Abstract: The selection of emergency alternative affects the efficiency of risk decision making. At present, the mainstream emergency alternative generation methods can be divided into four kinds: “Case-based reasoning”, “Computer algorithm reasoning”, “Prospect theory”and“Multi-factor mathematical model”. According to the differences in emergency decision-making scenarios on the option to choose emergency alternatives, decision needs to be made by designing the optimization based on the emergency alternative generating methods, clearance in different types of emergency decision elements combination, and the applicability of different generation methods, thus alleviating the dilemma of emergency alternative generating method to multiple types of emergencies.

Key words: emergency alternative, generating methods, situational differences
