DSI International routinely contributes new concepts to the diagnostics and testability industry. Among our contributions are papers presented at industry conferences. Each of the following papers identify true breakthroughs in technology.
Abstract: Everything will fail at some point and this paper examines several approaches to assess and analyze failures with particular focus on FMEA and FTA and how they can be used to help mitigate failures.
Click to viewAbstract: The purpose of this paper is to explore the impact of those boundaries of traditional design development independent approaches and to then to discuss specific areas that effectively add value by permeating such boundaries through the implementation of advanced design development interdependent approaches
Click to viewAbstract: The IRP thesis purpose is to develop a novel approach to IVHM that combines diagnostic analysis such as Detection and Isolation Statistics and Advanced FMECA. The software tool used to provide a creative diagnostic design is called eXpress. This project complements the design phase of an Unmanned Aerial Vehicle (UAV) fuel system from an IVHM perspective.
Click to viewAbstract: The paper investigates the effects of system design on its maintenance requirements. This becomes significantly important when investigating fault alarms that cannot be verified, diagnosed or even duplicated under standard manual inspection regimes.
Click to viewAbstract: The purpose of this study is to suggest a modified approach that compensates some shortcomings of RPN with relevant strength of ASIL for Safety System and suggests systematic and logical approach for FMEA.
Click to viewAbstract: A fast and effective method of modeling System Boundary Scan using the eXpress Testability Analysis Tool has been developed. Testability questions surrounding the inclusion of Boundary Scan in a system design,specifically Functional Coverage (what is is not tested) and Diagnostics, can now be addressed using the eXpress modeling tool.
Click to viewAbstract: This paper examines issues associated with the application of HDM to hierarchical systems, including: the types of diagnostic inference used to interpret the relationships between functions and failure modes, the correlation of functional and failure-based reliability data, and diagnostic assessment using Hybrid Diagnostic Models.
Click to viewAbstract: This paper highlights the importance of data type extensibility for preventing software obsolescence in Automatic Test Systems. It describes solutions proposed by the authors for supporting such extensibility in several interfaces of Automatic Test Systems.
Click to viewAbstract: This paper will discuss the use of diagnostic simulations to generate the Fault Resolution metric for a system or equipment.
Click to viewAbstract: This paper exposes some major deficiencies inherent within current methods for assessing design Testability—critical shortcomings that not only might cause adherence to contracted Testability requirements to be in conflict with long-term maintenance goals (such as Life Cycle Cost and Operational Availability), but could also result in evaluations that fail to predict the actual diagnostic behavior of the system or device.
