Line Balancing Exercise

SCM $300$

AZ Devices manufactures a number of different electronic devices. One of their products is AZ$-750$ calculator. Calculators are sold every day of the month, but are only produced at the factory $5$ days per week, Monday through Friday.

Their monthly demand for these calculators is $8140.$ The factory is open $8$ hours per day. Assume an average of $22$ working days per month in the factory. You will be using daily demand, so use this information to calculate the daily demand.

LINE BALANCING $-$ PRECEDENCE DIAGRAM

Remember, the factory is open $22$ days per month. The assembly line runs $8$ hours per day. The following precedence diagram gives the necessary data to answer the line balancing related questions that follow.

LINE BALANCING $-$ PROBLEMS

Question #$1-$Make sure this answer is correct before moving on$.$

What is the CYCLE TIME that ensures the desired output rate?

$($NOTE: NEVER ROUND$-$UP YOUR CYCLE TIME!!! You should be able to figure out why this should never be done. Think about it$.)$

Question #$2$

What is the theoretical minimum number of workstations?

$($ALWAYS ROUND UP workstations. Again, you should know why,$)$

As you know, you should always round up your theoretical minimum number of workstations. Nonetheless, be aware that the calculated theoretical minimum number of workstations is not always attainable.
