卡通流水生成系统

介绍了一个卡通流水生成系统。在系统中用户先交互画出少量的控制点，再通过选择水波类型以及输入少量参数，系统便可以自动生成与目前电视动画中的卡通流水质量相当动画序列。系统主要包括4个部分：流水路径控制模块，水波类型控制模块，水波以及浪花生成模块。流水路径控制模块根据用户输入的控制点和透视参数生成流水路径控制曲线族以确定流水的路径和水面覆盖范围，水波类型控制模块则定义了卡通流水中常见的水波类型，水波以及浪花生成模块则根据系统内部定义的水波类型生成不同的水波与浪花。该系统可以使普通的用户把复杂的卡通流水手工绘制劳动转化成输入少量的点和参数，从而显著提高卡通动画的生产效率并节约大量纸张。

A calculus for services innovation

Innovation in the services area - especially in the electronic services （e-services） domain - can be systematically developed by first considering the strategic drivers and foci, then the tactical principles and enablers, and finally the operational decision attributes, all of which constitute a process or calculus of services innovation. More specifically, there are four customer drivers （i.e., collaboration, customization, integration and adaptation）, three business foci （i.e., creation-focused, solution-focused and competition-focused）, six business principles （i.e., reconstruct market boundaries, focus on the big picture not numbers, reach beyond existing demand, get strategic sequence right, overcome organizational hurdles and build execution into strategy）, eight technical enablers （i.e., software algorithms, automation, telecommunication, collaboration, standardization, customization, organization, and globalization）, and six attributes of decision informatics （i.e., decision-driven, information-based, real-time, continuously-adaptive, customer-centric and computationally-intensive）. It should be noted that the four customer drivers are all directed at empowering the individual - that is, at recognizing that the individual can, respectively, contribute in a collaborative situation, receive customized or personalized attention, access an integrated system or process, and obtain adaptive real-time or just-in-time input. The developed process or calculus serves to identify the potential white spaces or blue oceans for innovation. In addition to expanding on current innovations in services and related experiences, white spaces are identified for possible future innovations; they include those that can mitigate the unforeseen consequences or abuses of earlier innovations, safeguard our rights to privacy, protect us from the always-on, interconnected world, provide us with an authoritative search engine, and generate a GDP metric that can adequately measure the growing knowledge economy,

并行程序与状态序列--交叉语义约定的研究

许多程序模型是以数学或逻辑为基础设计并分析的,但程序模型的实现首先是个物理系统,它依物理规律,而非数学或逻辑规则活动.但人们习惯于用状态序列对并列程序模型的语义作数学处理.一旦偏序的状态空间用交叉的方法全序化,并用于论证程序性质,误导就在所难免.所谓误导,指的是与实际运行的偏差,借助于Petri网,可以将它们暴露出来.其实偏差的出现与Petri网的基本现象冲突(conflicct)、冲撞(contact)、并发(concurrency)和混惑(confusion)相关.本文用Petri网分析误导的情况.

Fundamentals of the analytic network process — multiple networks with benefits,costs, opportunities and risks

The general theory of the ANP enables one to deal with the benefits, opportunities, costs, and risks (the BOCR merits) of a decision, by introducing the notion of negative priorities for C and R along with the rating (not comparison) of the top priority alternative synthesized for each of the four merits in terms of strategic criteria to enable one to combine the four B, O, C, and R values of each alternative into a single outcome. Strategic criteria are very basic criteria individuals and groups use to assess whether they should make any of the many decisions they face in their daily operations. They do not depend on any particular decision for their priorities but are assessed in terms of the goals and values of the individual or organization. Synthesis is made with two formulas, one multiplicative and one additive subtractive that can give rise to negative overall priorities. This paper summarizes and illustrates basic complex decisions involving several control criteria under each of the BOCR merits. Thomas L. Saaty holds the Chair of University Professor, Katz Graduate School of Business, University of Pittsburgh, Pittsburgh, PA, and obtained his Ph.D. in mathematics from Yale University. Before that he was a professor at the Wharton School of the University of Pennsylvania for ten years. Prior to that he spent seven years at the Arms Control and Disarmament Agency in the State Department in Washington, DC, that carried out the arms reduction negotiations with the Soviets in Geneva. His current research interests include decision-making, planning, conflict resolution and synthesis in the brain. As a result of his search for an effective means to deal with weapons tradeoffs at the Disarmament Agency and, more generally, with decision-making and resource allocation, Professor Saaty developed The Analytic Hierarchy Process (AHP) and its generalization to dependence and feedback, the Analytic Network Process (ANP). He is co-developer of the software Expert Choice and of the software Super Decisions for decisions with dependence and feedback. He has authored or co-authored twelve books on the AHP/ANP. Professor Saaty has also written a number of other books that embrace a variety of topics, including Modern Nonlinear Equations, Nonlinear Mathematics, Graph Theory, The Four Color Problem, Behavioral Mathematics, Queuing Theory, Optimization in Integers, Embracing the Future and The Brain: Unraveling the Mystery of How It Works. His most recent book is Creative Thinking, Problem Solving & Decision Making. The book is a rich collection of ideas, incorporating research by a growing body of researchers and practitioners, profiles of creative people, projects and products, theory, philosophy, physics and metaphysics...all explained with a liberal dose of humor. He has published more than 300 referred articles in a wide variety of professional journals. He has been on the editorial boards of Mathematical Reviews, Operations Research, Naval Research Logistics Quarterly, Mathematical and Computer Modeling, Socio-Economic Planning Sciences, Applied Mathematics Letters, and several others. He also served as consultant to many corporations and government.     

变质性产品库存模型研究:延期支付策略或延期交货策略

对于变质性产品的销售,批发商为了减少变质带来的损失以及缩短流通时间,通常会在两种不同营销策略(给予顾客延期支付策略增加市场订购积极性或者采取延期交货策略减少变质损失)中做选择或者采取集成策略.但在实际操作中,如何在这两种营销策略中作出最佳选择是批发商需要考虑的问题.本文分别构建基于延期支付和延期交货的变质性产品库存决策模型,通过对两个库存模型进行分析,给出了最优策略.两个决策模型的最优策略对比结果发现:在其他参数给定的前提下,当产品的售价与进价比偏低时,批发商适合采取延期支付策略;反之,采取延期交货策略.最后利用数值算例分析了相关参数扰动对最优策略的影响,并提出了针对批发商合理制定运营策略的建议.
