Maria, the manager of the Howk-Mullen skateboard and sports equipment factory, needs to de- cide whether to purchase a small tractor-trailer imin or a forklift truck to transport the materials between the working stations in the production area. The materials-handling unit are called to move a load randomly at a mean rate of four per hour. The total time required to move a load has an exponential distribution, where the expected time would be Il minutes for the train and 8.5 minutes for the truck. The total hourly cost would be $ 60 for the train and $ 170 for the truck. Having goods waiting to be moved or in transit (i.e., idle) result in lost of productivity at their destination. This estimated cost of hile goods is $ 15 per load per hour. Maria also him established certain criteria that the materials-handling unit needs to satisfy to keep production flowing on the schedule. She would like to average no more than 40 minutes for completing the move of a load after receiving the call requesting the move. She sho would like the time for completing the move to be no more than one hour 75 percent of the time. Finally, she would like to have no more than three loads waiting to start their move at least 70 percent of the time. Please do the followin L. Obtain the vanous measures of performance if the tractor-trailer train were in be chosen Evaluate hope well these measures nicet the above criteria 2. Repeat port I if the forklift truck were to be chosen
