Integrated Vehicle Routing Problems: A Survey

The progress in algorithmic design, combined with the technological advances, has encouraged researchers to study integrated problems, that is problems that jointly optimize two or more previously studied sub-problems. The solutions of integrated problems, that are computationally harder to solve, offer substantial advantages with respect to the sequential solutions of the sub-problems. This chapter has the goal to discuss the main classes of integrated problems that include a routing component, namely, the inventory routing problems, the location routing problems, routing problems with loading constraints, and two-echelon routing problems.
