【摘要】：當(dāng)今市場(chǎng)經(jīng)濟(jì)條件下的競(jìng)爭(zhēng)日益激烈，現(xiàn)代項(xiàng)目管理日趨復(fù)雜，工程項(xiàng)目進(jìn)度管理作為項(xiàng)目管理中的重要組成部分有著很重要的現(xiàn)實(shí)意義。隨著信息技術(shù)發(fā)展以及市場(chǎng)結(jié)構(gòu)的變化，大多數(shù)企業(yè)都處于多項(xiàng)目環(huán)境中，多項(xiàng)目管理成為一種趨勢(shì)。 針對(duì)工程多項(xiàng)目復(fù)雜度大和計(jì)劃執(zhí)行過(guò)程中不確定因素多的特點(diǎn)，傳統(tǒng)的單項(xiàng)目關(guān)鍵鏈管理方法已不再適用，將關(guān)鍵鏈項(xiàng)目管理引入到多項(xiàng)目動(dòng)態(tài)管理中，對(duì)其展開(kāi)深入研究。首先，在識(shí)別單項(xiàng)目關(guān)鍵鏈的基礎(chǔ)上，提出一種基于CARVER矩陣的多項(xiàng)目綜合優(yōu)先級(jí)系數(shù)的計(jì)算方法，，來(lái)實(shí)現(xiàn)資源約束的多項(xiàng)目調(diào)度問(wèn)題；其次為解決項(xiàng)目管理中諸多不確定性問(wèn)題，提出關(guān)鍵鏈緩沖區(qū)尺寸設(shè)置新方法。該方法從項(xiàng)目屬性角度出發(fā)，以PERT三點(diǎn)估計(jì)中的最樂(lè)觀時(shí)間作為工序持續(xù)時(shí)間，在綜合考慮工序關(guān)鍵性、工序復(fù)雜度、位置權(quán)重、風(fēng)險(xiǎn)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(píng)價(jià)法，計(jì)算各工序受多重不確定性因素影響的綜合浮動(dòng)影響因子，并將影響因子與安全時(shí)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(shè)計(jì)更加科學(xué)，與實(shí)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(diǎn)，同時(shí)考慮工作完成量與緩沖消耗量，并通過(guò)在易延誤的工序后加設(shè)監(jiān)控點(diǎn)來(lái)實(shí)現(xiàn)緩沖區(qū)消耗的動(dòng)態(tài)監(jiān)控，使管理決策更加及時(shí)、準(zhǔn)確。最后通過(guò)實(shí)例分析表明，本文提出的多項(xiàng)目關(guān)鍵鏈進(jìn)度計(jì)劃與動(dòng)態(tài)管理模型縮短了工期，保證了工程項(xiàng)目按期完工，使工程多項(xiàng)目進(jìn)度計(jì)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(xiàng)目中的應(yīng)用提供一定參考價(jià)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uncertain factors in the process of project execution, the traditional method of single project key chain management is no longer applicable, so the key chain project management is introduced into the multi-project dynamic management, and the key chain project management is deeply studied.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.
