Hello, I am trying to implement a single optimization vehicle platooning problem in the most straightforward way to approach a nonlinear integer program (INLP).  The result I got from the model doe...

Hello,I am solving a multi-objective model using the epsilon constrain method. but my code is not working. after using the epsilon method model become infeasible.  is that possible to use epsilon c...

Hello,I am trying to convert GAMS model to Gurobi. here I attached  more details below:I have already converted set parameters,variables and tables  power = ["Lignite", "Oil", "Gas", "RES"]load = [...

Hello,I looking for an example code for epsilon constrain in gurobi. I didn't find any code yet the definition of e-constraîn is if you want to consider the first objective function as the main obj...

I would like to generate multidict in Gurobi. inputs: from gurobipy import *number_of_vehicles = 2 vehicles_origin = [4, 6]vehicles_destination = [3, 0]total_time_vehicle = [35, 27] I would like to...

Hello developer,In my model, I need a constrain to ensure the truck leaves from starting node.I already ask almost the same question before with that solution I made some modifications. Now I got a...

Hello developer,I need to create a variable with truck, location, time. I use multidict() for my parameter. set_truck = ["trucks1","trucks2","trucks3"]location, cost, time= gp.multidict({("A", "B")...

Hello, This is just a continuation of the question How to model all truck  the same speed in a path? ensure is any trucks share the same road segment will make platoon (at the same time, same edge,...

Hello, Here I am trying to model a constrain that "ensure all truck Drive at the same speed throughout platoon". Here I have a set of parameters like location and set_speed location, set_speed= gp....

Hello, I'm new to Gurobi and not a really good programmer. I need to model a Multi-objective vehicle platooning problem. I created a mathematical model. I need to verify my model with Gurobi.After ...
