Selecting construction schemes of the building engineering project is a complex multiobjective optimization decision process, in which many indexes need to be selected to find the optimum scheme. Aiming at this problem, this paper selects cost, progress, quality, and safety as the four first-order evaluation indexes, uses the quantitative method for the cost index, uses integrated qualitative and quantitative methodologies for progress, quality, and safety indexes, and integrates engineering economics, reliability theories, and information entropy theory to present a new evaluation method for building construction project. Combined with a practical case, this paper also presents detailed computing processes and steps, including selecting all order indexes, establishing the index matrix, computing score values of all order indexes, computing the synthesis score, sorting all selected schemes, and making analysis and decision. Presented method can offer valuable references for risk computing of building construction projects.
选择建筑工程项目的施工方案是一个复杂的多目标优化决策过程，在此过程中需要选取众多指标以找出最优方案。针对这一问题，本文选取成本、进度、质量和安全作为四个一级评价指标，对成本指标采用定量方法，对进度、质量和安全指标采用定性与定量相结合的方法，并综合工程经济学、可靠性理论和信息熵理论，提出一种新的建筑工程项目评价方法。结合实际案例，本文还给出了详细的计算过程和步骤，包括选取各级指标、建立指标矩阵、计算各级指标得分值、计算综合得分、对所有选定方案进行排序以及进行分析和决策。所提出的方法可为建筑工程项目的风险计算提供有价值的参考。
