【摘要】：由于電廠冷卻塔在施工過程中技術(shù)要求高且高處施工較多,面臨的施工風(fēng)險(xiǎn)復(fù)雜多變,如果未認(rèn)清、評(píng)估、分析和控制好風(fēng)險(xiǎn)因子,將會(huì)給冷卻塔項(xiàng)目施工帶來巨大的安全隱患。本研究將六西格瑪管理的DMAIC模型運(yùn)用到冷卻塔項(xiàng)目施工安全風(fēng)險(xiǎn)管理中,以期豐富冷卻塔項(xiàng)目施工安全風(fēng)險(xiǎn)管理方式,使冷卻塔項(xiàng)目施工安全風(fēng)險(xiǎn)管理更加科學(xué)化和流程化。DMAIC模型通過定義(Define)、測(cè)量(Measure)、分析(Analysis)、改進(jìn)(Improve)和控制(Control)五個(gè)階段來認(rèn)識(shí)問題、量化問題、分析原因,處理問題并監(jiān)控問題,對(duì)安全風(fēng)險(xiǎn)管理研究具有較好的借鑒意義。研究以GC電廠冷卻塔工程項(xiàng)目為例,探討其施工安全風(fēng)險(xiǎn)管理的DMAIC流程,其中:“定義”階段主要任務(wù)是充分了解冷卻塔施工項(xiàng)目安全風(fēng)險(xiǎn),對(duì)各種問題進(jìn)行識(shí)別。在定義出電廠冷卻塔施工安全風(fēng)險(xiǎn)一般清單的基礎(chǔ)上,根據(jù)GC電廠冷卻塔工程項(xiàng)目特點(diǎn),最終辨識(shí)出19個(gè)風(fēng)險(xiǎn)類型指標(biāo)和75個(gè)關(guān)鍵因子;“測(cè)量”階段主要任務(wù)是度量出安全風(fēng)險(xiǎn)的大小,為找出問題的原因提供事實(shí)依據(jù)與線索。以關(guān)鍵的安全風(fēng)險(xiǎn)因子為依據(jù),構(gòu)建出了GC電廠冷卻塔項(xiàng)目施工安全風(fēng)險(xiǎn)評(píng)價(jià)指標(biāo)體系,采用層次分析法確定評(píng)價(jià)指標(biāo)的權(quán)重,模糊綜合評(píng)價(jià)法評(píng)價(jià)此項(xiàng)目安全風(fēng)險(xiǎn)等級(jí),最后測(cè)得GC電廠冷卻塔項(xiàng)目的施工安全風(fēng)險(xiǎn)綜合評(píng)價(jià)值為3.102∈(2,4],屬安全風(fēng)險(xiǎn)較低級(jí);“分析”階段主要任務(wù)是找出哪些安全風(fēng)險(xiǎn)因素對(duì)安全風(fēng)險(xiǎn)度量的結(jié)果影響較大。研究表明,對(duì)GC電廠冷卻塔項(xiàng)目的施工安全風(fēng)險(xiǎn)影響較大的關(guān)鍵安全風(fēng)險(xiǎn)因素主要表現(xiàn)為人的因素和管理因素;“改進(jìn)”階段主要任務(wù)是提出糾偏措施主動(dòng)地降低安全風(fēng)險(xiǎn)發(fā)生和損失。為了盡可能全面地降低GC電廠冷卻塔項(xiàng)目施工安全事故的發(fā)生,除了從人的因素和管理因素兩大方面以及二級(jí)安全風(fēng)險(xiǎn)因素中對(duì)冷卻塔項(xiàng)目施工安全影響較大的安全風(fēng)險(xiǎn)因素提出了改進(jìn)措施,也從物的因素、方案和技術(shù)因素、環(huán)境因素這些方面中對(duì)項(xiàng)目的安全風(fēng)險(xiǎn)影響較大的因素提出了具體的應(yīng)對(duì)措施;“控制”階段主要任務(wù)是監(jiān)督安全風(fēng)險(xiǎn)改進(jìn)措施執(zhí)行情況,反饋安全風(fēng)險(xiǎn)改進(jìn)措施的實(shí)施效果。在進(jìn)行GC電廠冷卻塔項(xiàng)目施工安全風(fēng)險(xiǎn)控制中,如果安全改進(jìn)措施沒有很好地被實(shí)施,此時(shí)就需要整理和修改改進(jìn)措施并重新實(shí)施改進(jìn)措施,回到DMAIC流程中的源頭,通過不斷的有限循環(huán)監(jiān)控,確保此體系能夠?qū)崿F(xiàn)持續(xù)改進(jìn)績效。本研究嘗試基于DMAIC模型對(duì)電廠冷卻塔項(xiàng)目施工安全風(fēng)險(xiǎn)管理流程進(jìn)行設(shè)計(jì)與改進(jìn),一定還存在諸多不足之處,但研究表明,六西格瑪管理的DMAIC模型可以運(yùn)用到電廠冷卻塔項(xiàng)目施工安全風(fēng)險(xiǎn)管理中并得到項(xiàng)目管理者的肯定,可為冷卻塔項(xiàng)目施工安全風(fēng)險(xiǎn)管理提供另一思路選擇。
[Abstract]:As the power plant cooling tower in the construction process of high technical requirements and high construction more, construction risk facing complex, if you do not recognize, evaluate, analyze and control risk factors, will bring huge risk to the safe cooling tower construction project. In this study, six sigma management, DMAIC model is applied to the construction safety risk management the cooling tower project, in order to enrich the cooling tower project construction safety risk management, the risk management of construction project of cooling tower is more scientific and standardized by defining the.DMAIC model (Define), (Measure) measurement, analysis and improvement (Analysis) (Improve) and control (Control) five stages to understand a problem and the quantization problem, analyze the causes, problems and monitoring, is a good reference for the study of safety risk management. The research on