TAAM Releases - V2.0
2.0 – September 26. Released on schedule. Changes include:

• • • • •

Changes to date (1)

Improved documentation

• •

Beginners Guide updated, and

Reference Manual updated (26 pages of alterations, 162 pages with new content).

New implementation approach is more productive (iterative – develop/test 6 times for v2.0)

• • •
7

Development errors found and corrected early,
Design and Functional issues found and addressed early, and Clear assessment points for development.

Changes to date (2)

Improved testing of Simulation model:
DFS provided Preston with a current TAAM project (it included vectoring areas and other v1.3.x constructs) Preston staff reviewed project and looked for errors iteratively. Primarily Terminations and sequencing violations. These errors generated two actions:

• Identify software solution for the problem, and • Identify metric for the error in existing test projects.
Next steps:

• Remove false negative errors from our tests, • Define more metrics for the automated tests, and • Ensure the outstanding issues detected by the testing are resolved

Changes to date (3)

Creation of three separate teams for the development cycle: Product Management, Development, and System Test.

• • •

Product Management sets standards and expectations, Development works to meet these, and System Test verifies conformance.

TAAM Releases - V2.1

Beta: January 9th 2004, Final February 2004

The focus of this release is to clear the decks of remaining high profile issues. Key goals are:

•

Correction to the way aircraft fly SIDs and the resultant timemark errors,

• • • •
11

Completion of the Holding Stack implementation,
Reporter data load improvements, Simulation runtime improvements, and

Wind Prototype (propose to use GRIB format like AADS)

TAAM Releases - V2.1(cont)

Supported OS Solaris 2.8 and 2.9 RedHat 8.0 and 9.0 Licensing Changes. To support Solaris 9 we will have to update the version of FlexLM (CRO) This will not be backwards compatible so we will re-release v1.3.2 and v2.0 simultaneous with the v2.1Final.

TAAM Releases - V2.2

June 2004 The contents of this release are not finalised. Primary goals are:

• • •
•

Ground movement lineup queue behavior and runway exit,
the implementation of Planning Controller, and Gate and Taxi reports.

Other 2004 activities.
Supported OS has not been determined yet. Current intention is to drop RedHat standard and move to Redhat Enterprise. No change for Solaris.

•
13

Practical Guide update.

RedHat Enterprise
Issue: Preston spends significantly more time maintaining the Linux branch than the Solaris branch. Two issues:

• •

Frequent Linux release cycle requires multiple versions for each TAAM release, with associated Sys Admin costs, and Short release notice means ‘routine’ issues are delayed to the end of a project.

Undoubtedly the short release cycle is forcing customers to repeatedly upgrade. Proposal is to move to Redhat Enterprise Solutions.Effects will be:

• •
14

12-18 month release cycle, eliminating above problems, and Price neutral for everyone (~$1000-$2000 AU p.a.).

Software Knowledge Audit

The goal is to better understand the state of the TAAM source code. Preliminary results:

•
•

Lack clear requirements for behaviour/interaction of:Airspace Rules, Intrail functionality, and Conflict Resolution,
Code is well structured, with clear separation of engine from model from I/O and GUI. Potential for more code re-use between the modules (SIM and IDIS). Code re-use within the SIM module is good.

•
• •
15

Next steps: Complete the audit (consider the test coverage.), and Determine effort required to complete requirements documentation.

Rewrite/Evolve?

There has been repeated debate regarding the rewrite/evolve question. My conclusion is to evolve. Reasons are:

• • •
•

Proven ability to deliver, Implementation issues regarding code quality are addressed. Utilizes past investment – rewrite always seems to forget lessons learnt. Current team is well placed to evolve the product.

New Development

I currently understand the following issues to be a priority for users:

• Increase simulation output for analysis, • Increase arrival and departure control for airport
modeling, and

• Additional objects and controls in the Rulebase.
