摘要: | 現今面對重大水利問題時,需要有系統且充足的資訊作為決策之依據。然而隨著資訊的進步,如何即時收集和傳遞足夠的資訊且讓決策者作出較好的決策已成為支援決策資訊之迫切課題。於是本研究提出用於防災應變的支援決策架構( D-Cloud)來解決此問題,此架構採用標準化的影像格式來傳遞資訊,且透過統一的介面格式呈現來提升系統使用性,目的是希望決策者能方便的迅速瀏覽且比較各個資訊,除此之外,透過D-Cloud提供的雲端運算可讓決策者透過不同類型的行動裝置同步及非同步地搜索資訊,且系統使用本地端快取機制讓決策者能隨時隨地、甚至在無網路連線的環境下也能參考最近期的資料。本研究透過iPad實作出適用於D-Cloud的使用者介面,透過實作實際驗證其可行性,並透過三位防災應變專家實際操作的結果發現D-Cloud能提供即時有效的資訊且能更彈性的適用於各種不同類型之平台,故確實改善了傳統的支援決策系統之概念。本研究規劃出應用於防災應變之影像式支援決策系統之架構來提升資訊傳遞及防災應變之效率,並透過實作範例驗證其可行性,且讓未來研究者能依據本研究實作出更完整的防災應變系統。 Information plays a critical role to facilitate making right decisions especially to response the disasters. With the rapid-development in sensing and communication technologies, collecting and transferring a great amount of data is not critical as usual. However, it becomes more challenging to organize and distribute the rich information to the decision-makers to support timely and high-quality decisions. In this research, we proposed a framework D-Cloud to deal with the problems. In D-Cloud, information is tailored to a predefined image format. The images with unified layout enhance the usability of the information. Decision-makers can browse, compare and interpret the information in a short amount of time and with less effort. D-Cloud includes a cloud-computing environment, which allows users to synchronously and asynchronously retrieve the information using varied mobile devices. With the local memory cache in the device, the users can always refer to the latest information even without the Internet connection. We implemented a D-Cloud viewer in iPad to demonstrate the working processes and demonstrate to three experienced decision-makers who have participated in the disaster response processes. From their feedbacks, we found that D-Cloud is superior to the traditional decision-support systems. It can provide more robust services during tough circumstances and can serve as more versatile roles using different devices. In short, we have preliminarily verified the feasibility of using D-Cloud in disaster response. Future researchers may follow the work to implement a more complete system support timely disaster responses. |
