<DIV>Dear all,</DIV>
<DIV> </DIV>
<DIV>I got two questions about how to "translate" Gams-equations to
FlopC++-constraints.</DIV>
<DIV> </DIV>
<DIV>1)</DIV>
<DIV> </DIV>
<DIV>
<DIV>The problem is, that I don't know how to translate "$(DC(d,c) and DG(d,g))"
to "such_that" in this special case:</DIV>
<DIV> </DIV></DIV>
<DIV>GAMS:</DIV>
<DIV>...</DIV>
<DIV>Equations</DIV>
<DIV>AP_AlleEinplan(c,d,g)</DIV>
<DIV>...</DIV>
<DIV>AP_AlleEinplan(c,d,g)<U>$(DC(d,c) and DG(d,g))</U>.. sum(r,sum(t,
x(r,t,d,g)))=e=1;</DIV>
<DIV> </DIV>
<DIV>My idea about this:</DIV>
<DIV> </DIV>
<DIV>FlopC++:</DIV>
<DIV>...</DIV>
<DIV>MP_constraint<BR> AP_AlleEinplan(c,d,g)</DIV>
<DIV>...</DIV>
<DIV>AP_AlleEinplan(c,d,g) = <U>sum(d.such_that(DC(c,d)>-2),
sum(g.such_that(DG(d,g)>-2),</U> sum(r,sum(t, x(r,t,d,g)))))==1;<BR></DIV>
<DIV>2)</DIV>
<DIV> </DIV>
<DIV>The second problem is about "Alias" in a similar case as (1):</DIV>
<DIV> </DIV>
<DIV>GAMS:</DIV>
<DIV>...</DIV>
<DIV>Alias(d, dtilde)</DIV>
<DIV>Alias(g, gtilde)</DIV>
<DIV>...</DIV>
<DIV>Equations</DIV>
<DIV>AP_GruppenLink(c,l,g,<U>gtilde</U>,d,<U>dtilde</U>,r,t) </DIV>
<DIV>...</DIV>
<DIV>AP_GruppenLink(c,l,g,<U>gtilde</U>,d,<U>dtilde</U>,r,t).. x(r,t,d,g)=e=x(r,t+1,<U>dtilde</U>,<U>gtilde</U>);</DIV>
<DIV> </DIV>
<DIV>
<DIV>FlopC++:</DIV>
<DIV>...</DIV>
<DIV>MP_index dtilde, gtilde;</DIV>
<DIV>...</DIV>
<DIV>MP_constraint</DIV>
<DIV>AP_GruppenLink(c,l,g,<U>g(gtilde)</U>,d,<U>d(dtilde),</U>r,t) </DIV>
<DIV>...</DIV>
<DIV>AP_GruppenLink(c,l,g,<U>g(gtilde)</U>,d,<U>d(dtilde)</U>,r,t).. x(r,t,d,g)==x(r,t+1,<U>d(dtilde),g(gtilde)</U>);</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>Thank you in advance,</DIV>
