dc.description.abstract | This thesis shows the case of vehicle routing problem having the cross-dock system in
delivering products that consider the freshness-life. These products must be delivered in
full quantity before the time required for the customer's expectation of freshness. With the
aim of proposing a sustainable service, this paper considers the environmental aspects of
greenhouse gas emissions from petroleum outgoing vehicles. A Mixed Integer Linear
Programming (MILP) formulation is set up to solve the vehicle routing with cross-dock in
the view of minimizing the total costs while ensuring the efficient delivery of perishable
products. Finally, encoding the problem with the help of a Genetic algorithm (GA) and
comparing the result-based with the MILP to validate the model formulation that
contributes to the progress of the large-sized problem in the future. The result is a route for
each outgoing vehicle and the optimal schedule for vehicles corresponding to the receiving
and shipping dock door of the cross-dock. A sensitivity analysis of the model is also
performed, with changes to the elements of freshness life. | en_US |
