This set of Flexible Manufacturing System Multiple Choice Questions & Answers (MCQs) focuses on “FMS Types”.
1. Which of the following are the types of Flexible Manufacturing System?
a) Sequential, Random, Dedicated, Engineered and Modular
b) Progressive, Loop, Open Field and Ladder
c) Workstations, Material Handling and Storage, Computer Control
d) Sort, Set in Order, Shine, Standardize and Sustain
View Answer
Explanation: Sequential, Random, Dedicated, Engineered and Modular are the types of FMS. Progressive, Loop, Open Field and Ladder are the types of FMS layouts. Workstations, Material Handling and Storage, Computer Control are the components of FMS. Sort, Set in Order, Shine, Standardize and Sustain are the 5S Principles.
2. How are Flexible Manufacturing Systems classified?
a) By Location
b) By Cost
c) By Number of Machines and Level of Flexibility
d) By Raw material
View Answer
Explanation: Number of Machines and Level of Flexibility are the two categories based on which FMS is classified. They are further classified based on the operations they perform. Function of a Manufacturing System is enhanced with the number of machines and flexibility in manufacturing.
3. Which type of Flexible Manufacturing System manufactures any random mix of piece part types at any time?
a) Sequential FMS
b) Engineered FMS
c) Modular FMS
d) Random FMS
View Answer
Explanation: Random mix piece part types at any time can be manufactured by Random FMS. General Purpose machines are equipped in this type to deal with the product variations. Parts with variable sequence can be produced with this method.
4. Which of the following type of FMS operates like a small batch flexible transfer line?
a) Random FMS
b) Sequential FMS
c) Dedicated FMS
d) Modular FMS
View Answer
Explanation: Sequential FMS operates like a small batch flexible transfer line. Single piece part batch type, planning, preparation needed for the next piece part batch type to be manufactured can be achieved using Sequential FMS.
5. Which of the following enables end FMS user to expand their FMS capabilities?
a) Modular FMS
b) Dedicated FMS
c) Sequential FMS
d) Random FMS
View Answer
Explanation: A Much more sophisticated system that enables the end FMS user to expand their FMS capabilities is known as Modular FMS. Production time and space is reduced through this method. It enables the FMS user to support production facility with remote control nature of the entire system.
6. Which of the following continually manufactures the same but limited mix of piece part batch types for extended periods?
a) Random FMS
b) Modular FMS
c) Sequential FMS
d) Dedicated FMS
View Answer
Explanation: System with same but limited mix of piece part batch types can be manufactured by Dedicated FMS. Limited changes can be tolerated in this system. Part variety is limited in this system since all parts are already known in advance.
7. Which of the following manufactures the same mix of part types throughout its lifetime?
a) Modular FMS
b) Engineered FMS
c) Random FMS
d) Dedicated FMS
View Answer
Explanation: Same mix of part types throughout its lifetime can be achieved by Engineered FMS. It is a systematic and model based design approach. It is a strategic based production control approach where precise parts are manufactured for a long time.
8. Which of the following is less flexible but capable of higher production rates?
a) Sequential FMS
b) Random FMS
c) Modular FMS
d) Dedicated FMS
View Answer
Explanation: Dedicated FMS is less flexible when compared with other FMS systems. Higher production rates with a limited variety of part styles can be achieved provided complete population of parts is known in advance.
9. Which consists of one CNC machining center combined with a part storage system?
a) Multi-machine Cell
b) Single Machine Cell
c) Flexible Manufacturing Cell
d) Dual Machine Cell
View Answer
Explanation: A Machine Cell with a CNC machining center and a part storage system is termed as Single Machine Cell. It can be designed to operate in a batch mode or flexible mode. Error Recovery is limited due to single machine.
10. Which of the following is more flexible at the lower production rate?
a) Engineered FMS
b) Modular FMS
c) Dedicated FMS
d) Random FMS
View Answer
Explanation: More flexibility is achieved in Random Manufacturing System. It is equipped with general purpose machines to deal with the product variations and is capable of processing parts in various sequences at lower production rates.
11. How is FMS classified depending upon the number of machines?
a) Single Machine Cell, Flexible Manufacturing Cell and Flexible Manufacturing System
b) Monofunctional, Bifunctional and Trifunctional
c) Singlet, Doublet and Triplet
d) Rotational, Linear and Angular
View Answer
Explanation: Single Machine Cell, Flexible Manufacturing Cell and Flexible Manufacturing System are the types of FMS based on the number of machines. A Single Machine Cell consists of a single CNC machining center, Flexible Manufacturing Cell consists of two or three workstations whereas Flexible Manufacturing System consists four or more processing stations.
