The Emergency Vehicle Routing Problem with Uncertain Demand under Sustainability Environments
The reasonable utilization of limited resources is critical to realize the sustainable developments. In the initial 72-h crucial rescue period after the disaster, emergency supplies have always been insufficient and the demands in the affected area have always been uncertain. In order to improve timeliness, utilization and sustainability of emergency service, the allocation of the emergency sup...
متن کاملThe Vehicle Routing Problem with Demand Range
We propose and formulate the vehicle routing problem with demand range (VRPDR), a new variation on the traditional vehicle routing problem. In the VRPDR, the delivery quantity for each customer i is allowed to vary from its original size di by an amount αdi where 0 ≤ α < 1. In adding this limited flexibility to the problem, there is potential to generate significant savings in the total distanc...
متن کاملThe Robust Capacitated Vehicle Routing Problem Under Demand Uncertainty
We study the robust capacitated vehicle routing problem (CVRP) under demand uncertainty, which determines a minimum cost delivery of a product to geographically dispersed customers using capacity-constrained vehicles. Contrary to the deterministic CVRP, which postulates that the customer demands for the product are deterministic and known, the robust CVRP models the customer demands as random v...
متن کاملA Vehicle Routing Problem with Inventory in a Hybrid Uncertain Environment
Manufacturers, who re-supply a large number of customers, continually struggle with the question of how to formulate a replenishment strategy. The purpose of this paper is to determine the optimal set of routes for a group of vehicles in the transportation network under defined constraints – which is known as the Vehicle Routing Problem (VRP) – delivering new items, and resolving the invent...
متن کامل1 Autonomous Decision Model Adaptation and the Vehicle Routing Problem with Time Windows and Uncertain Demand
A prerequisite for the application of computerized methods to tackle logistics decision problems is the representation of the current decision situation in a formalized fashion, a so-called decision model, normally described in terms of mathematical expressions (Williams 1999). Such a model, often of optimisation type, is than tackled by, typically heuristic, algorithms (Ibaraki et al. 2005; Mi...
