工程流程與計畫管理的好壞是一個工程成功與否的關鍵指標，一般來說，工程在執行過程中常會遇到四種衝突包括工項與工項的順序、工項與工人的數量和合適度、工項執行區域間的壅擠和工項與資源分配等衝突。關於個別面向，考慮上述的一個或兩個衝突的研究已經有不少，然而一個完整的方法或框架來偵測四個常常在工程流程中出現的衝突是不常見的。因此，此研究希望利用建築資訊模型(BIM)、動態網絡分析(DNA)和圖形資料庫(GraphDB)來探究四個衝突發生的來源與衝突能夠在整個專案裡面產生的影響程度。此外，此研究會將成果測試於一個水泥預熱鋼構塔的重建工程案子，從此案子的資料中檢測出四個前述的衝突。由於工程計畫本身就是動態且有多種形態的資料，動態網路分析支援多種形態的節點與鏈結的特性就相對適合在此研究中使用。最後的分析結果，除了多個衝突被檢測之外，每個衝突的影響力程度也被計算出來，用於幫助專案經理了解衝突的緊急程度與處理的優先順序。藉由偵測衝突之後的解決衝突，專案的流程也能因此更為順利。

Construction workflow management is one of the most crucial keys to the success of any construction project. Normally, most construction projects would be facing with several construction conflicts which include (1) activity to activity (2) activity to labour (3) activity to location (4) activity to resource conflicts. There is already plenty of research concentrating on one or two aforementioned conflicts. However, only a few holistic methods or frameworks deal with all of those four conflicts which play a great portion in the cause of construction delay. This research aims to integrate Building Information Modelling (BIM), Dynamic Network Analysis (DNA) and graph database (GraphDB) to have a deeper insight into how these four conflicts formed and how they can influence on the whole project. A case study for a cement preheater tower renovation project is also presented. To apply the proposed method, four different scenarios are suggested for the aforementioned conflicts respectively. Taking advantage of the multi-node and multi-link characteristics of the DNA, multiple factors can be taken into consideration in the analysis which is similar to the situation while planning the construction workflow. From the result of the case study, several conflicts are identified and the influence level of conflicts are calculated for the manager to prioritise the adjustments made for resolving them. By eliminating four kinds of detected conflicts through the proposed method, the construction workflow can be improved.
