The invention discloses an operation and maintenance work order scheduling management method and system in an electric power telecommunication field. The method comprises steps of 1, work order and worker information acquisition: acquiring all types of operation and maintenance work orders and operation and maintenance worker information, wherein the operation and maintenance work orders comprise task identifiers, task categories, task work procedures, continuous time of accomplishing of each work procedure and task grade information, and the operation and maintenance worker information comprise operation and maintenance worker identifiers, operation and maintenance skills, skill coefficients of each operation and maintenance skill and worker available state information; 2, task and worker matching analysis: based on the work orders and worker information, calculating a task difficulty coefficient of each project, operation ability coefficient of each operation and maintenance worker and a corresponding single worker task matching degree; and 3, work order scheduling: based on the single worker task matching degree relative to each operation and maintenance worker, distributing each task to the corresponding operation and maintenance worker. According to the invention, based on the task matching degree, the operation and maintenance tasks are distributed to corresponding operation and maintenance workers, so the method is vivid and easy to use, operation and maintenance efficiency can be effectively improved and operation and maintenance cost can be reduced.
