【摘要】：為了更合理地選取公路工程施工定額測定對象,針對目前定額測定對象確定時缺乏定量化方法的問題,在假定定額的測定對象均能滿足施工要求的正常條件前提下,采用綜合評價公路工程施工水平的方法對施工定額測定對象選擇進(jìn)行研究。從項目部、施工班組、施工現(xiàn)場條件3方面分析了項目施工水平的影響因素,在此基礎(chǔ)上結(jié)合德爾菲法依據(jù)專家多次評分結(jié)果建立了包含目標(biāo)層、一級指標(biāo)及二級指標(biāo)的公路工程施工水平影響因素三層次評價指標(biāo)體系;分別采用主觀賦權(quán)的IAHP法和客觀賦權(quán)的粗糙集法計算得到各自的指標(biāo)權(quán)重值,且基于此權(quán)重值建立了IAHP-粗糙集綜合評價模型,利用組合權(quán)重對待選測定對象的生產(chǎn)水平進(jìn)行定量化綜合評價,并根據(jù)評價結(jié)果來進(jìn)行定額測定對象的選取,提高了施工定額測定對象選擇與定額水平評價的可靠性。通過某施工企業(yè)制定定額時,對能滿足正常施工條件的7個項目采用IAHP-粗糙集綜合評價模型進(jìn)行實例驗證,驗證結(jié)果表明,綜合評價結(jié)果能夠較為準(zhǔn)確地反映實際施工生產(chǎn)水平。
[Abstract]:In order to select the measuring object of the construction quota of highway engineering more reasonably, aiming at the lack of quantitative method in the determination of the quota measuring object at present, under the assumption that the measuring object of the quota can meet the normal condition of the construction requirement, The method of synthetically evaluating the construction level of highway engineering is used to study the selection of the target for determining the construction quota. This paper analyzes the factors influencing the construction level of the project from three aspects: the project department, the construction team and the construction site conditions. On this basis, combining with Delphi method, the inclusion target layer is established on the basis of the result of multiple evaluation by experts. The three-level evaluation index system of the influencing factors of highway engineering construction level of the first grade index and the second grade index is calculated by using the IAHP method of subjective weight and the rough set method of objective weight, respectively, and the weight values of each index are calculated. The IAHP- rough set comprehensive evaluation model is established based on the weight value. The combined weight is used to evaluate the production level of the selected objects, and according to the evaluation results, the quota measurement objects are selected. The reliability of target selection and quota level evaluation is improved. The IAHP- rough set comprehensive evaluation model is used for 7 projects which can meet the normal construction conditions when a certain construction enterprise formulates the quota. The results show that, The comprehensive evaluation results can accurately reflect the actual construction production level.
