1 - Design Of Sales Compensation Schemes To Reduce
Product Waste
Arzum Akkas, Boston University,
Sahoo Nachiketa
We investigate sales-force compensation schemes that can alleviate product
expiration driven by over-selling in retail supply chains. Using sales commission
data from a consumer packaged goods manufacturer, we recommend parameters
for a compensation scheme based on our structural model of sales-force selling
behavior.
2 - Extended Warranties And Secondary Market Strategies
Wayne Fu, Georgia Institute of Technology, Atlanta, GA,
United States, Atalay Atasu,

We investigate the implications of extended warranties in a durable goods market
from both producer and environmental perspectives. Considering a product
subjected to failure, offering extended warranties helps an OEM increase the
value-added of its products, but implies repair costs and cannibalization from its
secondary market. In this context, we formulate a stylized durable goods model
that explores the interaction between the OEM’s warranty offerings and buy-back
programs (to reduce secondary market cannibalization). We find that the choice
of warranty offering is surprising non-monotonic in product failure and that
secondary market interference influences the choice significantly.
3 - Sustainable Urban Water Management
Buket Avci, Singapore Management University, Singapore,
Singapore, Onur Boyabatli
Climate change, escalating costs and other risks are causing cities to face ever-
increasing difficulties in efficiently managing scarcer and less reliable water
resources. We develop a stylized analytical model that captures the salient
features of urban water management by modeling different demand classes
(domestic vs. industrial) and supply processes (rainwater catchment, reclaimed
water and desalination).
4 - Re-manufacturability And Investment Planning

We consider a monopolist manufacturer who produces a single-branded product
and uses a mix of virgin and recycled materials in its production. The
manufacturer can invest in either upstream or downstream technologies or both
to improve recyclability/re-manufacturability and to reduce recycling costs
respectively. We investigate profit maximizing investment strategies in presence of
green consumers.

1 - Why And How Do Consumers Discount Remanufactured
Products?
James Duane Abbey, Texas A&M University, 4217 TAMU, College
Station, TX, 77843-4217, United States, ,
Rainer Kleber, Gilvan Souza, Guido Voigt
We empirically isolate the impact of quality concerns on consumers’ willingness
to pay (WTP) and the likelihood to purchase remanufactured products. Perceived
risk, in the form of quality defects and cosmetic defects, has a significant impact
on WTP, even after controlling for the WTP for new products, and other
attributes.
2 - Coopeting For Green Product Development
Karthik Murali, University of Alabama, Tuscaloosa,
We study the impact of collaboration between supply chain partners and
coopetition between supply chains on the level of investment in green product
design and development and its ensuing implications to society and the
environment. We also address the role of policy makers in stimulating such
partnerships between organizations.
3 - Designing Sustainable Products Under Co-production Technology
Shouqiang Wang, Clemson University, 131D Sirrine Hall, Clemson,
SC, 29634, United States, Yen-Ting
(Daniel) Lin, Haoying Sun
We consider a firm who utilizes co-production technology to introduce a green
product with raw material that would be otherwise discarded. Some consumers
value resource savings achieved by green product while others do not. We
examine impact of resource scarcity, technology feasibility, consumers’ greenness
on firm’s profitability and environmental impact.

1 - Personalized Diabetes Management Using Electronic Medical
Records
Alexander M Weinstein, Massachusetts Institute of Technology,
Cambridge, MA, United States, Dimitris
Bertsimas, Nathan Kallus, Ying Zhuo
Current clinical guidelines for managing type 2 diabetes do not differentiate based
on patient-specific factors. We present a data-driven algorithm for personalized
diabetes management using a k-nearest neighbor approach. Using electronic
medical records for 10,806 type 2 diabetes patients from Boston Medical Center,
we evaluated the effect of the algorithm’s recommendations on matched patient
outcomes from unseen data. The personalized approach yielded substantial
improvements in glycated hemoglobin outcomes relative to the standard of care.
The algorithm’s evidence-based recommendations can be summarized for
providers in an intuitive, interactive dashboard.
2 - A Template Matching Approach To Comparing Hospital Quality In
An Integrated Health Care System
Wenqi Hu, Columbia Business School, New York, NY, United
States, , Carri Chan, Jose Zubizarreta,
Gabriel Escobar
There is a growing interest from healthcare providers and policymakers to better
measure and improve quality of hospital care. Commonly used risk adjustment
models can be inconsistent measures of hospital quality and do not enable a clear
understanding of the potential impact of unobservable risk factors on hospital
rankings. This work applies a new template matching approach to define a
reference population over which 21 hospitals within an integrated healthcare
system are compared. This approach enables more transparent comparisons than
prior approaches. We further quantify the influence of hospital operational factors
on patient outcomes for performance improvement considerations.
3 - A Room With A View: An Econometric Analysis Of How Facility
Layout Impacts Care Provision In The Emergency Department
Lesley Meng, Doctoral Candidate, The Wharton School, University
of Pennsylvania, 3730 Walnut Street, Suite 500 JMHH,

, Robert Batt, Christian Terwiesch
The hospital emergency department (ED) has frequently been used to study the
dynamics of service operations and how such operations adapt to fluctuations in
workload. We study how the facility layout of ED patient rooms impacts nurse
workflow decisions. Specifically, our dataset is comprised of infrared nurse
location tracking data from a large urban teaching hospital over a study period of
six consecutive months in 2013. In linking this to room occupancy patient data,
we are able to investigate potential facility layout variables, such as distance from
the nurses’ station, that impacts the patient’s length of stay in the ED through
variation in the amount of nurse attention received.
