基于服务质量和价格的服务竞争行为

服务供应商承诺的服务质量和实际的服务质量之间的差异会显著地影响其需求. 从服务质量的可靠性维度和价格两个方面来分析服务供应商之间的竞争行为. 服务需求由服务质量和价格共同决定.根据服务供应商的不同竞争行为,分别建立以下三种竞争模型：1.服务质量一定的情况下基于价格的竞争模型. 服务供应商之间存在唯一的纳什均衡解;2.价格一定的情况下基于服务质量的竞争模型. 服务供应商的最优决策不受其他任一服务供应商的影响;3. 基于服务质量和价格同时 竞争的模型.以服务供应商收益最大化为目标,得到每种竞争模型下服务供应商的最优 价格、服务质量和相应的需求.服务供应商不同的竞争策略会产生不同的均衡行为.     

Complexity and intransitivity in technological development

This paper investigates the existence of a fundamental link between two disciplines that emerged during last few decades： complexity science and advanced engineering. During this time many industries, especially those related to the high-tech end of technological development, have faced the problem of increasing complexity of design, production and operation. Industrial projects have grown to become multidisciplinary, tightly interconnected, costly and difficult to control and predict. Two trends can be identified in this respect： one is the consistent effort of systems engineering in reducing the uncertainties of complex industrial operations and the other is the effort undertaken in complexity studies to account for uncertainties present in the real world.
In this work, we provide a brief overview of recent developments in advanced engineering and give a consistent interpretation of technological evolution from the perspective of complexity science in general and complex competitive systems （CCS） in particular. CCS is a general framework that was recently developed for analysis of complex systems involving competition. Transitivity of the decision-making process and the cyclic nature of technological progress are considered. Correctness of intransitive decisions is inherently relativistic： the same decisions can be seen as correct or incorrect when considered from different perspectives. When treated simplistically, intransitivity may seem to be illogical but, nevertheless, it is common in nature and needs to be studied. CCS provides a formalised scientific framework for analysis of intransitivity and establishes the existence of an important connection linking complexity and uncertainty with intransitivity. Implications of intransitivity for engineering decision-making and strategic planning are considered in the context of CCS. A working example of intransitivity in competition between major car mantifacturers is presented.     

SIMPLE COMPUTING OF THE CUSTOMER LIFETIME VALUE:A FIXED LOCAL-OPTIMAL POLICY APPROACH

In this paper,we present a new method for finding a fixed local-optimal policy for computing the customer lifetime value.The method is developed for a class of ergodic controllable finite Markov chains.We propose an approach based on a non-converging state-value function that fluctuates（increases and decreases） between states of the dynamic process.We prove that it is possible to represent that function in a recursive format using a one-step-ahead fixed-optimal policy.Then,we provide an analytical formula for the numerical realization of the fixed local-optimal strategy.We also present a second approach based on linear programming,to solve the same problem,that implement the c-variable method for making the problem computationally tractable.At the end,we show that these two approaches are related：after a finite number of iterations our proposed approach converges to same result as the linear programming method.We also present a non-traditional approach for ergodicity verification.The validity of the proposed methods is successfully demonstrated theoretically and,by simulated credit-card marketing experiments computing the customer lifetime value for both an optimization and a game theory approach.

工件具有区间限制的批在线调度

研究同构并行机上的批在线调度问题,目标函数是使最大完成时间(最后一个工件的完成时间makespan)最小.工件以批方式到达且每个批中有m个工件,每个工件的加工时间随其批的到达而给定且限定在某个时间区间上.当一批工件到达时,在对其后批的信息不了解的情况下,要立即对该批中的工件进行调度,调度过程中不允许中断.针对这一问题,给出了一个批在线启发式列表调度算法,在同一批中的工件按LPT规则调度,当一批中的全部工件被调度完后,调度下一批中的工件.对算法的最坏情况进行了分析并给出了算法的竞争率.     

基于系统的角度：“区域品牌形象”应作为评价区域竞争力的一个新要素

论文分析了区域品牌形象具有的特征。指出了区域品牌形象的三个作用：有利于树立区域的整体形象;有利于各类资源要素的有效配置,降低区域运行成本;使区域品牌形象与单个组织的品牌形象产生正面的叠加效应。论文从我国区域品牌形象的覆盖面、区域品牌形象竞争的性质、区域品牌形象竞争的结果三个方面分析了我国当前区域品牌形象建设的现状,指出了存在的主要问题是相关的法律法规建设滞后;各地在塑造区域品牌形象的过程中具有强烈的行政色彩;重宣传、轻内涵,重开发、轻维护,可持续性发展较差。论文最后就塑造我国区域品牌形象提出了相关策略：建立健全相关的法规;将区域品牌形象纳入评价区域竞争力的准则之中;明确区域品牌形象的主体;塑造各具风格特色的区域品牌形象。
