Two modules are used to feed the final assembly station on an assembly line. The final assembly station must produce 250 units in an eight-hour day
Each finished unit needs two module A's and 3 module B's. The factory uses a standard sized container that can hold 25 module A's or 35 module B's. It takes 2 hours to fill and move a container of module A's, but only 90 minutes to fill and move a container of module B's. If both module assembly processes have safety factors of 15%, how many containers should be used for each? How many hours of demand will this satisfy?
What will be an ideal response?
Answer: The number of containers is governed by this equation.
y =
yA = = 5.75 → 6 containers
yB = = 4.62 → 5 containers
Due to rounding up, there is more inventory in the system than necessary and this will support more hours of production:
Hours = =
Module A = = = 0.3 days = 2.4 hours
Module B = = = 0.23 days = 1.87 hours
