What is the optimum number of containers to support this operation?

80. The All Seasonings Company uses 3,200 glass jars at one of its jar-filling workstations each eight hours of production. The cycle time for a standard container, which holds 90 jars, averages 45 minutes. If management uses an efficiency factor of twenty percent, how many containers should be used?
4 containers

Feedback: Given D = 3200/8 = 400 jars per hour
T = 45/60 = .75 hour
X = .20
C = 90 jars

81. The Four Star Publishing Company uses sixty reams of paper each hour at one of its high speed printing stations. The cycle time for a standard container, which holds 15 reams of paper, averages forty minutes. If management has decided to use three containers, what efficiency factor was applied?
12.5%

Feedback: Given N = 3 containers
D = 60 reams per hour
T = 40/60 = 2/3 hour
C = 15 reams
82. A production system uses kanban cards to control production and movement of parts. One work center uses an average of 40 pieces per hour of a certain part. Standard containers hold 10 parts. The cycle time for parts containers is about 36 minutes. Management has assigned an efficiency factor of .20 to this work center. How many containers should be used to support this operation?
3 containers

Feedback: Given D = 40/hour
T = 0.6 hours, X = 0.20 and C = 10, therefore,

83. A production cell uses 240 pounds of plastic resin each 8-hour day. Resin is transported in drums that hold 100 pounds each. The material is obtained from a nearby supplier, and has a 12-hour cycle time. An efficiency factor of .15 has been assigned to this cell. What is the optimum number of containers to support this operation?
5 containers
