INTRODUCTION
OVERVIEW OF OPERATION RESEARCH
Now a day Operations research has been applying by every large organization in developed nation and developing country in every department at all level. Availability of faster and flexible computing facilities and the number of qualified OR professionals have enhanced the acceptance and popularity of the discipline. In the country like USA and the UK growth of OR has not been limited, now it has reached to many countries including India.
Operational research encompasses a wide range of problem-solving techniques and methods applied in the detection of improved decision-making and efficiency Leachman et al (2013). Some of the tools used by operational researchers are statistics, optimization, probability theory, queuing theory, game theory, graph theory, decision analysis, mathematical modeling and simulation. Because of the computational nature of these fields, OR also has strong ties to science.
Application work in operational research, like other engineering and economics’ disciplines, attempts to use models to make a practical impact on real-world problems.
