Title: A Perspective on Sustainable Operations

Abstract:   Dr. Toktay will talk about the range of opportunities for our community to define a
comprehensive  research  and  teaching  agenda  in  sustainable  operations.  I  will  combine 
this overview with a recent publication titled “Truthful Mechanisms for Medical Surplus
Allocation.” In  this  paper,  we  analyze  a  resource  allocation  problem  faced  by  Medical 
Surplus  Recovery Organizations  (MSROs)  that  recover  medical  surplus  products  to  fulfill 
the  needs  of  under- served healthcare facilities in developing countries. Due to the uncertain,
uncontrollable supply and limited information about recipient needs, delivering the right product
to the right recipient in  MSRO  supply  chains  is  particularly  challenging.  The  objective  of
 this  study  is  to  identify strategies to improve MSROs' value provision capability. In
particular, we propose a mechanism design approach, and determine which recipient to serve at each
shipping opportunity based on recipients'  reported  preference  rankings  of  different  products.
 We  find  that  when  MSRO inventory information is shared with recipients, the only truthful
mechanism is random selection among recipients, which defeats the purpose of eliciting information.
Consequently, we propose two operational strategies to improve MSROs' value provision: i) not
sharing MSRO inventory information  with  recipients;  and  ii)  withholding  information 
regarding  other  recipients.  We characterize  the  set  of  truthful  mechanisms  under  each 
setting,  and  show  that  eliminating inventory and competitor information provision both improve
MSROs' value provision. Further, we  investigate  the  value  of  cardinal  mechanisms  where 
recipients  report  their  valuations.  We show that in our setting, eliciting valuations has no
value added beyond eliciting rankings under a  wide  class  of  implementable  mechanisms. 
Finally,  we  present  a  calibrated  numerical  study based on historical data from a partner
MSRO, and show that a strategy consisting of a ranking- based  mechanism  in  conjunction  with 
eliminating  inventory  and  competitor  information  can significantly improve MSROs' value provision.
