Optimizing combined tours: The truck-and-cargo-bike case

Schiewe, Philine; Stinzendörfer, Moritz - In: OR Spectrum 46 (2024) 2, pp. 545-587

In this paper, we introduce a last-mile delivery concept that is well suited for urban areas. By jointly optimizing the tour of a truck and a cargo bike, we ensure that each vehicle is used optimally. Here, we assume that the bike is restocked by meeting up with the truck so that no dedicated...
