摘要 目标工程建设中存在部分企业成本意识单薄,忽略成本管理,成本超支情况普遍存在。为了深入研究工程成本控制手段,改进目前工程成本控制中普遍存在偏重预先控制、过度依赖专家经验的情况,深入研究了基于ISM-BN组合模型的工程成本中人工成本超支预测,即通过对人工成本关键影响因素的识别和对他们之间逻辑关系的梳理,形成解释结构模型,并使用BN在事前对人工成本概率进行推测,并以GWZX项目为例对人工成本超支预测模型进行了验证,论证了模型的科学性、合理性,为工程施工成本控制提供指导依据,减少成本超支现象的发生。 Due to lack of cost-conscious and low level of cost management, cost overruns happen frequently. To improve cost control, the paper analyzes labor cost overrun based ISM-BN by identifying key factors and logical relationships. Artificial BN is used to predict cost trend. The labor cost overruns prediction model is validated by a real project. The model can provide guidance to reduce cost overruns phenomenon.
