2 - Role of Alternative Payment Models in Incentivizing Information
Sharing in Healthcare

School of Management, Richardson, TX, 75080, United States of
America, Srinivasan Raghunathan,

We explore the incentive alignment problem for electronic sharing of health
information (HIE) under episode and performance-based payments. In particular,
we study what quality improvement provisions should be embedded into the
payments and which of the specific performance incentives associated with
alternative payment models; rewards, penalty, or a combination of the two better
aligns the incentives for HIE adoption.
3 - Design of Multi-stage Services with Diagnostic Tasks

Business, Carnegie Mellon University, 5000 Forbes Avenue,

Many services require diagnostic tasks, e.g., diagnostic testing in an emergency
room. The time spent on these tasks and the sequence in which they are
performed is usually discretionary. We explore how discretionary diagnostic tasks
should be distributed among different stages of a multi-stage operations system to
deliver high quality service with minimum wait cost. We are interested in
situations where the extent of information gained from diagnostic tasks varies
across different stages.
4 - Coordinating Product Support Supply Chains under
Outcome-based Compensations
Dong Li, Singapore University of Technology and Design, 8

We look at contracting between an OEM and a supplier, where the supplier
manufactures the part, and the OEM assembles the final product and manages
product availability for the customer under an outcome-based contract. We find
that wholesale price contracts and repair cost sharing contracts cause under-
investment in failure reduction effort and over-investment in service capacity.
Penalty sharing contracts can achieve the first best solution and coordinate the
supply chain.

1 - The Effect of Cyber Attack on Customers’ Purchase and Channel
Choice Behavior

This paper examines the effect of data breach announcement on customer
shopping behavior in terms of spending level, frequency of shopping trips and
channel migration. By using actual customer transaction data from a
multichannel retailer and exploiting a natural experiment, we find that the
cyberattack announcement leads to a 22.5% decrease in sales and a 14.1%
decrease in shopping trips made by customers. Also, we find that customers tend
to migrate to channels that were not breached.
2 - Learning about Customer Preferences from Clickstream Data
Dorothee Honhon, Associate Professor, University of Texas at
Dallas, 800 W. Campbell Road, Richardson, TX, 75080,
United States of America,
We study the problem of an e-tailer who learns about consumer preferences from
observing sales or clickstream data in a Bayesian fashion. The e-tailer decides
which products to display on the search page and which products are available for
purchase. We show that in some cases, it may be optimal to display products
which are not purchasable so as to learn about consumer preferences.
3 - Optimal Replenishment in the Presence of Phantom Inventories
using Point-of-sales Data

We study how inventory managers can fully utilize point-of-sales (POS) data for
the design of replenishment strategies that account for the existence of phantom
inventories. We show that even though the optimal replenishment timing in the
presence of phantom inventories is complex in nature, there is a simple policy
that performs very close to optimally, and provides the same recommendation as
the optimal policy for a vast majority of scenarios.
4 - Impact of Tabletop Technology on Restaurant Performance
Fangyun (Tom) Tan, Assistant Professor, Cox Business School,
SMU, 6212 Bishop Blvd, Dallas, TX, 75275, United States of
America, Serguei Netessine
We analyze a large data set of transactions in a casual restaurant chain to
understand the effect of implementing a tabletop technology on service
performance (measured in sales and meal duration). We find the technology
directly increases sales and significant reduces the meal duration. We provide
insights on how to manage technology in restaurant operations.

1 - A Data-driven Approach to Designing Service Concepts for
Vehicle Operations Management
Min-Jun Kim, PhD Student, POSTECH, Engineering Building #4-
316, Pohang, 790-784, Korea, Republic of,
Kwang-jae Kim, Chie-Hyeon Lim
This talk proposes a data-driven approach to designing service concepts for
vehicle operations management (VOM). The proposed approach first collects
VOM-related data through various sensors installed on vehicles, analyzes the data
to extract insights regarding vehicle operations, and then designs service concepts
to support the operation of vehicles. This talk also presents case studies on
passenger and commercial vehicles.
