How ReModel works

ReModel will run in 2 monthly cycles, with each cycle focusing on a different simulation model. Each cycle will consist of two sessions: a Running session and a Reusing session.

Session 1: Running - this session will be an opportunity to clone and run the model, reproduce an existing result or scenario, and confidently explore the model and its outputs. Participants will be encouraged to ask questions and share their insights.

Session 2: Reusing - this session will focus on the technical aspects of the model, including its structure, implementation, data requirements and input assumptions. Participants will consider what they would change, whether they understand the model well enough to make those changes, and how an edited model should be checked and documented.

Each session will last for 1 hour, and will follow a participative discussion format.

The sessions are free to attend, but spaces will be capped at 15 places per session on a first-come, first-served basis; NHS analysts will receive priority.

Register for ReModel

You can sign up for one, several or all ReModel cycles. Each cycle focuses on one open simulation model and includes two linked sessions: Running and Reusing. Registration for a cycle covers both sessions in that cycle.

Cycle 1: Non-Elective Flow Simulation

Cycle 1 focuses on the open-source Non-Elective Flow Simulation, a discrete-event simulation of patients moving from the emergency department into same-day emergency care or an inpatient bed. We will explore how bed capacity, length of stay and same-day emergency care activity affect queues and waiting times.

Registration for this cycle covers both online sessions and will open on 13 August 2026 and close on 2 October 2026:

  • Running the model: 7 October 2026
  • Reusing the model: 28 October 2026

Sign up for Cycle 1

Cycle 2: Meeting the demand of NHS 111 for primary care services

Cycle 2 focuses on MOOOD, an open-source discrete-event simulation that follows callers after an NHS 111 primary-care disposition and models their subsequent contact with primary care, NHS 111, ambulance services and emergency departments. We will explore how timely primary-care contact affects activity across services and potentially avoidable emergency department attendance.

Registration for this cycle covers both online sessions and will open on [insert date] and close on [insert date]:

  • Running the model: 25 November 2026
  • Reusing the model: 6 January 2027

Cycle 3: The Value of Triage during Periods of Intense COVID-19 Demand

Cycle 3 focuses on an open R simulation of intensive-care triage during periods of intense COVID-19 demand. We will explore how first-come, first-served admission, demand-based triage and reverse triage interact with demand, length of stay and capacity, and affect lives and life-years lost.

Registration for this cycle covers both online sessions and will open on [insert date] and close on [insert date]:

  • Running the model: 27 January 2027
  • Reusing the model: 24 February 2027
