5 - Shipping To Time-sensitive Customers With Competing Carriers

We consider a shipper selling a kind of products to a destination market where
customers obtain higher utility if they receive the product earlier but their time-
sensitivity is heterogeneous. Two carriers provide transportation services with
different speeds, and compete by quoting freight rates. By splitting shipments
between carriers, the shipper may enjoy the benefit of product differentiation
through selling early-arrived products at a premium price. However, driven by
the underlying trade-off between product differentiation and competition, we
show that product differentiation via dual-mode shipping may be inferior to
simply restricting to a single shipping mode.

1 - Coordinating A Textile Supply Chain In Post Multi Fibre
Agreement Era: A Developing Economy Perspective

, Arnab Adhikari, Badrifrom mNarayanan
The abolishment of the Multi Fibre Agreement (MFA) in 2005 opened up a
plethora of export opportunities of textile and cotton for the textile supply chain
of many developing economy countries such as India and China. On the other
hand, it leads to a shortage of low-cost raw material in these countries and affects
the apparel production. In this context, we adopt a realistic three-level structure
to represent the textile supply chain of a developing economy country and focus
on designing appropriate coordination mechanisms using cost sharing and
revenue sharing contracts.
2 - Coordination And Competition In A Supply Chain: Franchise
Contract And Facility Sharing Contract
Tulika Mukherjee, Postdoctoral Fellow, Concordia University, 1455
Boulevard de Maisonneuve, Montreal, QC, H3G 1M8, Canada,
A two-suppliers-one-retailer supply chain model is developed for a marketing
channel where all the partners either compete or collaborate to enhance their
profit. Competitive and collaborative strategies under franchise contract and
facility sharing contract are analysed with a game theoretic lens. Finally, a
comprehensive computational analysis is carried out to validate our model.
3 - How Prominence Effect & Repeated Channel Interactions Can
Lead To Slotting Allowances
Yourann Fu, University of Pennsylvania, 3730 Walnut Street,
Room 532, Philadelphia, PA, 19104, United States,
JiaqiconfliXu, Gerard P Cachon
We develop a supply chain model in which the retailer owns two types of shelf
space - a prominent and an inconspicuous shelf space. We show that under this
setting, slotting allowances can arise even in the absence of retailer competition as
the result of collusion between manufacturers when there is repeated channel
interaction. We discuss implications of the retailer’s sales effort and shelf space
values on channel coordination.

1 - Analysis Of Blood Banking System Operations At The Time Of
Low Demand
Amir H. Masoumi, Assistant Professor of Management, Manhattan
College, 4513 Manhattan College Parkway, Bronx, NY, 10471,
United States, , Min Yu
We investigate a new trend of demand for human blood which has significantly
affected the operations of blood banks in the US over the past few years. Using a
supply chain network optimization model, we analyze the effectiveness of the
changes made to such systems including downsizing of operations, closure of
facilities, as well as mergers and acquisitions.
2 - Reducing Operating Room Time In Robotic Surgery
Using Simulation
Yueran Zhuo, University of Massachusetts Amherst,

, Senay Solak
Robotic surgery procedures differ from classical surgeries due to the reduced role
that the surgeon plays during the operation. In order to study potential
performance improvement options in this increasingly common type of surgery,
we build a simulation model based on data collected from several urogynecology
robotic surgery cases. The model is then used to assess the value of several
alternative process improvement ideas aimed at reducing operating room time.
3 - Scheduling Multidisciplinary Cancer Clinics
Anne G. Leeftink, University of Twente, Enschede, Netherlands,
Ingrid M. Vliegen, Erwin Hans
Many hospitals start multidisciplinary clinics to assure timely care. Their planning
requires an open access approach. The number and timing of regular
appointments influences the performance for the open access patients.
Furthermore, since the appointment schedule of the first physician determines
the referral rate to the other clinicians, the timing of the open access slots
influences the waiting time as well.
This study’s objective is to jointly develop a blueprint appointment schedule for
all clinicians. Since this can only be analytically solved for small problem
instances, we developed a novel local search heuristic to handle real-life
instances, which we applied to a real life case study.
4 - Seasonal Variations In Spatial Access To Pediatric Asthma
Treatment Across The US
Erin Garcia, Graduate Student, Georgia Institute of Technology,
755 Ferst Drive, Atlanta, GA, 30332, United States,
Asthma is a chronic condition that affects over 7 million children in the US, many
of whom will have a preventable severe health outcome due to their asthma.
Disease control is as important as underlying severity for a child’s health, and is
directly related to the quality of the medical care received. Geographic access to
care varies by state, provider type, and patient insurance status. This work uses
Medicaid Claims data to analyze the seasonal variations in both available provider
capacity and patient demand for asthma visits to understand their impact on the
health outcomes of asthmatic children. We also propose interventions to decrease
seasonal variations and improve access to care year round.

1 - Mindfulness Effect On Technology Acceptance Process In The
Context Of Bounded Rationality
Emine Erdogan, PhD Candidate, Rutgers The State University of
New Jersey, Newark, NJ, 07102, United States,
This study investigates how decision making processes in accepting a new
technology have been influenced by consumers’ mindfulness. Based on the
theory of bounded rationality and TAM, the study will propose the concept of
“bounded mindfulness”and will measure it by testing the effects of ambiguity, and
time pressure related to the consumers acceptance of high tech vehicles. Previous
research suggests that mindfulness can be described by alertness, awareness, and
openness to novelty and negatively correlated with heuristic processing. Moving
from this, the paper aims to investigate the impact of consumer mindfulness on
information processing and its consequences in high tech vehicles adoption .
2 - Considering Customer Representatives’ Risk Preference:
Acquisition And Retention Delegation Strategies Under The
Spoiling Effect
Yi Liao, Professor, Southwestern University of Finance and
Economics, 425 Mount Prospect Avenue, 404, Newark, NJ, 07104,
United States,
In this study, we focus on the spoiling effect and use the discrepancies between
customer acquisition and retention efforts to capture how the spoiling effect
influences customer demand. We compare firms’ performance using the following
three strategies: the delegation of acquisition model, in which customer
acquisition is delegated to customer representatives; the delegation of retention
model, in which customer retention is delegated to customer representatives; and
the total delegation model, in which both tasks are delegated to customer
representatives. Our main finding is that the spoiling effect significantly affects
acquisition and retention efforts and firm profitability.
