In fact, distribution system is the most downstream electric power system, and is directly related to the customer’s electricity consumption. However, due to its wide spread in area and being easily affected by nature phenomena such as weather, electric network fault is unavoidable. Whenever faults occur, it is nearly impossible to have enough workers to carry out emergency repair. The duration of power outage would be extended and induces many complaints from the customers. Therefore, to reduce the outage time and the affected number of customers are the essential issues for improvement on power distribution system. Taipower designs the Outage Management Aid System to shorter outage duration, reduce the affected number of customers and increase the reliability of power supply. The system receives incoming calls from customers and obtains outage information to assist the dispatcher for fault handling. The customer’s related transformer/feeder and the outage information can be linked together, and can be used to judge the possible locations of faults and to provide related information to the customers in real-time. By the aid of the system, information about fault location as well as fault condition could be immediately available. The customer’s enquires could be replied much more clearly and firmly so as to enhance the customer services. In order to command the condition of the accidents of power distribution line effectively, to accelerate the procedure to rush to repair breakdowns caused by the disaster and to answer the query phones from users rapidly while nature disaster has happened, Outage Management Aid System has been improved and the function for missions assignment is added. Outage Management Aid System registers the accidents of power failure according to the phone number or name of the users calling, the electric power number or address of the place where power failured. Furthermore, it assigns distribution line inspectors to inspect on site and record the accidents as a basis for assignment. But while significant nature disaster happens, such as typhoon, earthquake, etc, the power failure caused by the accidents of power distribution line would increase tremendously. It is important to arrange the priority to rush to repair such a mass of breakdowns caused by the disaster according to the man power available, so that the number and duration of power failures could be decreased as soon as possible. The factors which should be considered include the number of users of power failure, important users（such as hospitals, important institutions for directing, police station,etc）, the journey, the security and so on. These factors would be affected by the time factors happened and so that the priority for the mission assignments, too. This thesis is forced on the mission assignments for the accidents of power failure by linear programming theory.Experiments are performed to validate the effectiveness of the system.
