Using strong formulation for inventory routing

What is it about?

Strong formulations in mixed integer programming are usually helpful to solve larger size programs. This paper presents the computational advantages of using a strong formulation for a complex logistics problem.

Why is it important?

A simple adjustment on a mathematical model of the problem decreases the solution time in a complex solution procedure. Our results show that good upper/lower bounding is beneficial for the enumeration based solution procedures.
