延伸可靠度評估方法至彈性評估問題

為了解決Civil Engineering ra的問題,作者蘇意筑 這樣論述:

生活中許多實際應用程序由各種網絡組成。在這些網絡的運行過程中,它們可能會受到無法預測或無法控制的破壞性事件的干擾。這些破壞性事件包括但不限於人為錯誤,自然災害,或是惡意攻擊。就網絡體系結構而言,破壞性事件造成的損失主要是組件損壞或組件之間的連接路徑故障。當運行中的網絡遭到破壞時,往往會造成自然的生態或經濟損失。衡量網絡抵禦破壞和恢復能力的績效指標正是網絡的彈性。因此,系統性且有效地測量網絡彈性是一個值得討論的話題。基於對網絡可靠性的評估方法,即二進制加法樹算法(binary addition tree algorithm, BAT),提出了一種基於二進制加法樹的彈性評估(binary add

ition tree-based resilience assessment, BAT-RA)和時間相關的BAT-RA(time-related BAT-RA, t-BAT-RA),以分析非循環二進制狀態網絡的彈性。本文還提供了通過擬議的BAT-RA和 t-BAT-RA分析的野火無線檢測傳感器網絡的網絡彈性的案例研究。BAT-RA考慮了破壞性事件的隨機性,並基於最佳可行技術全面列出了所有可能的破壞性情景和相應的整體修復策略,然後計算了網絡的靜態彈性。t-BAT-RA 比 BAT-RA 進一步考慮了動態恢復策略,並專注於更容易發生的破壞性事件、更多的參數和決策變量、仍然包括保護和恢復策略的成本、

三階段策略制定(即保護,攻擊和恢復),以及用於量化網絡彈性的網絡可靠性恢復程度的新性能指標。此外,對於選擇具有成本約束(即恢復受損網絡的預算)和網絡彈性要求的恢復策略的決策者,建議的BAT-RA可以以不同的成本獲得網絡彈性,從而幫助決策者確定恢復受損網絡的預算,並獲得所需的網絡彈性性能。

以RANS紊流模型探討不同高寬比之地面單斜太陽能棚架平均風壓特性

為了解決Civil Engineering ra的問題,作者蔡宇勛 這樣論述:

太陽能發電為目前國際上積極發展之重要綠色能源之一,各地設置於建築物屋頂或地面的太陽光電系統日漸增多。目前常見的太陽能光電系統大致分成五類,分別為斜屋頂平貼型、屋頂距置型、地面距置型、地面單斜式棚架型與平屋頂單斜式棚架型。依據國內相關規範,當地面單斜式棚架型之高寬比(棚架的屋頂平均高度除以屋頂弦長水平投影)介於0.25到1之間時,風壓係數為定值。而在此參數範圍外,規範未規定其風壓係數。因此,本研究針對地面單斜式太陽能棚架,使用計算流體力學方法模擬其平均受力特性;紊流模型採用穩態SST k-ω 模型,來流之上游假設為開闊地況;將依據風洞實驗結果來驗證模擬的準確性。再分別模擬棚架屋頂傾角10度、3

0度,以及不同高寬比之棚架,比較其平均風壓係數的差異性,作為地面單斜式棚架型耐風設計上之參考。本研究發現網格加密後,屋頂大部分平均風壓係數差異不大,但在屋頂邊緣會產生較平滑且合理的趨勢。當屋頂傾角較大時,CFD結果與風洞實驗結果較為接近,判斷是由於此時屋頂後方產生較大尺度雙渦流,SST k-ω 模型會有較準確之結果,同時風洞實驗屋頂下柱子的影響不大。當高寬比較小時,高寬比的變化會造成屋頂最大正風壓係數及最大負風壓係數較明顯的變化。
