【摘要】：近年來(lái),隨著經(jīng)濟(jì)的發(fā)展,建筑規(guī)模逐漸擴(kuò)大,許多的企業(yè)開始關(guān)注戰(zhàn)略實(shí)施方法,對(duì)于項(xiàng)目群管理越來(lái)越重視。而建筑業(yè)作為高風(fēng)險(xiǎn)行業(yè),由于建設(shè)規(guī)模大,整個(gè)建設(shè)過(guò)程中參與人員多,安全問(wèn)題十分嚴(yán)峻,事故的發(fā)生對(duì)自然環(huán)境、社會(huì)經(jīng)濟(jì)和人民生活都會(huì)產(chǎn)生嚴(yán)重的影響。導(dǎo)致事故的根源為施工現(xiàn)場(chǎng)中潛在的危險(xiǎn)源,但是,國(guó)內(nèi)外目前對(duì)于項(xiàng)目群中危險(xiǎn)源的研究較少。因此,本文以銅川市某小區(qū)建設(shè)為依托,對(duì)項(xiàng)目群危險(xiǎn)源管理進(jìn)行了研究。首先分析了項(xiàng)目群與單項(xiàng)目危險(xiǎn)源管理的異同,建立了項(xiàng)目群危險(xiǎn)源辨識(shí)的矩陣型組織結(jié)構(gòu)及危險(xiǎn)源辨識(shí)數(shù)據(jù)庫(kù)。在項(xiàng)目壽命周期理論及PDCA循環(huán)理論的基礎(chǔ)上,總結(jié)出了項(xiàng)目群危險(xiǎn)源辨識(shí)的步驟,并繪制了從施工前、施工中、事故后及施工后危險(xiǎn)源辨識(shí)的流程圖。接下來(lái)從縱向及橫向的角度對(duì)項(xiàng)目群建設(shè)過(guò)程中存在的危險(xiǎn)源進(jìn)行評(píng)價(jià)。在縱向評(píng)價(jià)中,結(jié)合了馬爾科夫理論、模糊數(shù)學(xué)理論及可靠性理論,建立了基于可靠性分析的模糊馬爾科夫模型。在橫向評(píng)價(jià)中,構(gòu)建了項(xiàng)目群中多個(gè)項(xiàng)目之間危險(xiǎn)源的相關(guān)性評(píng)價(jià)指標(biāo)體系,建立了基于信息熵與D-S證據(jù)理論的相關(guān)性評(píng)價(jià)模型。最后建立了項(xiàng)目群危險(xiǎn)源控制組織結(jié)構(gòu),從不同的角度對(duì)危險(xiǎn)源的控制方式進(jìn)行了分類,總結(jié)了危險(xiǎn)源的控制方法,對(duì)危險(xiǎn)源按照危險(xiǎn)程度進(jìn)行了分級(jí)并闡述了危險(xiǎn)源分級(jí)控制。研究結(jié)果表明:將本文的危險(xiǎn)源管理體系應(yīng)用到項(xiàng)目群建設(shè)過(guò)程當(dāng)中,可以有效的解決項(xiàng)目群危險(xiǎn)源管理中存在的問(wèn)題,從而降低安全事故的發(fā)生,取得良好的經(jīng)濟(jì)和社會(huì)效益。文章研究成果可以為類似項(xiàng)目的危險(xiǎn)源管理提供參考。
[Abstract]:In recent years, with the development of economy and the expansion of construction scale, many enterprises begin to pay attention to the method of strategic implementation, and pay more and more attention to project group management. The construction industry as a high-risk industry, because of the large scale of construction, the entire construction process involved in a large number of people, security problems are very serious, accidents on the natural environment, social economy and people's lives will have a serious impact. The root cause of the accident is the potential hazard source in the construction site. However, there is little research on the hazard source in the project group at home and abroad. Therefore, based on the construction of a small district in Tongchuan City, this paper studies the risk source management of project group. Firstly, the similarities and differences between project group and single project risk source management are analyzed, and the matrix organization structure and risk source identification database of project group risk source identification are established. On the basis of project life cycle theory and PDCA cycle theory, the steps of hazard source identification of project group are summarized, and the flow charts of hazard source identification before, during, after accident and after construction are drawn. Then the risk sources in the construction of the project group are evaluated from the vertical and horizontal angles. In longitudinal evaluation, a fuzzy Markov model based on reliability analysis is established by combining Markov theory, fuzzy mathematics theory and reliability theory. In the horizontal evaluation, the correlation evaluation index system of multiple projects in the project group is constructed, and the correlation evaluation model based on information entropy and D-S evidence theory is established. Finally, the organization structure of the project group risk source control is established, the control methods of the hazard source are classified from different angles, and the control methods of the hazard source are summarized. The hazard source is classified according to the degree of danger and the classification control of hazard source is expounded. The results show that the application of the risk source management system to the project group construction process can effectively solve the problems in the project group risk source management, thereby reducing the occurrence of safety accidents. To achieve good economic and social benefits. The research results can provide a reference for the risk management of similar projects.
