B&R Oil and Gas maintains many waste disposal tanks to serve sites across 20 counties as noted in the figure below (should look familiar). Each tank needs to serve production sites either from the residing county or from the adjacent counties. Please respond to the logistics management questions below.

Provide a thorough analysis that explains the result set from the Excel run. The analysis should provide each process (step) through the analysis including: 1. Identify the objective variable and explain what it means. 2. Identify the decision variables and explain each. 3. Create and provide the objective function. 4. Determine and note all of the constraints for each county and find the counties identified with the minimum number based on the objective function. 5. What is the minimum number of disposal tanks needed to cover all 20 counties and note which counties are those?
