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)
