Introduction to Supply Chain Management Problem 1: Line Balancing (11 points) 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: Task A B C D E F G Predecessor none none A B D E C, F Average Time (sec) 30 15 20 15 10 10 30 The Plant Manager needs first shift to achieve an output of 600 washing machines each day. a) Compute the Takt time for the line (2 points). b) What is the theoretical minimum number of workstations? (2 points) c) Draw the precedence diagram, and then create work stations. Follow the “most following tasks” heuristic rule to assign these tasks to the work stations. Show which tasks are assigned to each workstation (3 points). d) Compute the efficiency and percent idle time for the system (2 points). e) What is the maximum output that could be achieved by a single assembly line in 7 hours? (2 points) Problem 2: Line Balancing (8 points) An assembly line has a production time of 20 hours/day and required output of 500 units per day. Tasks are assigned to workstations in the following manner. Workstation #1 B 60 sec Workstation #2 A 40 sec Workstation #3 G 40 sec Workstation #4 H 60 sec C 30 sec F 30 sec E 30 sec D 30 sec J 40 sec K 30 sec I 50 sec a) Calculate the idle time (in seconds) incurred for each unit produced on the assembly line (2 points). b) Calculate the percent idle time for the assembly line (2 points). c) Calculate the efficiency for the assembly line (2 points). d) Which workstation will have the most idle time? (2 points) Problem 3: Supplier Selection (6 points) Your sourcing department has received bids from three suppliers shown below. PERFORMANCE DIMENSION IMPORTANCE Supplier 1 Supplier 2 Supplier 3 On Time Delivery (% on time) Financial Stability (rating) Cost ($/unit) 0.50 92% 99% 85% 0.10 0.40 AA $4.18/unit A $4.38/unit AAA $3.99/unit a) Score each supplier‘s bid using the following scale (3 points). On Time Delivery Range Score $4.35 per unit $4.26-$4.35 per unit $4.16-$4.25 per unit $4.00-4.15 per unit

Problem 1
(a)
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
