• 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.
• 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
