WebNov 19, 2024 · Idea behind the formulation. The Miller-Tucker-Zemlin (MTZ) formulation uses an extra variable. The variable is called u i and gets a value for each node, except for the depot. If a vehicle drives from node i to node j, the value of u j has to be bigger than the value of u i. So each time a new node is being visited, the value for u i increases.
