  1. Marine Highway Freight SystemModeling Effort Update CSC Advanced Marine 15 June 2010

  2. Objective • Provide Model for evaluating potential Marine Highway Routes • Key Features • Reusable “Toolset” for others w/o programming experience • Relative comparison with Trucking Routes • Able to model ship operator’s process or track cargo unit to final destination • Primary metrics: time, throughput, & cost • Secondary metrics: fuel consumption, pollutant output

  3. Progress • Model Framework • Inputs & Outputs • Model Architecture • Basic Example

  4. Model Framework • Model will be created in ExtendSim 7 Discrete Event Modeling software • Uses Hierarchical Blocks - designed for “toolset” implementation • Readily imports data from Excel – simplifies data input for user • Models feasibility of marine highway route over extended time period • Basic Framework is three block types: • Creation block • Travel block • Port (cargo transfer) block • Data Inputs • Specific to block type • User defined data • Supports Monte Carlo simulation – captures real world variability

  5. Input & Output Capabilities • Input: • Cargo time distribution at departure port • Ship departure schedule • Port specific ship loading/unloading times • Ship capacity and performance characteristics • Ship route specifics • Truck and route characteristics • Output: • Cargo time distribution at destination • Ship fuel consumption • Delays at each stage • Emissions Tracking • Cost Tracking

  6. Block Development • Depending on complexity of process and available data, modeling fidelity can be varied by selecting interchangeable blocks

  7. Creation Block • Creates cargo/truck items • Specifies distribution of when blocks arrive at port or distribution center • Specifies truck performance characteristics • Creates ship items • Specifies ship performance characteristics

  8. Travel Block • Calculates the time delay of traveling ship or truck • Basic block will calculate time delay based on speed ÷ distance • Intermediate block will use speed limits • Advanced block will be route specific and will use GMU or Rutgers defined time delays based on time of day

  9. Port Block • Simulates marrying of ships with cargo • Basic block accommodates varying number of ship loading and cargo staging areas • Intermediate block will increase cargo loading fidelity • Advanced block will model the exact process and time delays of a specific port • Will accommodate logic for both RoRo and LoLo • Will function as an intermediate port

  10. DES Example Layout • Models route from General Foam Plastics in Portsmouth, VA to a Costco distribution center in Jamesburg, NJ.

  11. Departure Port

  12. Ship Travel

  13. Arrival Port

  14. Summary • Framework Development On Track • Implementation of Metrics going well • Desire feedback on selection of primary & secondary metrics • Data collection contingent on guidance from advisory board and participation of industry partners
