商用不動產市場開發模式之研究-以機場捷運A8車站為例 / Development Model Study on Commercial Real Estate Marketing - Airport MRT A8 Station of Structure Building Case Study李俊興, Li,chun hsing Unknown Date (has links)
本文主要在探討與捷運共構商用不動產市場開發模式之研究,期能參考國外經驗及以市場調查與潛在業者訪談方式,建立商用不動產之市場分析模式,作為開發者投資開發時之產品規劃依據,並評估以開發者之企業文化及潛在業者之經營意願,建議全案之營運或銷售模式,及進行開發效益分析與比較。
經以機場捷運A8車站為例進行研究,獲致結論主要為:捷運共構之商用不動產乃政府衡量車站用地以徵收方式取得困難,遂以鼓勵民間(地主及投資開發者)投資、參與公共建設方式,由政府與民間共享開發效益,達到三贏局面之最佳開發模式,由財務及其他各方面分析效益得知,政府除可免去取得私有土地紛爭或時程延宕外,亦可透過共同開發,挹注重大交通建設經費,民間亦可經由參與公共建設共享獎勵及開發效益,獲取高於土地被徵收時之利益,為一值得效法與推廣之開發模式。
惟開發者應在投資開發前,審慎評估個案之市場定位及投資效益,以作為規劃設計及將來營運模式之參考,避免規劃錯誤造成將來營運或產銷之效益不彰,影響投資報酬,並可作為前期招商之依據,因此建立可靠的商用不動產市場分析方式甚為重要。本文主要重點在於以個案分析進行商用不動產市場開發模式之研究,以作為後續開發相關案例之參考。 / This article is to explore the MRT structure of the commercial real estate’s market model of development. With drawing on foreign experience, the market research and interviews with potential operators, we can establish the commercial real estate market analysis model, as developer’s product planning principles when develop. And according to the corporate culture and potential industry management, it will be recommended to the case of operations or sales model, and to develop effective analysis and comparison.
Taking the co-structure building of A8 MRT station to the airport as a case study, to achieve the main conclusions are: To avoid the difficulities of acquiring private land, the government submits to encourage private investment (landlord and investment developers) to participate in public construction, share benefit to both the government and private. The MRT structure of commercial real estate is the best model of development to have a win-win situation. From financial and other aspects of effection, the government could dismiss the disputes of acquiring private land and avoiding the time-delay of engineering development. By co-structure of MRT and the commercial real estate building, the government could inject major transportation infrastructure funding, people can also enable the sharing through participation in public construction and development of effective incentive to get higher than the interest of the land acquired. Thus it is resumed a worthy example to follow and a promotion of the development model.
However, developers should evaluate assessment of the case of market position and investment results carefully in investment before development, and be a reference business model for future planning and design, so as not to cause an affected or inefficient investment returns of future operation and marketing sales because of planning errors, and also can be used as a basis for merchants. So how to set up a commercial real estate market analysis methods is important. This article focuses on commercial real estate market to establish a development model, as a reference for follow-up development of related cases.

Novel Analytical Hydrodynamic Modeling for Evaluating and Optimizing Alluvial Recharge: Principles, Model Approaches and Their Application for Water Resources Assessment in an Arid RegionPhilipp, Andy 17 July 2013 (has links)
This thesis presents a novel analytical solution strategy for the zero-inertia (ZI) equations of free surface flow. These equations are utilized herein for routing flood flow in open channels and for simulating excess rainfall runoff on overland planes. The novel solution approach is shown to be both accurate and robust, especially under the complicated and intricate conditions of infiltrating flow on initially dry river beds or soils, e.g., as present in arid and semiarid areas. This is underlain by comparing modeling results of the novel analytical procedure with those of validated numerical solutions. Furthermore, it is shown that the analytical ZI model can deliver a process-oriented portrayal of runoff concentration in the flood-generating parts of the catchment.
Subsequently, the novel analytical ZI model is applied for a real-world water management problem in the Sultanate of Oman, Arabian Peninsula. Within an integrated flash flood routing model—which is also presented in this thesis—the novel analytical routing approach helps in accurately matching the dynamics of advancing and infiltrating ephemeral river flow, established as a consequence of release from a groundwater recharge dam. The integrated modeling system houses the aforementioned analytical downstream model and tailor-made, state-of-the-art modeling components to portray the upstream flow processes, dam operation (including evaporation), and spillway release flow. The proposed modeling system can aid in rendering a realistic image of transient transmission losses and dependent flow dynamics. This is of extremely high importance for water resources assessment, as well as for optimizing recharge dam operation strategies in order to maximize downstream transmission losses and, thus, groundwater recharge.:List of Figures

B.3 Integrated Modeling System for Flash Flood Routing in Ephemeral Rivers / Diese Dissertation präsentiert einen neuartigen analytischen Lösungsansatz für das beschleunigungsfreie Wellenmodell (bzw. „Zero-Inertia-Modell“, „ZI-Modell“, oder „diffusives Wellenmodell“). Im Rahmen der Arbeit wird das hergeleitete hydrodynamische Modell sowohl zur Simulation von Freispiegelabflüssen in nichtprismatischen und durchlässigen Gerinnen, als auch für die Beschreibung von auf der Landoberfläche abfließendem Infiltrationsüberschuss eingesetzt. Es wird gezeigt, dass der neuartige analytische Ansatz — im Hinblick auf Massenerhaltung und die exakte Abbildung der Abflussdynamik — akkurate Ergebnisse liefert und gleichzeitig unter komplexen und verwickelten Prozessbedingungen anwendbar ist. So belegt eine vergleichende Analyse mit validierten numerischen Lösungsansätzen die Robustheit des analytischen ZI-Modells. Insbesondere die im Sinne der numerischen Mathematik stabile und genaue Modellierung der gekoppelten Abfluss- und Infiltrationsvorgänge in anfänglich trockenen Gerinnen ist dabei ein Novum. Weiterhin wird die Eignung und Anwendbarkeit des neuartigen Modellansatzes zur Beschreibung der Abflusskonzentrationsprozesse gezeigt.
Der neuartige Lösungsansatz wird im Folgenden für ein reales Wassermanagementproblem im Sultanat Oman, Arabische Halbinsel eingesetzt. Als Bestandteil eines integrierten Modellsystems, welches ebenfalls im Rahmen der Dissertation vorgestellt wird, dient das analytische ZI-Modell zur Simulation von infiltrierendem Wadiabfluss, welcher unterstrom von Grundwasseranreicherungsdämmen starke Verluste von Masse und Impuls erfährt. Zusammen mit maßgeschneiderten und dem Stand der Technik entsprechenden Komponenten für die Betriebssimulation des Anreicherungsdammes (inklusive Verdunstung von der freien Seefläche) sowie für die Abbildung der oberstromigen hydrodynamischen Prozesse (ebenfalls inklusive Infiltration) wird der neuartige analytische Ansatz in einem Modellsystem zusammengefasst. Das Modellsystem ist in der Lage ein realistisches Bild der raumzeitlichen Dynamik des Abflusses sowie der Grundwasserneubildung aus infiltrierendem Wadiabfluss zu liefern. Damit stellt das Modellsystem ein wertvolles Werkzeug sowohl zur Wasserdargebotsermittlung, als auch für die Optimierung des Betriebes von Grundwasseranreicherungsdämmen dar.:List of Figures
