Question 1

Decision variables are
A) Controllable
B) Uncontrollable
C) Parameters

Decision variables are controllable inputs in a mathematical model, representing choices available to the decision-maker.

Question 2

A physical model is an example of
A) An iconic model
B) An analogue model
C) A verbal model
D) A mathematical model

Accepted Answer

Iconic models are physical representations or direct replicas of the objects they represent, making a physical model an example of an iconic model.

Question 3

Every mathematical model
A) Must be deterministic
B) Requires computer aid for solution.
C) Represents data in numerical form
D) All of the above

Accepted Answer

Mathematical models often represent data in numerical form to analyze, interpret, or simulate real-world scenarios. They do not necessarily have to be deterministic or require computer aid for solutions, as some can be probabilistic or solved manually.

Question 4

An optimization model
A) Mathematically provides best decision
B) Provides decision with limited context
C) Helps in evaluating various alternatives constantly
D) All of the above

Accepted Answer

An optimization model mathematically provides the best decision by evaluating various alternatives within a given context, thus encompassing all the aspects mentioned.

Question 5

A) Military
B) Business
C) Administration'
D) All of the above

Accepted Answer

Operations research is applied in various fields including military, business, and administration to optimize decision-making and improve efficiency.

Question 6

Operations Research techniques helps to find ………. . solution
A) Feasible
B) Non feasible
C) Optimal
D) Non optimal

Accepted Answer

Operations Research techniques are designed to find the optimal solution to a problem, which means the most efficient and effective solution given the constraints and objectives of the problem.

Question 7

OR provides solution only if the elements are
A) Quantified
B) Qualified
C) Feasible
D) Optimal

Accepted Answer

OR provides solution only if the elements are quantified.

Question 8

………. Theory is an important operations research technique to analyze the queuing behaviour.
A) Waiting line
B) Net work
C) Decision
D) Simulation

Accepted Answer

Waiting Line Theory, also known as queuing theory, is specifically designed to analyze and predict the behavior of queues or waiting lines, making it the correct choice for operations research techniques focused on queuing behavior.

Question 9

………… model involves all forms of diagrams
A) iconic
B) mathematical
C) analogue
D) schematic

Accepted Answer

Iconic models involve all forms of diagrams, including pictures, graphs, and charts.

Question 10

. …. Is known as symbolic model
A) Iconic
B) Mathematical
C) Analogue
D) None of the above

Accepted Answer

Mathematical models are known as symbolic models because they use symbols and formulas to represent and analyze the behavior of systems.

Question 11

A map indicates roads, highways, towns and the interrelationship is an ……model
A) Iconic
B) mathematical
C) analogue
D) none of the above

Accepted Answer

An analogue model represents real-world phenomena using physical characteristics or relationships that mimic or correspond to those phenomena, such as a map does with geographic features.

Question 12

………. . is an important Operations research technique to be used for determining optimal allocation of limited resources to meet the given objectives.
A) Waiting line theory
B) Net work analysis
C) Decision analysis
D) Linear programming

Accepted Answer

Linear programming is used for determining the optimal allocation of limited resources to achieve specific objectives.

Question 13

The condition that a system can be in only one state at any point in time is known as
A) Transient state.
B) Absorbent condition.
C) Mutually exclusive condition.
D) Collectively exhaustive condition.

Accepted Answer

The condition that a system can be in only one state at any point in time is known as the mutually exclusive condition. This means that the occurrence of one state prevents the occurrence of another state at the same time, ensuring that no two states can occur simultaneously.

Question 14

At any period n, the state probabilities for the next period n+1 is given by the following formula:
A) n(n+1)=n(n)Pn
B) n(n+1)=n(0)P
C) n(n+1)=(n+1)P
D) n(n+1)=n(n)P

Accepted Answer

The correct formula for updating state probabilities from period n to period n+1 is given by multiplying the state probabilities at period n by the transition probability matrix P, which is represented as n(n+1) = n(n)P. This formula is used in Markov chains to predict future state probabilities based on current probabilities and transition probabilities.

Question 15

If we decide to use Markov analysis to study the transfer of technology,
A) our study will be methodologically flawed.
B) our study will have only limited value because the Markov analysis tells us "what" will happen, but not "why. "
C) we can only study the transitions among three different technologies.
D) only constant changes in the matrix of tr

Accepted Answer

Markov analysis focuses on predicting the probability of various states (in this case, technologies) without explaining the underlying reasons for these transitions. It's a statistical method that can provide insights into what might happen based on current trends, but it doesn't delve into the causal factors behind these changes.
