Line Balance Worksheet

$57$ total points

Using the following data, fill out a Line Balance Worksheet and answer the questions regarding the

worksheet. Reference the text, page $242$ for assistance $($or the sample problem and solution

provided on Blackboard$).$ You'll need to calculate and use the $"$R$"$ value. Completely fill out the

sheet.

Submit Excel or Word file or scanned handwritten solution to the

gsjustice@niu.edu address.

Customer demand is $7400$ per day, with $(3)8-$hour shifts per day.

Use $80\%$ allowance

NOTE! In situations where operations may be overloaded:

a$.$ If there are overloads in any of the ASSEMBLY operations, you MAY consider

spreading work to "underloaded" operations

b$.$ If there are overloads in steps, $1,2,3,4,$ or $10$ your only option MAY be to add

additional LIKE stations.

Do NOT complete the HRS$/1000$ Line Balance column.

For cost problems assume a labor rate of $$21\mathrm{.}50$ per hour

Grading: $(1)$ point each entry for table completion. $(3)$ pts each for the questions.

Questions

Which are the BOTTLENECK processes?

What is the current overall$/$average load on the line?

What is the CURRENT MAXIMUM number of pieces per hour?

What would you do to make the line meet demand?

If your solution was implemented how many stations would we REALLY need?

What is the CURRENT cost per part?

What would be the cost per part if your solution was implemented?
