This set of Flexible Manufacturing System Multiple Choice Questions & Answers (MCQs) focuses on “Material Transport System – Vehicle Management”.
1. Which of the following purpose is to eliminate interference between vehicles and to prevent collision?
a) Operator Control
b) Traffic Control
c) Frequency Control
d) Automation Control
View Answer
Explanation: The sole purpose of traffic control is to eliminate the interference between the vehicles and to prevent collision. It can be accomplished by the application of sensors and monitoring system by mounting to the vehicle.
2. Which must be allocated to the vehicles to minimize waiting times in the layout?
a) Recycling Tasks
b) Production Tasks
c) Delivery Tasks
d) Assembly Tasks
View Answer
Explanation: In order to minimize the waiting times in the layout, delivery tasks must be allocated to the vehicles at the load or unload stations. To achieve this objective effectively, the vehicles must be well managed.
3. Which of the following technique is also known as forward sensing?
a) Angular Sensing
b) Onboard Sensing
c) Off board Sensing
d) Mixed Sensing
View Answer
Explanation: Onboard Sensing technique is also known as forward sensing. In order to detect the presence of other vehicles and obstacles in the pathway, one or more sensors are mounted on each vehicle.
4. When the obstacle is removed, the vehicle stops in the on board sensing technique.
a) True
b) False
View Answer
Explanation: When the vehicle is removed, the vehicle moves in the onboard sensing technique. At the same time, when there is an obstacle in the pathway the vehicle stops suddenly at a distance relative to the obstacle.
5. Which of the following technique prohibits the vehicle from entering a zone that is already occupied by another vehicle?
a) Angular Sensing
b) Off board Sensing
c) Onboard Sensing
d) Zone Control
View Answer
Explanation: Zone Control technique prohibits the vehicle from entering a zone that is already occupied by another vehicle. In this technique, the Automated Guided Vehicles layout is divided into different zones and each zone is monitored.
6. Which parameter of the zone is designed considering the factors such as number of vehicles, size and complexity of the layout?
a) Circumference
b) Radius
c) Height
d) Length
View Answer
Explanation: In Zone control technique, on considering the factors such as number of vehicles, size and complexity of the layout, the length of the zone is determined. It should also consider allowances for the vehicles for safety precautions.
7. The zones are much larger than the vehicle length.
a) True
b) False
View Answer
Explanation: In Zone Control technique, the zones are much larger than the vehicle length. If the zones are designed shorter, then the length of vehicles and the number of vehicles in the system would affect the objective of this technique.
8. Which of the following method operates with a single frequency throughout the guide path layout?
a) Operator Method
b) Pathway Method
c) Frequency Select Method
d) Path Switch Select Method
View Answer
Explanation: In order to operate with a single frequency throughout the guide path layout, path switch select method is used. The power will be turned off in all other branches except the path the vehicle is to travel on.
9. Which of the following monitors the location and movement of each vehicle in the system?
a) Actuators
b) Machines
c) Operator
d) Central Computer
View Answer
Explanation: The function of a Central Computer is to monitor the location and movement of each vehicle in the system. Zone Control technique is established using this central computer in order to eliminate collision.
10. Which of the following process is important for an AGV to achieve its function?
a) Inspecting
b) Dispatching
c) Testing
d) Storing
View Answer
Explanation: Dispatching the vehicles in a timely manner is important for an AGV to achieve its function. It must be done efficiently to the points in the system where they needed using the given resource at the given time.
12. Which of the following involves transmitting a hailing signal for any available vehicle in the neighborhood?
a) Resistor Control Station
b) On board Panels
c) Remote Call Stations
d) Guided Wire
View Answer
Explanation: In Remote Call Stations, hailing signal is transmitted for any available vehicle in the neighborhood to dock at the station and either pick up or drop off a load. It is another method for an AGV to satisfy delivery requirement.
13. Which of the following technique provide the AGVs with flexibility and timeliness to cope with the changes in customer requirements?
a) Onboard Control Panels
b) Guided Wires
c) Magnetic Tapes
d) Resistors
View Answer
Explanation: In order to cope up with the changes in customer requirements, on board control panels are typically preferred. They provide the Automated Guided Vehicles the required flexibility in handling the variety of components.
