About Qualtech Systems

Qualtech Systems is a company that received a Department of Defense SBIR/STTR grant for a project entitled: Advanced Intelligent Web-Based Options to Acquire and Analyze Aircraft Health and Test Data. The abstract given for this project is as follows: Automated assessment and forecasting of aircraft health status has become a prime requirement for safety, reliability, and cost streamlining for 21st century's aviation sector. Presently, a variety of flight data, functionality, performance, and maintenance information are being collected and some are stored in databases, but an integrated health management (HM) system that utilizes all these information is virtually nonexistent. Qualtech Systems, Inc. in collaboration with Aptima, Inc. proposes developing an integrated multi-source data acquisition and analytic solution for facilitating diagnostics and prognostics, and providing decision support for operations, maintenance, logistics, supply chain, and military flight quality assurance related processes. Intelligent agent- based techniques will be used for gathering data from heterogeneous sources. Multi- disciplinary analytic techniques including signal processing, time-series-analysis, multivariate statistics, and probabilistic decision fusion, coupled with dependency model- based techniques are envisaged for the HM solution. An optimal decision-oriented user interface will satisfy information dissemination and visualization requirements. Preliminary theoretical development will involve a limited number of simulated data sources from a target naval aircraft. Software implementation and deployment of the solution on the target platform will be performed in subsequent phases of the work. The resultant integrated and flexible HM solution will have applicability across various military and commercial platforms.Qualtech Systems is a company that received a Department of Defense SBIR/STTR grant for a project entitled: Prognostics and Health Management (PHM) for Afloat Information Technology (IT) and Network Services. The abstract given for this project is as follows: Qualtech Systems, Inc., in cooperation with University of Connecticut and Lockheed Martin Corporation, propose to develop an integrated on-line and adaptive remote network PHM solution to address the needs of shipboard IT/Network systems and services. The team proposes a network system model suitable for fault localization, which takes into account the fault-to-failure progressions among the different components and/or subsystems. We also propose advanced prognostic techniques to predict discrete events (e.g., router failures), as well as continuous network performance measures (e.g., response time, throughput). The proposed solution performs smart tests (e.g., network probing, database query) on network components and coordinates multiple subsystem health assessments to arrive at an overall network health assessment. For further fault isolation, the solution provides adaptive guided troubleshooting support for the maintenance personnel onboard or onshore. In addition, the solution provides various prediction algorithms tailored to the task of projecting the future network health status for improved Maintenance and Material Management. The work proposed here seeks to developing methods for improved diagnostic accuracy (i.e., root-cause isolation), online implementation (efficient test sequences, fast inferencing), as well as the capability for Remote Diagnostics which provide opportunities to conduct diagnostics remotely and prevent breakdowns by detecting and isolating faults earlier.
