Project-level road infrastructure comprehensive maintenance decision-making method and system

Abstract

The invention provides a project-level road infrastructure comprehensive maintenance decision-making method and system, and the method comprises the steps of determining an analysis object, and obtaining the historical data of the analysis object; classifying the historical data of the analysis object to obtain a classification data matrix; performing prediction analysis based on the classification data matrix to generate a parameter prediction matrix; determining a global optimization objective function, a weight coefficient corresponding to the analysis object and the sub-item treatment cost; and according to the historical data, the parameter prediction matrix, the global optimization objective function, the weight coefficient corresponding to the analysis object and the sub-item treatment cost, carrying out comprehensive maintenance decision calculation to obtain an optimal maintenance scheme and an optimal maintenance opportunity; carrying out fund distribution based on the optimal maintenance scheme, and checking the maintenance effect. The method and the system are suitable for the comprehensive maintenance decision of the technical parameters between different project-level road infrastructure structures and the comprehensive maintenance decision of different technical parameters of the same project-level road infrastructure structure.

Description

technical field [0001] The invention relates to the technical field of road maintenance, and more specifically, to a decision-making method and system for project-level road infrastructure comprehensive maintenance. Background technique [0002] The road maintenance decision-making system is the core of road infrastructure maintenance informatization, and plays an important guiding role in road infrastructure maintenance. [0003] In the structural engineering of highway road infrastructure, maintenance decision-making is an important means to improve structural performance maintenance, and its scientificity and rationality are also increasingly favored and widely discussed in the engineering field. [0004] According to the "Statistical Bulletin on the Development of the Transportation Industry in 2017" by the Ministry of Transport, at the end of 2017, the national road maintenance mileage was 4.6746 million kilometers, accounting for 97.9% of the total road mileage of 4.77...

AI Technical Summary

Problems solved by technology

[0015] Through the analysis of the above methods, the following problems exist in the prior art: the maintenance decision is generally established for a single index parameter, and the single maintenance mode is adopted, and there is no corresponding maintenance decision model between different and / or the same road infrastructure parameters, and The combination of project-level road infrastructure maintenance planning and existing norms is not enough, it is difficult to obtain a scientific and reasonable maintenance plan, and it is difficult to comprehensively evaluate maintenance decisions between project-level road infrastructure structures or between different parameters of the same structure
