Excerpted from the on-line article:
The problem of component obsolescence has been around for as long as the electronics industry... Design refreshes or complete redesigns are progressively more costly options, and those with a need to quantify exactly how costly should look at the models that University of Maryland?College Park professor Peter Sandborn has developed. This work explores the field in minute detail, including such aspects as life-cycle modeling and part-obsolescence forecasting. It also attempts to quantify a matter that has more often been treated as a matter of intuition or necessity: how to optimize the interval between design revisions and redesigns over the life of a long program. In the space available here, it is impossible to do any more than mention the name of this program?the CALCE Center's MOCA (Computer Aided Life Cycle Engineering Center's Mitigation of Obsolescence Cost Analysis) program at the University of Maryland.
