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