【摘要】：當今市場經(jīng)濟條件下的競爭日益激烈，現(xiàn)代項目管理日趨復雜，工程項目進度管理作為項目管理中的重要組成部分有著很重要的現(xiàn)實意義。隨著信息技術(shù)發(fā)展以及市場結(jié)構(gòu)的變化，大多數(shù)企業(yè)都處于多項目環(huán)境中，多項目管理成為一種趨勢。 針對工程多項目復雜度大和計劃執(zhí)行過程中不確定因素多的特點，傳統(tǒng)的單項目關(guān)鍵鏈管理方法已不再適用，將關(guān)鍵鏈項目管理引入到多項目動態(tài)管理中，對其展開深入研究。首先，在識別單項目關(guān)鍵鏈的基礎(chǔ)上，提出一種基于CARVER矩陣的多項目綜合優(yōu)先級系數(shù)的計算方法，，來實現(xiàn)資源約束的多項目調(diào)度問題；其次為解決項目管理中諸多不確定性問題，提出關(guān)鍵鏈緩沖區(qū)尺寸設置新方法。該方法從項目屬性角度出發(fā)，以PERT三點估計中的最樂觀時間作為工序持續(xù)時間，在綜合考慮工序關(guān)鍵性、工序復雜度、位置權(quán)重、風險彈性系數(shù)四種參數(shù)的基礎(chǔ)上，采用AHP-熵組合賦權(quán)的模糊綜合評價法，計算各工序受多重不確定性因素影響的綜合浮動影響因子，并將影響因子與安全時間裕量的乘積作為各工序的緩沖量，從而使緩沖區(qū)尺寸的設計更加科學，與實際結(jié)合也更加緊密；在緩沖區(qū)監(jiān)控中，為體現(xiàn)緩沖區(qū)加速消耗的特點，同時考慮工作完成量與緩沖消耗量，并通過在易延誤的工序后加設監(jiān)控點來實現(xiàn)緩沖區(qū)消耗的動態(tài)監(jiān)控，使管理決策更加及時、準確。最后通過實例分析表明，本文提出的多項目關(guān)鍵鏈進度計劃與動態(tài)管理模型縮短了工期，保證了工程項目按期完工，使工程多項目進度計劃具有較高的穩(wěn)定性、可行性和高效性，為該技術(shù)在工程多項目中的應用提供一定參考價值。
[Abstract]:Under the condition of market economy, the competition is becoming increasingly fierce, and the modern project management is becoming more and more complicated. As an important part of project management, project schedule management has very important practical significance. With the development of information technology and the change of market structure, most enterprises are in multi-project environment, multi-project management has become a trend. In view of the complexity of multi-project and the uncertain factors in the process of project execution, the traditional method of single project key chain management is no longer applicable, so the key chain project management is introduced into the multi-project dynamic management, and the key chain project management is deeply studied. Firstly, on the basis of identifying the key chain of single project, a multi-project comprehensive priority coefficient calculation method based on CARVER matrix is proposed to realize the multi-project scheduling problem with resource constraints. Secondly, in order to solve many uncertain problems in project management, a new method of setting the buffer size of key chain is proposed. From the point of view of project attributes, the most optimistic time in PERT three-point estimation is taken as the duration of the process, and four parameters, namely, the key process, the complexity of the process, the weight of position and the elastic coefficient of risk, are considered synthetically. The fuzzy comprehensive evaluation method based on AHP- entropy combination weight is used to calculate the comprehensive floating influence factors which are affected by many uncertain factors. The product of the influence factors and the safety time margin is taken as the buffer of each process. Therefore, the design of buffer size is more scientific, and the combination with practice is more close. In the buffer monitoring, in order to reflect the characteristics of the buffer accelerated consumption, the amount of work done and the buffer consumption are considered at the same time, and the dynamic monitoring of the buffer consumption is realized by adding the monitoring points after the easily delayed process. Make management decisions more timely and accurate. Finally, through the analysis of examples, it is shown that the multi-project key chain schedule and dynamic management model proposed in this paper can shorten the construction period, ensure the completion of the project on schedule, and make the multi-project schedule more stable. The feasibility and efficiency provide some reference value for the application of this technology in many projects.
