Under the normal conditions, an optimization model was obtained to achieve the shortest mechanism path in the facilities, the shortest lag time of pushing management and enough repairing time. Under the abnormal conditions, oven number out of sequence, accident state and broken oven were uniformly described as oven number out of sequence. Based on that, an optimization model for the abnormal conditions was established to achieve targets and the least cost of little cycle in recovering process. To deal with these two optimization models, the corresponding coke oven working planning was proposed, i.e., one was under normal conditions, and the other was based on Dijkstra algorithm under abnormal conditions.