GC power plant cooling tower project as an example, discusses its construction safety The risk management of the DMAIC process, including: "the main task is to fully understand the definition of" cooling tower construction project safety risk, to identify various problems. In defining the foundation of cooling tower construction safety risk list, according to the characteristics of GC power plant cooling tower project, eventually identified 19 types of risk indicators and 75 a key factor; "the main task of measuring stage is a measure of security risks, to provide evidence and clues to find out the cause of the problem. The key to safety risk factor as the basis, build a GC power plant cooling tower project construction safety risk evaluation index system, using AHP to determine the weight of evaluation index. Fuzzy comprehensive evaluation method to evaluate the risk grade of this project, comprehensive evaluation of construction safety risk and finally measured GC power plant cooling tower project value is 3.102, (2,4], is a security risk The lower level; "analysis" stage the main task is to find out what influence the safety risk factors of safety risk measurement results greatly. The study shows that the construction safety risk of cooling tower project GC power plant key safety risk factors larger mainly for human factors and management factors; "improved" stage the main task is to put forward corrective measures take the initiative to reduce the security risk and loss. In order to reduce the GC power plant cooling tower project construction safety accidents as much as possible, apart from the human factors and management aspects of the two and two levels of safety risk factors of cooling tower project construction safety risk factors affecting the safety of large factors put forward the improvement measures. The material, design and technical factors, put forward specific measures on project safety risk factors the influence of these environmental factors; control The main task is the supervision system "safety risk measures to improve the implementation of the feedback effect, safety risk improvement measures. In the construction safety risk control GC power plant cooling tower project, if the security measures were not well implemented, you need to organize and modify the improvement measures and re implementation of improvement measures, back to source DMAIC in the process, through continuous finite cyclic monitoring, to ensure that the system can achieve continuous improvement performance. This study attempts to DMAIC model design and improvement process of construction safety risk management based on the project of a power plant cooling tower, there are still many shortcomings, but research shows that DMAIC model of six Sigma management applied to construction safety risk the management of power plant cooling tower project and project managers must, for risk management of construction projects to provide a cooling tower Choice of ideas.
