【摘要】：Goldratt(1997)最早提出了關(guān)鍵鏈項目管理方法。關(guān)鍵鏈理論的提出,為受限于資源的項目進度管理提供了一種解決思路,不僅極大地縮短了工期,同時可以在項目進行過程中實現(xiàn)動態(tài)管理。因此,眾多學者在給予關(guān)鍵鏈理論高度評價的同時,不斷進行研究探索、改進和優(yōu)化,相繼提出了許多關(guān)鍵鏈項目進度管理方法,也有很多基于關(guān)鍵鏈理論的應用研究。目前,基于關(guān)鍵鏈理論的項目進度管理應用研究已涉及電力工程、科研項目、軟件開發(fā)、工業(yè)工程等領(lǐng)域,并取得了一定的成效。數(shù)字化、自動化和智能化是當今世界裝備制造業(yè)發(fā)展的趨勢,裝備制造業(yè)企業(yè)通過技術(shù)改造實現(xiàn)數(shù)字化生產(chǎn)和管理是適應發(fā)展趨勢、提高經(jīng)濟效益、增強核心競爭力的必由之路。然而,數(shù)字化技術(shù)改造項目具有投資大、周期長、技術(shù)難度大、制約因素多、不確定系數(shù)高等特點,要求必須采取有效的項目進度管理方法實施管理,確保項目順利完工。關(guān)鍵鏈項目進度管理考慮了項目任務(wù)間的邏輯關(guān)系和資源制約因素,通過設(shè)置緩沖區(qū)來消除不確定性因素的影響,并通過對緩沖區(qū)的監(jiān)控實現(xiàn)對項目進度的實時控制。本文提出了關(guān)鍵鏈項目進度管理的新思路和緩沖區(qū)設(shè)置、監(jiān)控的新方法,豐富了關(guān)鍵鏈理論,拓寬了關(guān)鍵鏈理論的應用領(lǐng)域。同時,通過基于關(guān)鍵鏈的數(shù)字化技術(shù)改造項目進度管理模型,為企業(yè)數(shù)字化技術(shù)改造項目進度管理提供了一種科學有效的進度管理模式,為企業(yè)避免進度管理失控帶來的工期延誤、管理成本增加、經(jīng)濟效益受損等問題提供了有效的解決途徑,對今后企業(yè)數(shù)字化技術(shù)改造項目進度管理具有借鑒和示范作用。本文首先闡述了研究背景、研究內(nèi)容、研究方法、技術(shù)路線、研究的意義及創(chuàng)新之處。其次,本文對項目進度管理、約束理論和關(guān)鍵鏈理論進行了文獻綜述的研究。然后介紹了T公司數(shù)字化技術(shù)改造項目概況,分析了T公司數(shù)字化技術(shù)改造項目進度管理的現(xiàn)狀,指出了項目存在的問題。本文重點通過構(gòu)建基于關(guān)鍵鏈的進度管理模型對T公司數(shù)字化技術(shù)改造項目進度管理進行應用,主要包括關(guān)鍵鏈項目進度計劃、緩沖區(qū)設(shè)置和關(guān)鍵鏈項目進度控制三個部分。在關(guān)鍵鏈緩沖區(qū)設(shè)置時,本文在基于鏈路特征的基礎(chǔ)上,提出了將基于項目特征的不確定性指標納入綜合評價指標體系,利用熵權(quán)法和TOPSIS法計算不確定系數(shù),再利用根方差法計算緩沖區(qū)的大小。在關(guān)鍵鏈項目進度控制方面,本文提出了斜率法預警區(qū)域劃分和監(jiān)控觸發(fā)點設(shè)置方法,即設(shè)置兩條斜率基于工序不確定性系數(shù)的線段將預警區(qū)域劃分為三部分,通過某時刻項目進度對應的斜率大小判斷所屬的預警區(qū)域。然后提出在緩沖量動態(tài)分配的基礎(chǔ)上,對緩沖區(qū)進行動態(tài)緩沖滾動監(jiān)控。最后,本文對基于關(guān)鍵鏈的T公司數(shù)字化技術(shù)改造項目進度管理的優(yōu)化效果進行了分析,得出主要研究成果和項目管理啟示,指出研究的不足之處以及未來的研究方向。
[Abstract]:Goldratt (1997) proposed the first critical chain project management method. Put forward the critical chain theory, provides a new method for project schedule management of limited resources, not only greatly shorten the construction period, and can realize the dynamic management process in the project. Therefore, many scholars give highly critical chain theory at the same time, the ongoing research and exploration, improvement and optimization, have put forward many critical chain project schedule management method, there are a lot of application research based on critical chain theory. At present, the key chain project management theory research has been applied in power engineering, based on the scientific research project, software development, industrial engineering and other fields, and certain achievements have been made. The digital, intelligent and automation is the development of the world manufacturing industry trend, equipment manufacturing enterprises to realize digital tube production and through technical transformation Is to adapt to the development trend, improve economic efficiency, enhance the core competitiveness of the only way which must be passed. However, the digital technology renovation project with large investment, long cycle, high technical difficulty, many restricting factors, uncertain characteristics of higher demand coefficient, we must take effective management of project progress management method, ensure that the project was successfully completed. The key chain project schedule management is considered the logical relationship and resource constraints project between the tasks, by setting the buffer to eliminate the influence of uncertain factors, and realize the real-time control of the project progress by monitoring the buffer. This paper proposes a new idea and buffer critical chain project management, a new method for monitoring. Enrich the critical chain theory, broaden the application field of critical chain theory. At the same time, through the model of digital technology transformation project schedule management based on critical chain, as the number of enterprises 瀛楀寲鎶，
