This paper will describe and review in-depth the impediments in implementing and developing dry ports, from a heuristic point of view. The dry port concept is based on the idea of a seaport directly connected by rail to inland intermodal terminals, where shippers can leave and/or collect their...

An algorithm is given for computing the serial correlations of the waiting time, and of the time in system, for successive customers in a GI/G/1 queue. The method depends on representing the inter-arrival time distribution in terms of a process in class K<sub>r</sub> (i.e., distributions with a rational...

We consider a setting of dual practice, where a physician offers free public treatment and, if allowed, a private treatment for which patients have to pay out of pocket. Private treatment is superior in terms of health outcomes but more costly and time intensive. For the latter reason it...

We analyze waiting times for price changes in a foreign currency exchange rate. Recent empirical studies of high-frequency financial data support that trades in financial markets do not follow a Poisson process and the waiting times between trades are not exponentially distributed. Here we show...

This paper analyzes the impact of type of insurance, income, and reason for appointment on waiting time for an appointment and waiting time in the physician's practice in the outpatient sector. Data were obtained from a German patient survey conducted between 2007 and 2009. We differentiated...

Long waiting lines are a common feature and a major concern in many public health care delivery systems. The waiting lines are often characterized as inefficient, because they are a burden to patients without generating any gains for providers. There is an ongoing debate in Germany regarding the...

This paper studies the impact of hospital competition on waiting times. We use a Salop-type model, with hospitals that differ in (geographical) location and, potentially, waiting time, and two types of patients; high-benefit patients who choose between neighbouring hospitals (competitive...

This paper analyses the effects of immigration on waiting times in the National Health Service (NHS) in England. Linking administrative records from the Hospital Episode Statistics (2003-2012) with immigration data drawn from the UK Labour Force Survey, we find that immigration reduced waiting...

A model of the Lu–Hamilton kind is applied to the study of critical behavior of the magnetized solar atmosphere. The main novelty is that its driving is done via sources undergoing a diffusion. This mimics the effect of a virtual turbulent substrate forcing the system. The system exhibits...

Using a recently proposed model Physica A 332 (2004) 566 of information transport on complex networks we study the role of network substrates on the statistics of queuing times and correlations in traffic streams. When navigation with an enlarged information horizon is applied the waiting time...
