I could not find my mistake. Please, help me
obj.. z=e=sum((i,j,s),FC(i,j,s)*Y(i,j,s))+sum((i,j,s),v(i,j,s)*P(i,j,s))+sum((i,s),cp(i,s)*CO(i,s))+sum((i,s,c),t(i,s,c)*supply(i,s,c))+sum((i,s),h(i,s)*inventory(i,s))+sum((i,s),ss(i,s)*I_D(i,s))+sum((i,c),m(i,c)*I_S(i,c))+sum((i,s),BC(i,s)*B(i,s))
**** $140
**** 140 Unknown symbol
There is a 140 error at the z part...
GAMS error 140
Re: GAMS error 140
The error says "unknow symbol", so you probably have not declared z. Errors often have something to do with context. So it really helps to send the entire model file if you expect help as spelled out in the forum rules: app.php/rules
