HERMES can address… • Impact of introducing new technology • e.g., vaccines, storage, and monitoring • Characteristics of vaccines and other technologies • e.g., vaccine vial size, vaccine thermostability, cold device capacity • Configuration and operations of the supply chain • e.g., storage, shipping frequency, personnel, ordering policy • Effects of differing conditions/circumstances • e.g., power outages, delays, inclement weather, limited access • Investment or allocation of resources • e.g., adding refrigerators vs. increasing transport frequency • Optimizing vaccine delivery • e.g., minimize cost, cost per outcome, maximize immunizations

Steps to Model Supply Chains • Identify purpose of simulation • Questions to address • Perspective of user • Determine level of detail required in the simulation model • Less detail to address general, simpler questions • More detail to address more complex questions For more information visit- http://hermes.psc.edu
Steps to Model Supply Chains • Gather and input supply chain data into HERMES • Evaluate the data that is available. • Less data less detailed simulation model • More data more detailed simulation model • Decision maker can directly run HERMES on any laptop computer For more information visit- http://hermes.psc.edu
HERMES GUI • Simplifies • Data input • Running models • Evaluating different scenarios • Identifying bottlenecks • Seeking Beta testers for the HERMES GUI for early 2014 For more information visit- http://hermes.psc.edu

Benin: The Problem 1 http://www.who.int/immunization_monitoring/data/ben.pdf- 2011 Government and WHO-UNICEF estimate. • The Benin supply chain may not be effectively getting vaccines to the population. • At least 15% of children in Benin are not receiving full vaccinations (as measured by estimated DTP3 coverage).1 • Impending new vaccine introduction (e.g., rotavirus vaccine) may exacerbate this problem. • The Benin vaccine supply chain may also cost more to operate than it should (not completely efficient).

Benin: Objectives • Evaluate the current Benin vaccine supply chain: • Identify vulnerabilities (bottlenecks) • Calculate operating costs (storage, transport, labor, and building) • Assess Benin vaccine supply chain’s ability to handle new vaccine introduction. • Identify an alternate, more efficient vaccine supply chain design. • Establish a blueprint for redesign. • Build a business case to change the system. • Determine if costs could be lowered and coverage increased from the current system.
Approach: HERMES Modeling Each Scenario Data on Benin Vaccine Supply Chain • 2010 Cold Chain Equipment Management (CCEM) assessment • Pilot 2012 EVM+HERMES • 2008 Comprehensive Multiyear Plan (cMYP) • Personal communications with Benin Ministry of Health (MoH), WHO, UNICEF, Project OPTIMIZE, and other key stakeholders Detailed Simulation Model of the Benin Vaccine Supply Chain Run Simulation Measure Vaccine Availability Measure Operating Costs Measure Capital Expenditure Make Additions to Relieve Bottlenecks Run Simulation Measure Vaccine Availability Measure Operating Costs For more information visit- http://hermes.psc.edu
Current System: Not Completely Effective or Efficient Vaccine availability:93% (71% after rotavirus introduction) Total annual operating costs:$1,113,954 ($1,117,494 after rotavirus introduction) Logistics cost per dose: $0.23($0.26 after rotavirus introduction) * Current Bottlenecks: Storage at National Store and transport between all levels
Capital Expenditures Required to Achieve Each Design Alternative that will Accommodate Rotavirus Introduction
ZS + Truck Loops: Lowest Capital Expenditures and Operating Costs
ZS + Truck Loops: Lowest Logistics Cost per Dose Administered
ZS+Truck Loops: Over Half a Million USD in Cost Savings after 5 Years
Conclusions • Zone Sanitaire plus 4 x 4 Truck Loops at Lowest Level is clear choice. • Lower capital expenditures • Lower operating costs • After four years over half-million in cost savings • Combination of Zone Sanitaire and Truck Loops leads to a synergistic effect.

Summary and Discussion • HERMES can rapidly create a simulation model of any supply chain • Serve as a virtual laboratory to help a wide variety of vaccine decision makers answer any number of questions • Already implemented in multiple countries For more information visit- http://hermes.psc.edu
Looking To The Future • Over the next ten years most GAVI countries are expanding their vaccines • MenAfriVac®, Rotavirus, PCV-13, others • Many new vaccines are relatively large • Even more burden on the vaccine cold chain • Higher coverage rate targets for current and new vaccines • Cost effective distribution is critical to achieve coverage targets For more information visit- http://hermes.psc.edu
