公路养护管理系统在公路养护工程造价管理体系中的定位研究

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。

A Study on Location of Highway Maintenance Management System in Highway Maintenance Engineering Cost Management System

In view of the possible shortage that highway maintenance management system and maintenance engineering cost management system have the same function in cost analysis and economical analysis of maintenance project,the characteristics of cost management functions for maintenance management system in web level and item level are analyzed,then the item level maintenance management system and feasibility study by gray correlation analysis method are compared,so the function location of highway maintenance management system in cost management of highway maintenance system is confirmed.The results show that the item level maintenance management system is equal to the proposed task of project or the preliminary feasibility study when used in heavy maintenance,special project and rebuilding project,it has preliminary estimation and economical appraisal functions and hasn't the same functions with the feasibility study.At the same time,it has the budget function in medium and minor maintenances.In addition,the web level highway maintenance management system has the cost management function of maintenance project in the phase of maintenance planning.
