8. Which type of AS/RS is a high density unit load storage system?
a) Modular AS/RS
b) Miniload AS/RS
c) Deep lane AS/RS
d) Man on board AS/RS
View Answer
Explanation: The type of automated storage and retrieval system which has the capability of high density unit load storage is known as deep lane automated and storage and retrieval system. It is appropriate for storing large quantities of stock.
9. Which type of AS/RS is used to handle small loads that are contained in bins or drawers?
a) Deep lane AS/RS
b) Miniload AS/RS
c) Man on board AS/RS
d) Modular AS/RS
View Answer
Explanation: The type of automated storage and retrieval storage system which is used to handle small loads that are contained in bins or drawers is known as Miniload AS/RS system. Retraction of materials in bins and shelves is carried out by an S/R machine.
10. Miniload AS/RS is greater than a unit load AS/RS system.
a) True
b) False
View Answer
Explanation: Miniload AS/RS is smaller than a unit load AS/RS system. It is usually enclosed concerning the safety of the items enclosed.
11. How is man on board AS/RS system often termed as?
a) Man abrade
b) Man abort
c) Man abroad
d) Man aboard
View Answer
Explanation: Man on board AS/RS system is often termed as Man aboard storage retrieval system. It is an alternative approach to the problem of retrieving individual items from storage. In this system, the worker picks individual items at their storage locations.
12. Which type of AS/RS system has retrieval system with more storage lanes and a conveyor to transport the items to a central location?
a) Man on board AS/RS
b) Modular AS/RS
c) Deep lane AS/RS
d) Automated AS/RS
View Answer
Explanation: The type of AS/RS system which has a retrieval system with more storage lanes and a conveyor to transport the items to a central location is known as Automated AS/RS system. It is similar to that of candy vending machine.
13. What is meant by VLM in a storage and retrieval system?
a) Virtual Lift Module
b) Vehicular Lift Module
c) Vertical Left Module
d) Vertical Lift Module
View Answer
Explanation: VLM means Vertical Lift Module in an automated storage and retrieval system. This type of automated storage and retrieval system is designed around a fixed horizontal aisle. It is capable of holding large inventories.
14. How many columns are there in a VLM structure?
a) Four
b) Three
c) Five
d) Two
View Answer
Explanation: The structure of a vertical Lift Module consists of two columns of trays. These are accessed by a storage and retrieval machine which delivers the trays one by one to load or unload station.
15. The aisle is horizontal in a vertical lift module.
a) True
b) False
View Answer
Explanation: In a vertical lift module, the aisle is usually designed vertically. A Vertical Lift Module with height 30 m or more saves the valuable floor facility.
