Re: [Help-glpk] operating following / has invalid

[Xypron]

Hello Asma,

R = (C1 + C3 * V1) / 1- (V2 * C2 )
is linear in R, V1, V2.

The model below is solved by glpsol.

Best regards

Xypron

param C1 := 1;
param C2 := 2;
param C3 := 3;

var R,  >= 0;
var V1, >= 0;
var V2, >= 0;

minimize obj : V1 + V2 + R;
s.t. c1: R = (C1 + C3 * V1) / 1- (V2 * C2);
end;

Hello,

 

I have this error: operating following / has invalid

 

The general form of my constraint it seems to: R = (C1 + C3 * V1) / 1- (V2 * C2 )

where C1 , C2 and C3 are constants with C2 and C3 > 0.

R and V1 is an reel variable.

V2 is an binary variable.

 

Are there some solution to express this constraint ? (lenearize this constraint) 

Best regards,

Asma
