Problem $6-16($Algo$)$

The desired daily output for an assembly line is $360$ units. This assembly line will operate $510$ minutes per day. The following table contains information on this product's task times and precedence relationships:

TASK TASK TIME $($SECONDS$)$ IMMEDIATE PREDECESSOR

A $35$

B $40$ A

C $30$ A

D $40$ B

E $20$ C

F $75$ C

G $45$ E$-$F

H $30$ D$-$G

What is the required workstation cycle time to meet the desired output rate?

Balance this line using the largest number of following tasks. Use the longest task time as a secondary criterion.

Note: Leave no cells blank $-$ be certain to enter $"0"$ wherever required.

What is the efficiency of your line balance, assuming it is running at the cycle time in part b$?$

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