To convince you that your city, county, state needs to participate in the RSS Analysis Project.

It’s free!


What do you get?◦ A comparison of some different ways to run your

RSS◦ A detailed analysis of the most promising way

What do you have to do? ◦ Not much◦ Fill out a questionnaire with data that you already

have


Analyze RSS operations in 36 jurisdictions Test RSS performance in standard scenario Evaluate operational alternatives Select the best operational approach and

perform detailed analysis◦ Performance◦ Robustness◦ Cost

Develop understanding of “RSS physics” Identify rules of thumb, best practices

We’ve completed about 20 analyses and we’ve seen a lot◦ Delivery by dump truck◦ An RSS in an airplane hangar◦ Drive-through PODs◦ Mega-PODs for 1,000,000◦ A mini-POD at every neighborhood school◦ Ferry boats◦ State delivery to county warehouses

RSS is the critical link in supply chain connecting Federal materiel and PODs

RSS Goal—assure uninterrupted supply of materiel to PODs

Smooth RSS operations are essential to effective bioterror response

RSS operations difficult to plan and manage

Complexity increases with◦ Larger number of PODs◦ Wide variation in POD sizes◦ Larger geography◦ Long drive times, traffic◦ Shorter operational window◦ Longer and/or later receiving window◦ Limited resources: crews, docks, trucks◦ Mixed-capacity truck fleet

Slack◦ “Breathing room”◦ Ability to ship early

POD Interruption◦ Negative slack late delivery◦ How many regimens are delayed?

Other metrics◦ RSS floorspace (square feet occupied)◦ Dock utilization◦ Truck utilization◦ Miles traveled

How many deliveries per POD? Which trucks should you use? How many pallets do you put on a truck?

Each alternative requires its own route system
