1 Evaluating the Consequences of an Inland Waterway Port Closure with a Dynamic Multiregional Interdependency Model Cameron MacKenzie and Kash Barker School of Industrial Engineering University of Oklahoma Society for Risk Analysis Annual Meeting December 6, 21

2 Motivation 2.5 billion tons of commerce via water annually 2

3 What s new Focusing on inland waterway ports Combining simulation with multiregional input-output model Incorporating companies decision-making process into simulation Integrating publicly available databases for a case study examining effects of closing an Oklahoma port 3

4 Outline 1. Simulation 2. Multiregional Dynamic Inoperability Input- Output Model (DIIM) 3. Port of Catoosa case study 4

5 Simulation + model Port suddenly closes Port officials announce or revise expected opening Each company updates probability of expected opening of port Ship via alternate route? No Commodities not yet shipped flow through port Yes Port opens? No adverse economic effects Multiregional DIIM No Yes 5

6 Ship now or wait for port to open? Premium company willing to pay to ensure on-time delivery Cost of shipping via alternate route Expected penalty cost from waiting Cost of shipping via port 6

7 Ship now or wait for port to open? Cost of shipping via alternate route Premium company willing to pay to ensure on-time delivery Expected penalty cost from waiting Cost of shipping via port 7

8 If company chooses to wait Commodities not exported Effect is equivalent to reducing demand for those commodities Commodities not imported Companies needing those commodities suffer supply shortages Multiregional DIIM Loss of production 8

10 Port of Catoosa case study McClellan-Kerr Arkansas River 2 million tons of cargo 1

11 Transportation hub 3 different rail lines 5 1 trucks per day 11

12 Catoosa daily schedule Create daily schedule of shipments through Catoosa Combine publicly available databases 12

13 Value of products through Catoosa (in millions of dollars) From Okla. To Okla. Total Food and Beverage and Tobacco Products Petroleum and Coal Products Chemical Products Nonmetallic Mineral Products INDUSTRY Primary Metals Fabricated Metal Products Machinery Misc. Manufacturing Ala. 9 9 Ill. 3 3 Kent Louis Miss Tex Ala Ark. 1 1 Ill Iowa 2 2 Louis Miss. 2 2 Ohio Total 13

14 Key assumptions Each shipment < 9 tons (six barges) Railroad is alternate route A little less than 3 times more expensive than barge No capacity constraints 14

15 Results: no penalty Value of product not transported while port is closed Industry Mean Standard deviation Food and beverage and tobacco products 17 7 Petroleum and coal products 8 4 Chemical products 26 1 Nonmetallic mineral products.5.4 Primary metals Fabricated metal products 8 4 Machinery Misc. manufacturing 1 2 Total In millions of dollars Production loss per state due to interdependencies State Mean Standard Deviation Alabama Arkansas Illinois Iowa Kentucky 6 32 Louisiana Mississippi Ohio Oklahoma 2,993 1,449 Texas Total 5,61 2,26 15

21 Conclusions 21 Model Integrating simulation with Multiregional DIIM provides powerful analytical tool Incorporating companies reactive strategies to port closures delivers a more complete picture of consequences Catoosa case study If commodities sit at port, losses around $5 billion If 9% of commodities move before port reopens, losses around $46 million Policymakers may want to incentivize companies to move commodities before port reopens 21
