  1. 1. OPERATION RESEARCH APARNA G. KHAPRE JENNY RAUT Guided by Ashish tqma2z.blogspot.com
  2. 2. CHARACTERISTICS OF OPERATION RESEARCH <ul><li>System (executive) orientations. </li></ul><ul><li>The use of interdisciplinary team. </li></ul><ul><li>Application for scientific method. </li></ul><ul><li>Uncovering of new problems. </li></ul><ul><li>Improving in the quality of decisions </li></ul><ul><li>Use of computers. </li></ul><ul><li>Quantitative solutions. </li></ul><ul><li>Human factors. </li></ul>
  3. 3. Models in Operation Research <ul><li>Definition: </li></ul><ul><li>A model as used in operation research ,is defined as an idealized representation of the real life situation. </li></ul><ul><li>It represents one or a few aspects of reality. </li></ul><ul><li>Diverse items such as a map a multiple activity charts, an autobiography,PERT,network,breakeven equation,balance sheet etc are all models because each of them represents a few aspects of real life situation. </li></ul>
  4. 4. CLASSIFICATION SCHEMES OF MODELS - <ul><li>The various schemes by which models can be classified as- </li></ul><ul><li>By degree of abstraction. </li></ul><ul><li>By function </li></ul><ul><li>By structure </li></ul><ul><li>Iconic or physical models </li></ul><ul><li>Analogue or schematic model </li></ul><ul><li>Symbolic or mathematical model. </li></ul>
  5. 5. <ul><li>4) By nature of the environment </li></ul><ul><li>Deterministic model </li></ul><ul><li>Probabilistic model </li></ul><ul><li>5) By extent of generality </li></ul><ul><li>General model </li></ul><ul><li>Specific model </li></ul><ul><li>6) By time of horizons </li></ul><ul><li>a)Static horizon </li></ul><ul><li>b)Dynamic horizon </li></ul>
  6. 6. CHARACTERISTICS OF GOOD MODEL <ul><li>Simplifying assumputions. </li></ul><ul><li>Relevant variables. </li></ul><ul><li>System environmental changes. </li></ul><ul><li>Adaptable to parametric type. </li></ul><ul><li>Easy and economical to construct </li></ul>
  7. 7. PHASES OF OPERATION RESEARCH <ul><li>1)Judgement phase </li></ul><ul><li>A) determination of operation </li></ul><ul><li>B)establishment of objective and values. </li></ul><ul><li>C)determination of suitable measures. </li></ul><ul><li>D)formulation of problems. </li></ul>
  8. 8. RESEARCH PHASE <ul><li>a)Operation and data collection. </li></ul><ul><li>b)Formulation of hypothesis and models </li></ul><ul><li>c)Observation and experimentation to test hypothesis. </li></ul>
  9. 9. d)Analysis of available information and verification. e)Predictions of various results from the hypothesis f)Generalization of results and consideration. 3)Action phase
