冻结工程中,影响施工工期的各项技术参数在施工前主要是依靠过去施工的经验或者设计方所指定的数据。而施工时各项技术参数对工期的影响并不能立刻显现出来,需要一个周期才能达到平衡点。采用灰色关联度分析方法对冻结工程工期技术参数进行优化,建立了模型并较好地对各个参数进行了预测。所得预测值较为真实地反映了实际情况,并通过实时调整施工中的参数,进行成本和工期的优化,证明了该方法的合理性与有效性。
In the freezing project, the technical parameters that affect the construction period mainly depend on the experience of past construction or the data specified by the design side before construction. The construction of the technical parameters of the duration of the impact and can not be immediately apparent, need a cycle to reach the balance point. The method of gray relational analysis was used to optimize the technical parameters of the frozen construction period, the model was established and the various parameters were predicted well. The predicted values reflect the actual situation more truthfully, and the cost and duration are optimized by real-time adjustment of the parameters in construction, which proves the rationality and effectiveness of the method.
