Dr. Lori Baker, operations manager at Nesa Electronics, prides herself on excellent assembly-line balancing. She has been told that the firm needs to complete 120 instruments per 24-hour

day. The assembly-line activities are:

Task	Performance Time (mins)		Predecessors	Task	Performance Time (mins)		Predecessors
A	4			G	5		F
B	6			H	7		D, E
C	8		A	I	2		H
D	7		A, B	J	9		E
E	3		B	K	1		G, I, J
F	5		C

This exercise only contains parts b, c, d, e, f, and g.

b) For the given daily (24-hour) production rate of 96 units, the highest allowable cycle time = 15 minutes (enter your response as a whole number). c) If the cycle time after allowances is given as 10 minutes, then the effective daily (24-hour) production rate = 144 units (enter your response as a whole number). d) For the given 10-minute cycle time after allowances, the theoretical minimum number of workstations = 6 (round your response up to the next whole number). e) Using the longest assigned task time of all of the workstations and 6 workstations, the operating efficiency of the assembly line = 93.33% (enter your response as a percentage rounded to two decimal places). f) Using the 10-minute cycle time after allowances and 6 workstations, the idle time for the assembly line per cycle = 4 minutes (enter your response as a whole number). g) The correct precedence relationship with one of the possible assignments of tasks to workstations for the given 10-minute cycle time is shown in Fig. 1 Fig. 1 Fig. 2 Fig. 3
