Simulation-based optimisation approach to improve emergency department resource planning: A case study of Tunisian hospital.

Background: The emergency department (ED) is a gateway to hospitals and is in the centre of hospital management efforts. It is often saturated by a continuous flow of patients, which causes excessive patient waiting time.

Aims: This study integrates simulations with optimisation to design planning decision support for an ED.

A pull-strategy for the appointment scheduling of surgical patients in a hospital-integrated facility.

This paper addresses the daily appointment scheduling (AS) of patients in a hospital-integrated facility where outpatients and inpatients are treated simultaneously and share critical resources. We propose a lean approach based on the pull-strategy "Constant Work in Process" (ConWIP) to develop robust and easy-to-implement AS rules. Our objective is to reduce patients' waiting time and maximise the use rate of resources while considering the global surgical process and stochastic service times.

Study by 1H NMR of the concentration of monomer-units on interface polymer grafted on silica using magic angle spinning and relaxation techniques.

The segmental motion of poly(ethylene oxide) grafted on silica has been investigated by 1H and 13C magnetic resonance. The local monomer units concentration on an interface is evaluated. Two independent techniques, namely magnetic relaxation and magic angle spinning, are used and give a good agreement for the physical parameters describing the monomer units concentration on the surface.
