Problem $8-12($Algo$)$

A firm uses a serlal assembly system and needs answers to the following:

a$.$ An output of $630$ units per shift $(770$ hours$)$ is desired for a new processing system. The system requires product to pass through

four stations where the work content at each station is $42$ seconds. What is the required cycle time for such a system?

Note: Round your answer to the nearest whole number.

Cycle time

seconds

b$.$ How efficlent is your system with the cycle time you calculated?

Note: Round your answer to $1$ decimal place.

Efficiency

c$.$ Station $3$ changes and now requires $50$ seconds to complete. What will need to be done to meet demand $($assume only $7\mathrm{.}70$ hours

are avallable$)?$ What is the efficlency of the new system?

Note: Round your answer to $1$ decimal place.

To satisfy the demand, station $3$ will

and the efficiency is

$\%.$
