This study aims to determine the battery electric bus service and charging strategy minimize total operational cost of transit system, where incurred by degradation non-linear profile is taken into account. We formulate a set partitioning model for this problem, subject predefined trip schedule limited facilities. A tailored branch-and-price approach then proposed find global optimal solution. ...

The VIPAFLEET project consists in developing models and algorithms for managing a fleet of Individual Public Autonomous Vehicles (VIPA). Hereby, we consider a fleet of cars distributed at specified stations in an industrial area to supply internal transportation, where the cars can be used in different modes of circulation (tram mode, elevator mode, taxi mode). One goal is to develop and implem...

The choice of roll stabilization system is critical for many types of ships. For warships where operational activities are fast and the concept of time is very effective, determining the most appropriate of these systems is of particular importance. Some operations, such as the landing of the helicopter on board, are critical for naval ships. Unwanted rolling motion makes this difficult. In add...

Abstract This study proposes a method for determining decision-making rules on fleet composition that are effective from perspective of profitability in the shipping industry, where there several market uncertainties such as fuel prices, freight rates, exchange rate, transportation demand, world capacity, and ship price. A simulator is used to calculate revenue based scenario. Using this optimi...

Virtual reality and 3D modeling techniques are increasingly popular modes of representation for historical artifacts cultural heritage, as they allow a more immersive experience. This article describes the process that was adopted development virtual application four ships involved in historic battle Navarino. The specific naval culmination military operations during Greek Revolution 1827, whic...

In this paper, we study the Transportation Fleet Maintenance Scheduling Problem (TFMSP) for a Logistic Service Provider (LSP) with many sub-companies (or branches). In the literature, Goyal and Gunasekaran’s [S.K. Goyal, A. Gunasekaran, determining economic maintenance frequency of a transportation fleet, International Journal of Systems Science 23 (4) (1992) 655–659] presented a mathematical m...

Intelligent electricity grids, or ‘Smart Grids’, are being introduced at a rapid pace. Smart grids allow the management of new distributed power generators such as solar panels and wind turbines, and innovative power consumers such as plug-in hybrid vehicles. One challenge in Smart Grids is to fulfill consumer demands while avoiding infrastructure overloads. Another challenge is to reduce imbal...

We develop algorithms for a single machine stochastic appointment sequencing and scheduling problem with waiting time, idle time, and overtime costs. This is a basic stochastic scheduling problem that has been studied in various forms by several previous authors. Applications for this problem cited previously include scheduling of surgeries in an operating room (Denton, 2007, Denton and Gupta,2...
