【摘要】：科技園區(qū)項(xiàng)目包括土地開發(fā)、基礎(chǔ)設(shè)施建設(shè)、環(huán)境治理、景觀建設(shè)、辦公、住宅、商業(yè)等諸多開發(fā)項(xiàng)目建設(shè)。各類項(xiàng)目在計(jì)劃編制和施工過程中,往往存在時(shí)間和資源的競爭關(guān)系,導(dǎo)致項(xiàng)目實(shí)際工期存在較大的模糊度,給項(xiàng)目工期預(yù)測和項(xiàng)目進(jìn)度帶來極大困難。首先,根據(jù)科技園區(qū)項(xiàng)目建筑單位的自身特點(diǎn)以及影響工期估值的主要因素,本文根據(jù)模糊理論提出了一種基于梯度模型的關(guān)鍵鏈工期估計(jì)方法,從數(shù)學(xué)意義上表征這種模糊性,獲得具有一定可信程度的工期估計(jì)值,使用該方法解決關(guān)鍵鏈的緩沖區(qū)設(shè)置問題。其次,針對(duì)于不確定性和資源沖突問題,在模糊數(shù)學(xué)的基礎(chǔ)上,引入了補(bǔ)償因子。利用具有一定可信度的工期估計(jì)值建立關(guān)鍵鏈和計(jì)算緩沖區(qū),利用補(bǔ)償因子監(jiān)控和分析可能存在的資源沖突。然后,關(guān)鍵鏈管理方面,針對(duì)傳統(tǒng)關(guān)鍵鏈方法中,緩沖區(qū)的動(dòng)態(tài)消耗行為不易被察覺的情況,本文提出了風(fēng)險(xiǎn)監(jiān)控函數(shù)。使用該函數(shù)和傳統(tǒng)緩沖區(qū)管理方法相結(jié)合,能夠保障管理者提前發(fā)現(xiàn)并處理緩沖區(qū)高速消耗的情況。最后,針對(duì)科技園區(qū)項(xiàng)目進(jìn)度管理中的常見問題,以C工程為實(shí)例,使用該方法建立關(guān)鍵鏈和緩沖區(qū),最后通過在實(shí)施過程中不斷監(jiān)控和分析補(bǔ)償風(fēng)險(xiǎn)系數(shù)的變化來監(jiān)管關(guān)鍵鏈的執(zhí)行過程。項(xiàng)目的實(shí)施經(jīng)驗(yàn)表明,該方法具有良好的可行性。本文針對(duì)影響科技園區(qū)工程進(jìn)度的不確定性因素,利用基于概率統(tǒng)計(jì)分析的模糊評(píng)價(jià)方法,提出更加可靠的緩沖區(qū)計(jì)算方法,建立具有一定可信度的關(guān)鍵鏈進(jìn)度管理法體系,從而解決項(xiàng)目進(jìn)度管理的計(jì)劃編制方法和相關(guān)問題,對(duì)于科技園區(qū)類項(xiàng)目的進(jìn)度計(jì)劃設(shè)置和管理具有一定的指導(dǎo)意義。
[Abstract]:The project of science and technology park includes land development, infrastructure construction, environmental governance, landscape construction, office, housing, business and many other development projects. In the process of planning and construction, there is often a competitive relationship between time and resources in the process of planning and construction, which leads to the existence of a great degree of fuzziness in the actual project period and the project time forecast and project. The progress brings great difficulties. Firstly, according to the characteristics of the construction unit of the Science Park and the main factors that affect the time period valuation, this paper proposes a critical chain time estimation method based on the fuzzy theory, which is based on the gradient model. This method is used to solve the problem of buffer setting in key chains. Secondly, on the basis of fuzzy mathematics, the compensation factor is introduced on the basis of fuzzy mathematics for uncertainty and resource conflict. The key chain and calculation buffer are established by using the estimated time period of certain credibility, and the possible resource conflicts are monitored and analyzed by the compensatory factor. After the key chain management, in view of the situation that the dynamic consumption behavior of the buffer zone is not easy to be detected in the traditional key chain method, the risk monitoring function is proposed in this paper. The combination of this function and the traditional buffer management method can guarantee the manager to find and deal with the high-speed consumption of the buffer zone in advance. Finally, it is aimed at the science and technology park. The common problem in project schedule management is an example of C engineering, which uses this method to establish key chain and buffer zone. Finally, through monitoring and analyzing the change of the compensation risk coefficient constantly during the implementation process, the implementation process of key chain is monitored. The implementation experience of the project shows that the method has good feasibility. This paper is aimed at influencing the technology of science and technology. The uncertain factors of the park project progress, using the fuzzy evaluation method based on the probability and statistics analysis, put forward a more reliable calculation method of the buffer zone, and set up a key chain schedule management system with certain credibility, so as to solve the planning method and related problems of project schedule management, and the progress of the project of science and technology park. The planning and management are of certain guiding significance.
