UNHRD Network
- 5 United Nations Humanitarian Response Depots (UNHRDs)
- Over 1,000 SKUs
- Over 5 million emergency relief items
- Stockpiles owned by over 50 humanitarian organizations

- Deployment of humanitarian relief items to TAPs
- Food and cooking supplies
- Water and water purification equipment
- Sanitation equipment
- Shelter and blankets
- Medical supplies
- Etc.
Research Objectives
May 22-23, 2013 MIT SCM ResearchFest 5
- Build a model to minimize response times
- Prescribe where items should be placed
- Evaluate the inventory capacity to respond to a typical disaster
(Photos: wfp.org)
UNHRD stockpiles can serve what expected percentage of people affected by a large disaster? What is the expected time to deploy a certain type of relief item?
Agenda
- Background on humanitarian response
- Research objectives
- Development of LP model and datasets

xij: inventory to be deployed from depot, i, to disaster site, j cij: delivery time between depot, i, and disaster site, j pk: probability of disaster scenario, k, occurring
Dataset #1: Demand
- Filtered disaster records from 2008 to 2012
- Includes natural and manmade disasters
- Does not include epidemics, industrial accidents
- Size
- 852 demand scenarios
β TAP and location
May 22-23, 2013 MIT SCM ResearchFest 8 website: www.emdat.be
Dataset #2: Delivery Times
- Classified disasters into EM-DATβs 23 disaster sub-regions
- Measured 115 (5x23) βas-the-crow-fliesβ arcs
- Converted distances to times, assuming 500 mph
- Example: Accra to the Caribbean
May 22-23, 2013 MIT SCM ResearchFest 9
5,225 miles =10.4 hours
Dataset #3: Supply

Item
- Blankets
- Buckets
- Jerry cans
- Kitchen sets
- Latrine plates
- Mosquito nets
- Soap bars
website: www.hrdlab.eu
Example: Blanket Conversion (2 per family of 5)
- 164,624 units in inventory
- 411,560 units of capita inventory (CI)
Applying the Model
- Understand how CI affects the optimal pre-positioning of
inventory
- Keep demand scenarios and delivery times constant
- Change initial CI from one to over 25 million units
- See which depots the model uses and assess why
- Measure the expected response capacity of the 7 selected
UNHRD items
- Percentage of people the item serves
- Time to deliver the items

Insights
- Depot importance
- Optimal number
- Order of usage
- Ideal response capacity
- Diminishing marginal returns at different CI levels
- Inventory capacity
- 8-23% potential time savings
