Signal-oriented software architecture is a trend for universal automatic test system development, and the establishment of a platform providing unifying external signal interface and testing services function is a key techniques for signal-oriented programming. Automatic-test universal supported platform isolates the use of resources and control details, hides the concrete realization of the relevant...
Transporting test program sets from one test station to another is a complicated and potentially costly task. Significant cost reductions are possible by sharing common software modules developed by other groups or reusing common modules from previous projects. The Boeing Company is a large and diverse company, often concurrently designing several large scale test stations for a variety of military...
As military budgets decline, opportunities to maintain economies of scale in weapon system production may increasingly depend upon Foreign Military Sales (FMS). FMS can also spread development costs among all customers, reducing the burden each must bear. A large scale weapon system integrator is in a unique position to observe the trends in FMS. A manufacturer based depot concept can lower up front...
Department of defense (DoD) maintenance depots face a growing challenge regarding legacy Automated Test Systems (ATS). These systems, which are critical to ensuring mission success, are increasingly difficult to maintain and repair as well as being costly to modernize or replace. According to the General Accounting Office, the DoD has estimated that they will spend billions of dollars to modernize...
This paper examines the testing and production processes used on the CASS Phase II TPS Offload Program. The CASS Phase II TPS Offload program is a US Navy acquisition to replace legacy ATE Systems using CASS (Consolidated Automated Support System) Test Stations. This provides the Navy intermediate maintenance activities an effective tool for restoring “Ready For Issue” (RFI) status for over 450 aircraft...
Test Program Set (TPS) runtime is one of the most important aspects in repair throughput. Considering the testing required to detect and isolate faults or failures and then verify repair during a typical maintenance event, the individual elements of a test program are usually executed at least twice. Any reduction in test execution time is therefore multiplied, increasing the importance of optimizing...
Open-architecture test systems were supposed to simplify TPS development, which is an effective way to preserve existing TPS investment from legacy ATE to new test systems. However, when developing test applications, we find it difficult to get perfect performance because of the formality of the interface protocols and object-levels of granularity. Objects are fine grained and not sufficiently abstracted...
