科技的演進可能改變了人們的生活行為。隨著智慧型手機的快速成長，數位敘事將會以一種嶄新的方式產出行動內容。我們透過互動設計的元素以及「行動敘事」的特性為依據，設計了一個無所不在的「行動協作數位敘事平台」，以促進這個改變能實現。利用這個平台，使用者根據他/她的所在地，不僅可以下載閱聽附近的行動內容，並且可以增修或記錄周遭的事物後上傳。我們並加進「協作」的功能到此平台，以提昇內容的多元與豐富，使得閱聽者，更能夠沉浸在敘述的內容當中。除此之外，本平台也增進網路技術，使其可以在離線時仍然可以持續記錄與協作內容，不受時空限制。 我們建置了這個平台以APP的型式在Android系統上呈現，並作田野實驗，以研究此新的行動協作敘事型態。我們針對平台進行兩個部分的評估與分析，其一為使用者介面的評估，我們以放聲思考法進行，並隨後對介面做出修正；其二為平台系統使用評估，此部分以訪談法進行，並同時與系統Log作比對驗證。平台實驗發現的設計元素以及使用行為，希望可以在未來對此領域欲進一步研究者，提供很好的建議。 / Technologies could change users’ behaviors. As the recent growth of mobile smartphones, digital narrative would have a new way to create mobile content. Through interactive design components and features of “mobile narrative”, we design a "Mobile Collaboration Digital Narrative Platform" to facilitate this change. A user can retrieve nearby mobile content, and also have the ability to add, edit or record what is happening at his/her present location. By adding the feature of “collaborative content creation” to the platform, the content can be made more diverse and rich and the reader can better immerse him or herself in it. Moreover, by the enhanced network technology, the platform can also work in offline mode to make it function ubiquitously. In order to study the new type of mobile collaborative narration, we develop the system (an Android App) and do field trial. We evaluate and analyze the system for two parts: one for the assessment of the user interface, and the other for system usage evaluation. We use the think aloud method for the former to amend interface design. For the latter, we interview with users, which are also compared with the system log for justification. The design components and the results for usage behaviors that we found from the new platform will provide a good recommendation for future further study in the field.

當發生大規模地震或強烈颱風等大型天然災害，其災後72小時為人命搜救之黃金期。由歷來的大型災變中，可知行動通訊系統其實極為脆弱且不可靠，而通訊系統癱瘓將影響救災工作之成效。本論文中探討的應急通訊系統利用倖存之連通基地台和斷訊卻沒有損毀的基地台，以無線電互相連接成一個轉送拓樸以建構臨時性通訊系統，稱為應急蜂巢式行動通訊網路(Contingency Cellular Network，CCN)。 在災難發生後，災區通常有許多須要較高通話需求的關鍵區域，其通話需求遠高於輕度災區，建置CCN時必須優先保障其通訊需求，我們先前之研究所提出的樹狀轉送拓樸其結構較脆弱，若任何一個link斷訊失去轉送功能，則其節點以下的使用者通訊將受到影響，導致任何一個節點對外通訊能力非常脆弱，影響CCN之可用度。為了提升CCN之可用度，我們提出了多路徑的CCN網路拓樸解決方案，在本方案中，每個關鍵區域都有數條對外通訊的連線。 本論文以各基地台通訊範圍內的通訊需求人數與災區毀損程度，作為效益參數，在有限緊急修復資源下，將問題塑模為一個類似K-Maximum Spanning Tree問題的Length Bounded Disjoint K-Path Max-Profit Mesh問題，我們證明它屬於NP-Hard問題，並且提出快速且效能不差之啟發式演算法，可在緊急時建立應急蜂巢式行動網路的多路徑網路拓樸。本文以電腦模擬方式，進行實驗以驗證我們的模型之適切性，並評估多路徑拓樸可提升之CCN可用度，實驗結果可提供使用者依不同的CCN可用度及總救災效益需求，選擇所需之多路徑數量。 / When stricken by a catastrophic natural disaster, the golden 72 hours is very critical to life saving. However, communication systems including cellular networks often crashed due to various causes making big impact to the efficiency of disaster response. Our research proposes the Contingency Cellular Network (CCN) by connecting disconnected base stations together using wireless links to form an overlay Ad Hoc network over a disconnected cellular network. 　　In our previous study, we proposed a tree topology to construct CCN, which is vulnerable since a single link failure may have a big impact to the availability of CCN. This thesis proposes a multi-path topology to enhance the availability of CCN such that the selected critical areas will have redundant communication paths connecting to the core network and thus, have higher resiliency against link failure. We model the CCN Multi-path Network Topology Design problem into a combinatorial problem, called Length Bounded Disjoint K-Path Max-Profit Mesh Problem. We take the degree of emergency and the population of each stricken area as the priority measure as well as the amount of emergency recovery resources as the capacity constraint in the topology computation model. The problem is proven to be NP Hard. Therefore, we designed an efficient heuristic algorithm (HLBDK) to solve the problem when it is needed in urgent. Finally, we evaluated the proposed algorithm by simulation. The simulation results show that the average performance deviation of the proposed heuristic algorithm away from the optimal solutions is smaller than 7% in all cases. A significant improvement in the availability can be obtained by using multi-path topology at a reasonable performance degradation. Our research results provide users a fundamental base to determine their availability requirement at a countable performance degradation.

