Yes, Just in Time has it's problems because it typically does not allow for catastrophes. Of course, second sourcing is pretty common but requires time to get parts in-house and, when an event such as those occur, second sources will often not have enough product available to meet the requirements.

Wow - what a bunch of idiots for not thinking of that and shutting assembly lines down instead.

The industry standard "Just in Time" supply chain does not work with major disruptions like the one in Japan. I am surprised by the lack of 2nd sourcing of the air sensors and wondering why auto manufacturers did not insist on physically separate and possibly completely independent second sources for all key components. This is a basic failure of risk management 101. One may argue that "who would have expected this?" but that is not a valid argument; earthquakes in Japan (and elsewhere) are not unusual nor unexpected. Yes the magnitude was significant but then again not a 1 in a million type of occurrence. We should learn from this experience and develop contingency plans for any major production area or specialized part supplier.

This is a unfortunate situation. However, automobile design can also be done with employing part with alternate vendor / alternate part number. This will help in situation like this.

Hitachi airflow sensors from japan is now in short suppy or not available so the vehicle manufactures globaly sorting to reduced production or halt the production. Now japanese manufactures needs to think and start their ancilary units in other countries for those products whih are marketed globally.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
