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.
Models in Operation Research
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.
Iconic or physical models
Analogue or schematic model
Symbolic or mathematical model.
4) By nature of the environment
5) By extent of generality
6) By time of horizons
CHARACTERISTICS OF GOOD MODEL
System environmental changes.
Adaptable to parametric type.
Easy and economical to construct
PHASES OF OPERATION RESEARCH
A) determination of operation
B)establishment of objective and values.
C)determination of suitable measures.
D)formulation of problems.
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
