Mismanagement of routing and deliveries between sites of the same company or toward external sites leads to consequences in the cost of transport. When shipping alternatives exist, the selection of the appropriate shipping alternative (mode) for each shipment may result in significant cost savings. In this paper, the authors examine a class of vehicle routing in which a fixed internal fleet is ...

Title of Dissertation / Thesis: PERFORMANCE AND ANALYSIS OF SPOT TRUCK-LOAD PROCUREMENT MARKETS USING SEQUENTIAL AUCTIONS Miguel Andres Figliozzi, Ph.D., 2004 Dissertation / Thesis Directed By: Professor Hani Mahmassani, Civil and Environmental Engineering Department Competition in a transportation marketplace is studied under different supply/demand conditions, auction formats, and carriers’ b...

Although air transport contributes to globalization, airline emissions have attracted focus in green logistics. In this work, we investigate the airline-fleet assignment problem from a risk-averse perspective which uncertain demand and fuel price are considered simultaneously. The objective is maximise total profit fashion, i.e., weighted sum of expected conditional value at risk profit. An app...

The airline industry has been a pioneer in using operations research techniques to solve complex business problems related to the schedule planning of the airline. Given a flight schedule, an airline’s schedule planning group needs to decide the itinerary of each aircraft and each crewmember so that the total revenue minus the total operating costs is maximum and all the operational constraints...

<span lang="EN-US">Airline fleet assignment is the process of allocating different types aircraft to scheduled flight legs in order reduce operating costs and increase revenue. In this research, flights data records from Egypt Air airlines was employed build an intelligent model predict optimal type for new flights. Deep neural network (DNN) support vector machines (SVM) used formulations...

This paper introduces a new type of constraints, related to schedule synchronization, in the problem formulation of aircraft ̄eet assignment and routing problems and it proposes an optimal solution approach. This approach is based on Dantzig±Wolfe decomposition/column generation. The resulting master problem consists of ̄ight covering constraints, as in usual applications, and of schedule synch...

High profitability and high costs have stiffened competition in the airline industry. The main purpose of study is to propose a computationally efficient algorithm for integrated fleet assignments aircraft routing problems real-case hub spoke planning problem. economic concerns operations led need minimising increasing ability meet rising demands. Since fleets are most limited valuable assets c...

Abstract This paper presents the development of a model how to assign LNG carriers from single source number scattered small-scale power plants in milk-run operation strategy. Typically, researchers assume that ports/terminals be visited are as given parameters. In this paper, specifications (infrastructures) considered consequence selected carriers. The objective is determine optimum size and ...
