企業網路資源規劃模型之建立 / Building the Enterprise Network Resource Planning Model郭佳育, Guo, Jia-Yu Unknown Date (has links)
網路科技的演進,解決了許多地域、時間的隔閡,並激發出許多新的應用。在這樣的環境下,資訊部門人員在網路的規劃與運用方面必須要承擔比以往更大的壓力,這些壓力除了來自組織內不斷增加的各式應用需求外,也來自企業外部的客戶及供應商。於是不斷有新的應用被引入企業網路,面對負擔、責任日益重大的企業網路,網路相關業者也紛紛針對企業需求或增進網路效率提出新的解決方案。
本研究嘗試由應用程式部署規劃及解決方案的選用兩方面著手,透過規劃模型的建立,來解決企業在規劃網路資源時所面臨的難題,並以個案的實作來瞭解此規劃模型所能達成的目標以及限制。
研究結果發現,此網路資源規劃模型可達到下列四項目標:
一、使企業瞭解本身網路架構的能力。
二、預估引入新應用程式後的頻寬耗用狀況。
三、評估解決方案對網路環境所造成的影響。
四、瞭解目前企業網路是否足以承擔這些新應用與新方案。

多國企業整合與協調之研究--以宏碁集團之主從架構為例 / The coordination & integration mechanisms of multinational enterprises - the case of Acer's client-server structure許宗哲, Hsu, Tsung-Che Unknown Date (has links)
本研究主要在探討多國企業面對全球環境變化與全球策略的改變時,如何針對不同角色的子公司進行整合與協調。另外,並提出多國企業整合與協調的權變模式,試圖瞭解在不同的全球環境與全球策略下,子公司角色如何變化、資本流與知識流如何移動、應採取何種整合與協調機制。本研究採用個案研究法,以國內國際化程度最深之一的宏碁集團為對象,針對集團總部與六個子公司進行研究,並以 Client-ServerO.X、Client-Server l.X 與 LOB 將宏碁集團整合與協調分為三個階段,兼用結構化問卷與對子公司高階經理的深度訪談取得詳細資訊。另外並椅子公司的「相對優勢」、「全球整合/地方回應」與「策略重要性」將子公司角色分成八類,亦定義出六個整合與協調的機制。研究結果發現,當全球整合壓力增強時,多國企業將增加成本領導策略與與複雜創新策略的權重,優先促使全球整合導向、策略重要性高但相對優勢較低的子公司改變其角色,此時對不同角色的子公司仍需採取不同的整合與協調機制,但皆加強結構調整機制與資源管理機制的使用;當地方回應壓力增強時,多國企業將增加行銷差異化策略與廣度策略的權重,優先促使地方回應導向、策略重要性高但相對優勢較低的子公司角色移動,但較不強調資源管理機制的使用。 / This paper investigate how a Multinational Corporation(MNC) integrates and coordinates subsidiaries with different roles, in the context of global competition . A contingency model MNC's integration & coordination is proposed in order to provide a in-depth understanding of how to deal with the flows of knowledge and capital. Integration and coordination mechanisms are also suggested to manage the strategic role changes of subsidiaries. A qualitative approach consists of questionnaires and interviewing of CEOs is used to explore the relationships among global environment, global strategy, subsidiary's roles and mechanisms to integrate and coordinate the activities of a MNC. One of the MNCs in Taiwan with high degree of internationalization, Acer Group is the focus of the study. The head office and six subsidiaries were interviewed and the following three phases of Acer's history were examined: Client-Server O.X, Client-Server l.X and LOB. Three dimensions, relative advantage, integration/responsiveness and strtrgic importance, were used to classified the roles of subsidiaries into eight categories. We also identified six mechanisms of intrgration and coordinition. The research findings suggest two important patterns to integrate and coordinate. First, increasing pressure to integrate will push MNCs to strengthen the cost strategy and complex innovation strategy, to change subsidiaries'roles. The head office should adopt different integration and coordination mechanisms to deal with subsidiaries with different roles. Two types of the mechanisms, the microtructural arrangement mechanism and the resource management mechanism should be emphasized in all subsidiaries. Second, increasing pressure to response to host demands will push MNCs to strengthen the marketing differentiation strategy and breadth strategy, to change subsidiaries'roles as well.

網際網路資料庫選擇模式之研究 / Internet Database Management and Systems Selection Study謝麗芬, Hsieh, Li-Fen Unknown Date (has links)
最近幾年來,網際網路的出現及應用面的廣泛,改變了企業的資訊架構。從Client/Server擴展到以Web為應用程式的平台,企業面臨了資訊架構的重整,企業網路、電子商務都是現今最新的應用。由於全球資訊網採開放架構,並以HTML、HTTP為標準,使得資訊業者有所依循,開發出許多產品來滿足企業的需求。隨著Web的廣泛使用,應用程式架構、介面與行為特質都將與以往有著大大的不同,元件及交易導向的Web應用程式是勢在必行的路。
對此變革,企業最重要的課題之一是,如何建構完整的企業網路環境以增強競爭力。資料庫系統是企業各種資訊軟體的基礎,在以Web為應用程式的平台的架構下,它仍是其中重要的關鍵元件。選擇資料庫系統必須考慮許多因素,而且現有的資料庫系統的產品很多,各項產品的特性與優點均有不同,每一種產品甚至可再細分成許多元件,可依照需要選用,因此資料庫產品的選擇變成一種複雜的過程。若選擇錯誤則不僅是金錢耗費的損失,更深遠地影響整個企業的順利運作,甚至是企業競爭力的下降,更可能嚴重到影響企業的存續。故資料庫系統的選擇不可不慎。
本文提出一網際網路資料庫體系選擇模式,協助企業在全球資訊網的開放架構及多階層應用系統環境下,評選出符合企業本身狀況及需求的網際網路資料庫系統。此模式內容包含,需求分析與確認、第一至四級網際網路資料庫體系需求屬性之彙整、兩階段的廠商篩選及含加權機制之廠商評比。
最後並將此模式運用於,行政院衛生署藥物食品檢驗局之購置網際網路資料庫設備計劃。 / Internet technology has drastically changed the enterprise computing and platform. Database management and systems represent the core of the change and the key of the new revolution of the information technology and infrastructure. Business information and models have been stored and manipulated through the use of the database technology. Due to the fast growing speed and variety of the database products in the marketplace, managers are having difficult making the right decision in selecting and maintaining the Internet database management and systems.
To tackle this issue, we propose a requirements-based software selection model from the user’s viewpoint. In this research, we develop a five-step choice model with an emphasis on the requirement analysis and rank analysis. We collect and compile the functional and non-functional characteristics and features of the Internet database management and systems. We classify and organize them into a four-layer hierarchy and work with the weight mechanism in the rank analysis. This choice model adopts another five-part rank policy in order to produce the final suggestion of software selection. In the end, we apply the new model in a field case study of the Web Database Systems Procurement Project with the National Laboratories of Foods and Drugs, Department of Health, Executive Yuan.
