Hi,

I am trying to setup a constant of type float, which is defined by the product of two other float constants. For Example:

int m = ...; // number of maintenance task (m=4)

{int} M = asSet(0..m); // All maintenance tasks

int s = ...; // number of shifts (s =1)

{int} S = asSet(1..s); // all shifts in the planning period

 

float Tmt[M][S] = ...; //Duration of task m in M in hrs

float Ctmt[M][S] = ...; // costs per hr downtime of maintenance task M

float Clp[M][S] = Tmt[M][S] * Ctmt[M][S]; // the total costs maintenance task M

I get the error Tmt was not expected and / or operator * does not exist for float float

I attached data and model file.

Thank you for any help,

Gustav

Hi,

in the .mod I would rather write

float Clp[m in M][s in S] =  Tmt[m][s] * Ctmt[s][s];

and in the .dat

Tmt = [[1], [7], [12], [10], [1]];
Ctmt = [[50],[200],[200],[200],[50]];

regards
