This set of Industrial Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Process Chart Symbols”.
1. Which of the following symbol represents inspection activity?
a) 
b) 
c) 
d) D
View Answer
Explanation: Process chart uses symbols to represent various activities. Activity – INSPECTION is symbolically represented by the
(square). A circle represents operation activity. Arrow represents transportation and D is for delay.2. What does a small circle represent in process chart?
a) Operation
b) Storage
c) Delay
d) Inspection
View Answer
Explanation: A small circle in a process chart represents operation i.e., it represents some operation is being performed in the process. Storage is represented by an inverted equilateral triangle. Delay by D and inspection by a square.
3. How a storage activity is symbolically represented in a process chart?
a) An equilateral triangle standing on its vertex
b) A large capital D
c) A small arrow
d) A small square
View Answer
Explanation: A storage activity in a process chart is represented by using an equilateral triangle standing on its vertex i.e.,
. D indicates delay, arrow for transport and square for inspection.4. Match the following.
p) Therbligs i) Macroscopic motion q) SIMO chart ii) Microscopic motion r) Process chart
a) p – ii, q – i, r – ii
b) p – ii, q – ii, r – i
c) p – i, q – ii, r – ii
d) p – ii, q – i, r – i
View Answer
Explanation: SIMO chart is used in microscopic motion analysis in which therbligs are used to define elemental activities. In macroscopic motion analysis, a process chart is used. SIMO stands for simultaneous motion chart.
5. What “D” represents in a process chart?
a) Operation
b) Storage
c) Delay
d) Inspection
View Answer
Explanation: “D” in a process chart is used to represent the delay in the process. It is used to represent that there exists a delay in the process at a given stage. Inspection is represented by a small square. Operation and storage are represented using a circle and an inverted equilateral triangle respectively.
6. Arrange the following as per the method study procedure.
(i) Record
(ii) Select and define
(iii) Install a new method
(iv) Develop a new method
(v) Maintain a new method
(vi) Critical examination
a) ii, i, vi, iv, iii, v
b) v, i, iv, iii, ii, vi
c) vi, i, v, iii, ii, vi
d) vi, i, iv, iii, ii, v
View Answer
Explanation: Method study or motion study consists of a sequence of steps. They are in order as follows:
i. Select and define
ii. Record
iii. Critical Examination
iv. Develop a new method
v. Install a new method
vi. Maintain a new method
7. Match the following.
p) Starting a motor i) Operation q) Finished goods kept in warehouses ii) Inspection r) Refrigerators in the stock room iii) Storage s) Gauging a component
a) p – iii, q – i, r – ii, s – iii
b) p – iii, q –ii, r – i, s – iii
c) p – i, q – iii, r – ii, s -ii
d) p – i, q – iii, r – iii, s – ii
View Answer
Explanation: Starting motor is an example of an operation. Likewise, finished goods kept in warehouses, refrigerators in the stock room are examples of storage. Gauging a component is an example of inspection.
8. How transport is represented in a process chart?
a)
b)
c)
d) D
View Answer
Explanation: Transpose activity in a process chart is represented by using a symbol
. It represents the movement of goods from one place to another place. Circle represents an operation and square represents an inspection.9. Which of the following best suites to represent the activity “articles are being painted as they are transported by the chain conveyor”?
a)
b)
c) 
d) D
View Answer
Explanation: “Articles are being painted as they are transported by the chain conveyor” is a combined activity. Both operation and transportation are being done simultaneously. Hence, it is represented using the symbol
.10. Which of the following symbol represents the combined activity “Inspection cum operation”?
a) 
b)
c)
d) D
View Answer
Explanation: Inspection cum operation is a combined activity that is represented using the symbol
.As inspection is a more important activity, it is represented outer. The activity with less importance is represented inner.
11. Which of the following represents the combined activity “a powder milk tin is being weighed as it is filled”?
a)
b)
c)
d) D
View Answer
Explanation: Both events occur simultaneously and are being controlled automatically. The filling is an operation and the weighing is an inspection. Hence, the combined activity is operation cum inspection. The event with utmost importance is represented first on the outer and the one with less importance on the inner.
