回顧台灣的經濟發展軌跡,過去五十年努力以赴快速提升國民所得,逐步邁入已開發國家之林,如今台灣廉價勞力優勢逐漸被東南亞和中國等國家取代,台灣產業也開始朝向高科技、高附加價值產業發展,電子資訊產業為了持續保有全球市場競爭力,開始致力提升企業的產品開發能力,持續進行創新性產品開發,創造企業價值,這是台灣電子資訊產業建立全球競爭力的重要因素之一。 在經濟發展過程中,台灣電子產業致力於產品升級和企業轉型,擺脫複製組裝或OEM(委託生產製造),邁向ODM(委託設計製造)和OBM(自有品牌) ,促使產品研發能力提昇並持續擁有國際競爭優勢,於全球性激烈競爭市場環境中生存,並在全球產業分工模式中佔有一席地位。如何在最短期間推出品質、功能、價格皆能滿足市場需求,以維持其競爭優勢,成為台灣產業界共同關心的課題。 在全球化產業競爭日愈激烈的今日,台灣製造業除了有效運用大陸低廉生產勞動成本的競爭優勢,本身也應該從原有代工製造的型態,發展成具有代工設計能力,並且結合垂直產業價值鏈上的所有廠商,進行產品的協同設計開發,使產業核心能力互相連結,發揮創新的能力。『協同式產品商務模式』若能建立在兩岸三地的經貿合作網路中,則台商可以將企業的各項營運資訊做有效的整合,達成及時溝通互動及智慧分享的目的,將產品的開發時程大幅縮短,同時也可節省不少溝通成本,進而為企業建立競爭優勢。 本研究從產品生命週期管理系統(PLM:Product Lifecycle Management)的用途與發展歷程觀察;台灣電子產業內外部研發職能現況,及企業內部研發活動與外部夥伴組織協同設計面臨的管理瓶頸,還有從企業導入生命週期管理(PLM)系統的目的及期望觀察;關鍵成功因素(CSF) 研究方法運用在PLM專案實施過程中,藉由審視實際個案導入的手法分析企業導入生命週期管理(PLM)系統後;企業內部各功能性組織及外部夥伴組織(客戶及供應商)協同設計活動,透過協同資訊服務網,將企業的各項營運資訊做有效的整合,及時溝通互動及智慧分享,逐項分析企業於策略面、作業面、管理面、組織面、資訊科技面的流程管理改善效益,期待在全球電子科技業分工議題上,藉由資訊科技的整合及溝通,兩岸産業分工由産品生産階段的分工走向研發與創新、營運、製造、行銷等功能性的分工走向,為台灣電子科技業盡一份心力。 / Taiwan’s economic development track shows that the country in the past 50 years bolstered its national income, and gradually becoming one of the developed countries in the world. And now, Taiwan’s once competitive labor is replaced by cheap labor in Southeast Asia and China. This prompted Taiwanese companies to switch to high tech and high value added industries. In their attempt to maintain its competitive edge in world market, Taiwan electronics and IT companies escalated their research and development ability on enterprise products. Creating values through consistent innovative product design is one key factor by which Taiwan electronic and IT industry players compete in the world market. In its economic development, Taiwan electronics enterprises thrived in product upgrading and business transformation. They moved away from assembly production or OEM (Original Equipment Manufacturing) businesses, and move toward ODM (Original Design Manufacturing) and OBM (Own Brand Manufacturing). Improved research and product design capability became their competitive edge in the global market, allowing them not only to survive amongst the cutthroat competition, but also to play a key role in global collaborative markets. It is the common focus of Taiwanese IT companies to keep ahead of global competition by delivering cost effective, quality, feature rich products in the shortest lead time. In face of the increasing competitive the global market today, Taiwanese electronics manufacturing companies bolster their strength by migrating from OEM to ODM businesses, and vertically integrating satellite companies in China, fully leveraging China's cheap labor and low cost resources. This collaborative production and business model, combining the core competence of all industries from both camps, brings out a new creative and powerful force. If this collaborative production and business model can be built on the economic and trade networks across the strait, then, Taiwanese enterprises can effectively integrate all its operational information in the same platform, linking up intelligence databases and interactive, real time communication. As a result, Taiwanese industries can shorten a great deal of product development lead time and reduce communication costs. This brings Taiwan further ahead in global competition. This research aims to layout the groundwork for Taiwanese enterprises to expand from collaborative production to functional collaborations, including R&D, operating, manufacturing, sales and marketing, by analyzing the current workflow management through case study of PLM implementation. This research results shall be supported by the following coverage: 1)Observation on system implementation and progress of PLM. 2)Purpose and expectation of Taiwanese enterprises in implementing PLM (product life cycle management). 