Dear Mr. Fleischer
I try to solve a specific project scheduling problem (Release
and Rehire (RRH) metric).
Models and problem data that acquired from CPM method send with email.
I solved my model (RRH) without any error, but I haven't the true solution, maybe in the constraint 1, I have an error and
do you know, can model 1 & RRH link together?
**********************************************************************************
co1:
forall(t in date, k in resources)
u[t,k] == sum(i in activities) res[i,k] * sum(t1 in date : bound1<=t1<=bound2) s[t1,i];
that :
x = The excess amount of resource k on day t when compared to the
targeted amount (Wk).
s(t,i) = 1 if activity i starts on day t; 0 otherwise.
qt,k = 1 if daily resource usage for resource type k on day t is greater than
usage on another day that is being compared to the usage on day t; 0
otherwise.
ut,k = Amount of resource k used on day t.
y(t,k) = shortage amount of resource k on day t when compared to the
targeted amount
umaxk = the maximum daily resource usage for resource type k.

Please, advise me and let me know, how can I fix my model?
