We present a general framework for modeling routing problems based on formulating them as a traditional location problem called the Capacitated Concentrator Location Problem. We apply this framework to two classical routing problems: the Capacitated Vehicle Routing Problem and Inventory-Routing Problem. In the former case, the heuristic is proven to be asymptotically optimal for any distributio...

In this work, we address a production and inventory routing problem for liquid oxygen supply chain comprising facilities, distribution network, resources. The key decisions of the involve levels plants, delivery schedule through heterogeneous vehicles, strategies national stock-out prevention. Due to complexity, propose two-level hybrid solution approach that solves using both exact metaheurist...

This study extends a mathematical model that integrates the location, allocation, inventory replenishment and routing decisions simultaneously. To cope with inherent uncertainty of parameters, we implement a continuous-time Markov process and derive the performance measures of the system. Using the obtained results, the problem is formulated as a mixed integer nonlinear programing model (MINLP)...

In the strategic design of a distribution system, the right number of stock points for the various products is an important question. In the last decade, a strong trend in the consumer goods industry led to centralizing the inventory in a single echelon consisting of a few parallel warehouses or even a single distribution center for a Europe-wide distribution system. Centralizing inventory is j...
