Integrated Reliability and Economic Modeling for Transmission Across Large Regions: A Space Odyssey

Power flow modeling and stability analysis are needed to more-comprehensively assess system reliability but the development of the system portfolios and conditions require use of economic models (e.g., production cost). What are the state of art methods for efficiently linking economic and reliability models to enable examination of multiple snapshots and perform detailed nodal analyses?

RELIABILITY PROGRAMS FOR ''L'' SYSTEMS

The AFSC Program Structure assigns numbers and letters to the various programs in order to identify the efforts for management control. The fact that most of the command and control systems have the designator "L" affixed has prompted the reference to them as the "L" systems. In this paper the mission of "L" systems has been described, the complexity of the equipment indicated, and the importance of these systems to our national defense efforts pointed out. The efforts by the Electronic Systems Division to comply With the Air Force policy that a comprehensive reliability program be required for each contract to assure delivery of reliable systems and equipment to the Air Force inventory are described in considerable detail.

Methodology for Physics and Engineering of Reliable Products

Physics of failure approaches have gained wide spread acceptance within the electronic reliability community. These methodologies involve identifying root cause failure mechanisms, developing associated models, and utilizing these models to inprove time to market, lower development and build costs and higher reliability. The methodology outlined herein sets forth a process, based on integration of both physics and engineering principles, for achieving the same goals.

Reliability Investigation of Ball Grid Array Assemblies for Space Flight Applications

JPL, in a partnership with an industrial consortium, is currently engaged in the investigation of reliability and quality issues if ball grid array (BGA) packages as they may be applied to space flight electronics. Performing tests to determine the solder joint reliability of assemblies using BGAs under temperature cycling has proved to be a real challenge for test engineers.
