Shelf Life Simulation

 

The following transform is used to generate time-activity data to evaluate the shelf life transform.

' SIMULATION FOR SHELF LIFE ANALYSIS
' INPUT
DT=3       ' TIME INCREMENT (MONTHS)
N=25       ' NUMBER OF DATA POINTS
B=-.1      ' SLOPE OF ACTIVITY LINE
STD=2      ' STD DEVIATION OF GAUSSIAN NOISE
RES=1      ' FIRST COLUMN OF OUTPUT
' PROGRAM
X=DATA(DT,N*DT,DT)
A=100
Y=A+B*X
YF=Y+GAUSSIAN(SIZE(X),0/0,0,STD)
' OUTPUT
COL(RES)=X
COL(RES+1)=ROUND(YF,2)
