Hi Dogancan

You had forgotten to add z =E= in the objective constraint and defined the model over all constraints, but hadnâ€™t defined the equation objs2 (I commented it out).

Cheers

Renger

equations

obj objective value

*obj2 obj2s

const1 bir rota kesin kullanÃ½lacak

const2(i)

const3(i)

const4(i)

;

obj… z =e= sum (j$(firstexit(j)),x(‘1’,j)*d(‘1’,j)*(f+(m/s))) ;

*((f+(a(i,j)/s))*a(i,j)*x(i,j)+(f+(e(j,q)/s))*e(j,q)*n(j,q)+(f+(r(q,z)/s))*r(q,z)*g(q,z)+(f+(o(z,v)/s))*o(z,v)*r(z,v)+

const1 … sum(j$(firstexit(j)),x(‘1’,j)) =e= 1;

const2(i)$(firstexit(i))… sum(j$second(j),x(i,j)) =e= x(‘1’,i);

const3(i)$(second(i))… sum(j$secondexit(j),x(i,j)) =e= sum(j$(firstexit(j)),x(j,i));

const4(i)(secondexit(i)).. x(i,'10') =e= sum(j(second(j)),x(j,i));

model cargoroute /all/;

solve cargoroute minimizing z using MIP ;
