Hello I need to create multidict variable that stores the arrival time of the truck in each node. I expect values to store in a variable format something like this. TA = {(node,truck): time} To fin...

Hello I have a mathematical model to minimize time violations. could you help me to Gurobi model. \(P_ij^(k,w)\) = Binary variable=1, if truck k and w drive as a platoon on edge \(e_ij\)\(ST^k\) = ...

Hello,this is a continuation of my previous question. I want to create an objective function of time window violation for the vehicle platoon problems.  edges = [(1, 3, {'weight': 1}),(3, 1, {'weig...

Hello,I would like to create an objective for time window violation. I already asked this question before for example as a simple model:I have a graph with 6 nodes with 2 trucks  edges = [(1, 3, {'...

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...
