Question 1 2 pts As an expert in Lean Systems, you've been assigned the task of determining the number of kanban trays that should be placed between two machines. The trays represent the work-in-process inventory necessary between the upstream machine and the downstream machine. The following information is available to you: Average leadtime = 2.0 hours Average demand = 50 parts per hour Desired safety stock - 10% of average demand during leadtime (DDLT) Each kanban tray holds 40 parts What is the exact calculation for the number of kanban trays needed for this process? 3.00 trays 2.625 trays O 2.75 trays 2.00 trays Question 4 2 pts As an expert in Lean Systems, you've been assigned the task of determining the number of kanban trays that should be placed between two machines. The trays represent the work-in-process inventory necessary between the upstream machine and the downstream machine. The following information is available to you: Average leadtime = 2.0 hours Average demand = 50 parts per hour Desired safety stock = 10% of average demand during leadtime (DDLT) Each kanban tray holds 40 parts Safety stock needs to be considered when determining the number of kanban trays because: safety stock does NOT need to be considered when determining the number of kanban trays O the leadtime varies the container size varies the demand varies 2 pts Question 5 As an expert in Lean Systems, you've been assigned the task of determining the number of kanban trays that should be placed between two machines. The trays represent the work-in-process inventory necessary between the upstream machine and the downstream machine. The following information is available to you: Average leadtime = 2.0 hours Average demand = 50 parts per hour Desired safety stock = 10% of average demand during leadtime (DDLT) Each kanban tray holds 40 parts The relationship between the number of kanban trays needed and the size of the tray is best described as: as tray size increases, the number of kanban trays increases linearly as tray size increases, the number of kanban trays decreases as a step function due to whole trays being needed as tray size increases, the number of kanban trays decreases linearly as tray size increases, the number of kanban trays increases as a step function due to whole trays being needed
