\(F_{i,t,b}=C_{i,t,b}+X_{i,t,b}\le G_{i,t,b}\)
7. Perished units should be less than 1% of all the collected units:
\(Y_{i,t,b}\le0.01\times X_{i,t,b}\)
4.4 The objective function
The objective function is designed to minimize cost, wasted units, and to keep inventory level from exceeding demand:
\(Z=\ Q\ \sum_i^8\sum_t^5\sum_b^7Y_{i,t,b}+L\ \sum_i^8\sum_t^5\sum_b^7X_{i,t,b}\ +\ \sum_i^8\sum_t^5\sum_b^7C_{i,t,b}\)
