基于约束参数化的设计技术研究现状分析 总被引:5,自引:0,他引:5
系统分析了基于约束的参数化设计技术的研究现状。首先指出早期CAD系统初级参数化的主要缺陷;根据参数化设计方法在不同时期的主要特点,回顾了参数化设计的发展过程。参数化方法被划分为程序参数化、在线交互参数化和基于自组织方式的离线参数化。在在线交互参数化方法中,重点探讨了初等方法、变量几何法、人工智能法和构造过程法的原理和特点,并在人工智能法中介绍了基于知识的几何推量法、基于自由度分析的约束传播法和基于神经网络的自学习法;给出基于自组织方式离线参数化方法的主要步骤和特点。最后阐明了各种参数化方法存在的问题,以及该技术将来的发展方向。 相似文献

虽然众所周知英国是现代设计思想的起源地之一,也是最早发展设计产业的国家之一,但是综合其设计的发展历史、经济及技术的演进过程分析可以发现,其选择发展设计产业反映的是国家产业发展战略的再定位,即在丧失了技术及经济竞争优势后的产业结构调整。通过了解其设计产业的发展路径,可以使我们在发展设计产业的过程中,不局限于对其实践的学习与借鉴,更能够深入思考与我国优势和发展阶段特点相结合的设计产业定位。 相似文献

Consilience offers a powerful mechanism for borrowing from other disciplines, thereby extending the scope of what can be known. This paper looks at the foundations of the activity of design as a means of providing IT systems that cater for diverse needs. Developing systems that are expected to satisfy needs continuously (i.e., systems that are expected to evolve) calls for a dynamic activity of design that is responsive to changes in the environment. The contrast with the scientific assumption of ordered development invokes a new classification, supported by insights from other disciplines that place the range of approaches in context. Design is neither orderly nor linear; it implies a continuous and active search to resolve trade-offs and satisfy changing constraints. The paper concludes by making a case for design as an alternative culture that borrows from, and supports, both the scientific and the literary cultures. Acceptance of the role of practice as an interface alongside the more traditional cultures enables researchers and practitioners to access and adopt a larger variety of methods and general approaches underpinning an even larger corpus of insights. Consilience can occur at different levels and offer a variety of benefits. Balancing scientific enquiry with artistic flair and creativity through careful sensemaking that supports sharing across cultures provides the greatest benefit from learning to look across rather than blindly focusing inwards. 相似文献

“人性化设计”的到来标志着工业设计进入了一个新的发展时期。关于人性化设计我们会有不同的理解,而各个国家的优秀设计师们也用他们的创意在阐释着这个设计时代的新主题。最近网上比较流行的韩国小设计给了我很大的启发。他们如中国古时精于写意的书画家,能够把原本不起眼的虫虫草草描画得栩栩如生,焕发出不一样的生机。本文以几个很普通但很不俗的小设计作为切入点进行论述,于设计的细微处去发掘人性化设计的意义之所在。 相似文献

Synchronous e-learning has received much less research attention, as compared with asynchronous e-learning. Practitioners that consider using and designing synchronous e-learning are in urgent need of guidance. In order to address this need, we propose design exemplars for synchronous e-learning. They are directed towards a primary constituent community of teachers, administrators, managers and developers of e-learning. The exemplars have been theoretically as well as empirically grounded through cross-case analyses of studies conducted between 2003 and 2006. Moreover, the exemplars have been evaluated by conducting focus group sessions with experienced practitioners having experience of using and developing e-learning. Strong support was identified for each design exemplar. The exemplars can be used as research hypotheses and be tested in future design research. 相似文献

UMLDiff is a heuristic algorithm for automatically detecting the changes that the logical design of an object-oriented software system
has gone through, as the subject system evolved from one version to the next. UMLDiff requires as input two models of the logical design of the system, corresponding to two of its versions. It produces as output
a set of change facts, reporting the differences between the two logical-design versions in terms of (a) additions, removals,
moves, renamings of model elements, i.e., subsystems, packages, classes, interfaces, attributes and operations, (b) changes
to their attributes, and (c) changes to the relations among these model elements. In this paper, we detail the underlying
metamodel, the UMLDiff algorithm and its heuristics for establishing lexical and structural similarity. We report on our experimental evaluation
of the correctness and robustness of UMLDiff through a real-world case study. 相似文献
