A test and diagnostics capability is being developed for a motion control subsystem that consists of the following hardware: a motion control IC (Integrated Circuit), an interconnect between motion control IC, an H-switch current driver, an interconnect between H-switch current driver, a motor, and an optical encoder.
The elements of the motion control subsystem are as follows:
$$
\begin{aligned}
& x_1=\text { motion control IC } \\
& x_2=\text { interconnect } 1 \\
& x_3=\text { H-switch current driver } \\
& x_4=\text { interconnect } 2 \\
& x_5=\text { motor } \\
& x_6=\text { optical encoder }
\end{aligned}
$$
If a motion control subsystem failure exists, a self-test could describe the failure in the following bea: $m=(0.2,0,0.3,0,0,0.5)$. This nested structure is based on the level of hardware isolation of the diagnostic software. This isolation is hierarchical in nature. You first identify a motion control subsystem failure $m\left(\mathrm{~A}_6\right)$ that includes a possibility of any component failure $\left(x_1, x_2, x_3, x_4, x_5, x_6\right)$. The test then continues and, due to isolation limitations, a determination can be made of the failure possibility consisting of $m\left(A_3\right)$, subset $\left(x_1, x_2, x_3\right)$, followed by the ability to isolate to an $x_1$ failure if $x_1$ is at fault. Basic evidence assignments are constructed from empirical data and experience.
Find the associated possibility distribution and draw the nesting diagram.
