As part of a major plant renovation project, the industrial engineering department has been asked to balance a revised assembly operation to achieve an output of 240 units per eight-hour day. Task times and precedence relationships are as follows:
Task Duration Immediate
(minutes) Predecessor
a 0.2 -
b 0.4 a
c 0.2 b
d 0.4 -
e 1.2 d
f 1.2 c
g 1.0 e, f
Do each of the following:
A. Determine the minimum cycle time, the maximum cycle time, and the calculated cycle time.
The minimum cycle time minutes
The maximum cycle time minutes
Calculated cycle time minutes
B. Determine the minimum number of stations needed.
C. Assign tasks to workstations on the basis of greatest number of following tasks. Use longest processing time as a tiebreaker. If ties still exist, assume indifference in choice.
Work stations Following Tasks
I (A, B, D, C) ( A, B, C, D) ( D, C, A) ( A ) ( D, B, C)
II (E) ( D, C, A) (C, F, B) (A) (B, E)
III (B) (F) (F, G) (E) (C)
IV (A, B, C) (E, F) (G) (E) (C, D)
D. Compute the percentage of idle time for the assignment in part d. Use the actual bottleneck cycle time in your calculation.

This problem has been solved! see the answerwhich of the following statements is correct? the consumer price index is a measure of the overall level of prices, whereas the gdp deflator is not a measure of the overall level of prices. if, in the year 2011, the consumer price index has a value of 123.50, then the inflation rate for 2011 must be 23.50 percent. compared to the gdp deflator, the consumer price index is the more common gauge of inflation. the consumer price index and the gdp deflator reflect the goods and services bought by consumers equally well.

Faldo corp sells on terms that allow customers 45 days to pay for merchandise. its sales last year were $325,000, and its year-end receivables were $60,000. if its dso is less than the 45-day credit period, then customers are paying on time. otherwise, they are paying late. by how much are customers paying early or late? base your answer on this equation: dso - credit period = days early or late, and use a 365-day year when calculating the dso. a positive answer indicates late payments, while a negative answer indicates early payments. a. 21.27b. 22.38c. 23.50d. 24.68e. 25.91b