因應行動政府的發展趨勢，美國、加拿大、印度、阿拉伯聯合大公國、我國政府都相繼提出發展行動政府網頁時的設計準則，然而各國政府所提出來之行動政府網頁設計規範相當混亂不統一。因此，本研究將各國政府單位所提供行動網頁設計準則統合整理成七大面向共46條的設計準則。另ㄧ方面，過去許多有關網站設計準則之相關研究，大多使用問卷了解使用者感受，皆無法判斷其準則對資訊尋求的真正影響。因此，本研究以臺北市政府觀光傳播局建置之「臺北旅遊網」為資訊尋求實驗網站，以程式記錄器記錄使用者在執行資訊尋求任務時，實際使用準則之行為歷程記錄為客觀資料，以及資訊尋求任務完成後所進行使用者認知行動政府網頁準則對於資訊尋求之重要性問卷調查為主觀資料，探討影響行動政府網頁資訊尋求速度與資訊尋求完成度之主要準則為何，以作為行動政府網頁設計之考量，以提升網站之資訊尋求效能。 本研究之研究結果顯示：(1)合計有七項使用者無法實際操作卻被認知重要之行動政府網頁設計準則；(2)合計有九項使用者可實際操作之行動政府網頁設計準則，可用操作次數預測資訊尋求達成度；(3)合計有十四項使用者可實際操作之行動政府網頁設計準則，可用操作次數預測資訊尋求速度；(4)合計有十項使用者可實際操作之行動政府網頁設計準則於資訊尋求時頻繁被使用，並且具有一定重要性；(5)合計有四項使用者可實際操作之行動政府網頁設計準則有助於提升同時提升使用者資訊尋求速度與達成度；(6)使用者資訊行為研究有必要以問卷及使用者行為記錄並行評估。 最後，本研究考量可實際操作之行動網頁設計準則之實際使用歷程操作狀況、資訊尋求時間、資訊尋求完成度及受測者認知準則重要度之行為特性，透過SOM分群方法歸納出七群影響資訊尋求速度與達成度之準則特性，並據此提出對於行動政府網頁設計者，使用準則時之參考依據，亦提出未來可供繼續探討之研究方向。 / To cope with the development trend of mobile government, the USA, Canada, India, United Arab Emirates, and domestic governments have proposed the design criteria for developing mobile government information webpage. Nevertheless, the design specifications of mobile government information webpage are chaotic and not uniform. For this reason, design criteria of mobile information webpage provided by various governments are integrated into 7 dimensions and 46 articles in this study. On the other hand, most past research on web site design criteria tried to understand user experience with questionnaire survey, which could not really judge the effect of the criteria on information seeking. As a result, “Travel Taipei”, established by Department of Information and Tourism, Taipei City Government, is utilized as the experimental web site for information seeking in this study. Programmable recorders are used for recording user behavior course of the criteria for information seeking as the objective data; and, the questionnaire survey of users’ perceived importance of the criteria of mobile government information webpage to information seeking as the subjective data. It intends to discuss the major criteria for the information seeking speed and information seeking completion of mobile government information webpage for the design of mobile government information webpage to enhance the information seeking efficacy of web sites. The research results are concluded as following. (1) There are 7 design criteria of mobile government information webpage which are not actually operated by users, but are considered important. (2) There are 9 design criteria of effective mobile government by predicting information seeking completion with operation behavior. (3) There are total 14 design criteria of effective mobile government by predicting information seeking speed with operation behavior. (4) There are 10 design criteria of mobile government information webpage which are used by most users for information seeking and present certain importance. (5) There are 4 design criteria of mobile government information webpage which could simultaneously enhance information seeking time and completion. (6) It is necessary to study users’ information behavior with questionnaire survey and user behavior records for the evaluation. Finally, the behavior characteristics of information seeking completion, information seeking time, and participants’ perceived criteria importance in the actual use of course operation of mobile information webpage design criteria which could be actually operated are taken into account in this study. Seven criteria characteristics to influence information seeking speed and completion are organized through SOM clustering, and, based on which, reference for the use of criteria are provided for mobile government information webpage designers and future research directions.

Such model helps enterprises to define how to create, transfer value to customers, which belongs to the early stage of the business development planning. Then, enterprises start to consider what activities the enterprises have to implement base on the positioning result of Business Model. By combining with the company’s unique key success factors, the proposed analysis framework is more systematic and plays a key role in the long-term development of the enterprises.

