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. Side B Turn slice of bread on either side of toaster: 2 seconds. Remove toast from either side of toaster: 4 seconds. 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?

A worker is currently responsible for tending two machines in a machine cluster. The service time per machine is 0.35 min and the time to walk between machines is 0.15 min.The machine automatic cycle time is 1.90 min. If the worker’s hourly rate = $12/hr andthe hourly rate for each machine = $18/hr, determine (a) the current hourly rate for thecluster, and (b) the current cost per unit of product, given that two units are produced byeach machine during each machine cycle. (c) What is the percent idle time of the worker?(d) What is the optimum number of machines that should be used in the machine cluster, ifminimum cost per unit of product is the decision criterion?
