  2. The Project • Public Transportation Bus 7 Year Bus 10 Year Bus $80,000 $185,000

  3. Bus Descriptions • 10 Year Bus ($185,000) • Freightliner Chassis • CNG Powered • 20 passenger (18 Regular + 2 Wheelchair) • 7 Year Bus ($80,000) • Ford Chassis • Diesel Powered • 20 passenger (18 Regular + 2 Wheelchair)

  4. Assumptions • City is buying a new bus and needs to decide which one is more economical (Fixed output) • Catastrophic engine failure is not included • Both busses will bring in the same amount of profit (customer preference) • Pollution Regulations

  5. 7 yrs bus Salvage value $2,500 Insurance/year $13,200 Maintenance $13,800 Gas cost/year $12,048.44 10 yrs bus Salvage value $4,000 Insurance/year $22,200 Maintenance $27,600 Gas cost/year $11,668.20 Specification

  6. Analysis • MARR (15%) • EUAC (Minimize) • Present Worth of Cost (Minimize) • Maximize Benefit Cost Ratio • Sensitivity Analysis

  7. Analysis • 7 year • EUAC= $58,054 • NPW= $235,784.98 • 20 years • 10 year • EUAC= $95,151 • NPW= $67,491.70

  8. Sensitivity analysis • Maintenance • 10 year has to go up by 370% • Fuel and Maintenance • 7 year has to go up by: • Fuel= 300% • Maintenance = 200% • Tax Incentive • 10 year has to go up by 1,333%

  9. Net Present Worth Analysis

  10. Increase Type 7 Gas Inflation by 6% • Increase Type 7 Gas and Maintenance Consumption by 15%

  11. Conclusion • It seems that the 7 year bus is by far the best choice • It would take a lot for the 10 year bus to be the better choice but for some may be the better choice because of aesthetics

  12. Information Gathering • Internet • Public Transit Agencies (RTA, City of Corona, Foothill Transit) • Private Transportation Companies • Bus Manufacturers
