Abstract

The present invention relates to a method, device and storage medium for sequencing and managing rail transit line resources. The method includes the following steps: step S 101 : analyzing a trackside line loop deadlock scenario and establishing a static deadlock prevention policy; step S 102 : reasonably making an operation plan to avoid resource deadlock loop wait; step S 103 : applying for all required resources for each train at a time; step S 104 : establishing an operation task order verification mechanism; and step S 105 : monitoring and executing an operation task. Compared with the prior art, the present invention can reduce the idle time of the line resources, improve the utilization rate of the line resources, and avoid the problems of operation deadlock and the mismatch between an actual train operation task and the operation plan.
