Approach” to Solving Design and Operational Problems That Industrial Engineers Commonly Encounter. In Its Most Basic Form, O.R. May Be Viewed As a Scientific Approach to Solving Problems; It Abstracts the Essential Elements of the Problem into a Model, Which Is Then Analyzed to Yield an Optimal Solution For Implementation.
