Probabilistic Scheduling
Monte Carlo Critical Path
Rather than a single deterministic critical path, SpaceLean runs 1,000 schedule simulations on every save. Each task gets a criticality probability, zone congestion penalty, and crew bottleneck score — surfacing future critical tasks days before traditional CPM would.
1,000 Monte Carlo simulations on every schedule save
Criticality probability per task — not just binary critical/not
Zone congestion and penetration penalties baked in to each run
Crew bottleneck scoring detects resource-driven slippage early
Network centrality via Neo4j identifies structural risk nodes
