    One of the most well known variants of the (asymmetric) Traveling Salesman Problem (TSP) is the TSP with Pickup and Delivery (TSPPD). The problem is defined on a directed graph G = ( N , A ) with node set N = { 0 , 1 , ⋯ , n , n + 1 , ⋯ 2 n , 2 n + 1 } and arc set A = { ( i , j ) : i , j ∈ N } .Author: Enrico Malaguti, Silvano Martello, Alberto Santini

    A real life application is described. We compare this problem to the classic Travelling Salesman Problem. Based on their similarity we develop a simple heuristic consisting of pick-up and delivery along the travelling salesman tour. Asymptotic behavior and worst case analysis are provided.Author: Gur Mosheiov

    Jul 22, 2008 · The Traveling Salesman Problem with Pickup and Delivery (TSPPD) is defined on a graph containing pickup and delivery vertices between which there exists a one-to-one relationship. The problem consists of determining a minimum cost tour such that each pickup vertex is visited before its corresponding delivery vertex.Author: Irina Dumitrescu, Stefan Ropke, Jean-François Cordeau, Gilbert Laporte

    The PDTSPH is a generalization of two problems, as we will prove in Section 3, namely the pickup and delivery traveling salesman problem (PDTSP), and the pickup and delivery traveling salesman problem with LIFO loading (PDTSPL). The aim of the PDTSP is to find a vehicle route that fulfills all requests and minimizes transportation costs.Author: Marjolein Veenstra, Kees Jan Roodbergen, Iris F.A. Vis, Leandro C.

    In other words, for the Traveling Salesman Problem with Pickups, Deliveries and Draft Limits (TSPPDD) it must also hold that (v) when traveling along arc p i, jq, the total load of the ship cannot exceed minp li,ljq. We assume in the following, without loss of generality, that demands, ship capacity, and drafts are positive integers.

    This work addresses a more complex problem called the Probabilistic Pickup-and-Delivery Travelling Salesman Problem (PPDTSP). It is an extension of the PTSP where the route must start and finish at the depot and the other locations are grouped in pickup-delivery pairs.Author: Enrique Benavent, Mercedes Landete, Juan-José Salazar-González, Gregorio Tirado

    Abstract The Traveling Salesman Problem with Pickup and Delivery (TSPPD) describes the problem of nding a minimum cost path in which pickups precede their associated deliveries. The TSPPD is particularly im-portant in the growing eld of Dynamic Pickup and Delivery Problems (DPDP). These include the many-to-many Dial-A-Ride Problems (DARP) of companies such as Uber and Lyft, and meal delivery …
