【摘要】：本文以A工程公司的管道三維設(shè)計(jì)為實(shí)際背景,介紹了基于約束理論TOC的關(guān)鍵鏈法在管道三維設(shè)計(jì)進(jìn)度管理中的應(yīng)用。本文的目標(biāo)是期望能有效運(yùn)用“兩鍵”法之長(zhǎng),對(duì)原有的三維設(shè)計(jì)時(shí)間估算采用關(guān)鍵路徑法CPM,確定關(guān)鍵路徑;同時(shí)采用關(guān)鍵鏈法CCM,減少安全時(shí)間,縮短設(shè)計(jì)周期。作者首先介紹了油脂工程的傳統(tǒng)進(jìn)度管理方法中所涉及的基本概念,分析了管道三維設(shè)計(jì)運(yùn)用關(guān)鍵路徑法CPM的現(xiàn)狀,提出了關(guān)鍵路徑法在遇到資源約束或突發(fā)情況時(shí)有局限而不滿足進(jìn)度管理的實(shí)際情況。其次,提出了基于約束理論TOC的關(guān)鍵鏈法CCM可以填補(bǔ)關(guān)鍵路徑法CPM在進(jìn)度管理方面的缺陷,運(yùn)用關(guān)鍵鏈法CCM和緩沖區(qū)的概念,來克服資源約束或突發(fā)情況的影響,對(duì)推進(jìn)管道三維設(shè)計(jì)進(jìn)度管理提供了有效的途徑。最后,此建立基于關(guān)鍵鏈法的管道三維設(shè)計(jì)進(jìn)度管理模型,通過時(shí)間估計(jì)因素分析來消除安全時(shí)間以及運(yùn)用根方差法計(jì)算緩沖區(qū)的大小,目的是使管道三維設(shè)計(jì)過程中的資源約束或突發(fā)情況給進(jìn)度管理帶來的影響降到最小。本文通過關(guān)鍵鏈法和關(guān)鍵路徑法在管道三維設(shè)計(jì)進(jìn)度管理中的應(yīng)用對(duì)比,得出關(guān)鍵鏈法不論是發(fā)生資源約束或突發(fā)情況時(shí),都不需要重新調(diào)整進(jìn)度。關(guān)鍵路徑的時(shí)間從192天改進(jìn)為159天。從管道三維設(shè)計(jì)的完工時(shí)間看,應(yīng)用關(guān)鍵鏈法三維設(shè)計(jì)不但進(jìn)度沒有延誤,而且還提前了31天完成。本文的研究結(jié)果若能在大型石化項(xiàng)目的管道三維設(shè)計(jì)進(jìn)度管理上應(yīng)用,乃至覆蓋整個(gè)項(xiàng)目階段或項(xiàng)目全過程上推廣應(yīng)用,會(huì)給工程公司及業(yè)主帶來不可低估的經(jīng)濟(jì)效益。
[Abstract]:In this paper, the application of key chain method based on constraint theory TOC in pipeline 3D design schedule management is introduced based on A engineering company's 3D pipeline design. The aim of this paper is to effectively use the "two-key" method to estimate the 3D design time by using the critical path method (CPM) to determine the critical path, and to use the key chain method (CCM) to reduce the safety time and shorten the design period. Firstly, the author introduces the basic concepts involved in the traditional schedule management method of oil and fat engineering, and analyzes the present situation of using the critical path method (CPM) in the 3D pipeline design. In this paper, the critical path method is proposed to meet the constraints of resource constraints or unexpected situations, but not to meet the actual situation of schedule management. Secondly, the critical chain method (CCM) based on constraint theory (TOC) can fill the defects of critical path method (CPM) in schedule management. The concepts of critical chain method (CCM) and buffer zone are used to overcome the influence of resource constraints or unexpected situations. It provides an effective way for the management of the three-dimensional design schedule of the propulsion pipeline. Finally, a pipeline 3D design schedule management model based on critical chain method is established. The safety time is eliminated by time estimation factor analysis and the size of buffer zone is calculated by root variance method. The aim is to minimize the impact of resource constraints or unexpected situations on schedule management in the process of 3D pipeline design. By comparing the application of critical chain method and critical path method in pipeline 3D design schedule management, it is concluded that the critical chain method does not need to readjust progress when resource constraints or emergencies occur. Critical path time improved from 192 days to 159 days. According to the completion time of 3D pipeline design, the application of key chain method is not only without delay, but also 31 days ahead of schedule. If the research results of this paper can be applied to the management of 3D pipeline design schedule of large petrochemical projects, and even to the whole project stage or the whole process of the project, it will bring the engineering company and the owner economic benefits that can not be underestimated.
