Future Electronics Model
Posted: Fri Jan 01, 2021 4:15 am
Hi,
I try to use vensim to re-build the model of Future Electronics which was in dynamo under the textbook by Michael goodman Study notes in SD.
But, I face several problems.
a. 2 units errors discovered - I cannot figure out what is wrong as I follow the unit mentioned in the text.
b. the effective Testers become negative - seems something missing. In the text , it does not mention any initial stock qty about the testers.
c. I cannot understand why hiring rate (HR.KL) would have the initial seting as the text mentioned below
HR.KL=(FHM.K)(TT.K+T,K) 1,R
HR=20/69 1.1,N
HR - HIRING RATE (MEN/MONTH)
FHM - FRACTION HIRED PER MONTH (FRACTION/MONTH)
TT - TESTERS IN TRAINING (MEN)
T - TESTERS (MEN)
it is very enjoying and rewarding tasks to rebuild the classic dynamo models in vensim. hope i can get advise to help.
Thank you
