From uncertain factors to possible outcomes

Follow one synthetic batch through the model. Select a factor to trace its connections.

Unobserved operating factorsRecorded outcomesAssumed model links
Bayesian operating-factor networkCoordination, scheduling, patient readiness, and anesthesia readiness connect to non-cancellation and timely starts. Anesthesia and the OR team connect to timely ends; all five factors connect to efficiency. Timely-start probability also connects to timely-end probability. These are assumed statistical links, not proven causes.

Possible outcomes

Dots: model means. Lines: central 90% ranges of modeled probabilities or expected efficiency, not intervals for observed results.

A distribution preserves the range of possible operating conditions.

Mock example only. No hospital data, fitted parameters, or original model inputs are shown. The network links are reconstructed from the project code; all numerical values are synthetic. Arrows represent model assumptions, not demonstrated intervention effects.

How this demonstration is calculated

Five independent beta priors generate 12,000 candidate factor sets. Fixed illustrative logistic coefficients connect them to three session-level binary outcomes and expected efficiency. A synthetic batch of 20 sessions supplies binomial likelihoods and a normal likelihood for mean efficiency. Importance weights approximate the joint posterior. The animation draws whole factor sets from that posterior, preserving the dependence introduced by conditioning on shared outcomes.

The original implementation used PyMC and MCMC to estimate uncertain factors, weights, and intercepts. This small demonstration fixes the coefficients and omits room, weekday, and staffing effects. The start-to-end link uses predicted start probability, as in the project code. It illustrates the mechanics, not the original model's fit or hospital performance.
