The main purpose of the preparation of the railway construction skylight setting plan is to determine the opening time and the opening mode of the construction sunroof according to the transport plan and construction plan,which is an important part of the railway transport organization.Optimizing the construction plan of railway sunroofs is of great significance in guiding construction operations,improving construction quality and efficiency,reducing the impact on train operations,and coordinating the relationship between construction and train operations.Based on the introduction of the construction skylight,this paper summarizes the existing research status and development trends,and inherits the results.At the same time,it points out the existing research deficiencies,summarizes the different types of sunroof classification and adaptability of different sunroof modes.Through the analysis of the factors affecting the railway construction sunroof and its content,based on the artificial intelligence search,cumulative prospect theory and grey target decision,the railway construction sunroof setup scheme is divided into two major blocks: the construction sunroof opening time and the construction sunroof opening model.The content is as follows:(1)Determination of the opening time of construction skylights.Construction open time of sunroof includes construction sunroof duration and start time.The duration of the construction sunroof is limited by the necessary working time for maintenance of public works,maintenance of electrical services,maintenance of the contact network,and establish the minimum model of total capacity loss;the determination of the start time of the construction sunroof uses the artificial intelligence search method in the two-dimensional space of the operation diagram.Search for the best position of the starting node of the sunroof.(2)Confirmation of the construction skylight opening mode.From the analysis of the impact of skylights on traffic organization,capacity,travel speed,construction operation efficiency and safety,based on accumulated prospect theory and grey target decision theory,with the goal of maximizing transport efficiency,a construction skylight setting plan optimization model was established to compare various The advantages and disadvantages of sunroof mode.Combining the above model and algorithm,an example is given.The results show that according to the actual situation,choosing the appropriate construction sunroof opening time and setting mode will help coordinate the increase of transport capacity and improve construction quality and efficiency.
