Emergency response study of space launch based on Decision Network Planning

Space launch is a complex project with high risk, and failure of space launch may cause a great loss to people's life, property and important facilities. Thus a resonable and effective emergency response program is critical and important for space launch. First, a Decision Network Planning (DNP) method is proposed to describe logic relations of emergency response procedures, based on which the logical reasonability and rigor, coordination of several involved departments, timeliness of emergency measures and sufficiency of resources guarantee are evaluated. Then, the critical path and resource guaranteed rate are calculated to analyze the degree of control in the emergency process of space launch failure. Last, a case of filling leakage is used to show the helpfulness of the proposed method.
