Configuration of the input parameters of the simulation model (E1).

Input parameters configuration
Request Received Rate.  The pattern of behavior of orders received after the launching of a special offer is modeling by the ramp shown in Figure 2. The following input parameters configure this ramp:
(i) Initial  Value: 500 orders/minute.
(ii) Ramp  Time: 1 minute.
(iii) Ramp  Length: 4 minutes.
(iv) Ramp  Slope: 80.
SLA parameters:
(i) Service Capacity Contracted: 900 requests/minute.
(ii) Service Response Time: 15 seconds.
(iii) Requests Rejection Rate: 15%.
Service management parameters:
Service Capacity: Service Capacity Contracted (900 requests/minute).
