One of these models, called the Double Standard Model (DSM) maximizes double demand coverage with a fixed number of ambulances. A dynamic version of DSM was developed and tested on data from the Island of Montreal. The static version was successfully applied to data from Montreal, Austria and Wallonia. \itemrv{~} \itemcc{} \itemut{} \itemli{doi:10.1007/978-3-540-92944-4\_12} \end
