离散优化与连续优化的复杂性概念

问题的复杂性概念起源于离散的图灵计算机理论的研究,在离散优化问题的研究中被广泛的接受.近期连续优化领域的很多文章中提及NP难这个概念.从而来对比介绍离散优化和连续优化研究中这两个概念的差异.

复杂性信息系统需求管理问题研究

在项目管理领域知识的发展包括开发越来越多的过程、工具和技术。关于将使用哪些资源以最有效的方式实现项目目标的决定取决于项目的特定特征，例如目标、资源和环境。这些功能中最具挑战性的功能之一就是项目的复杂性。对大多数管理人员而言，项目的复杂性可以通过其新颖程度，相互依赖性和所涉及的技术以及其他变量来衡量。对于某些管理者而言，复杂性的概念带有主观含义。本文对于相关领域科研工作者和同行业工作人员具有十分重要的参考意义。

浅析复杂性概念在服饰文化中的表达

本文从社会的发展多元化入手,通过服装内涵、服装特点、服装识别等角度分析阐述古代和近现代服饰所表达的复杂性概念的特点,提出服饰文化表现特征在历史演绎过程中存在着片面性、动态特征和不确定性等复杂性特征。认为复杂性的基本问题是"在复杂性空间中寻找最优或约定解",指出认识服饰文化中复杂性概念的表现,可帮助设计者跳出认知事物的表象,关注其相互间的联系,由此探寻设计规律,为服装设计由抽象到具象的设计过程提供有力的理论依据,为设计者的创新活动提供机遇。

试论言语折回修补

本文基于英语口语语料库,讨论话者言语自我修补中的折回修补,对其进行了分类,提出了功能词吸引假设,并用Levelt的合格性规则解释了折回修补各策略的句法并列关系,指出概念复杂性是造成该修补的认知动因之一。同时,对话者进行折回修补的动机进行了探讨。

Introducing Sustainability Concepts Into University Curricula Through Systems Thinking

The aim of this paper is to explore the major issues involved in introducing sustainability concepts into university curricula in an interdisciplinary manner, through Systems Thinking. It is generally accepted that a holistic approach is essential in sustainability studies, but teaching such a new and complex topic to a diverse student population is by no means easy. In this study, sustainability is viewed in the context of Systems Thinking, particularly in Complexity Management domain. A general framework is proposed with the intension of guiding potential instructors who are planning to teach sustainability through Systems Thinking. The framework includes only the suggested systems-oriented material and a review of some system methodologies; it does not cover sustainability issues. Methodologies known as System Dynamics and Soft Cybernetics are explored and emphasized particularly in the paper due to their importance. The framework is kept general enough so that it appeals to students and instructors with a variety of background.
