Application of zonal pricing in Greece's electricity market
(2009)Greece's electricity market is divided in two zones, North and South, due to a generation-consumption system configuration that creates a significant transmission bottleneck from North to South. Clearly, a zonal pricing ... -
Assessing the impacts of energy storage on the electricity market-clearing algorithms
(2021)This work presents a generic optimization framework based on linear Mixed Integer Programming to assess energy storage options' influence on the operational scheduling and the economic performance of a given power system ... -
Assessing the Transition of the Romanian Power System
(2020)This work presents a generic mixed integer linear programming model to determine the optimal energy and reserves scheduling of a renewable-based multi-zonal power system. In particular, through a detailed unit commitment ... -
Benders decomposition with integer subproblem
(2017)The application of Benders decomposition method to a problem might result in a subproblem including integer variables. In this case, it is not able to apply the classical Benders algorithm. In this study we present a ... -
Bilevel programming solution algorithms for optimal price-bidding of energy producers in multi-period day-ahead electricity markets with non-convexities
(2021)We consider the problem of devising optimal price-offers (bids) for an energy producer participating in a multi-period day-ahead electricity market which exhibits non-convexities due to the discrete nature of the generation ... -
Branch and price for covering shipments in a logistic distribution network with a fleet of aircraft
(2018)We consider the problem of covering a set of shipments in a logistic distribution network with a fleet of aircraft. The aim is to cover as many shipments as possible, while also minimizing the number of aircraft utilized ... -
Column generation for scheduling shipments within a supply chain network with the minimum number of vehicles
(2014)We consider the problem of scheduling a set of shipments between different nodes of a supply chain network. Each shipment has a fixed departure time, as well as an origin and a destination node, which, combined, determine ... -
A dynamic integer programming approach for free flight air traffic management (ATM) scenario with 4D-trajectories and energy efficiency aspects
(2020)The growth in demand for air transport has generated new challenges for capacity and safety. In response, manufacturers develop new types of aircraft while airlines open new routes and adapt their fleet. This excessive ... -
Energy-reserve markets with non-convexities: An empirical analysis
(2009)In this paper, we address the design of a joint energy - reserve electricity market with non-convexities which are due to the fixed costs and capacity constraints of the generation units. Motivated by the relevant literature ... -
Generic approaches for the rescheduling of public transport services
(2020)The current paper discusses the problem of the synchronization of public transit services through the rescheduling of their initial execution times. The objective of the analysis is the minimization of waiting time that ... -
A heuristic approach for overlay content-caching network design in 5G wireless networks
(2016)With a wide variety of mobile applications and social networks, there is a growing demand for anytime, anywhere access to high quality video and other multimedia content. Fifth generation wireless networks are aiming to ... -
A hybrid approach to frequent itemset hiding
(2007)In this paper, we propose a novel, exact border-based approach that provides an optimal solution for the hiding of sensitive frequent itemsets by (i) minimally extending the original database by a synthetically generated ... -
An integer programming approach for frequent itemset hiding
(2006)The rapid growth of transactional data brought, soon enough, into attention the need of its further exploitation. In this paper, we investigate the problem of securing sensitive knowledge from being exposed in patterns ... -
Link scheduling for multiple multicast sessions in distributed wireless networks
(2013)In this letter we investigate link scheduling algorithms for throughput maximization in multicast wireless networks. According to our system model, each source node transmits to a multicast group that resides one hop away. ... -
Mixed integer biobjective quadratic programming for maximum-value minimum-variability fleet availability of a unit of mission aircraft
(2017)We consider the FMP problem encountered in the Hellenic Air Force (HAF), that is, the problem of issuing individual flight and maintenance plans for a group of aircraft comprising a unit, so as to maximize the fleet ... -
Mobile vehicle emission inspection service optimization: a flow intercepting location model and application
(2020)Emission screening and control for motorized traffic is mandatory in most countries worldwide. However, there may be cases that periodic inspections in permanent establishments may be inefficient and fail to enforce emission ... -
