AI Technical Summary

Problems solved by technology

The integer programming model can efficiently solve the exact solution when the scale of the problem is not too large. However, as the scale of the problem expands, the solution time increases exponentially; the widely used genetic algorithm, due to the nature of the genetic algorithm, cannot guarantee that it can solve the problem in a limited time. As another special genetic algorithm, the weighting method cannot guarantee to find a complete Pareto optimal solution.

Embodiment Construction

[0041] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the above technical solutions will be further described below in conjunction with the illustrations.

[0042] As shown in the figure, a road surface maintenance and renovation scheduling method that takes into account both performance improvement and budget utility, the road category S only includes one category. The road condition I is divided into two grades 1 and 2, wherein grade 1 is better than grade 2, accounting for 70% and 30% respectively. The planning year is 1 year, budget B 1 =90, the minimum requirement for the proportion of road surfaces in the first-class condition in the road network X * = 90%. The maintenance measures are divided into 1 renovation and 2 maintenance. The road condition transformation matrix under different measures is shown in Figure 2.

Abstract

The invention discloses a road surface maintenance and renovation timing arrangement method taking into account both performance improvement and budget utility. The equipment of the method includes a storage module for storing map data information and a data processing module, which are obtained in two steps according to road network establishment and timing arrangement. As a result, an efficient and comprehensive solution method can greatly save time, improve the work efficiency of managers, provide a strong guarantee for the further development of follow-up decision-making work, and provide a basis for scientifically rational and optimal selection of maintenance and renovation plans.

Description

technical field [0001] The invention relates to the field of transportation, in particular to a method for arranging road surface maintenance and renovation schedules. Background technique [0002] Road pavement maintenance and renovation is one of the most expensive activities in transportation infrastructure management. The construction of transportation infrastructure has played a strong role in promoting the development of my country's economy and is a powerful guarantee for the smooth progress of economic activities. However, with the increase in the amount of road construction, a large number of roads that have been built will inevitably wear out, facing the problem of road maintenance and renovation. The road section and timing of maintenance, how to coordinate the maintenance plan and the maintenance measures selected are all issues that need to be considered by managers. [0003] Traffic scholars often build and solve two types of models based on the information t...
