In the process of emergency rescue, due to the lack of optimization of collaboration mode between resource entities such as emergency teams and the lack of high matching degree of dispatch, this study proposes a method based on case base and plan base to calculate the skill contribution degree of emergency execution entities, the relationship strength and collaboration degree between entities, and to mine the high collaboration mode among emergency entities by using the high collaboration algorithm of emergency entity trajectory mining. The completeness and matching degree of high emergency team scheduling management provide basic data. At the same time, based on the activity trajectory and activity continuity of entities, high continuity activities can be excavated, which lays the foundation for decision-making of emergency response sequence in rescue. The experimental results show that the coordination ability of the same and different emergency entities varies with the number of collaborations, which deviates greatly from the results of previous empirical decision-making. It provides important data support for the rational dispatch of emergency teams and the formulation of efficient emergency plans, and has practical value.
