<b>Abstract:</b>

<p>Component reuse in multiple products has become a
popular way to take advantage of the economies of scale
across a family of products. Amongst electronic system
developers there is a desire to use common electronic parts
(chips, passive components, and other parts) in multiple
products for all the economy of scale reasons generally
attributed to platform design. However, the parts in electronic
systems (especially those manufactured and supported over
significant periods of time), are subject to an array of longterm
lifecycle supply chain disruptions that can offset savings
due to part commonality depending on the availability of finite
resources to resolve problems on multiple products
concurrently. In this paper we address the application of
product platform design concepts to determine the best reuse
of electronic components in products that are subject to longterm
supply chain disruptions such as reliability and
obsolescence issues. A detailed total cost of ownership model
for electronic parts is coupled with a finite resource model to
demonstrate that, from a lifecycle cost viewpoint, there is an
optimum quantity of products that can use the same part
beyond which costs increase. The analysis indicates that the
optimum part usage is not volume dependent, but is dependent
on the timing of the supply chain disruptions. This work
indicates that the risk and timing of supply chain disruptions
should be considered in product platform design.
