Operations research (OR) is a discipline that applies advanced analytical methods to help make better decisions. OR cases may be applied to a wide range of areas, including:

1. Transportation and logistics: OR is used to optimize transportation and logistics networks, including routing, scheduling, and inventory management.

2. Supply chain management: OR is used to optimize the flow of goods and services through the supply chain, including production planning, inventory control, and distribution.

3. Manufacturing: OR is used to optimize manufacturing processes, including production scheduling, capacity planning, and quality control.

4. Healthcare: OR is used to improve the efficiency and effectiveness of healthcare systems, including hospital management, patient scheduling, and resource allocation.

5. Finance and banking: OR is used to optimize financial operations, including risk management, portfolio optimization, and fraud detection.

6. Marketing and advertising: OR is used to optimize marketing and advertising strategies, including market research, pricing, and media planning as per or case study homework help team.

7.Energy and utilities: OR is used to optimize the production and distribution of energy and utilities, including power grid management, resource allocation, and maintenance scheduling.

8. Agriculture and forestry: OR is used to optimize agricultural and forestry operations, including crop management, forest planning, and supply chain management.

9. Military and defense: OR is used to optimize military operations, including logistics planning, troop deployment, and equipment procurement.

10. Environmental management: OR is used to optimize environmental management practices, including waste management, pollution control, and natural resource management.

These are just some of the areas where OR cases are commonly applied. The scope of OR is constantly expanding as new analytical methods and technologies emerge, making it a growing field of study and practice. 

How one can score good marks in Operation research cases?

Scoring good marks in Operation Research (OR) cases requires a combination of knowledge, skills, and strategies. Here are some tips that can help you achieve success in OR cases:

1.  Understand the problem: The first step in solving an OR case is to understand the problem statement and the objective of the case. Ensure that you are clear about the data, constraints, and assumptions given in the case.

2.  Identify the appropriate method: There are several methods and techniques available in OR, such as linear programming, network analysis, simulation, and decision analysis. Identify the most appropriate method that can be used to solve the case.

3. Apply the method: Apply the chosen method to solve the case. Ensure that you follow the correct steps in the method, such as formulating the model, solving the model, and interpreting the results.

4. Validate the results: Validate the results obtained from the method. Ensure that the results are feasible and make sense in the context of the case is quite important as find out by case study writing help research team.

5.  Communicate effectively: Communicate your solution in a clear and concise manner. Ensure that you explain the problem, methodology, assumptions, and results effectively.

6. Practice: Practice solving different types of OR cases. This will help you improve your problem-solving skills and gain confidence in your abilities.

7. Learn from feedback: Seek feedback from your professors, peers, or professionals in the field. Learn from their feedback and suggestions to improve your performance.

By following these tips, you can improve your ability to solve OR cases and score good marks in your OR assignments and exams. Remember that OR is a dynamic field, and continuous learning and practice are essential to stay updated and excel in this field.
