Calculation of Gains and Losses
Gains and losses reflect decision makers’ different psychological behavior, (gains: risk aversion, losses: risk seeking), which are obtained according to the reference point, \\( R_{im} \\), and the predefined effective control scope, \\( E_{jm} \\), of different emergency alternatives.
Because both the reference points and the predefined effective con.

Calculation of Overall Prospect Values
For the sake of simplicity, the attribute weights are provided by the decision maker in this study.
By using the simple additive weighting method, the overall prospect value of each alternative can be obtained, that is, The overall prospect value \\( O_{ij} \\) reflects whether the alternative is adequate for coping with the emergency situation or no.
,
Calculation of Prospect Values
Let \\( {\\text{GM}}_{i} = (G_{ijm} )_{J \\times M} \\) be the gain matrix regarding the i-th emergency situation, \\( {\\text{LM}}_{i} = (L_{ijm} )_{J \\times M} \\) be the loss matrix regarding the i-th emergency situation.
According to prospect theory, the magnitude of gains and losses is measured by value function, let \\( {\\text{VM}}_{i} = (v_{ijm} )_{.

Framework Definition
The following notations are used in the proposed method: 1. \\( A = \\left\\{ {A_{1} ,A_{2} , \\ldots ,A_{J} } \\right\\} \\): set of alternatives, where \\( A_{j} \\) denotes the j-th alternative, \\( j = 1,2, \\ldots ,J \\). 2. \\( S = \\left\\{ {S_{1} ,S_{2} , \\ldots ,S_{n} } \\right\\} \\): set of different emergency situations, where \\( S_{i} \\) denotes the i-t.

Information Collection
When an emergency event occurs, it may evolve into different possible emergency situations because of the dynamic features of emergency events.
Before making a decision, it is necessary for the decision maker to collect related information (possible situations, possible losses caused by different possible situations, and so on).
According to differ.

Should an emergency manager make a command decision alone?
As an emergency manager, you work often in situations that require a high degree of coordination.
These cases call for a group decision-making process.
There are other times, however, when you must make a command decision alone.
Several factors affect whether a decision should be made by an individual or a group.

What is a public health emergency decision?
Public health emergency decisions are explored to ensure the emergency response measures in an environment where various emergencies occur frequently.
An emergency decision is essentially a multi-criteria risk decision-making problem.
,
What is emergency decision making?
Decision makingis making choices at each step of the problem-solving process.
The emergency decision-making process begins well before disaster strikes.
EOPs and SOPs provide the foundation for decision making during emergencies.

Which factors affect the final emergency response during coordinated decision-making?
The complementarity of resources between departments, the convenience of communication, and the degree of personnel collaboration will affect the final emergency response during the coordinated decision-making between different departments.
The selection process of the multi-department emergency decision is described as the structure in Fig. 4.
