Analyzing High-Risk Emergency Areas with GIS and Neural Networks: The Case of Athens, Greece
(2014)Any analysis of health service problems facing the world today must consider that these problems exist in a geographic context. This fact has led to an increased need for accurate and current information to support emergency ... -
Backorder penalty cost coefficient "b": What could it be?
(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 ... -
A content-based publish/subscribe framework for large-scale content delivery
(2013)The publish/subscribe communication paradigm has become an important architectural style for designing distributed systems and has recently been considered one of the most promising future network architectures that solves ... -
Crime and the effectiveness of public order spending in Greece: Policy implications of some persistent findings
(2013)Increasing crime rates invariably result in calls for more police protection which requires the allocation of additional scarce resources to policing and public order. In an environment of fiscal pressures, the effectiveness ... -
Optimal control of flexible servers in two tandem queues with operating costs
(2008)We consider two-stage tandem queuing systems with dedicated servers in each station and flexible servers that can serve in both stations. We assume exponential service times, linear holding costs, and operating costs ... -
Optimal use of excess capacity in two interconnected queues
(2007)We consider a two-stage tandem queueing network where jobs from station 1 join station 2 with a certain probability. Each job incurs a linear holding cost, different for each station. Each station is attended by a dedicated ... -
Packet skipping and network coding for delay-sensitive network communication
(2012)We provide an analytical study of the impact of packet skipping and opportunistic network coding on the timely communication of messages through a single network element. In a first step, we consider a single-server queueing ...
