營建工程之作業程序，因受許多天候、地質狀況、機械故障等外在因素影響，隱含了高度的不確定性，而電腦模擬則能依循營建作業的特性，提供較適當之詮譯，且系統化分析作業流程，對整體作業產能有莫大幫助，亦可提供決策者判斷的客觀依據。 但現今大多數營建作業模擬系統遭遇兩大問題，一為模擬元件在營建作業問題描述之細緻度不足，過度簡化施作模型，造成未能將諸多現實條件納入考量，失去模擬真確反應現實作業流程施作情形之意義；二為使用者學習障礙，簡易系統利用『資源限制』反應施工作業上各類管制及問題發生，也因而產生大量『虛擬資源符號』，徒增建模圖形複雜度，且無法讓使用者了解其模型的邏輯及涵意。再者，少數功能強大的模擬系統，雖具備多樣條件之擴充性，但卻必須透過使用者輸入專屬模擬系統程式碼，甚至需自撰各項控制條件等問題。 因此，本研究針對目前營建作業之現況及需求，研擬便捷系統邏輯控制元件，並撰寫一雛形系統為其驗證，旨在讓使用者能適切應用『邏輯控制』元件，反應作業流程複雜的影響因子，解決複雜作業流程以及資源、人力配置問題，以期能有效管理營建作業流程，進而掌控其對工期成本影響，提昇整個工程的生產及執行效率。 Computer simulation is a valuable management tool which is well suited to the study of resource driven construction processes. It gives the analyst an insight into resource interaction and assists in identifying which factors in a problem domain are important. Simulation allows the modeler to experiment with and evaluate different scenarios. Normally, such experimentation and study would be too costly to be carried out in the real world. Interests have been generated since the introduction of CYCLONE methodology by Halpin in 1973, and been increasing with the development of many Windows-based construction simulation systems such as the COOPS, the DISCO, the Stroboscope, the SimCon, the Simphony. Numerous studies have been conducted to analyze the variety of construction operations including earth moving, pavement, tunneling, segmental construction of an elevated structure, and concrete placement in a high-rise building. The cyclic as well as the complex and dynamic aspects of construction operations make computer simulation a promising technique for the engineering analysis. Nevertheless, accessibility and usability of computer simulation techniques at the practitioner level create a barrier for its application. The practitioners who are conversant with construction operations frequently may see the use of simulation as "too difficult." Efforts need to be devoted to improving existing simulation systems, particularly the modeling elements, to facilitate their use in construction. This research is to study the various sets of modeling elements employed in the existing construction simulation systems, and to develop a new set of modeling elements which is simple and easy to use, and can meet the basic need for the planning and analysis of most construction operations. With the new set of modeling element, the accessibility of construction simulation can be enhanced.
