Operational research is a subject that studies how to make the best decision with limited resources. Learning operations research requires some knowledge of mathematics, statistics and computer science. Here are some suggestions to help you learn operations research better:

1. Learn basic concepts: First of all, you need to understand the basic concepts of operational research, such as linear programming, integer programming, dynamic programming, graph theory, network flow and so on. These concepts are the basis of understanding operational research.

2. Learn mathematics and statistics: operational research involves a lot of mathematical and statistical knowledge, such as linear algebra, calculus, probability theory, stochastic processes, etc. You need to master this knowledge to better understand the models and methods of operational research.

3. Learning programming languages: Operational research usually needs to use computer programs to solve practical problems. Therefore, learn one or more programming languages (such as Python, R, C++, etc. ) is very important for learning operations research.

4. Learn modeling skills: an important aspect of operational research is modeling. Learning how to abstract practical problems into mathematical models and how to solve these models by mathematical methods is the key to learning operational research.

5. Hands-on practice: Learning operational research through practical problems is a very effective method. You can take part in some courses or competitions related to operational research, or try to apply operational research methods to solve practical problems in the laboratory or work.

6. Read relevant books and papers: Reading professional books, teaching materials and papers about operational research can help you understand the knowledge and application of operational research more deeply. This will help you improve your theoretical level and practical operation ability.

7. Join academic groups and social networks: Joining academic groups and social networks related to operational research allows you to communicate with other researchers and practitioners and learn about the latest research results and development trends. This will help you keep your enthusiasm and motivation for operational research.

8. Seek guidance and help: It is normal to encounter difficulties and problems in the learning process. Don't be afraid to seek guidance and help from others, such as asking teachers, participating in study groups or online discussions. This can help you solve problems faster and improve your learning effect.
