1. Each of the two sides of a hand-operated toaster can be operated independently of the other. A spring holds each side of the toaster shut, and each side must be held open in order to insert bread. Assume that the toaster is hot and ready to toast bread. The following are the elemental times necessary to perform the operations. Assume also that both hands can perform their tasks with the same degree of efficiency. Side • Place slice of bread in either side of toaster: 4 seconds. • Toast either side of bread: 30 seconds. • Turn slice of bread on either side of toaster: 2 seconds. • Remove toast from either side of toaster: 4 seconds. Side B By using a man machine chart for toasting 3 slices of bread, what method would you recommend to obtain the best equipment utilization that is, the very shortest overall time?

Answer using man and machine chart (excel).

1. Each of the two sides of a hand-operated toaster can be operated independently of the other. A
spring holds each side of the toaster shut, and each side must be held open in order to insert bread.
Assume that the toaster is hot and ready to toast bread. The following are the elemental times
necessary to perform the operations. Assume also that both hands can perform their tasks with the
same degree of efficiency.
Side
A
• Place slice of bread in either side of toaster: 4 seconds.
• Toast either side of bread: 30 seconds.
• Turn slice of bread on either side of toaster: 2 seconds.
Remove toast from either side of toaster: 4 seconds.
Side
B
By using a man machine chart for toasting 3 slices of bread, what method would you recommend to
obtain the best equipment utilization that is, the very shortest overall time?