3)Current functions of Taiwan electronic companies’ in house R&D units and external cooperative partners. 4)Bottlenecks in managing in house R&D, their activities and their cooperation with external engineering teams. 5)The role of Critical Success Factor (CSF) in the implementation of PLM. 5) Activities of internal design functional units collaborating with alliances, both vendors and customers, utilizing collaborative information service platform to effectively integrate a wide range of cross the strait operations, and linkage of interactive communication channels and sharing of real time knowledgebase database. 6) Analyze the enterprise’s tactics, the operations, the managements, the organization and Information technology aspect to improve their RD workflow management superiority item by item.

協同產品研發生命週期管理之研究-以某個案公司為例 / The Research of Collaborative Product Development Lifecycle Management:A Case Study

粘平吉, Nian,Pyng Jyi Unknown Date (has links)
由微笑曲線理論(施振榮1992年提出)知道企業應該朝高附加價值領域發展,而其中上游智財權(Intelligent Property)、知識經濟(Knowledge Economics)是我國OEM、ODM製造業將生產基地移到大陸後,為避免國內產業空洞化,必須在國內深耕的核心競爭力領域。要強化智財權、知識經濟則必須強化產品研發與創新能力,而產品研發與創新能力的提升必須藉助良好的「協同產品研發生命週期管理解決方案」(Collaborative product development lifecycle management solution) ;但是此解決方案尚在發展初期,不論企業或是個人對於它皆了解不夠,也不知如何利用此解決方案來提升產品研發能力。 因此本研究透過文獻的收集與探討,整理出PLM(Product Lifecycle Management)解決方案的定義、演進,並對PLM解決方案的架構進行探討,再針對市場上PLM解決方案系統廠商所提供的PLM系統產品進行說明,讓有意導入PLM解決方案的公司企業可以參考。另外由於知識管理可以讓PLM系統所收集的產品資料與產品研發經驗與知識得以分享、流通與再創造與加值,因此對於知識管理(Knowledge Management)與PLM的關係進行探討。2003年歐盟立法通過兩大環保法規—WEEE(Waste Electronics and Electrical Equipment)及RoHS(Restriction of Hazardous Substances),要求製造廠商從設計開始即需考慮整個產品生命週期的環境保護觀念,此法規讓產品生命週期觀念有了具體的落實實施,因此本研究亦對綠色環保法規與PLM解決方案的關係進行探討與說明。 本研究為協助企業在導入PLM解決方案前,能夠深入了解PLM解決方案,因此以個案研究方式深入分析個案公司在協同研發產品生命週期中所面臨的問題,並針對這些問題提出PLM系統解決方案的建構策略,也提出PLM系統整合應用架構做為PLM企業策略方法施行的基礎;此PLM系統整合應用架構的特色包括以產品為核心,重視人員、流程及產品資訊;涵蓋從產品觀念的構思開始一直到產品生命結束為止的全生命期間的管理與支援;支援涵蓋跨部門、客戶、設計夥伴與供應夥伴等跨企業間的協同合作。並說明此整合應用架構在協同產品研發生命週期管理中的運作情境,最後再對導入PLM系統解決方案提出規劃重點與想法。 本研究在研究過程中有底下幾點重要發現,特別整理如下: 一、 因為綠色環保法規的規定而使得產品生命週期觀念能落實執行。 二、 PLM是一種企業策略方法,要成功導入必須從人員、流程、資訊科技三方面同時規劃。 三、 由於PLM系統架構的定義不同,且PLM系統廠商所提供的PLM系統解決方案亦有不同功能,企業必須根據自己的需求選擇適當的解決方案。 四、 PLM理念一直不斷變化與延伸,PLM系統已成為製造業不可或缺的系統。 對於後續研究者,本研究建議的未來研究方向如下: 一、 建議對於導入PLM要如何進行變革管理進行研究。 二、 建議對於如何利用知識管理來協助研發創新進行研究。 三、 建議對於PLM解決方案所帶來的協同產品研發績效的影響進行研究。 / Referring to the Smiling Curve Theory (Shih Chen-Rong, 1992), it is realized that enterprise should gradually lead the “High Value-Added” concept to its management system. Since recent years, Taiwan local OEM and ODM factories widely moved their production base to Mainland China, and so in order to avoid domestic industries being emptied, “Intelligent Property” and “Knowledge Economics” must be cultivated deep into our country. On the other hand, prior to strengthen Intelligent Property and Knowledge Economics, the premise is to strengthen the competency of Product Development and Product Innovation. In addition, to enhance the competency of Product Development and Product Innovation must follow by good “Collaborative product development lifecycle management solution”. However, the solution is still at initiation phase, therefore so far as now, either the enterprises or the individuals are not acquainted with it, and also do not know well how to utilize the solution to reinforce the Product Development competency. By means of the concept mentioned above, literatures are collected and