Physician agents interacting with delegate agents for emergency department assessment diagnosis and treatment. From BMC paper May 2013, combining figs 1 and 2

Rich picture version of published simple model representation described as a capacitated processing model, modified to separate Patient Flow from workflow.

Dynamics of Emergency Room Crowding with treatment spaces and boarders waiting for ward beds (access block if the wait is too long).

Dynamics of Emergency Room Crowding with treatment spaces. Here we investigate the effect of constrained spaces and ignore any changes in treatment time or staffing effects. Many of the consequences occur before treatment with potential arrivals being turned away and arrivals leaving without being treated.

A work in progress based on GF

Dynamics of Emergency Department Crowding Initial Simplest Simulation of the View from the waiting room. Start of a simple introductory series which proceeds to IM-338  A simple CLD is at IM-340

Simulation model version of IM-398 CLD (which lists the reference).The dynamics of emergency and elective admissions competing for vacant ward beds in a hospital. Here Bed Capacity is a fixed parameter.  For discharge dynamics see IM-14124. For an adjusted bed capacity stock see IM-14144.For backlog and services see IM-8382

Simplest ED Model for Daily ED Performance with 1 ED area rather than 2 in IM-10571. Currently runs over a weekend and calibrated roughly to Weekend Data.Ward net discharges are extended in IM-12414. This insight IM-11936 is the Master Version with the story added. The previous running model, now without a story, is at IM-11079
