Set the Earned Value (EV) accrue value for a simulation run.

The EV accrued during the simulated project progress can be in line with the PV curve of the baseline schedule, or not. Since the PV is assumed to increase linearly along the activity duration, the EV can also increase in a linear fashion. However, a slower or quicker accrue also belongs to the possibilities:. 

  • Linear accrue: refers to an accrue which is similar to the PV accrue in the baseline schedule. The activity may be longer or shorter than its baseline version, but the EV accrue follows a similar linear pattern than its baseline version.
  • Concave or convex: The EV is accrued faster (concave) of slower (convex) than originally planned, denoting that resources are allocated earlier or later to the activity than originally planned.

This function required two parameters, as follows: 

  • Percentage accrue: percentage of activities with a nonlinear EV accrue (remaining fraction follows a linear EV accrue similar to the PV accrue).
  • Maximum accrue: This value determines the maximum value of the nonlinear accrue activities, between 0% (linear) or 100% (maximum convexity or concavity).
