【摘要】 随着Internet技术,特别是制造业网络化技术的迅猛发展,产品网络化协同开发技术已成为现代制造企业提高产品开发能力和市场竞争能力的重要发展战略之一。当前,国内外许多专家、学者和企业正在对该领域开展深入的研究,取得了许多重要的成果。然而,目前该领域的现有研究主要集中在产品网络化协同开发方法和具体技术方面,在产品网络化协同开发的工作模式和过程控制方面的研究还远不够。为此,论文从产品网络化协同开发的基本原理、方法和相关技术等方面,对产品网络化协同开发系统(Networked Product C ooperative Development System, 简称为NPCDS)的工作模式及其产品开发系统的过程控制进行研究。论文首先以产品网络化协同开发系统为研究对象,分析了产品网络化协同开发系统的产生背景和开发过程。阐明了产品网络化协同开发系统的基本内涵和特征,并对与论文研究主要相关领域的国内外研究现状进行了综述,明确了论文研究的方向、目的和意义。论文提出了一种多因素综合优化NPCDS的实施策略和方法,该方法从任务层、活动层和交互层三个方面研究了产品网络化协同开发系统(NPCDS)的工作机理,从而给出了基于时间、基于设计过程和基于设计对象的实现NPCDS的三种工作方式。同时,论文对企业产品开发资源、产品开发决策过程、产品开发设计过程、产品开发制造过程和产品服务等方面的有机集成进行了研究,提出了一种适应于产品全寿命周期管理的产品网络化协同开发系统的全过程集成模型,建立了产品网络化协同开发系统的应用模式。在产品网络化协同开发任务的分解与分配技术方面,提出了基于协同维度、任务分配度和最大分配度原则的任务分配方法,建立了按产品功能划分任务、按照产品组成单元划分任务、按照产品开发过程划分任务和按照产品开发资源划分任务的4种方式。提出了一种基于知识、方法和关系为工作单元的信息处理统一模型,该模型能有效表示信息的转换和处理过程,将该模型用于产品开发过程的信息流控制与管理,从而建立了产品网络化协同开发系统的多级递阶控制结构和过程控制模型,并针对NPCDS的过程控制目标建立了短作业信息反馈、开发过程信息跟踪和信息资源优化的产品开发控制策略。 最后以论文提出的 NPCDS 的思想、理论和方法为指导。建立了 NPCDS 环境下,野营水处理装备开发的总体结构、协同工作方式和业务管理模式,构建了产品网 III<WP=6>中文摘要络化协同开发系统的原型,并成功地应用于野营水处理装备的开发,验证了该系统的可行性和实用性。更多还原

【Abstract】 Along with the rapid development of Internet technology, as well as network-basedmanufacturing technology, Networked Product Cooperative Development Technology(NPDCT) has become one of crucial development strategies by which modernmanufacturing enterprises enhance product development and improve the competence tocompete with others in market. Nowadays, many of experts, scholars and enterprises havebeen carrying out researches about NPDCT in depth, and obtained many importantachievement. Nevertheless, existing researches are mainly concentrated on the techniqueand relative technical aspects of NPDC; however, the exploration of working pattern andprocedure controlling is fairly few, consequently, which affects popularization andapplication of the Networked Product development style in enterprises. Therefore, thecore content of the thesis will explore the working pattern and procedure controlling ofNPCD.A kind of system named Networkd Product Cooperative Development System(NPCDS), which is the combination of network communication technique. Datamanagement technology as well as product processing procedure, is put forward in thisdissertation, on the basis of analyzing market environment and manufacturingcircumstances confronted with by manufacturing and by combining with presentdevelopment of company products as well as the deep effects upon product developmentbrought about by manufacturing information-based. Furthermore, a kind of productdevelopment pattern is also put forward in this dissertation. By taking advantages of thiskind of advanced product development pattern called NPCDS, product developmentresources of company can be used efficiently, the ability of marketing and management,and product development of companies be strengthened, product quality and marketfeedback capability be enhanced, overall profits be increased. Networked Product Cooperative Development System is firstly regarded as theresearch object in this dissertation, then analyzing its background and developmentprocess, illustrating its basic connotation and character, analyzing the research status ofour country and abroad, confirming the research direction, objective and sense, andintroducing the research source which supports the content in this dissertation.On thefoundation of the analysis of modern advanced manufacturing technology, the workmechanism of NPCDS is firstly illustrated in this dissertation, bringing forwardimplement strategy and optimization method, presenting three methods which are based III<WP=8>英文摘要on time, design process and design object to implement NPCDS, establishing the theoryfoundation for enterprises using NPCDS to develop products, putting forward a NPCDSworking model based on life-cycle management which is the integration of productdevelopment resources ,product development decision-making process, product designprocess and product manufacture process. On the foundation of these, the applicationpattern of NPCDS, is also mentioned in this dissertation, which makes good conditionsfor the enterprise using the system in the product development project, brings forward amethod and strategy based on manufacturing resource classification and manufacturingresource information for enterprise making alliance which is a good measure for buildingthe NPCDS organization, puts forward an asynchronism product data-changing methodbased on STEP and a synchronization product data-changing method based on XMLwhich solve the problem of information share and change of NPCDS. The four taskassignation ways of product development are given. A unified model of informationprocessing on the base of the integration of relation, technowledge and method be putforwarded creativity, and the above model be applied in control and management ofinformation flow during the process of product design. The control strategy ofinformation feedback, information trace and information resources optimization beextracted.更多还原
