摘要:	1 電腦模擬技術是流程分析研究之有效工具，自從1973年Halpin 發展出第一套專屬於營建業之作業模擬系統後，已成功應用於各項營建作業流程之規劃與研究，如土方工程、橋樑工程、瀝青鋪面等方面。CYCLONE 運用了六個簡單符號（ NORMAL 、COMBI 、QUEUE 、 FUNCTION、COUNTER 、ARC ）有助於工程人員的學習及應用，之後發展之營建作業模擬系統都直接或間接地參考了CYCLONE 之模型符號，帶起了電腦模擬技術在營建作業規劃分析之研究與應用風潮。然而，也因為CYCLONE 簡易之元件符號，造成其於模擬功能上的限制，其中最大的限制為僅能設定相同屬性之資源於同一QUEUE 等待結點之中，例如在土方載運作業中，只能設定相同容量的卡車於同一QUEUE 結點中，使得當使用不同屬性的資源（如大卡車與小卡車）時，相同之作業循環必須依各種資源重複地描述於模型中，本研究擬結合現有營建作業模擬系統之優點，運用CYCLONE 六項簡單的模型建立符號及資源物件化之方式，發展一套新的模擬系統以解決現有營建作業模擬系統之限制。研究過程中將規劃整體系統之架構及雛形系統之實作與驗證，以作為日後發展之依據。 Computer simulation is a valuable management tool well suited to the study of resource driven processes. Interests in applying the computer simulation technique for the planning and analysis of construction operations have been growing since the introduction of CYCLONE methodology by Halpin in 1973. Numerous research studies on various construction operations such as tunneling, bridge construction, earthmoving, asphalt paving and so on can be found in literature. The CYCLONE’s six standard modeling elements (namely NORMAL, COMBI, QUEUE, CONSOLIDATION, COUNTER and ARC) is simple and easy for the field engineers to learn and provides a convenient tool for modeling and simulation analysis of construction operations. Many construction-specific simulation systems developed later on use the similar set of elements for their modeling. Nevertheless, CYCLONE’s simplicity on the other hand limits its functionality for simulation. One of its greatest restraints is that the resource to be initialized in one QUEUE has to be the same kind with the same attributes. For instance, in an earthmoving operation trucks initialized in a queue must be exact the same and can not have different loading capacity or performance parameters. As a result, when same kind of resources but with different attributes (e.g., large trucks and small trucks) have to be included in the system, same operating cycle must repeat for each resource with different attributes. It complicates the system model and results in the ineffectiveness of the simulation. This research takes advantages of the recent development in object-oriented design and aims at developing a new simulation system to enhance the simulation capability of CYCLONE. The idea is to preserve the simplicity of CYCLONE’s six modeling elements while at the same time enhance their capability for simulation using the object paradigm. An enhanced modeling scheme and a prototype simulation system to implement the new scheme will be developed and tested in this study. Literature review on the development of construction simulation systems as well as object-oriented design will be conducted.
