Abstract
The selection of central emergency shelter site is the key to setting emergency shelter system in cities or towns. Nine central emergency shelter indexes have been examined based on evaluation indicators including land safety, size of site and disaster prevention and rescue facilities, and thus evaluation criteria are established. This paper proposes a single-object location model based on the weights of known properties of an ideal point according to the criterion of pessimism. This model can reduce decision-making risks and simplify the process of finding a solution. Finally, the effectiveness of this model is tested taking the selection of a central emergency shelter in a city as an example.
