Abstract:
The construction cost of sixteen freeways in Shaanxi province was analyzed by statistics, the concept to cost ratio and per unit cost were put forward, the cost composition interval was built and the evaluation index level of freeway cost proportion and method to determine the standards were put forward, the quantification decision model of cost control based on DEA was set up. The application results show that this model can evaluate each unit cost of the new freeway. When evaluating a new highway construction cost, the cost items whose cost proportion evaluation results are below medium and DEA model evaluation is invalid should be taken as key auditing and controlling objects. 7 tabs, 1 fig, 9 refs.
