Abstract

In this paper, we address the distribution problem of liquefied petroleum gas (LPG). In particular we are targeting the optimization of pickup and split delivery of gas bottles to a set of customers with loading constraints. The problem combines the loading of a heterogeneous fleet of vehicles through set of different size racks and then the establishment of divisible deliveries (split delivery: SDVRP). The problem discussed in this paper can be presented as a Multi-depot Two-Loading Split Delivery and Pickup using Heterogeneous fleet of Vehicles with Time Windows vehicle Routing Problem and with Multi-Product (2L-SDP-HVRPTW-MP). After proposing a mathematical formulation for this problem (MILP), we tested our model firstly by a small instances using ILOG CPLEX solver following this by testing and discussing numerical results.
