Time Restriction

Question

Hello Members,

i want to add a time restriction constraint in my model in which i have variable s(i,j,k) for time where i and j belongs to node and k belongs to vehicle.

i want to add a constraint which will ensure that each vehicle will not work more than 8 hours.

Provide the possible formulation against this constraint.

Looking forward for response.

Hi Muhammad,

If I understand your question correctly, I think you should add a constraint called something like

LimitTime(k)

with definition

sum((i, j), s(i, j, k)) <= 8;

In English, this states that for every vehicle k, the total sum of its time s, as distributed over the (i, j) pairs, should be 8 or less.

I hope this helps!

Regards,

Mischa
