# Operation Research Books

The Books and Study materials for the first year engineering are now updated on the official website. We have updated several books on various subjects of Engineering. Candidates can choose the books they want and prepare for the examination. In this article, we are focusing on the subject of Operation Research. Operations research (OR) is a scientific method of problem-solving and decision-making that is beneficial in the management of organizations.

# Operation Research Books 2018

In a nutshell, operations research is the method of applying advanced analytical techniques to help make healthier decisions. By using procedures such as mathematical mmodelling to analyze complicated situations, operations research gives officials the power to make more powerful choices and build more productive systems based on:

• More complete data
• Consideration of all available options
• Careful predictions of outcomes and estimates of risk
• The latest decision tools and techniques

Here, we are giving you the best books and Study materials so that you will face no difficulty in the examination. We are offering the detailed syllabus of the subject so that you can prepare according to that. Candidates can use these books for their studying process, so it will be easy for them to understand.

# Operation Research Syllabus- B.Tech Elective

OBJECTIVE:
• Identify and develop operational research models from the verbal description of the real system.
• Understand the mathematical tools that are needed to solve optimization problems.
• Use mathematical software to solve the proposed models.
