$50P$ We want to design a conveyor system as shown in the figure. Three robotic arms will

be used to apply various processes to the products. The following information is given about

this system.

Customer Request: The products are requested to come out at intervals of exactly $2\mathrm{.}5$

minutes.

Nothing should take place in the $3m$ radius around the $M1$ during operation.

Nothing should take place in the area of $2m$ radius around the M$2$ during operation.$|$

Conveyor belt acceleration should be at most $1\frac{m}{s^2}$ to avoid damage to the

products. Conveyor belt speed shall be at most $1\frac{m}{s}.$

The machines can be set up to perform their operations in the following data:

M$1$: $30-50$ s $($resolution $1$s$)$

M$2$: $40-60$ s $($resolution $1$s$)$

M$3$: $45-55$ s $($resolution $1$s$)$

Neglect the distance between the point where the product reaches the belt and the

point where M$1$ is operating.

Assume that the product leaves the band when M$3$ has finished the operation.

a$)$ Write the requirement regarding the position $($distance from the beginning of the tape$)$

where M$3$ should be placed.

b$)$ There is a Customer Requirement which states the total duration of process shall be

exactly $2\mathrm{.}5$ minutes. Perform necessary analysis about the processing times of the

machines and write the requirements in accordance with the requirement writing rules.

What is this kind of requirement $/$ this method called?

c$)$ M$3$ machine paints the products with Yellow, Blue and Red, respectively, $($i$.$e$.1.$

Yellow, $2.$ Blue, $3.$ Red, $4.$ Yellow, $5.$ Blue...$).$ There is a requirement regarding the

case of errors in the paint of the products; "incorrectly painted product rate should be

$0\mathrm{.}01\%($one in ten thousand$)".$ This requirement has not been written in accordance with

the rules, so the requirement cannot be verified. Rewrite the requirement to be verifiable.

What test method would you determine $($Analysis$,$ Test, Display, Visual Inspection$)$ to

verify that the system is working in accordance with this requirement? Explain how you

would perform this test.