隨著科技進步，基於機器學習技術的資料分析工具在顧客關係管理領域已被廣為使用。過去的相關研究文獻大多著重於高交易頻次、與客戶互動頻繁的產業，諸如金融、電信、零售業等，但對於具有相反產業特性的服務業等則是缺乏著墨。本研究希望透過案例研究的方式，完整呈現企業如何實際將基於機器學習技術的資料分析工具應用於顧客關係管理業務的過程，以及這些新技術如何幫助企業提升顧客關係管理的成效。本案例使用行動研究方法來歸納、分析、整理整個專案的過程與結果，文末總結本案例於作業、管理以及策略層面的管理意涵與建議。本研究使用的資料來源為台灣一間大型汽車經銷商的資訊部門與其旗下的服務廠，總共包含了約273萬筆資料。利用於微軟Azure平台上的決策樹模型分析資料，產出高購買機率的顧客推薦名單，服務廠的技師可以針對名單上的顧客推銷，不僅能有效提高推銷的成功率，節省第一線技師的時間，還能夠提升技師以及顧客的滿意度。最後本研究的結果顯示，運用機器學習技術產出的推薦顧客名單，確實能夠幫助本案例公司於顧客區隔以及顧客發展，並達成更有效的顧客關係管理。 / Data-mining tools and machine-learning techniques have long been used in customer relationship management (CRM), including for customer retention in the financial, retail, and telecommunications industries. However, research on machine learning for CRM in service industries remains rare. Accordingly, this paper uses action research to arrive at a holistic understanding of the process of applying machine learning-based data mining in a specific service-sector business, and whether, how, and how much these novel techniques can help it improve its customer relationships. Key areas of interest include operational, managerial and strategic decision-making processes. Based on approximately 2.73 million rows of data collected from a large car dealership’s IT department and its vehicle-maintenance plants, Microsoft Azure’s boosted decision-tree model generated lists of recommended customers. Such lists could be used by the company to increase the success rates of its promotional activities and to decrease both the overall duration and frequency of technicians’ involvement with promotion. This in turn could lead to more efficient and effective frontline operations, and increased satisfaction not only among customers but also among technicians. In short, machine learning-based recommended-customer lists helped the company achieve more effective CRM through better customer segmentation and customer development.

隨著科技不斷地進步與網際網路的日益普及，消費者手中的智慧型手機似乎早已不限用於傳統的通話功能。作者在十幾年前就曾幻想過，如果將來出門在外身上可以只攜帶一支手機，那該有多好。沒想到當初天真爛漫的想像，轉眼幾年後便已幾乎實現。隨著相機、手電筒、地圖、筆記本、隨身聽……等等逐一被我們放進智慧型手機裡，手機已經不再只是手機。而近年來大眾開始把「錢」放進手機，許多企業也紛紛推出「結合手機與錢」這種概念的各式產品與服務。當供給端與需求端都已出現時，行動支付產業就此產生。 行動支付有許多應用與模式，本研究主要針對兩個以即時通訊應用程式為初始業務的案例―微信以及LINE進行探討。兩家案例公司都是在原有業務成長至一定規模後，開始發展新興行動支付業務，分別為：微信發展微信支付，LINE發展LINE Pay。本研究不僅透過資料瞭解這兩個案例之發展歷程、營運模式以及現況；同時藉由策略行銷4C理論架構，逐步分析這兩個案例是如何各自處理交換關係中的四個成本。 研究結果發現，歷經了差不多的光陰，兩個案例所呈現出的現況卻是天壤之別。儘管兩者因為政治環境、市場規模，以及所面對之消費者習慣上的差異，導致經營成效有所落差。不過排除這些先天因素，微信支付相較於LINE Pay，確實於各階段將4C策略執行地更加完善，並因此推動4C良性循環。LINE Pay本身對於4C架構仍有許多進步空間，本研究最終建議LINE Pay可以參考微信支付部分作法，並針對台灣市場適度調整，期許LINE Pay能順利啟動4C良性循環，為自己創造長期競爭優勢。 / With the advances of technology and the popularization of the internet, nowadays smartphones can perform several functions besides communication (e.g., camera, flashlight, map, notebook, Walkman). Moreover, people begin “putting” the money on their smartphones in recent years. Many corporations have also launched new products or services featuring the combination of mobile phone and money. As the growth of both supply and demand in the market, the mobile payment industry has gradually formed. There are many kinds of application and models in the mobile payment industry. This thesis concentrates the attention on two instant messaging companies―WeChat and LINE. Both companies began expanding mobile payment business―WeChat Pay and LINE Pay―after their original business grew mature. This thesis not only reviews the development history and business models of two companies, but also uses the 4C analysis framework to analyze how they dealt with the four transaction costs. The study shows that the operating results of WeChat Pay and LINE Pay are very different. There is still room for LINE Pay to grow. Although WeChat Pay and LINE Pay face quite distinct political environment, market size, and consumers, the thesis suggests that LINE pay can refer to the strategies and methods of WeChat Pay, and make some adjustments so as to successfully create the positive 4C cycle and long-term competitive advantage.
