Hello Jaromił, Thank you so much for your help and referances.all referances you mention are not free so I need to find another way find that referances. I have one more question about the lower an...

Hello Jaromił,TA[i,h] = arrival time of truck at node i. That is calculate  model.addConstrs(TA[origin[h],h] == 0 for h in truck)model.addConstrs(TD[origin[h],h] == 0 for h in truck) for j in nodel...

Hello  Mario, sorry for adding many questions. finally, I build a model for a time violation. \(TA_i^h\) = arrival time of truck at node i \(TD_i^h\) = departure time of truck at node i  \( TA_{o^h...

Hello Mario,Yes upper bound on the size of a platoon <= 5 not all trucks make platoons.  based on this model if trucks have large distance differences in the shortest path and travelling distance (...

hello mario,thank you for your reply. and I am so happy that you understand my model. I need to extend my model to minimize total time violations. first I need to find platoon edges. ie if any truc...

hello Mario,I understand what you mean. currently, I have a mathematical model for a single objective vehicle platooning problem (minimize fuel cost). c(e) = distance  between edges i,jThank youJo...

Hello Mario, Thank you for your reply. I have already explained my Vehicle platooning problem model in my previous question.  I just want to create a second objective to my model called minimizing ...

Hello, Thank you so much for your code that so helps full. your code is almost right for my model. 1.  is that possible to a /[ gp.max_() \] in the objective function. on your first answer, you use...

Hello Maliheh,Thank you for your answer.  I already have a model for the vehicle platoon problems with the objective minimize fuel cost. my task is to add a second objective to my model called mini...

Hi Maliheh,After so much reading and a lot of tries, I thought of covert this constrain to the objective function. Currently, I have 2 objectives for my model I need to use the epsilon constrain me...
