摘要

在選擇高聚光型太陽光(HCPV)發電廠場址時，專家會依照性質及用途的不同，而做出不同的決策，以提高選址的準確性及可靠性。目前選擇場址的演算法有分析層級法、地理資訊系統、標籤演算法等多種，也可以結合不同的演算法來彌補各自的缺點。在選擇高聚光型太陽光發電廠的建置場址時，須對安裝地點之人為或非人為相關等因素進行通盤性考量，評估出最適合建置高聚光型太陽光發電廠場址。而本研究提出一個以「分析層級演算法（AHP）及貝氏信心網路演算法（BBN）為基礎之輔助選址模式」，找出最適合建置高聚光型太陽光發電廠場址的決策建議。

虛擬實境技術的應用，使得燴炙人口的電影阿凡達(Avatar)自2010年元月至目前為止，保持電影票房冠軍記錄。阿凡達是一個電腦技術常見術語，指的是在虛擬實境中以抽象化、且完美地呈現出人形。虛擬實境的技術不只是在娛樂業大放異彩，在工程設計方面也逐漸取代了2D、3D設計方式。本研究是利用虛擬實境技術，進行互動式的高聚光型太陽光發電廠的場景及影像動態模擬系統的開發；即利用太陽移動軌跡及太陽光追蹤系統的運作、程式設計、影像處理、3D物件繪圖等技術，達到即時互動、多樣化設計功能。本研究提出模擬系統，擁有高度的互動性與參與感開發平台，讓設計人員以不同的時間、地點或條件觀看模擬的建置成果，協助設計人員找出最適合的建置樣式，提供最有效率的設計流程與方法，減少建置時不必要的錯誤，並縮短設計時間、提高建置效率與減少金錢的浪費。

To make a precise and reliable decision for choosing installation site for a high concentration photovoltaic (HCPV) power plant, experts make their decision based on the plant’s characteristics and applications. Various algorithms are used, such as Analytical Hierarchy Process (AHP), Geographic Information Systems (GIS), Label setting algorithm, and etc. Moreover, several different algorithms can be used together to compensate the defects of the others. The in-site installation factors, either man-made or natural, should be analyzed first before decision for site location. This research employs the AHP and Bayesian Belief Network (BBN) for strategic planning of choosing the appropriate installation site of a HCPV power plant.

Virtual Reality (VR) technology manipulated by Avatar, which is a computer terminology often used to abstractly and perfectly display the animated human shape, has topped the global box office record since January 2010. VR becomes the spotlight not only in the entertainment, but also in engineering design, where it gradually replaces 2D and 3D design work. This research used VR technology to develop an interactive scene of a High Concentration Photovoltaic power plant for establishing. This work constructed a dynamic image simulation system using VR. The techniques use by the system include the solar trajectory and trackers, programming, image processing, 3D object tools, etc. Moreover, the simulation system developed by the research supports user interaction and participation; it allows designers to view the construction results based on different time, place, and conditions. It helps designers optimize the design, avoid unnecessary faults, shorten design schedule, and enhance establishment efficiency, and reduce design cost.
