铁路工程建设物资应急调配方案求解算法研究OA

Emergency allocation of engineering materials is an important part of railway engineering logistics and has an important impact on ensuring the scheduled construction of railway line projects.Especially in line construction environments with severe cold and steep terrain,emergencies such as landslides and debris flows often occur.A complete and efficient emergency material supply strategy is required as a guarantee to avoid affecting the construction progress of railway line projects.This paper proposed an emergency material allocation model and its corresponding solution algorithm considering transportation distance and arrival delay time,which could efficiently calculate the optimal material allocation route scheme.The constructed mixed integer programming model adopted the shortest transportation distance and weighted delay time as the objective function and used an algorithm combining adaptive large neighborhood search algorithm,floyd algorithm,and improved Hungarian algorithm to quickly solve the model and obtain the optimal material delivery scheme.Through comparative analysis experiments of multiple calculation examples,the effectiveness of the designed model and algorithm was proved,providing new solution ideas and schemes for engineering material allocation problems in railway emergency scenarios.
