Answer to Question #237062 in Operations Research for opr

Question

State and explain the operations research techniques.

Answer 1

The principal techniques in implementing Operation Research in practice include the following:

(1) Definition of the problem

(2) Construction of the model

(3) Solution of the model

(4) Validation of the model

(5) Implementation of the solution

(1) Definition of the problem: This involves describing the scope of the problem under investigation, with the aim of identifying three principal elements of the decision problem: description of the decision alternatives, determination of the objective of the study, and specification of the limitations under which the modeled system operates.

(2) Construction of the model: This entails an attempt to translate the problem definition into mathematical relationships, ensuring that the resulting models fits one of the standard mathematical models, such as linear programming, reaching a solution by using available algorithms.

(3) Solutions of the model: This is by far the simplest of all the OR techniques because it entails the use of well-defined optimization algorithms.

(4) Validation of the model: This checks whether or not the proposed model does what it purports to do, that is, does it adequately predict the behavior of the system under study?

(5) Implementation of the solution: Implementation of the solution of a validated model involves the translation of the results into understandable operating instructions to be issued to the people who will administer the recommended system.
