Cost of ownership is always a hot topic when making a program decision for any new, upgrade or sustainment option. The criteria for developing a Total Cost of Ownership (TCO) model quickly turns into debates with many facets and lots of emotion. When it comes to the cost of acquiring and operating test equipment, the answer is not any easier to determine. However, if looked at from a Product Life...
A brief review of some issues seen in the replacement of older special production equipment with COTS will be given followed by an in-depth analysis of the rehost of an older program to a new station, the issues found after it was fielded, and an analysis of what the issues were and a solution from the engineering and managerial viewpoints.
Throughput demands and cost-down pressures involved with modern functional testing necessitate a trend towards a parallel test paradigm. Parallel test techniques can be employed by test engineers to overcome these challenges. The benefits of conducting tests on multiple units/subsystems concurrently are to maximize instrumentation utilization, increase throughput and reduce execution time. This paper...
The ATML family of standards have now been published through the IEEE and are beginning to be implemented in the test industry. This paper explores two of these ATML standards, the IEEE Std 1671.6 ATML Test Station Description and the IEEE Std 1671.5 ATML Test Adapter Description. These standards describe a test station and test adapter in an electronic format adhering to the XML standard. A description...
This Paper examines the evolution of the Harmonization approach for the LM-STAR® Multi-National Support. Critical to the Lockheed Martin Corporation's approach to winning the JSF/F35 contract in 2002 was developing a common logistics approach. A strategy was devised for ATE Harmonization whereas all Original Equipment Manufacturers (OEMs) would utilize a common ATE subset solution knowing one day...
Reconfigured Parallel Test Grid (RPTG) technology advanced a novel theory to improve test and ATE using efficiency. In order to analyze the function and efficiency of RPTG, it is important to simulate the RPTG environment authentically. Based on parallel and reconfigured characteristic of RPTG, HLA-based layered analytic simulation architecture was put forward. This solution can exploit the parallelism...
Overcoming test-equipment obsolescence is paramount in military and aerospace applications where test systems are supporting equipment with a service life of more than 20 years. However, replacing one or more obsolete instruments in a test system can have major consequences for the deployed Test Program Set (TPS). An emulation strategy can help you incorporate new test instruments to migrate from...
We describe the conclusions of a technology and communities survey supported by concurrent and follow-on proof-of-concept prototyping to evaluate feasibility of defining a durable, versatile, reliable, visible software interface to support strategic modularization of test software development. The objective is that test sets and support software with diverse origins, ages, and abilities can be reliably...
Advanced diagnostic reasoners are being developed to make use of Bayesian fault probability distributions, experiential learning algorithms and actual net centric historical failure data to change dynamically or optimize the testing sequence. What is not covered is how also to reconfigure dynamically the system or unit under test and the test equipment from its present state to the state required...
