A FEDEP Perspective

Federation Development and Execution Process (FEDEP), IEEE 1516.3, is a standardized and recommended process for developing interoperable HLA based federations. FEDEP is an overall framework overlay that can be used together with many other, commonly used development methodologies.

Pitch Technologies’ products support the FEDEP methodology. FEDEP consists of the following steps:

1. Define Federation Objectives

During this step the objectives of the federation is developed and documented.

2. Perform Conceptual Analysis

The overall scenario to be simulated is specified. An implementation-independent overall conceptual model is developed.

3. Design Federation

Determine which simulation systems that are going to be used to simulate what processes and entities.

Pitch Visual OMT can be used to document Simulation Object Models (SOMs) for each candidate simulation.

4. Develop Federation

A Federation Agreement document that defines the interplay and responsibilities of participating systems needs to be developed. One of the most important parts is the Federation Object Model (FOM) that specifies the data interchange. Existing systems may need to be modified and new systems may need to be developed.

Pitch Visual OMT can be used to develop the FOM.
Pitch Developer Studio can be used for adapting simulations to HLA or to develop new simulations.
Pitch pRTI can be used to test federates and to verify their HLA behavior.
Pitch Recorder can be used to verify correct data exchange.

5. Plan, Integrate and Test Federation

The federates are now integrated and tested. Planning for the full-scale execution is performed.

Pitch pRTI can be used to test federates and to verify their HLA behavior.
Pitch Recorder can be used to verify correct data exchange. It can also be used to capture data in conjunction with problems to aid debugging.
Pitch Commander can be used to monitor the federates and the federation. It can also be used to verify correct behavior and detect performance issues.
Pitch GE Adapter can be used to verify behavior of simulated entities.

6. Execute Federation and Prepare Results

The entire federation is now executed and data is generated and collected.

Pitch pRTI can be used for efficient data exchange.
Adapters to DIS, HLA 1.3 and Web Services can also be used.
Pitch Commander can be used to monitor the federates and the federation.
Pitch Recorder can be used to collect data.

7. Analyze Data and Evaluate Results

Data can now be analyzed and evaluated against the goals. Using Pitch pRTI and Pitch Recorder, data can be played back for after action review, possibly using Pitch Commander and visualizing using Pitch GE Adapter. It is also possible to use Pitch Recorder to export selected parts of the simulation into analysis tools.
