Infrastructure project standard operation cost system research and construction method and application

The invention belongs to the technical field of infrastructure engineering, and particularly relates to an infrastructure engineering standard operation cost system research and construction method and application, and the method comprises the steps: building an engineering early-stage standard operation cost system, and forming a standard operation cost library; establishing a historical actual cost record library; preliminarily calculating the construction cost; dynamically comparing the construction cost fuzzy value with a historical actual cost reference object; dynamically correcting the fuzzy value of the construction cost according to the cost deviation; calculating post-project management cost; according to the standard operation cost system research and construction method, a mode of combining standard cost and operation cost is utilized, a capital construction cost management system is optimized, a construction unit reward and punishment system is defined, the budget management level of a capital co
