【摘要】：隨著經(jīng)濟(jì)的發(fā)展,現(xiàn)代項(xiàng)目的市場(chǎng)競(jìng)爭(zhēng)越來(lái)越激烈,項(xiàng)目的獨(dú)特性、復(fù)雜性和不確定性都越來(lái)越大,因而若要使項(xiàng)目團(tuán)隊(duì)更具有競(jìng)爭(zhēng)力,則需要項(xiàng)目管理能控制在更短的工期內(nèi)以更低的成本完成更高質(zhì)量的項(xiàng)目要求。其中,“更短的工期”就要求項(xiàng)目管理者做好項(xiàng)目的進(jìn)度控制,而進(jìn)度控制作為項(xiàng)目控制大三大要素之一,與成本和質(zhì)量也是息息相關(guān)的。因而,制定一個(gè)全面的進(jìn)度計(jì)劃并對(duì)其進(jìn)行進(jìn)度監(jiān)控,是實(shí)現(xiàn)項(xiàng)目總盈利的關(guān)鍵環(huán)節(jié)。關(guān)鍵鏈項(xiàng)目進(jìn)度管理是一種將資源緊缺程度和工序先后順序放在同等重要的位置考慮的進(jìn)度管理方法,并且能考慮到人為因素的影響,吸收更多的項(xiàng)目不確定性。因其諸多方面的優(yōu)越性,關(guān)鍵鏈管理法近年來(lái)受到企業(yè)和學(xué)術(shù)界的廣泛關(guān)注,并得以成功應(yīng)用在諸多實(shí)踐中。本研究主要運(yùn)用改進(jìn)的灰色關(guān)鍵鏈的方法進(jìn)行風(fēng)險(xiǎn)影響下的項(xiàng)目進(jìn)度管理,解決在項(xiàng)目執(zhí)行過(guò)程中產(chǎn)生的不確定性給項(xiàng)目實(shí)施帶來(lái)的困難等問(wèn)題,并對(duì)關(guān)鍵鏈進(jìn)度計(jì)劃中的關(guān)鍵鏈識(shí)別與緩沖設(shè)立,以及進(jìn)度控制過(guò)程中的緩沖監(jiān)控管理進(jìn)行了進(jìn)一步的研究：首先,本文在識(shí)別確認(rèn)關(guān)鍵鏈階段,將客觀的灰色關(guān)聯(lián)度分析法與偏向主觀的層次分析法相結(jié)合,使得灰色關(guān)鍵鏈在確定中取得更切合實(shí)際的指標(biāo)權(quán)重與理想對(duì)象；其次,針對(duì)現(xiàn)有關(guān)鍵鏈識(shí)別與緩沖區(qū)設(shè)立將各個(gè)工序考慮成相互獨(dú)立無(wú)影響的弊端,提出了風(fēng)險(xiǎn)影響下的工序關(guān)聯(lián)度這一指標(biāo),當(dāng)項(xiàng)目遭遇到某種風(fēng)險(xiǎn),考慮到受此風(fēng)險(xiǎn)影響的工序因其具有關(guān)聯(lián)性將會(huì)產(chǎn)生連鎖反應(yīng),使得緩沖區(qū)能夠吸收更多的項(xiàng)目不確定性；最后,針對(duì)普遍使用的緩沖監(jiān)控方法不能及時(shí)反映項(xiàng)目不確定性逐漸減小這一問(wèn)題,提出了動(dòng)態(tài)的緩沖監(jiān)控模型。在動(dòng)態(tài)緩沖監(jiān)控過(guò)程中,管理者將動(dòng)態(tài)地調(diào)整觸發(fā)點(diǎn),隨著項(xiàng)目進(jìn)展實(shí)時(shí)更新各個(gè)鏈路的緩沖大小,使得這個(gè)動(dòng)態(tài)模型下的緩沖監(jiān)控能發(fā)出更準(zhǔn)確的、更符合實(shí)際情況的預(yù)警信號(hào)。并通過(guò)實(shí)例對(duì)比及仿真模擬證實(shí)本文所提關(guān)鍵鏈進(jìn)度控制方法的優(yōu)越性。
[Abstract]:With the development of economy, the market competition of modern project is becoming more and more fierce, the uniqueness, complexity and uncertainty of the project are increasing, so if the project team is to be more competitive, Project management is required to achieve higher quality project requirements at lower cost in a shorter time frame. Among them, "shorter duration" requires project managers to do a good job of project schedule control. As one of the three major elements of project control, schedule control is closely related to cost and quality. Therefore, it is the key to realize the total profit of the project to make a comprehensive progress plan and monitor its progress. The key chain project schedule management is a kind of schedule management method, which considers the degree of resource shortage and the sequence of working procedure in the same important position, and can take into account the influence of human factors and absorb more project uncertainty. Because of its advantages in many aspects, the key chain management method has been widely concerned by enterprises and academia in recent years, and has been successfully applied in many practices. This research mainly uses the improved grey key chain method to manage the project schedule under the influence of risk, and solves the difficulty of project implementation caused by the uncertainty in the process of project implementation. Furthermore, the key chain identification and buffer establishment in the key chain schedule and the buffer monitoring management in the progress control process are further studied. Firstly, this paper is in the phase of identifying and confirming the critical chain. Combining the objective grey correlation analysis method with the subjective analytic hierarchy process makes the grey key chain obtain more realistic index weight and ideal object in the determination; Secondly, aiming at the disadvantage of existing key chain identification and buffer zone setting, considering each process as independent and independent, this paper puts forward the index of process correlation degree under the influence of risk, when the project encounters some kind of risk, Considering that the processes affected by this risk will have a chain reaction because of their relevance, the buffer zone will be able to absorb more project uncertainty; Finally, a dynamic buffer monitoring model is proposed to solve the problem that the commonly used buffer monitoring method can not reflect the uncertainty of the project gradually. In the process of dynamic buffer monitoring, the manager will dynamically adjust the trigger point and update the buffer size of each link in real time as the project progresses, so that the buffer monitoring under this dynamic model can be issued more accurately. A more realistic warning signal. Through the comparison of examples and simulation, the superiority of the key chain schedule control method proposed in this paper is confirmed.