investigated by this study to work up the definition and evolution of PLM (Product Lifecycle Management) Solution. In advance, the framework of PLM solution is discussed; and the PLM system, provided by supplier, is introduced by this research as well, in order to allow businessmen, who would like to lead PLM Solution into their organizations, to adopt them as a reference for developing their enterprises. Moreover, considering of that Knowledge Management enables the experience and knowledge of Product Development and Product Information, collected by PLM system, to be shared, circulated, recreated and value-added, the relation between Knowledge Management and PLM system is examined in this study. Also, the relation between the legislated rules of Green Environmental Protection and PLM Solution is researched and reported in response to the two regulations of WEEE (Waste Electronics and Electrical Equipment) and RoHS (Restriction of Hazardous Substances), which were legislated by European Union (EU) in 2003. In accordance with the two statutes, manufacturers are requested to think of the concept of environmental protection for the entire Product Lifecycle, starting from product design begins. For the sake of assisting enterprises in understanding deeply about the PLM Solution, before introducing it into their organization, “case study” access is therefore adopted by the study to analyze in deep the problems on “Collaborative product development lifecycle management solution”, which might be incurred in each individual case. In line with the problems, a constructional strategy for PLM system as well as a framework of the application and integration of PLM system are proposed as a base of executing business strategic approach. Characteristics of the framework of the application and integration of PLM system include “strategic core by product”; “to value personnel, operation flow and product information”; “to manage and support the entire lifecycle from product concept to product lifespan being ended”; “the support covers collaboration between the divisions, customers, designing coworkers, suppliers. In addition, the running situation of this framework, which runs under the “Collaborative product development lifecycle management solution” is presented in the study. In the final part of the research, the key-points and strategies are presented for the proposal of introducing PLM systemic solution. During the researching process, some important conceptions are discovered, and are summarized as follow: 1. Owing to the rules of Green Environmental Protection is legislated, it therefore enables the concept of product lifecycle be executed accurately. 2. PLM is a business strategic approach, so to introduce into enterprise successfully must through a proposal with the factors of personnel, operation flow and information technology simultaneously. 3. Since PLM system has varied system as well as different solution function from different suppliers, enterprises should choose a proper PLM systemic solution based on actual needs. 4. PLM concept varies and extends consecutively, so today PLM has become to the only system for option. Hereunder suggestions from researcher to the latter in future as the researching direction reference. 1. Suggest proceeding study with how to run Reformation Management after the adoption of PLM system. 2. Suggest proceeding study with how to utilize Knowledge Management for assisting in developing innovation. 3. Suggest proceeding study with the subject of “Influence on the results of collaborative product development by PLM systemic solution”.

