Operations Research - Study Mode

[#186] What have been constructed for Operations Research problems and methods for solving the models that are available in many cases?
Correct Answer

(C) Mathematical Models

Explanation

Solution: Mathematical Models have been constructed for Operations Research problems and methods for solving the models that are available in many cases. A mathematical model can be defined as a description of a system using mathematical concepts and language to facilitate proper explanation of a system or to study the effects of different components and to make predictions on patterns of behaviour (Abramowitz and Stegun, 1968).

[#187] Which technique is used in finding a solution for optimizing a given objective, such as profit maximization or cost minimization under certain constraints?
Correct Answer

(D) Linear Programming

Explanation

Solution: Linear programming is a mathematical technique for solving constrained maximization and minimization problems when there are many constraints and the objective function to be optimized, as well as the constraints faced, are linear (i.e., can be represented by straight lines).
