Our primary goal is to empower YOU! By providing you with the most advanced Diagnostics Engineering tools and expert skills, you’ll be introduced to fresh opportunities to greatly enriching ROI in design development and support activities.
Let us help you realize a comprehensive and multidisciplinary approach that leverages advanced MBSE & RAMS with “Integrated Systems Diagnostics Design” (ISDD) during Design Development, enabling a vastly enriched environment for deploying a more effective “Designing for Sustainment” capability.
Let us enable you to greatly reduce rework cycles by upscaling the collaboration opportunities within your activities and Digital Engineering processes. Substantially increase data interoperability within your design processes by integrating Systems Engineering with Testability (DFT), Test (including ATE), Reliability & Safety (FMECA, FTA’s, etc.), Embedding Diagnostics (BIT, PHM, etc.) and Supportability (ILS, Troubleshooting, IETM, PMA, etc.).
Seamlessly integrate, repurpose and multi-purpose any investment into any of these endeavors while making your competition envious of your Diagnostic Success!
eXpress is a model-based diagnostics engineering software application for the design, capture, integration, evaluation and optimization of complex or large-scale system diagnostics, prognostics, health management, testability analysis, failure mode and effects analysis and system safety analysis.
STAGE simulates aspects of Diagnostic, PHM and ISHM Engineering, showing the support capabilities of a System during its useful lifetime. Many types of analysis can be performed, including Testability, System Reliability & Mission Success, Sustainability, and Logistics Resource Allocations.
The Run-Time Authoring Tool is DSI’s solution for publishing of eXpress diagnostic design data and integration and deployment of system diagnostic and prognostic designs within real-world troubleshooting environments.
DSI Workbench allows for deployment of eXpress or user supplied diagnostics within production and maintenance troubleshooting environments.

Deploy Diagnostics for Troubleshooting
Five Simple Steps to an Intelligent IETM
eXpress’ approach and support for complex test types allows diagnostics to be generated for Intelligent IETMs:
Using the inherent power of Integrated Systems Diagnostic Design, or “ISDD”, the Expertise of the Diagnostic Design data is captured and vetted for accuracy and completeness within the eXpress diagnostic modeling process.
DSI has focused on design data interoperability for more than thirty years. We realized that, should programs or organizations make an investment into the creation of any data artifacts during the design development or the design sustainment lifecycle(s) they’re covered in either or both lifecycle(s)!
A couple of the design assessments typically performed by Reliability Engineering is the Failure Modes and Effects Analysis, or “FMEA” and the Failure Modes Effects and Criticality Analysis, or “FMECA”.
The Fault Tree Analysis, or “FTA”, is a top-down, analysis of failure propagation. It employs a deductive analysis of the failures to determine which combination of lower-level, or “primary” failures can combine to cause a “critical event” or an “undesired state” of the fielded system.

We realized that, should programs or organizations make an investment into the creation of any data artifacts during the design development or the design sustainment lifecycle(s) they’re covered in either or both lifecycle(s)!
The eXpress diagnostic modeling environment is essential for determining the diagnostic designs’ ability to “Uniquely Isolate” any failures (or loss of function). This capability, designated as “FUI” in eXpress, enables the assessment to determine if the design is able to isolate between the sensor and any of the functions contained on the object that is being sensed.
While there is plenty of leeway for interpretation or the meaning of a False Alarm (FA) as it may pertain to any particular industry or event, we will consider the FA to be the result of an incorrect indication of a “failure” as observed and reported by any sensing device.
These are two related but separate endeavors. The Design for Test (DFT) and Design for Testability (DFT)processes and objectives are very often confused among experts in the two separate design discipline(s).
In recent years, military and aerospace programs have dedicated significant resources toward research in prognostics—developing sensors and measurements that they hope will not only improve system readiness, but also reduce the costs of product sustainment.
Design for Test, Testability, Sustainment, etc. must be a robust, multiple disciplinary-inclusive design assessment activity without domain barriers that considers the sustainment objectives and any inherent diagnostic constraints of the Integrated Systems design.
Using the inherent power of Integrated Systems Diagnostic Design, or “ISDD”, the Expertise of the Diagnostic Design data is captured and vetted for accuracy and completeness within the eXpress diagnostic modeling process.
The definition of a False Alarm, unfortunately is dependent upon your specific perspective. In a very general sense, it is the improper reporting of a failure to the operator of the equipment or system.
With eXpress, your Testability Analysis is automatically created right from your eXpress model. This is one of the flagship capabilities of eXpress that was originally conceived from the very beginning – back into the 1970’s actually, with LOGMOD.
There are two (2) general approaches to capturing the IVHM (or “ISHM”) design within the eXpress environment – either using a “Top-Down” or a “Bottom-Up” approach.

The most widely used diagnostic export facility in eXpress is its Diagnostic Markup (DiagML) schema that can be used to export any eXpress-generated diagnostic sequencing in a push of a button!
As an integrated component of ISDD, we can reuse our existing Integrated Systems’ (fielded product) eXpress models in the companion Operational Support Simulation tool, “STAGE”.
The eXpress FTA Module automatically generates full-featured fault trees using data from an eXpress systems engineering model.
The FMECA Plus capability in eXpress transcends customary disciplinary barriers, allowing engineers and analysts in different areas of design to integrate the results of their respective efforts.
Significantly reduce the design lifecycles for critical and complex systems! As industry embarks on its digital transformation endeavors, DSI can assist you with greatly shortening program design lifecycle(s) by leveraging robust digital capabilities that power-up typical MBSE processes.
DSI has already “walked the walk” and also performed real-time collaborative demonstrations of robust digital threads shared by Industry partners using IEEE Standard data structures and currently available tools! Let’s leap forward today!
