The TEAMS model analyzer is a supporting tool developed to work with models created with TEAMS (Testability, Engineering, and Maintenance System), which was developed by QSI.
In an effort to reduce the time spent in the manual process that each TEAMS modeler must perform in the preparation of reporting for model reviews, a new tool has been developed as an aid to models developed in TEAMS. The software allows for the viewing, reporting, and checking of TEAMS models that are checked into the TEAMS model database. The software allows the user to selectively model in a hierarchical tree outline view that displays the components, failure modes, and ports. The reporting features allow the user to quickly gather statistics about the model, and generate an input/output report pertaining to all of the components. Rules can be automatically validated against the model, with a report generated containing resulting inconsistencies.
In addition to reducing manual effort, this software also provides an automated process framework for the Verification and Validation (V&V) effort that will follow development of these models. The aid of such an automated tool would have a significant impact on the V&V process.

Overview
The document is a Technical Support Package for the TEAMS Model Analyzer, version 1.0.0.1, developed by NASA's Jet Propulsion Laboratory (JPL). It is part of NASA Tech Briefs (NPO-46842) and aims to disseminate information about aerospace-related developments with potential wider technological, scientific, or commercial applications.
The TEAMS Model Analyzer is a tool designed to assist users in analyzing and checking models related to aerospace systems. The document outlines several key features and functionalities of the software, which include:
-
Model Checking: The Model Checker feature allows users to execute a set of selected rules against a chosen model. Any violations of these rules are logged in an Activity Log, which provides details such as the rule name, object type, and the location of the object within the model.
-
Reporting Capabilities: The Reports section displays a variety of available reports related to the selected TEAMS model. Users can generate reports in a datasheet view, which includes an Input/Output Report that presents a comprehensive table of all components in the model, excluding failure modes. This report includes columns for Direction, Port Name, Source, Source Path, From/To, From/To Port Name, and Type.
-
Model Hierarchy and List: The document describes a Model List that shows all TEAMS models checked into the database, with the selected model highlighted in a tree view format. The Model Hierarchy feature provides a structured view of the model, including modules, failure modes, and input/output ports.
-
User Support and Compliance: The document emphasizes compliance with U.S. export regulations and notes that it may contain proprietary information. It also provides contact information for further assistance, directing inquiries to the Innovative Technology Assets Management team at JPL.
Overall, the Technical Support Package serves as a comprehensive guide for users of the TEAMS Model Analyzer, detailing its functionalities, reporting features, and support resources. It underscores NASA's commitment to sharing technological advancements and fostering innovation in aerospace-related fields.
