already constrained on the use of water. This study aims to examine the impact of
including regeneration possibilities on the flexibility of scheduling procedures and
focuses on trade-offs between cost-optimal and water-efficient production
schedules.
2 - A Layer Analysis Framework to Investigate the CO2 Sinks in the
U.S. Manufacturing Supply Chain Network
Gokhan Egilmez, University of New Haven, Mechanical and
Industrial Engineering, East Haven, CT, 06512, United States of
America, , Mohammad Aslam
In this study, U.S. manufacturing industries and related supply chains are
analyzed from life cycle perspective considering layers in the supply chain. The
focus of the analysis is greenhouse gas (GHG) emissions which are represented
with CO2 equivalent metric. Input output-based life cycle assessment models are
developed and layer analysis is conducted for 6 supply chain layers: onsite,
second, third, fourth, fifth tier suppliers and rest of the supply chain.
3 - Promoting Fair Trade Products

The study considers how to promote fair trade products. We show that
competition between firms increases the usage of fair trade certified raw
materials. We also show that if a fair trade organization can decide the maximum
margin from fair trade products, then it will increase the usage of fair trade
certified raw materials and increase each manufacturer’s total profit compared to
those without consideration of the maximum margin decision.
4 - Effect of Carbon Emission Regulations on the Supply Chain with
Two Substitutable Products

We examine a decision problem for one retailer and one manufacturer under the
influence of carbon tax policy set by the government. The manufacturer produces
two partially substitutable products with different carbon emissions. The two-
stage game theoretical model under three different carbon tax policies is
investigated. The impact of carbon tax and green subsidy on the profits of the
manufacture, the retailer, and the supply chain is analyzed.

1 - Algorithms and Computational Results for the (CITI)
Bike-sharing System

Bike-sharing systems are becoming increasingly prevalent in urban environments.
Users imbalance the system by creating demand in an asymmetric pattern; this
necessitates intervention to restore balance and facilitate future use. Pre-balancing
the system in preparation for usage requires placement of the available bikes at
stations to minimize the expected rush-hour outage minutes. We present
algorithmic approaches for pre-balancing and both mid-rush hour and overnight
rebalancing operations.
2 - The Implications of the Auto Manufacturer’s Involvement
in the Car Sharing Business

We study the auto manufacturer’s choice regarding whether to offer a car sharing
business model in conjunction with the traditional sales channel. We determine
the efficiency of the vehicles offered and we characterize the economic and
environmental implications.

This talk illustrates the use of big-data to capture consumer behavior in Bike-
sahre systems. We then use the estimated patterns of customer to propose system
improvements and redesigns.

1 - Impact of Certification Programs on Waste Recovery
Gokce Esenduran, Yen-Ting Lin,
Wenli Xiao
R2 and E-stewards are two main certification programs for recyclers. The latter is
stricter and costlier to implement; however when customers are “green”, it would
also result in higher product returns. In order to understand which certification is
more profitable to adopt under what conditions, we model the competition
between recyclers considering the consumers’ and collectors’ decisions as well.
We also identify the impact of certification’s stringency on the total recycling
amount.
2 - The Joint Impact of Public Awareness Campaigns and System
Infrastructure on E-Waste Collection
Wenyi Chen, Postdoc, McGill University,

, Jianmai Shi, Vedat Verter
We present a dynamic formulation for the joint design of the collection center
network and the campaign strategy for a monopolistic non-profit organization.
We use a Nerlove-Arrow-type advertising model to capture the “carryover effect”
in the consumers’ environmental awareness and a continuous approach to
incorporate the impact of the collection center locations. A case study based on
the British Columbia Stewardship Program in Canada is presented.
3 - Impact Analysis of Recyclability and Reusability on Greenhouse
Gas Emissions and Related Cost
Hailong Cui, University of Southern California, Marshall School

We build supply chain models to evaluate the impact of recyclability and
reusability on the emissions through the products’ life cycle and derive conditions
that lead to reduction in the long-run average emissions. We then investigate the
cost of recycling and emissions imposed on the supply chain and on the society to
understand optimal decisions for centralized and decentralized cases. We compare
outcomes obtained when recycling is run by the government and when it is done
by the manufacturer.

1 - Dynamic Pricing to Maximize Profits in Multiproduct and
Multioutlet Channel Systems
Markus Bergmeier, Research Assistant, University of Passau /
Chair of Marketing and Services, Innstr. 27, Passau, 94032,
Germany, , Dirk Totzek
To date, operations research approaches have played a minor role in the field of
managing multiple online and offline distribution channels. We develop an
optimization model that captures heterogeneous customer characteristics over
time and enables companies to choose profit-maximizing prices for each product,
distribution channel, intermediary, consumer group, and period. We test this
model using data from different industries and show that it leads to higher profits
and optimal coordination.
