Answer:
The formation of a linear programming model involves the following steps:
1. Define the objective: Determine what you want to optimize or minimize, such as maximizing profit or minimizing costs.
2. Identify the decision variables: Identify the variables that affect the objective, such as the number of units produced.
3. Formulate the constraints: Establish the limitations that the model needs to operate within, such as production capacity, labor availability, or budget constraints.
4. Write the mathematical equations: Use the identified decision variables, constraints and objective function to write a set of linear equations.
5. Test and solve the model: Test the model by solving the linear equations using mathematical techniques such as simplex method or graphical method.
6. Interpret the results: Analyze the results of the model to gain insights into the optimization of your objective and how changes in variables or constraints can affect the outcome.
