Crisis Contagion Network Simulator

Response Action

Pick an action, then click a department node in the 3D graph to spend Response Points on it. Contain cuts current severity, Communicate restores Public Trust, Reinforce raises long-term resistance.

How it works

Six departments form a weighted dependency graph. An incident starts inside Operations and spreads to neighbouring units through a network-diffusion model, the same family of equations used for epidemic spread on a graph:

dS_i/dt = spread · Σ_j W_ij · S_j · (1 − S_i) · (1 − R_i)
          − decay · S_i − C_i(t) · S_i

S_i  = severity of node i, in [0,1]
W_ij = dependency weight between i and j
R_i  = permanent resistance from Reinforce (caps at 0.6)
C_i  = temporary containment rate from Contain, decays ~e^(−t/4s)

Public Trust falls in proportion to the current Crisis Index (the RP-weighted mean severity across all six nodes) and is restored by Communicate actions:

dTrust/dt = −k · CrisisIndex/100
Communicate: Trust += 8 (capped at 100), instant

Contain — immediately cuts a node's severity and adds a fading containment rate that suppresses regrowth for a few seconds.
Communicate — restores Public Trust directly; does not touch severity.
Reinforce — permanently raises a node's resistance term R_i, throttling how much of its neighbours' severity can flow in.
Response Points regenerate over time and are spent per action (Contain 6, Communicate 5, Reinforce 8) — the core trade-off is which node to treat before the graph's coupling lets the incident spread further.

This mirrors real incident-command practice: a crisis in one function (an outage, a breach, a recall) propagates through the units it depends on, and a manager with finite attention and budget must triage which nodes to contain, which stakeholders to communicate with, and which parts of the organisation to harden first.
