Abstract:

There is another Year-2000 risk, distinct from the more widely reported risks
concerning impending failures of computers and software which represent dates
using two digits for the year. The risk involves date sensitive embedded
systems (built-in silicon chips, such as microprocessors, timers, sequencers
and controllers) which are essential to the operation of a vast portfolio of
infrastructures; from medical pacemakers, to buildings (phone, security,
heating, plumbing and lighting), to transportation, to financial networks, to
just-in-time delivery systems, and so on. According to a recent study, the
firmware (permanently loaded software) that enables these chips to run is
date sensitive and not Year-2000-compliant in approximately 1 to 3 percent of
the 50 billion embedded systems that will be installed worldwide by the end
of the century. This small fraction will fail, causing the systems they
control to begin failing around 1 January 2000 and for the first few years of
the new century. These failures are coupled with significant factors
mitigating their diagnosis and repair, including the absence of reliable
documentation of Year-2000-compliance of date sensitive chips produced over
the past few decades, posing formidable assessment issues.
