Alternative 3: hire three more doctors and three more nurses, and schedule more
resources in the day and evening shifts (Table 8).

Alternative 4: Schedule the maximum number of doctors and nurses for each shift
(5 doctors and 5 nurses). Although this solution may be neither feasible nor
implementable, it may show the performance of the system when resources are
maximized for drawing up some contingencies (Table 9).

This step of the CBR methodology requires stakeholders’ involvement due to their
familiarity with their system, and their ability to address concerns that may be critical to
the interpretation of the simulation model and its outputs.
The adopted solution was coded (assigned a case number), indexed as an
optimization case, and was then added to the case-base.

CBR METHODOLOGY VERIFICATION AND VALIDATION

Although there exist several techniques to validate simulation models (animation,
event validity, traces, face validity, and historical data validation), the latter technique
