he solution of this problem satisfies all the goals; that is, with an adequate distribution of the ordinary and extraordinary operations, it is possible to accomplish the desired levels. In this solution, there is no spare capacity within the service. This can be seen by multiplying,within each month, the number of ordinary operations of each process (Table 8) by the mean duration of these operations (Table 1). The results for each month differ from the total assigned times (Table 5) in just a few minutes. Therefore, a redistribution of the resources hasbeen achieved, and, as a result, there is an improvement of the ordinary activity. On the other hand, there is spare capacity in other services, as can be seen in Table 9, which would suggest a redistribution of the installed capacity (especially the operation theatres’ time) in orderto get a more efficient performance
