PART - A
Where to apply FMS technology?
Answer
FMS technology is applied in mid-volume, mid-variety production environments where there is a need for high flexibility, reduced lead times, and improved machine utilization, typically for parts requiring complex machining operations.
Compare and contrast various FMS work stations.
Answer
FMS workstations include load/unload stations, machining stations, and assembly stations. Machining stations are designed for material removal (e.g., CNC mills/lathes), whereas assembly stations focus on joining components. While all require automated material handling interfaces, machining stations prioritize tool management and chip removal, while assembly stations prioritize precision positioning and fastening.

In order to determine the number of vehicles required to meet the demand for a particular automated guided vehicle system. The system must be capable of making 40 deliveries per hour. The following are the data of performance characteristics of the system.
Vehicle velocity = 150 m/min
Average distance travelled per delivery = 450 m
Pickup time = 0.75 min
Drop off time = 0.75 min
Average distance travelling empty = 300 m.
Traffic factor = 0.9
Determine the number of vehicles required to meet the demand of delivery. Also determine the handling system efficiency?
