My Subject : Operational Research

=Operations Research= Operations Research, a new science,popularly called as O.R.,was developed in 1940's during the world war II , when the military management involved scientists from various streams to help them find strategies to improvise their military projects. Operations Research is the scientific, statistical and logical approach to problem solving. It involves MATHEMATICAL MODELS to solve the complex decision problems in order to choose the best or optimum option among many.

Brief Overview
A Mathematical model is one in which a mathematical equation representing a real system is shown using constants and variables. These models are abstract and precise. They can be classified as : are models in which its parameters and the relationship among them is known with certainity. or stochastic models are models in which one or more parameter is not known with certainty.
 * Deterministic Models
 * Probabilistic Models

Applications of O.R.
=Reliability= The term Reliability is a symbol of quality as perceived by the user. For a car, reliability is seen as its failure-free operation, for a software program, reliability is seen as its error-free execution and so on. Defined by many authors,reliability of a system is the probability of failure-free operation of the system for a given time-period under the conditions of intended use.
