6. 6 Next Wave Agency Background Specializes in Food for Peace Program Ocean carrier consulting agency Recommends bid prices to carriers

7. 7 Project Introduction Bids based on market knowledge Wanted to develop an analytical method Created a tool to determine bid prices

8. 8 Project Flowchart Optimization Model Carrier Bid Forecasting Supplier Bid Forecasting Analysis User Input Bid Recommendations

9. 9 Project Flowchart Optimization Model Carrier Bid Forecasting Supplier Bid Forecasting Analysis User Input Bid Recommendations

10. 10 Solution Approach: Forecasting Parameters for optimization model Supplier bids Origin ports Commodities Carrier bids

11. 11 Solution Approach: Forecasting Supplier Bids Data available Winning and losing bids for past year Bids are for a commodity at an origin 3,750 pairs 10 suppliers per pair Supplier interaction

12. 12 Solution Approach: Forecasting Supplier Bids Minimum bids for origin-commodity pairs Upward trend Non-seasonal

13. 13 Solution Approach: Forecasting Supplier Bids Double exponential smoothing Non-seasonal data Trend in minimum supplier bids over time Low mean absolute percent error (5.62%)

14. 14 Solution Approach: Forecasting Carrier Bids Data available Past winning carrier bids Past market indices for ocean freight costs Voyage lengths Past voyage factors highly variable Analyze past voyage data 3 carriers 10 vessels

15. 15 Solution Approach: Forecasting Carrier Bids Estimate costs per ton Fuel Daily leasing Port call costs Method considered: Regression High R-squared (87-99.7%) Not adaptable for unusual voyages

16. 16 Solution Approach: Forecasting Carrier Bids Use market costs to estimate profit per ton Past profit per ton fits normal distribution

17. 17 Solution Approach: Forecasting Carrier Bids Method developed Calculate voyage costs using current indices Add random variable for profit per ton Calculate confidence intervals for bid prices Carrier Expected Profit 80% CI90% CI95% CI Maersk 128.70±22.14±28.23±33.64 Sealift 153.80±12.08±15.41±18.36 Liberty 144.80±19.46±24.81±29.56

18. 18 Solution Approach: Forecasting Carrier Bids Houston to Djibouti 20,000 tons Maersk vessel Fuel$29.18 Lease$44.12 Port call$5.00 Total costs per ton $78.30 Add Expected Profit $128.70 Expected Bid Price $207.00

19. 19 Solution Approach: Forecasting Carrier Bids Confidence intervals for expected bid price Expected Bid Price$207.00 80% Confidence Interval(195, 219) 90% Confidence Interval(192, 222) 95% Confidence Interval(189, 225)

21. 21 Project Flowchart Optimization Model Carrier Bid Forecasting Supplier Bid Forecasting Analysis User Input Bid Recommendations

22. 22 Solution Approach: Optimization Simulates USDA’s process of awarding contracts Objective: Minimize total cost Constraints: Carrier quantity Commodity demand Carrier-supplier pairing US vessel priority

23. 23 Solution Approach: Optimization Validated using actual data from 3 past invitations Checked tonnage distribution among carriers Average accuracy for each carrier: 91.7%

24. 24 Solution Approach: Optimization Tested with forecasted supplier bids Change in error: <1%

25. 25 Solution Approach: Optimization Run model multiple times Increment bid prices for Next Wave Analyze results Determine bid prices
