都市資訊系統發展計畫執行成效檢核方法之研究

都市資訊系統正隨著國土資訊系統政策之推動，而在各單位間陸續的規劃與建置之中。然而此類資訊系統一般具有投資費用龐大、系統建置時間長、系統技術較新、使用者認知程度不一致等特性。再加上資訊科技日新月異、環境條件變化較大等因素，使得此類系統除了在研擬發展計畫時應加強各項系統評估工作外，於系統發展計畫執行時，更有必要配合執行時程，追蹤檢核系統發展成效，以掌握系統未來進一步發展之方向，並確保系統之投資效益。為有效檢核都市資訊系統發展計畫之執行成效，本文乃以模糊理論與差異量測法為基礎，發展出一套新的檢核方法。文中並將以嘉義縣綜合發展計畫資訊系統為例，進行實証研究。經實証結果可得知，此種研究方法，的確能提供系統執行效益檢核之資訊。研究內容包括：一、前言；二、系統評估方法之回顧；三、系統成效檢核之架構與方法；四、實証分析；五、結論。

Under the national policy of building Taiwan's National Geographical Information System, different government departments are planning and installing their own Urban Information Systems recently. However, this kind of information system are generally characterised with high capital investment, long construction time, frequent technical innovations and inconsistent recognition among different system users. These characteristics, when combined with the effects from the rapid change of information techniques as well as the great variation of the environment, have prompted a fact. The fact is that in order to have better knowledge of future development and to secure benefits from the system investment, except for the emphasis on the system evaluation process in the executing stage, close monitoring and system evaluation during the system running period should also receive considerable attentions. In order to evaluate the effectiveness of a urban information systems, a new evaluation method is proposed in this study on the basis of the fuzzy theory and variation measuring. Technical analysis is carried out under the Chiayi County Comprehensive Plan Information System. It was revealed that the new method is capable of providing information about the effectiveness evaluation of the system. This study consists of five parts: preface, followed by a review of system evaluation methods, a description of the framework and method of the system effectiveness evaluation, these leads to the technical analye, and some conclusions are made upon the results of technical analyses.
