Question 1

Operations research is the application of methods to arrive at the optimal solutions to the problems.
A)Economical
B)Scientific
C)Both A and B
D)Artistic

Accepted Answer

Operations research uses scientific methods to determine the optimal solutions to complex problems, focusing on analytical and mathematical techniques rather than economic or artistic approaches.

Question 2

In operations research, the are prepared for situations.
A)Mathematical models
B)Physical models diagrammatic
C)Diagrammatic models
D)Both B and C

Accepted Answer

Mathematical models are used to represent real-world situations in a simplified and abstract way. They can be used to analyze and solve problems in a variety of areas, including operations research.

Question 3

OR can evaluate only the effects of .
A)Personnel factors
B)Financial factors
C)Numeric and quantifiable factors
D)Both A and B

Accepted Answer

Operations Research (OR) is a discipline that deals with the application of advanced analytical methods to help make better decisions. It is capable of evaluating not just personnel or financial factors, but any factors that can be quantified or expressed numerically. This includes a wide range of considerations, from logistics and supply chain issues to scheduling, resource allocation, and beyond.

Question 4

Which technique is used in finding a solution for optimizing a given objective, such as profit maximization or cost reduction under certain constraints?
A)Qualing theory
B)Waiting Line
C)Both A and B
D)Linear Programming

Accepted Answer

Linear Programming is a mathematical technique used for optimizing a given objective, such as maximizing profit or minimizing cost, subject to certain constraints.

Question 5

By constructing models, the problems in libraries increase and cannot be solved.

Accepted Answer

Constructing models in libraries helps in organizing, managing, and solving problems by providing structured approaches and solutions.

Question 6

A solution can be extracted from a model either by
A)Conducting experiments on it
B)Mathematical analysis
C)Both A and B
D)Diversified Technique

Accepted Answer

Solutions can be extracted from a model through both conducting experiments on it and mathematical analysis. These methods allow for understanding and predicting the behavior of the model under various conditions.

Question 7

The main limitation of operations research is that it often ignores the human element in the production process.

Accepted Answer

Operations research primarily focuses on mathematical models and quantitative analysis to solve complex problems, often overlooking the human factors such as employee morale, skills, and resistance to change, which can significantly impact the production process and outcomes.

Question 8

Feasible solution satisfies
A)Only constraints
B)only non- negative
C)Both A and B
D)A, B and optimal solution

Accepted Answer

A feasible solution in the context of optimization problems satisfies all the constraints of the problem as well as adheres to the non-negativity restrictions (if any). This means it must meet all the specified conditions (constraints) of the problem and cannot have negative values for variables that are defined to be non-negative. The concept of an optimal solution is separate; a feasible solution is not necessarily optimal.

Question 9

What is the objective function in linear programming problems?
A)A constraint for available resource
B)An objective for research and development of a company
C)A linear function in an optimization problem
D)A set of non- negativity conditions

Accepted Answer

The objective function in linear programming problems is a linear function that needs to be optimized (either maximized or minimized) subject to a set of constraints.
