A Simulation Approach to Decision Making in IT Service Strategy
Table 1
Patterns of behavior of customer’s orders.
Orders tendency
Description
Const
After the launching of a special offer, the number of orders received experiments a rapid growth and it remains constant as its peak value. Requests Received Rate = Initial Value + PulseHeight * Pulse (PulseTime, Sim Period)
Ramp
The increment of the number of orders is not step-shaped but gradual; hence, it has been modeled as ramp. Requests Received Rate = Initial Value + Ramp (Ramp Slope, Ramp Time, Ramp Length)
Pulse
The growth that the number of orders stays as its peak value for a certain amount of time and then descends gradually. Requests Received Rate = Initial Value + PulseHeight * Pulse (PulseTime, PulseWidth)
