ASGsim

In development

Empowering Airlines to Make Better Decisions. Built by Airline People for Airline People.

How will your schedule actually perform on the day, before you publish it?

ASGsim is a schedule resilience simulator. It runs a planned schedule through thousands of simulated operating days in which weather, air traffic control restrictions, aircraft technical issues, crew availability and gate constraints occur with realistic frequency and severity, and reports how the schedule performs.

What ASGsim is used for

01Schedule variants

Compare schedule variants before publication on on-time performance by station and bank, delay propagation through aircraft rotations, cancellations and missed connections.

02Buffers and targets

Set achievable on-time targets and size ground time, block time and spare aircraft against what the simulation shows they buy.

03Recovery strategies

Evaluate swap rules, hub-protection policies and the recovery time after a major disruption.

04Cost of reliability

Combined with ASGcostIQ, every simulated outcome becomes a cost, so trade-offs between utilization and reliability become financial decisions.

Designed by airline people for airline people, ASGsim focuses on what matters most:

Efficiency

Minimal setup: a planned schedule in, a statistical picture of its performance out.

Reliability

Disruptions occur with realistic frequency and severity, calibrated to the airline's own operating statistics.

Speed

Thousands of operating days simulated per run, so a schedule variant is assessed in one pass.

Flexibility

Used in schedule build, operations planning, irregular-operations reviews and the design of operational control policies.

How a schedule is stress-tested

01
The schedule
The planned schedule, with its rotations, ground times and block times.
02
Disruptions
Weather, air traffic control restrictions, aircraft technical issues, crew availability and gate constraints, drawn with realistic frequency and severity.
03
Operating days
Thousands of simulated days, each a different draw.
04
What is measured
On-time performance by station and bank, delay propagation, cancellations, missed connections and recovery time.
05
The comparison
Variants side by side; with ASGcostIQ, every outcome as a cost.
