Question
Chapter 6, Problem 20P
Summary Introduction
Interpretation: Balance delay when assembly line is 65% efficient is to be calculated.
Concept Introduction: An assembly line is a sequence of work in which an output is produced by adding inputs to semi-finished goods which moves from work station to another work station.

a. What is the maximum hourly output rate from this line?
(Hint:
The line can only go as fast as its slowest workstation.)
The maximum hourly output rate is
nothing
calculators per hour. (Enter your response as an integer.)
B. What cycle time corresponds to this maximum output rate?
C. If a worker is at each station and the line operates at this maximum output rate, how much idle time is lost during each? 10-hour shift?
D. What is the line's efficiency?
To meet holiday demand, Alex's Pie Shop requires a production line that is capable of
producing 50 pecan pies per week, while operating only 40 hours per week. There are only
four steps required to produce a single pecan pie with respective processing times of 5
minutes, 5 minutes, 45 minutes, and 15 minutes.
a. What should be the line's cycle time?
b. What is the smallest number of workstations Alex could hope for in designing the
line considering this cycle time?
c. Suppose that Alex finds a solution that requires only four stations. What would be
the efficiency of this line?
what is finding the bottlenecks in the process?
