【摘要】 近年来，随着计算机技术、网络的迅猛发展，作为传统行业的服装工业，既面临巨大的挑战，也面临前所未有的机遇。在中国，服装计算机辅助设计(GCAD)已有近二十年的历史，在技术上也取得了长足的进步。然而，目前GCAD系统在中国服装企业的普及率及商业化程度还处于较低水平。而在整套GCAD系统中服装结构图形辅助设计子系统占据重要的角色：它是连接服装效果图形与服装加工的纽带，服装结构图形质量的高低直接影响成衣的穿着效果和舒适感，因此本文将其锁定为研究焦点。 经过近一年对服装企业的调研分析发现：当前，服装结构图形辅助设计子系统主要存在以下三方面原因：缺乏网络化，无法与外界设计资源交流与共享；缺乏智能化，无法利用以往设计经验指导设计，设计效率较低；商业化程度较低。因此，如何在分布服装企业内部及外部构造一个异地并行设计环境，实现服装结构图形数据共享与交流，并最终实现协同设计；进一步提高服装结构辅助设计系统的智能化程度，同时提高整个GCAD系统的商业化程度，是服装结构辅助设计系统的技术研究与应用的新挑战。通过以上分析，本文提出了一种新型的服装结构图形辅助设计平台——基于AutoCAD的网络化、智能化服装结构设计平台。为未来服装结构辅助设计系统的发展提供了一个良好的参考模型。本文的主要研究内容及成果如下： (1)在详细、广泛的市场现状调研及理论研究的基础上，提出了基于AutoCAD软件平台的网络化、智能化服装结构设计平台方案：由既相互独立，又彼此关联的基于Web的服装结构图形设计子系统和基于AutoCAD的智能服装结构图形设计子系统组成。两子系统之间通过AutoCAD物理相连，且由各自的数据库逻辑关联。 (2)在系统开发中，以AutoCAD为软件开发平台，采用两层Clie而serve:结构与三层Browser/server结构相结合的总体体系构架，并结合离线与在线数据库实现服装结构图形及相关数据的管理与维护。 (3)以分布式产品数据管理理论(P DM)为依据，提出了基于Web的服装结构图形设计子系统的整体结构及功能模块划分。 (4)运用web数据库技术、三层B/S实施技术、ASP技术及其远程数据库访问组件ADO等技术，实现了基于web技术的网络数据库远程访问，服装结构图形文件及相关信息的存储、图形数据传输安全，专业信息交流，项目管理，并实现了服装图形协同设计。 (5)在基于实例推理(CBR)原理及服装结构图形设计特点—强经验性的基础上，选用CBR为基于AutoCAD的服装结构图形设计子系统的解决方案。创造性的将点位移及矢量法膜糊推理原理和Bezier曲线算法相结合，设计了实例重用和实例修正算法。为GCAD系统研发企业提供了一个很好的参考模型。 (6)在研究了ARX应用程序的运行环境、运行机制及MFC动态链接库编程接口技术的基础上，在两层C/S结构下，利用objeetARX 2000为AutoCAD二次开发工具，实现了ARX应用程序与AutoCAD风格一致的可视化人机交流界面，并初步实现了部分服装结构图形的智能修改。 最后，本文对课题进行了总结，并对课题未来发展进行展望。更多还原

【Abstract】 With rapid speed development of computer science and Internet, garment industry, as traditional industry, is confronted with not only tremendous challenges, but also unmet opportunity before. In China, GCAD (Garment Computer Aided Design) has almost 20 years history and also make great progress in technology. However, currently popularization and commercialization degree of GCAD is still in comparatively low stage. Especially, Garment Structure Graphics Computer Aided Design (GSGCAD) subsystem plays quite important role in complete GCAD system. Garment structure graphics is a connector between garment appearance graphics and garment making. The quality of garment structure graphics directly makes effect on garment suitability and comfort. Therefore this paper focuses on GSGCAD.After almost one year research and analysis on Chinese garment enterprises, finding that there are three main issues in GSGCAD: lack of network/Internet oriented, cannot sharing and communicating garment structure graphics design resource with outside world; lack of intelligentization, cannot use former design experience as reference, leading to low design efficiency; low commercialization degree. So how to build up a parallel design environment inside and outside a distributed garment enterprise to realize garment structure graphics data sharing and intercommunion, moreover finally realizing cooperative work; improving intelligentization of GSGCAD system; enhancing commercialization of the whole GCAD, hereinbefore all are newchallenges for technology and application of GSGCAD system. Whereas analysis before, this paper brings forward a brand new style GSGCAD platform-Based on AutoCAD, Internet-Oriented, Intelligent Garment Structure Graphics Design Platform, which could be a favorable reference model for future GSGCAD development. Main research contents and outcomes are as follows.i) Based on detailed and extensive garment market research and relative theory, this paper puts forward Based on AutoCAD, Internet-Oriented, Intelligent Garment Structure Graphics Design Platform, which is composed of two subsystem: Based on web Garment Structure Graphics Design subsystem and Based on AutoCAD Intelligent Garment Structure Graphics Design subsystem. These two subsystems are independent one another and associate with each other. They are physically connected through AutoCAD and logically cohered by respective DB.ii) In the process of system development, utilizing AutoCAD as development platform to build up a Client/Server and Browser/Server cooperative system infrastructure and combined with off-line and on-line DB to implement management and maintenance of garment structure graphics and relative data.iii) According with Distributed PDM (Product Data Management), the paper brings forward whole structure and function module partition of Based on web Garment Structure Graphics Design subsystem, iv) Making use of web DB technology, three layer B/S implement technology, ASP, teleDB accessing component ADO and other technology realize web DB long-distance accession, storage and safety transmission of garment structure graphics and relative data, intercourse of professional information, project management and garment graphics cooperative design.v) Based on CBR (Cased-Based Reasoning) principle and characteristic of garment structure graphics design-strong experience-oriented, this paper selects CBR as the basic theory of Intelligent subsystem, which creatively combines point-grading, vectorgraph method, theory of fuzzy reasoning and Bezier curve algorithm together and devise case reuse and revise algorithm.vi) After researching on operation environment and mechanism of ARX application program, interface technology for connecting with MFC DLL, utilizing ObjectARX 2000 as AutoCAD reprogramming tool to implement human-machine interactive interface same style as AutoCAD, moreover primarily realizing part of garment structure graphics intelligent revise.Finally, summarizing the whole paper, prospecting future development a更多还原
