摘要
采用PPP模式建设和运营地下综合管廊可以缓解政府的财政压力.PPP模式分类众多,各个模式的运作方式均存在差异,采用合适的PPP模式对地下综合管廊项目进行建设和运营十分必要.提出PPP模式的两阶段模式选择模型.首先,分别建立二级和三级PPP模式选择的指标体系,应用BP神经网络为具体的地下综合管廊项目选择出合适的二级PPP模式;然后,运用改进的TOPSIS法,即直觉梯形模糊TOPSIS法求得选出的二级PPP模式下各三级模式的贴近度,基于贴近度大小对三级PPP模式进行排序;最后以郑州市地下综合管廊PPP项目为例,通过建立的两阶段模式选择模型对该项目适宜采用的PPP模式进行选择.结果表明,模型的预测性能良好,所得模型对于地下综合管廊PPP项目进行模式选择具有较强的指导意义和操作性.
Using PPP mode to construct and operate utility tunnel can alleviate the financial pressure of government.PPP mode has many classifications and each way of working of them is different,so it is necessary to construct and operate the utility tunnel project with the appropriate PPP mode.A two-stage mode selection model for PPP mode was proposed.Firstly,the index system of selection of secondary and tertiary PPP mode is established respectively,by using BP neural network to choose the appropriate secondary PPP mode for specific utility tunnel project.Then,an improved TOPSIS method was used,namely intuitionistic trapezoidal fuzzy TOPSPS method to find the closeness to the tertiary modes which belong to the selected secondary PPP mode and then sort the tertiary PPP mode by closeness.Finally,the effectiveness of the PPP mode selection model is further illustrated by an example.The results show that the model has good predictive and strong guiding significance and operability for the mode selection of utility tunnel PPP project.
