Advances in stochastic models of manufacturing and service operations
Tan, B.; Gershwin, S. B.; Liberopoulos, G.; Meerkov, S. M.; Papadopoulos, C. T. (2015)The special issue on advances in stochastic models of manufacturing and service operations presents state-of-the art research results in the area of stochastic models for the analysis, design, coordination, and control of ... -
An analytical method for the performance evaluation of echelon kanban control systems
Koukoumialos, S.; Liberopoulos, G. (2006)We develop a general purpose analytical approximation method for the performance evaluation of a multi-stage, serial, echelon kanban control system. The basic principle of the method is to decompose the original system ... -

Application of zonal pricing in Greece's electricity market
Andrianesis, P.; Liberopoulos, G.; Papalexopoulos, A. (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 ... -
Backorder penalty cost coefficient "b": What could it be?
Liberopoulos, G.; Tsikis, I.; Delikouras, S. (2010)The classical economic order quantity (EOQ) model with planned penalized backorders (PB) relies on postulating a value for the backorder penalty cost coefficient, b, which is supposed to reflect the intangible adverse ... -
Base stock versus WIP cap in single-stage make-to-stock production-inventory systems
Liberopoulos, G.; Dallery, Y. (2002)A single-stage production-inventory system produces parts in a make-to-stock mode, and unsatisfied demand is backordered. The system operates under a so-called base stock with WIP cap replenishment policy, which works as ... -
Comparative modelling of multi-stage production-inventory control policies with lot sizing
Liberopoulos, G.; Dallery, Y. (2003)We propose a unified modelling framework, based on a queuing network representation, for describing, comparing and contrasting classical and new multi-stage production-inventory control policies with lot sizing. The classical ... -

Energy-reserve markets with non-convexities: An empirical analysis
Andrianesis, P.; Liberopoulos, G.; Kozanidis, G. (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 ... -
Extended kanban control system: combining kanban and base stock
Dallery, Y.; Liberopoulos, G. (2000)This paper introduces a new mechanism for the coordination of multi-stage manufacturing systems. This mechanism is called the Extended Kanban Control System (EKCS) and depends on two parameters per stage, the number of ... -
Flight and Maintenance Planning of Military Aircraft for Maximum Fleet Availability
Kozanidis, G.; Liberopoulos, G.; Pitsilkas, C. (2010)Every aircraft, military or civilian, must be grounded for maintenance after it has completed a certain number of flight hours since its last maintenance check. Flight and maintenance planning (FMP) of military aircraft ... -
Foreword

Greek wholesale electricity market: Forthcoming market changes and bid/cost recovery
Andrianesis, P. E.; Liberopoulos, G.; Papalexopoulos, A. D. (2012)The Greek wholesale electricity market is based on a day-ahead unit commitment market clearing and generation dispatch formulation with co-optimization of energy and reserves without the participation of transmission. An ... -
Heuristics for flight and maintenance planning of mission aircraft
Kozanidis, G.; Gavranis, A.; Liberopoulos, G. (2014)Flight and Maintenance Planning (FMP) of mission aircraft addresses the question of which available aircraft to fly and for how long, and which grounded aircraft to perform maintenance operations on, in a group of aircraft ... -
The "hidden cost" of renewable energy sources in electricity pool markets
Andrianesis, P.; Liberopoulos, G. (2012)The aim of this paper is to explore the "hidden cost" associated with the uncertainty in power generation that Renewable Energy Sources (RES) introduce in electricity pool markets. This cost, which is additional to the ... -
Impact of emissions cost on the mid-term generation scheduling in the Greek Electricity Market
Andrianesis, P.; Liberopoulos, G.; Biskas, P. (2010)The EU Emissions Trading Scheme, Europe's main mechanism for implementing EU climate policy, is driving thermal electricity generation units to incorporate their emissions cost into their variable costs. In this paper, we ... -
The impact of wind generation on isolated power systems: The case of Cyprus
Andrianesis, P.; Liberopoulos, G.; Varnavas, C. (2013)In this paper, we explore the impact of wind generation on isolated power systems, using the system of Cyprus (an island) as a case study. Since 2010, Cyprus has been facing the challenge of integrating intermittent wind ... -

Medium-Term Unit Commitment in a pool market
Andrianesis, P.; Liberopoulos, G.; Biskas, P.; Bakirtzis, A. (2011)We consider a mandatory pool, based to the one established in the Greek electricity market, in which the unit commitment and the scheduling of energy and reserves are the solution of Day-Ahead Scheduling (DAS), an optimization ...
