Thank you!
this is my new challenge…i don´t understand the error in this constrain, i have tried in different ways but nothing… (alpha is a constant like 1)
Constraint {sum{i in FARMS, j in FARMS: XS[i,j]} >= sum{i in FARMS,Alpha*Q[i]};}
thank you in advance
Oscar
this is the program just in case...
#%data biomass-data-Small.cdat : SIZE set
%data biomass-data-Small.cdat : FARMS set, SP, TC, PC, Q[FARMS], d[FARMS,FARMS], gamma[FARMS], CF, Alpha, K
variables:
#Quantity of waste treated at plant i
X[FARMS]: real[0..];
#Quantity of waste send from farm j to plant i
XS[FARMS,FARMS]: real[0..];
#1 if plant i is installed with capacity k
Y[FARMS]: binary;
#1 if we send waste from farm j to plant i
W[FARMS,FARMS]: real[0..];
objectives:
Profit: sum{i in FARMS: (SP-PC)* X[i] }
- sum{i in FARMS, j in FARMS : TC * XS[i,j] * d[i,j]}
- sum{i in FARMS : CF*Y[i] } ->max;
constraints:
# you cannot send more than farm´s capacity-
farms {j in FARMS: sum{i in FARMS: XS[i,j]} <= sum{i in FARMS:Q[j]*W[i,j]};}
#A farm can only send to one plant-
exclusivity {j in FARMS : sum{i in FARMS: W[i,j]} <= 1;}
#Maximum one plant per site-
nPlants {i in FARMS : Y[i] <= 1;}
#You can send to i only if there is a plant there-
cond1 {i in FARMS,j in FARMS: W[i,j] <= Y[i];}
#Production capacity-
#ProductionCap: X[] <= K*Y[];
ProductionCap {i in FARMS: X[i] <= K*Y[i];}
# Equivanlence between what is send (waste) and what is produce (methane)-
equivalence {i in FARMS: X[i] = sum{j in FARMS: gamma[i]*XS[i,j]};}
Constraint {sum{i in FARMS, j in FARMS: XS[i,j]} >= sum{i in FARMS,Alpha*Q[i]};}
