11
The operations Research technique which helps in minimizing total waiting and service costs is.
Discuss
Answer & Solution
Answer: Option A
Solution:
The operations Research technique which helps in minimizing total waiting and service costs is Queuing Theory. Queuing theory (or "queueing theory") examines every component of waiting in line to be served, including the arrival process, service process, number of servers, number of system places, and the number of customers—which might be people, data packets, cars, etc.
12
Linear programming is a.
Discuss
Answer & Solution
Answer: Option D
Solution:
Linear programming is a Constrained optimization technique, Technique for economic allocation of limited resources and Mathematical technique.
13
A constraint in an LP model restricts.
Discuss
Answer & Solution
Answer: Option D
Solution:
A constraint in an LP model restricts value of objective function, value of a decision variable and use of the available resources.
14
The distinguishing feature of an LP model is.
Discuss
Answer & Solution
Answer: Option A
Solution:
The distinguishing feature of an LP model is relationship among all variables is linear. The linear programming model is an algebraic description of the objective to be minimized and the constraints to be satisfied by the variables.
15
Constraints in an LP model represents.
Discuss
Answer & Solution
Answer: Option D
Solution:
Constraints in an LP model represents Limitations, Requirements and Balancing limitations & requirements.
16
Non-negativity condition is an important component of LP model because.
Discuss
Answer & Solution
Answer: Option B
Solution:
Non-negativity condition is an important component of LP model because value of variables make sense & correspond to real-world problems. Non-negativity restriction indicates that all decision variables must take on values equal to or greater than zero.
17
Before formulating a formal LP model, it is better to.
Discuss
Answer & Solution
Answer: Option D
Solution:
Before formulating a formal LP model, it is better to Express each constrain in words, Express the objective function in words and Verbally identify decision variables.
18
Maximization of objective function in an LP model means.
Discuss
Answer & Solution
Answer: Option A
Solution:
Maximization of objective function in an LP model means Value occurs at allowable set of decisions. Linear programming refers to choosing the best alternative from the available alternatives, whose objective function and constraint function can be expressed as linear mathematical functions.
19
Which of the following is not a characteristic of the LP model?
Discuss
Answer & Solution
Answer: Option B
Solution:
An objective function of maximization type is not a characteristic of the LP model. The objective of linear programming is to: “maximize or to minimize some numerical value.
20
The best use of linear programming technique is to find an optimal use of.
Discuss
Answer & Solution
Answer: Option D
Solution:
The best use of linear programming technique is to find an optimal use of Money, Manpower and Machine.