Die TU Dresden als eine Keimzelle der Digitalisierung im Maschinenbau: Aktivitäten und Erfahrungen in der deutsch-deutschen und internationalen Zusammenarbeit von 1960 bis 2020

Kochan, Detlef 29 April 2021 (has links)
Von Beginn der flexiblen Automatisierung mit numerisch gesteuerten Werkzeugmaschinen und der zugehörigen Programmier-Software bis zum gegenwärtigen Entwicklungsstand (Industrie 4.0) wird die historische Entwicklung von 1960 bis 2020 aus der Position eines aktiven Mitgestalters dargestellt. Interessanterweise vollzogen sich die wesentlichen Entwicklungsetappen für die ersten dreißig Jahre parallel in beiden deutschen Staaten. Aus den Lehren des Zweiten Weltkrieges wurden im Rahmen der UNESCO zum friedlichen Informationsaustausch geeignete wissenschaftliche Organisationen gegründet: • IFIP (Internationale Föderation für Informationsprozesse, speziell Arbeitsgrupp CAM • CIRP (Internationale Akademie der Fertigungstechniker) Mit der Berufung und aktiven Mitarbeit in diesen Organisationen war eine Plattform für die deutsch-deutsche und darüber hinaus internationale Kooperation gegeben. Ein besonderer Schwerpunkt für den geordneten Informationsaustausch im Rahmen der gesamten dynamischen Entwicklung im Gebiet der Produktionsautomatisierung war dabei die im 3-Jahres-Rhythmus durchgeführte Konferenzserie PROLAMAT (Programming Languages for Machine Tools), gestartet 1969 in Rom. Im weiteren Verlauf wurde dieser Begriff viel breiter für das gesamte Gebiet der automatisierten Informationsverarbeitung und Fertigung erweitert. Ein besonderer Höhepunkt war dabei die erfolgreichste PROLAMAT-Konferenz 1988 in Dresden. Parallel dazu erfolgten an der TU Dresden Entwicklungen in Richtung CAD/CAM-Labor und später CIM-TT (CIM-Technologietransferzentrum). Damit war an der TU Dresden 1989/90 ein Entwicklungsstand gegeben, der unmittelbar zu gemeinsamen deutsch-deutschen und internationalen EU-Projekten genutzt werden konnte. Dieses hohe Entwicklungsniveau wurde zur offiziellen Eröffnung des CIM-TT-Zentrums in den Eröffnungsreferaten durch den damaligen Wissenschaftsminister Dr. Riesenhuber und Ministerpräsident Prof. Biedenkopf gewürdigt. Durch die zum gleichen Zeitpunkt verfügte veränderte Nutzung des für das CIM-TT im Aufbau befindliche Gebäude durch die neugegründete Juristische Fakultät wurde der erfolgreich vorbereitete Weg verhindert. Unabhängig davon blieb meine fachliche Orientierung mit den gravierenden Weiterentwicklungen eng verbunden. Dazu trug das Sabbatical-Jahr in Norwegen und den USA 1992 maßgeblich bei. Mit dem Forschungsaufenthalt war die Entscheidungsvorbereitung für die vorgesehene Groß-Investition für das neueste generative Verfahren verbunden. Gleichzeitig mit dem fundierten Nachweis der bestgeeigneten sog. Rapid-Prototyping-Anlage vom deutschen Anbieter EOS München war die TU Dresden auf diesem neuen High-Tech-Gebiet 1992 in einer anerkannten Spitzenposition. Mit meiner Publikation eines der ersten Fachbücher im Gebiet Advanced Prototyping (jetzt Additiv Manufacturing) war darüber hinaus eine gute Basis für weitere innovative Aktivitäten gegeben Dazu gehört die Gründung einer High-Tech-Firma (SFM - Schnelle Fertigung von Modellen) mit bemerkenswerten beispielgebenden Ergebnissen. Hervorgehoben soll die zwanzigjährige aktive Kooperation mit der Universität Stellenbosch (RSA - Republik Südafrika), die unter anderem mit meiner Berufung zum Extraordinary Professor im Jahr 2003 verbunden ist. Mit der Eröffnung eines Technologie-Zentrums nach dem Vorbild des ursprünglichen CIM TT -Zentrums der TU Dresden konnte für Südafrika ein wertvoller Beitrag geleistet werden. Das gesamte Lebenswerk ist gekennzeichnet durch die Entwicklungsschritte von der Mathematisierung über die Algorithmierung bis hin zur Programmierung vielfältiger technologischer Sachverhalte. Die Ergebnisse sind in einer Anzahl von persönlichen Fachbüchern (z.T. übersetzt in das Russische und Ungarische) wie auch Konferenzberichten und mehr als 200 Veröffentlichungen (deutsch und englisch) dokumentiert.

