Enhanced Substitution Model

Overview
The Enhanced Substitution Module (ESM) is an automated flight substitution aid for airline users. ESM is an optional add-on component to Flight Schedule Monitor (FSM). It provides resource alerts, delay previews, and other tools to assist a user in strategically canceling and substituting flights that are controlled by ATC regulations. ESM also includes algorithms for automating repetitive tasks and for evaluating complex priority scenarios to choose preferred swaps. Messaging functionality is supplied for communicating changes both to the Enhanced Traffic Management System (ETMS) and within an airline’s operation center.

Product Features
Flight substitution aid for airline users Add-on component to Flight Schedule Monitor Messaging functionality for communicating changes to ETMS and airline operation centers Reduces ATC delay for airline flights Analysis tool to reenact historical scenarios Prototype substitution procedures

Benefits
The primary benefit of ESM is reduction of ATC delay for an airline’s flights, which translates directly into cost savings for the carrier. Daily savings for a hub carrier at a single regulated airport can easily reach dozens of hours and many thousands of dollars. ESM is also used as an analysis tool to reenact historical scenarios to evaluate lessons learned and benefit future substitutions. The ESM platform has repeatedly been utilized to prototype new substitution procedures and been made available to all CDM participants (including non-ESM customers) for trial in human-in-the-loop tests, aiding rapid concept verification. Additionally, ESM is routinely supplied at the request of the Volpe National Transportation Systems Center for direct testing of the actual substitution processing logic in ETMS.

Deployment
ESM is Metron Aviation’s first commercial software product. The initial version went into prototype testing by several major US and Canadian airlines in January 2000 and quickly moved into operational use that Spring. The customer base has since grown to include over a dozen carriers of all sizes, comprising the vast majority of airlines doing substitutions. The original C++ software is being replaced by a new JAVA version with an updated architecture and tiered functionality to accommodate users with varying resources and requirements.
