Vehicle routing with roaming delivery locations
TL;DR: In this article, the authors propose the vehicle routing problem with roaming delivery locations (VRPRDL) to model an innovation in last-mile delivery where a customer's order is delivered to the trunk of his car.

The Dynamic Dispatch Waves Problem for same-day delivery
TL;DR: The computational results suggest that the best dynamic policy can reduce the average cost of an a priori policy by 9.1% and substantially improves the fraction of orders delivered (order coverage), demonstrating the importance of reactive optimization for dynamic SDD services.

Fitting piecewise linear continuous functions
TL;DR: This work considers the problem of fitting a continuous piecewise linear function to a finite set of data points, modeled as a mathematical program with convex objective, and introduces mixed-binary generalizations that allow variability in the regions defining the best-fit function’s domain.

The One-Dimensional Dynamic Dispatch Waves Problem
TL;DR: This work proposes an efficient dynamic programming approach for the deterministic variant of the dynamic dispatch waves problem, and uses it to design an optimal a priori policy with predetermined routes for the stochastic case.

Consolidation strategies for the delivery of perishable products
TL;DR: In this article, a look-ahead heuristic that takes advantage of economies of scale by aiming to ship larger quantities is proposed, and the results demonstrate that the heuristic provides solutions that are near the lower bound provided by the dynamic programming model.
