摘要

污水下水道新建工程為典型之重複性工程。在實務上此種工程通常使用一般施工網圖進行排程，但一般之施工網圖並不易表達重複性工程之軟邏輯(soft logic)，且此種工程在施工執行過程中常常遭受無法預知因素(例如：路證核准之延遲、民眾陳情、天氣不佳或地下障礙物等)之干擾，致使施工經常出現脫序作業現象，造成施工網圖的失真與現況不符，而此網圖必須仰賴人工修正，十分耗時費力。因此，本研究以風險控管角度，檢核工程之工作分解結構，提出簡化排程的流程與策略。此策略藉由簡化重複性工程排程組合變異，以分析關鍵工項的資源使用來建立軟邏輯作業關係和定義施工之工作面，並且在分析出專案排程策略後，根據關鍵工項的資源與優先順序產生施工排程。如此可以有效地考慮施工排程之軟邏輯，並提高排程的效率。

The pipe-jack projects are repetitive projects and may often be delayed by some unpredictable factors, such as underground barriers, bad weather condition, etc., while they are under construction. Usually the project network diagrams are used in these projects for their scheduling. However, the project network diagrams cannot easily handle the soft logics in repetitive projects. Also, the editing of them for synchronization with project changes is very time-consuming and labor-intensive. Therefore, this research proposes a scheduling strategy that identifies the key work items in WBS (Work Breakdown Structure) from the perspective of risk control, analyzes the resources associated with the key work items to define the soft logics and concurrent working processes, and then produces the scheduling results based on the resources and priority of the key work items. The proposed scheduling strategy can effectively account for the soft logics and allow for efficient scheduling for pipe-jack projects.
