Feedback control of waiting times [PDF]

Physical Review E, 2016
Feedback loops are known as a versatile tool for controlling transport in small systems, which usually have large intrinsic fluctuations. Here we investigate the control of a temporal correlation function, the waiting time distribution, under active and passive feedback conditions.

ELIMINATING ENFORCED IDLENESS OF RESOURCES AND JOB WAITING TIME IN TIME CONSTRAINED CONSTRUCTION ACTIVITIES USING WAITING LINE THEORY

Journal of Construction Project Management and Innovation, 2015
Waiting of labour on construction site is a waste of energy and has been described as a shortcoming and production waste that can affect work performance and profitability of contractors.

Modelling Patients Waiting and Service Time by ARIMA Model: A Case of Federal University Gusau Clinic

Recent Advances in Natural Sciences, 2023
The ability to model and forecast waiting and service time to increase patients' satisfaction, reduce waiting time, avoid casualties, and increase efficiency in service delivery is crucial.

Waiting time prioritisation: Evidence from England [PDF]

Social Science & Medicine, 2016
A number of OECD countries have introduced waiting time prioritisation policies which give explicit priority to severely ill patients with high marginal disutility of waiting. There is however little empirical evidence on how patients are actually prioritised. We exploit a unique opportunity to investigate this issue using a large national dataset with

Fractional calculus and continuous-time finance II: the waiting-time distribution

, 2000
We complement the theory of tick-by-tick dynamics of financial markets based on a Continuous-Time Random Walk (CTRW) model recently proposed by Scalas et al., and we point out its consistency with the behaviour observed in the waiting-time distribution ...

Waiting time dynamics of priority-queue networks

, 2009
We study the dynamics of priority-queue networks, generalizations of the binary interacting priority queue model introduced by Oliveira and Vazquez [Physica A {\bf 388}, 187 (2009)].

Coupled continuous time random walks in finance [PDF]

, 2006
Continuous time random walks (CTRWs) are used in physics to model anomalous diffusion, by incorporating a random waiting time between particle jumps. In finance, the particle jumps are log-returns and the waiting times measure delay between transactions.

Improving outpatient satisfaction by extending expected waiting time

BMC Health Services Research, 2019
Background Long waiting times result in low satisfaction. Although several methods are used to shorten the actual waiting time (AWT) in large hospitals of China, the outpatients still have a long actual waiting time.

Optimized reduction of uncertainty in bursty human dynamics

, 2011
Human dynamics is known to be inhomogeneous and bursty but the detailed understanding of the role of human factors in bursty dynamics is still lacking.

Assessing the impact of a waiting time survey on reducing waiting times in urban primary care clinics in Cape Town, South Africa

Journal of Public Health in Africa, 2017
A waiting time survey (WTS) conducted in several clinics in Cape Town, South Africa provided recommendations on how to shorten waiting times (WT). A follow-up study was conducted to assess whether WT had reduced.
