Excel record of integer programming optimization model to solve the problem

Title:

1. First, extract information according to the requirements of the question, and list the mathematical model:

Two, solve the answer through "Solver" in Excel:

1. Create a data table:

2. Set the data according to the mathematical model:

Maximum Value: =B7*B2+C7*C2+D7*D2+E7*E2

Constraints: =B7*B3+C7*C3+D7*D3+E7*E3

3. Use the Solver function to solve:

Set the goal: To set the position for a formula (which we just wrote) at A10 in the table;
Set the variable cells: the selected number of four cells, because in the mathematical modelThey add constraints for variables;
: add according to two formulas in the mathematical model:

i. All variables are integers:

ii. Constraint (total weight) less than or equal to 50:

After all are added, this is the interface——

Then click Solve:

The maximum value and the quantity of each item are known.
Click "OK" to keep the calculated value.

This completes the task.
