Scientific Method for making decisions in Operation Research

classification of modelling in operations research, quantitative techniques of operation research models, characteristics or features of a good model in operation research, approaches and phases of operation research in decision making

Scientific Method in Operation Research:

Since the main objective of operation research is to provide better quantitative information for making decisions, now our aim is to learn how we can have better decisions.

The scientific method in OR for making decisions generally involves the following phases:

(I) Judgment Phase includes:

(i) Determination of operation.

(ii) Determination of objectives.

(iii) Determination of the effectiveness of measures.

(iv) Lastly, the formulation of the problems relative to the objectives.

(II) Research Phase utilizes:

(i) Observation and data collection for a better understanding of the problem.

(ii) Formulation of relevant hypotheses and models.

(iii) Analysis of available information and verification of hypothesis.

(iv) Predictions of various results from the hypothesis, generalization of the result and consideration of alternative methods.

(III) Action Phase:

(i) Recommendations for remedial action to those who first posed the problem, this includes the assumptions made, scope and limitations, alternative courses of action and their effect.

(ii) Putting the solution to work: implementation.
