针对公路养护管理系统和养护工程造价管理系统在养护工程费用分析和经济分析等方面可能存在功能重合的问题,分析了网级养护管理系统和项目级养护管理系统的造价管理功能特点,并利用灰色关联度分析法进行了项目级养护管理系统与可行性研究之间的比较,从而明确了公路养护管理系统在公路养护工程造价管理体系中的功能定位。结果表明:项目级养护管理系统在大修工程、专项工程或改建工程时相当于项目建议书或初步可行性研究,具有初步估算和经济评价的功能,与它们的工程可行性研究功能不重合,而在中小修时则相当于概算的功能;网级公路养护管理系统则具备养护规划阶段的养护工程造价管理功能。
In view of the possible overlapping of functions in the maintenance cost analysis and economic analysis of highway maintenance management system and maintenance project cost management system, the cost management functions of the network-level maintenance management system and project-level maintenance management system are analyzed. Correlation analysis method was compared between project-level maintenance management system and feasibility study, so as to clarify the function of highway maintenance management system in the highway maintenance project cost management system. The results show that the project-level maintenance and management system is equivalent to the project proposal or preliminary feasibility study in the overhaul project, special project or reconstruction project with the functions of preliminary estimation and economic evaluation, which do not coincide with their project feasibility study functions. In the small repair time is equivalent to the estimated function; network-level road maintenance management system has the conservation planning stage maintenance project cost management functions.
