Tommy Nolan · Answer 1

Cycle Time = 10.19482 minute

Explanation:

From the question:

The Model E can be illustrated perfectly as shown below:

Process Time Required Predecessor Task Learning Rate

per Unit

A 9 82

B 12 A 86

C 18 B 81

D 9 C 90

E 12 D 80

F 17 E 88

G 14 F 83

H 12 G 85

I 8 H 82

Now For the minutes per week for each Process; we have:

Process Time Required Predecessor Learning Minutes

per Unit Task Rate (Week 16)

A 9 82 4.069096

B 12 A 86 6.564098

C 18 B 81 7.74841

D 9 C 90 5.9049

E 12 D 80 4.9152

F 17 E 88 10.19482

G 14 F 83 6.644165

H 12 G 85 6.264075

I 8 H 82 3.616974

The objective here is to determine the expected Cycle Time for Model E in Week 16

So, we can equally regard the Cycle Time = Bottleneck of Activity for Week 16.

Cycle Time = 10.19482 minute in as much as it is the the largest activity time for the week 16

Given that the demand per week is : = 247

The available time per week = 40 hours = 40 * 60 hours = 2400 minutes

Talk Time = Available Time Per Week/Demand Per Week

Talk Time = 2400/247

Talk Time = 9.716599

Thus; here the cycle time is greater than the talk time.
