头竞争模型论述的基础上,进一步讨论在完全信息条件下两个企业关于具有一定替代性两种产品产量的静态多维Cournot模型及其多维纳什均衡,并得到两个企业分别对每种产品单独博弈时的纳什均衡策略劣于联合考虑这两种产品时进行多维博弈的纳什均衡策略的结果。     

多Agent谈判：一种基于模糊逻辑控制的方法

在分析各种Agent谈判模型不足的基础上，首先给出基于黑板模式的谈判Agent体系结构，然后设计了一个通用的谈判Agent建议的综合评价方法。此外，应用标准可加性模型原理设计了谈判Agent的策略模型，从而构建了应用范围广泛的自动化谈判Agent模型。
