Validation/Calibration • Representative data from 2005-2009 • Data from 2008 most complete • Includes all shipments • No description, but weight and volume • Limited vessel data • Personnel data at aggregated level • Batches arriving and leaving Summit
Assumptions • Final destinations at various locations • Can arbitrarily be consolidated • Four vehicle types considered • LC-130, LC-5, Twin Otter, and vessels • Reverse logistics not considered • Our task • No volume constraints • Feasibility of vehicles ‘guessed’
Assumptions • Fuel required only due to personnel • Aggregation level of shipments • Fuel • Personnel • Can be transported by vessel or aircraft • Everything else • Lead time of 30 days for vessel

Front-end Interface • Future expositions in Google Maps • Already implemented them • Manually feeding a solution • Need to integrate with the analytics module • Do not have access to a GIS system
Missing or Incomplete Data • Operating cost of LC-5 and LC-130 • Payload of vessels • Equipment that requires fuel consumption at Summit • Block time between various locations • Baseload daily fuel consumption at Summit • Fuel consumption per person
Missing or Incomplete Data • Special requirements for shipments on particular vehicles • Large equipment can be transported only on particular vehicles • What is the flexibility in terms of the shipment and delivery dates • Flight information available only for Scotia to Summit via Kanger • Need for other locations
Issues and Next Steps Issues Next steps
High Level Understanding of the Model • Available vehicles/modes of transportation • Shipping requirements • Time based (shipping and delivery windows) • Weight and volume • Special attention to fuel • Aggregation from day to week or month
Open Items • Is the delivery date in CST reliable? • Use of traverse in the future • CST considers many additional locations • Transport of fuel and its use at Summit • More granular personnel data • Their flexibility • Duration of stay
Immediate Actions • Settle data issues and requirements • Incorporate reverse logistics • Adjust the model • Gather data • Capture emissions • From transportation • From operations at Summit • As a function of fuel and landings/take-offs
Perpetual Efforts • Modeling future scenarios • How to estimate future shipments? • Not just volume, but also their timing • How many personnel in the future? • Can we anticipate the per month requirement? • Hard to forecast due to limited historical data • Availability of future modes of transportation • Is it going to be the same old story?
Perpetual Efforts • Incorporate KPI • Pounds of cargo moved (O-D) • Number of personnel moved (O-D) • Hourly airlift costs • Ship costs per pound • Volume of fuel consumed for flights and infrastructure • Annual researcher days supported • Energy consumption at Summit
Perpetual Efforts • Incorporate traverse • Handle it as what-if • With or without it • Have cost-benefit analyses • How to model a possible engineering/technological break through?
Future Milestones • On-track
Suggestions • Go-to person at NSF • Anticipated needs of Summit • Understanding of NSF’s mission • Someone from CPS besides Sandy?
Morals • Garbage in, garbage out! • If you can’t measure it, you can’t manage it! • The study will be as good as the data available • We must all be comfortable in all of the assumptions and the team members!
