Based on the given information of time taken to travel from one zone to another, we created a model of the optimum configurations of three, two, and one ambulances in the county, and determined whether the ESC could cover a catastrophe. We started by setting definitions, assumptions, and variables, and then started analyzing the given data to see which ambulances could reach which zones within 8 minutes, to see which configurations could actually cover all 6 zones of the county. Following, with the 13 configurations that could cover the whole county, we analyzed each one based the ambulances’ coverage of people within time constraints, based on data from emergency calls per day and time spent travelling to provide services to the person. With the remaining three ambulances that we determined to cover the same amount of people, we decided the optimum configuration through comparing the spare minutes of each ambulance, with the configuration being placing ambulances in zones 2, 4, and 6, with 97.7% of the people being covered and 6250 people left uncovered. However at the end, because not everyone was covered, three ambulances would not be able to cover everyone. Next, we repeated the process for two ambulances and one ambulance, and determined the configuration to be in zones 2 and 5, and in zone 2 respectively. Two ambulances covered 77.55% of the people and left 60,615 uncovered, and thus could not cover everyone. One ambulance covered 45.83% of the people and left 146,259 people uncovered and thus also could not cover everyone. We continued by trying multiple methods for three ambulances to tackle disasters, and we discovered that the best way to operate the ambulances in its stations was to use the “disaster-saver” method where an ambulance would go to a closest zone and operate there until all calls were dealt with before returning to its original zone. This method covered up to 94.1% of the people but left at least 16,045 people uncovered, so we determined that the ESC alone would not be able to cover a catastrophic event did occur. Although as a whole the county may be fine after the catastrophe, it will most likely have received much help from the state or country it is in. In addition, with the information gathered from researching case studies in places including Japan, Cuyahoga of Ohio, and San Diego, we discovered methods for the county or state to be prepared for catastrophes including floods, earthquakes, and hurricanes.
