BluSKY Elevator Simulation and Analysis (SimEYES)

This list captures both the standard capabilities of our elevator-traffic simulators and the cutting-edge extensionsneeded to model modern security workflows, smart-building integrations, and next-generation passenger experiences.

Core Simulation Features:​

  1. Up-Peak Analysis
  • Description: Models passenger traffic during the morning rush (mostly upward trips from the lobby).
  • How It’s Used: Simulate fixed intervals (e.g. 5 minute slices) with specified arrival rates and population; calculate handling capacity, average wait time, and car‐interval metrics.
  • Value: Determines the number and speed of cars needed, and optimal group sizes, to meet service‐level targets and minimize lobby congestion.
  1. Down-Peak & Two-Way Analysis
  • Description: Simulates end-of-day egress (down-peak) or mixed flows (e.g. lunch periods) with simultaneous up- and down-calls.
  • How It’s Used: Inject directional arrival patterns (e.g. 80 % exiting in 10 minutes) or balanced flows; evaluate waiting/travel times under different control strategies.
  • Value: Ensures elevator systems maintain acceptable performance across all daily traffic profiles, not just up-peak.
  1. RTT (Round-Trip Time) Calculations
  • Description: Computes the theoretical cycle time for a car to leave the lobby, serve calls, and return.
  • How It’s Used: Compare RTTs for different speeds or car counts in tall buildings (e.g. 30-story at 1.6 m/s vs 2.5 m/s).
