What are the steps of modeling in Operations Research?

Modeling in Operations Research typically involves several key steps:

1. Problem Definition: Clearly identify and define the problem that needs to be solved, including objectives and constraints.
2. Model Formulation: Develop a mathematical representation of the problem, which often includes variables, equations, and inequalities that encapsulate the relationships among different components.
3. Solution Techniques: Apply appropriate methods or algorithms to solve the formulated model, which may include optimization techniques, simulations, or heuristics.
4. Validation and Implementation: Verify the model's accuracy and applicability to the real-world situation, followed by implementing the solution and monitoring its effectiveness.
