(2.5/5.0) A local firm concentrates the ambulances of an small-sized city in Colombia in a agreement according to which the ambulances operate following the schedule provi- ded by the firm. During the peak hour of previous Saturday the firm received simultaneous 10 calls for service (i.e., A, B, C, D, E, F, G, H, I, J). They had this list of available ambulances and the estimated travelling time (in minutes) from the current location of each of the ambulances to the location of the services: Services B C D E F G H I J 13 31 25 3 4 6 21 22 24 23 34 12 18 15 12 27 23 25 8 21 19 7 8 33 31 19 29 11 14 27 33 28 18 24 34 10 17 32 9 19 24 24 10 8 26 19 15 15 5 6 25 19 21 26 3 14 34 5 19 8 33 29 4 24 31 34 28 7 11 4 27 9 8 34 24 21 34 19 5 3 12 12 29 25 19 13 23 21 30 14 22 22 4 32 6 27 23 5 13 29 31 38 14 20 22 18 5 4 7 33 6 12 5 18 31 17 35 32 19 26 31 21 36 23 28 27 15 39 5 4 19 14 24 18 15 8 21 30 9 10 37 27 20 19 32 12 29 8 Amb A 1 32 2 14 3 4 5 6 7 8 9 10 11 12 13 14 15 (a) (0.5/5.0) Currently, they are forced to select the am- bulances to provide the services following the discipline FIFO (First In First Out), that is, the first ambulan- ce on the list will get the first service to be requested.
