The field scheduling is always a difficult point of power grid operation. How to carry out the management and allocation of human resource effectively is the foundation of power grid corps scheduled tasks to be completed timely and efficiently. This paper introduces a kind of automatic human resource distribution model and computing system based on artificial intelligence: We draw from the Job-shop theory; combine with genetic algorithm to carry out human resource scheduling to achieve the optimization target of the maximum completion time is the shortest and the delayed loss minimum. Finally, through the example analysis to prove the feasibility of the model and algorithm.
