Basic OR concepts Definition. (A) physical model (B) mathematical model (C) iconic model (D) descriptive model. 71. Thus Operations Research helps in identifying, understanding, analyzing an on-going problem to make a sound decision. Modeling techniques and algorithms are expansively used. To ensure that the volume is accurate, authoritative, accessible and well-written, the chapters are developed by leading experts in each chapter area and written with the students and managers in mind. Basic Business Research Methods. 21. umapathi . Optimization is a branch of OR which uses mathematical techniques such as linear and nonlinear programming to derive values for system variables that will optimize performance. Operations Research is the art of winning wars without actually fighting. – Aurther Clarke.
