Method for evaluating economic and technical indexes of engineering project

Abstract

The invention discloses a method for evaluating economic and technical indexes of an engineering project. According to the method, the assisting reviewing function on a transmission and transformation project is achieved by establishing an engineering project key index system and applying an intelligent analyzing method and an engineering project cost key index comparing method. Monitoring and managing of the whole transmission and transformation project reviewing process are achieved in an information-based system from the pre-reviewing of the transmission and transformation project to end reviewing of the transmission and transformation project. The key index system comprises a transformer substation engineering key index and an overhead line engineering key index. According to the intelligent analyzing method, historical engineering similar to target engineering and a general design module are automatically matched by screening engineering project key parameters, the cost difference is visually displayed by comparing the key engineering economic and technical indexes, and data support is provided for evaluation experts to review the project engineering in an intelligentized mode. The method is suitable for reviewing of an evaluation system for the economic and technical indexes of the engineering project.

Description

technical field [0001] The invention relates to an evaluation method of engineering project economic and technical indicators, which belongs to the technical field of engineering project evaluation. Background technique [0002] At present, the provincial power companies under the State Grid Corporation system have successively established their own provincial electric power economic and technological research institutes. After the establishment of provincial economic and research institutes, they gradually began to conduct research and practice on power grid planning, project review, and project cost business integration, informatization, and intelligence. [0003] Because they have different understandings of the development and development direction of power grid planning, project review, engineering design, technology and economics, etc., the provincial companies are in the stage of theoretical research and experimentation, lacking specific solutions and practical exper...

Problems solved by technology

[0004] Because they have different understandings of the development and development direction of power grid planning, project review, engineering design, technology and economics, etc., the provincial companies are in the stage of theoretical research and experimentation, lacking specific solutions and practical experience based on the full-service integration platform. The work only stays in the execution of project review and cost evaluation business processes by manual circulation

[0005] At present, the evaluation management and cost management systems applied in the power industry are limited by the requirements of one unit or one management department. The system has strong functional goals in planning, and it is either used for investment estimation or applied to preliminary design estimates. It cannot comprehensively cover and serve data evaluation at all stages of the project

[0006] Traditional design review methods are generally evaluated based on review management requirements and review experts’ own experience. There is a lack of a set of scientific, reasonable and effective review metrics for various projects, which cannot better standardize design review, hindering the development of design guidance and standardization work. carry out

In the past, the compilation of review opinions was completed by professional experts, and then centralized to the project leader to complete the summary manually, which made the compilation process cumbersome and inefficient

In the traditional review process and data management process, the number of reported materials is too large and too scattered. Manual collection and archiving, low work efficiency, and prone to data loss
