Problem 1 Line Balancing First shift employees at GE Applian
Problem 1: Line Balancing First shift employees at GE Appliances work from 2pm-10pm Monday through Friday assembling washing machines. Everyone on the assembly line is allowed a 30 minute lunch and two 15 minute breaks. The assembly line stops while associates are on lunch or break. The processes of the assembly line have the following dependencies: Average Time (sec) 30 15 20 15 10 10 30 Task Predecessor none none C, F The Plunt Manager nesstst t ines a) Compute the Takt time for the line
Solution
To be calculated:
Takt time
Given values:
Shift timings = 2pm to 10pm
Number of hours in the shift = 8 hours
Available time in the shift = 480 minutes
Break time = 2 x 15 minutes = 30 minutes
Lunch time = 30 minutes
Net working time = 480 - 60 = 420 minutes
Net working time = 420 x 60 = 25200 seconds
Net working time in the shift = 25200 seconds
Required output = 600 washing machines per day
Solution:
Takt time is calculated as;
Takt time = Available work time / Demand rate
Takt time = 25200 / 600
Takt time = 42 seconds per washing machine