DIGITAL TWIN: FACTORY DISCRETE EVENT SIMULATION

Zachary Brooks Smith (7659032) 04 November 2019 (has links)
Industrial revolutions bring dynamic change to industry through major technological advances (Freeman & Louca, 2002). People and companies must take advantage of industrial revolutions in order to reap its benefits (Bruland & Smith, 2013). Currently, the 4th industrial revolution, industry is transforming advanced manufacturing and engineering capabilities through digital transformation. Company X’s production system was investigated in the research. Detailed evaluation the production process revealed bottlenecks and inefficiency (Melton, 2005). Using the Digital Twin and Discrete Event Factory Simulation, the researcher gathered factory and production input data to simulate the process and provide a system level, holistic view of Company X’s production system to show how factory simulation enables process improvement. The National Academy of Engineering supports Discrete Event Factory Simulation as advancing Personalized Learning through its ability to meet the unique problem solving needs of engineering and manufacturing process through advanced simulation technology (National Academy of Engineering, 2018). The directed project applied two process optimization experiments to the production system through the simulation tool, 3DExperience wiht the DELMIA application from Dassualt Systemes (Dassault, 2018). The experiment resulted in a 10% improvement in production time and a 10% reduction in labor costs due to the optimization

A plm implementation for aerospace systems engineering-conceptual rotorcraft design

Hart, Peter Bartholomew 08 April 2009 (has links)
The thesis will discuss the Systems Engineering phase of an original Conceptual Design Engineering Methodology for Aerospace Engineering-Vehicle Synthesis. This iterative phase is shown to benefit from digitization of Integrated Product&Process Design (IPPD) activities, through the application of Product Lifecycle Management (PLM) technologies. Requirements analysis through the use of Quality Function Deployment (QFD) and 7 MaP tools is explored as an illustration. A "Requirements Data Manager" (RDM) is used to show the ability to reduce the time and cost to design for both new and legacy/derivative designs. Here the COTS tool Teamcenter Systems Engineering (TCSE) is used as the RDM. The utility of the new methodology is explored through consideration of a legacy RFP based vehicle design proposal and associated aerospace engineering. The 2001 American Helicopter Society (AHS) 18th Student Design Competition RFP is considered as a starting point for the Systems Engineering phase. A Conceptual Design Engineering activity was conducted in 2000/2001 by Graduate students (including the author) in Rotorcraft Engineering at the Daniel Guggenheim School of Aerospace Engineering at the Georgia Institute of Technology, Atlanta GA. This resulted in the "Kingfisher" vehicle design, an advanced search and rescue rotorcraft capable of performing the "Perfect Storm" mission, from the movie of the same name. The associated requirements, architectures, and work breakdown structure data sets for the Kingfisher are used to relate the capabilities of the proposed Integrated Digital Environment (IDE). The IDE is discussed as a repository for legacy knowledge capture, management, and design template creation. A primary thesis theme is to promote the automation of the up-front conceptual definition of complex systems, specifically aerospace vehicles, while anticipating downstream preliminary and full spectrum lifecycle design activities. The thesis forms a basis for additional discussions of PLM tool integration across the engineering, manufacturing, MRO and EOL lifecycle phases to support business management processes.
