Systems Engineering and Supportability Analysis: Technology Refreshment for COTS-Intensive Systems

摘要

The desire to integrate supportability issues in product and system design has long been articulated within the systems engineering community (Asimow, 1964; Ostrofsky, 1977; Pugh, 1980). However, there has often been a lag between this intent and its execution. Supportability and serviceability analysis (traditionally, also referred to as ILS in the aerospace industry) is often relegated to a reactionary mode during detailed system design. At least partially, a contributing factor to this reality has been a hazy definition of supportability and serviceability parameters. This inhibits quantitative "dovetailing" of supportability parameters into the design and architecture synthesis activity.
