Introduction

Analysis of the core framework of the standard

Dimension	Traditional model	Requirements of this standard
Construction principles	Focus on functional implementation	Emphasis on the three-dimensional balance of credibility/completeness/reusability
Development process	Linear development model	Four-stage spiral development (concept→logic→program→V&V)
Interaction structure	Single data interaction	Three-layer entity state interaction system (base class + 2 subclasses)

Detailed explanation of key technical requirements

4.1 Key points for implementing the credibility principle

It is necessary to establish a behavior feature mapping matrix, and the correlation coefficient between the model output and the actual military exercise data is required to be ≥0.85. In the air defense combat simulation, the error of the radar detection probability model should be controlled within ±5%.

5.3 Logical process innovation

The standard clarifies the three-domain behavior model architecture for the first time:

• Physical domain: Equipment motion trajectory must comply with GJB 8070.1-2013 coordinate specification
• Information domain: Electromagnetic spectrum data must be marked with timestamp accuracy (±10ms)
• Cognitive domain: Decision tree depth should be no less than 3 layers

Typical application case

After a joint campaign simulation system adopted this standard:

1. Model reuse rate increased by 40%
2. Interactive data packet volume reduced by 35%
3. V&V cycle shortened by 25%

Analysis of Standard Evolution

Compared with the GJB 7099 series standards, the breakthroughs of this standard are:

Version	Focus	Technical Features
GJB 7099.1-2010	Conceptual Model	Static Behavior Description
GJB 9422-2018	Dynamic Simulation	Introduction of Machine Learning Elements (Clause 5.3.4)

Implementation Suggestions

Model development phase

It is recommended to use component-based encapsulation (Clause 5.4). The code volume of a single functional module should be controlled within 2,000 lines, and the interface parameters should strictly follow the XML Schema definition of Clause 7.2.

Verification and testing phase

A three-level verification system needs to be established:

• Unit testing: covering all behavioral decision branches
• Integration testing: verifying that the interaction sequence complies with Clause 6.1
• Actual combat verification: using JNLC (Joint Training Scenario) data comparison
