3 - Channel Choice For Closed-loop Supply Chain Under
Government Replacement-subsidy

This paper considered government replacement-subsidy policy to examine the
channel choice of remanufacturer consisting of a single manufacturer and a single
remanufacturer. Based on the replacement-subsidy and carbon emission, we
constructed two CLSL channel models which the remanufacturer may cooperate
or compete with the manufacturer through different channels. Then, we
discussed the impacts of the replacement-subsidy on the channel choice decision
of remanufacturer and profits of CLSC system and its members by the method of
game theory. At last, the numerical analysis was adopted to emulate the optimal
price, optimal quantity and emission quantity of each channel.

Responsible sourcing is of increasing research interest. But what happens if your
customer is not socially responsible? We examine the impact of the 2015 VW
diesel emissions scandal on automotive suppliers.
2 - The Role Of Managerial Commitment On The Relationship
Between Controversy And Environmental Practice Adoption
Rick Hardcopf, University of Minnesota,
The adoption of environmental management practices (EMPs) intended to reduce
a firm’s environmental footprint has increased steadily over the years. EMPs are
also positively related to superior environmental, financial, and operational
performance. But while the general drivers of EMP adoption have been evaluated
extensively, no empirical research has evaluated whether a negative
environmental event, such as an environmental spill or pollution event, impacts a
firm’s pattern of EMP adoption. We evaluate this relationship, and the moderating
effect of managerial commitment, using a novel secondary dataset derived from
10k filings, sustainability reports, and other public sources.
3 - The Relationship Between Corporate Social Performance,
Productivity, Financial Performance, And Risk

We employ DEA-based measures for productivity and corporate social
performance to examine their relationship with multiple dimensions of financial
performance and risk. We test our hypotheses in a panel that comprises 476 firms
in nine US manufacturing industries during the period 1999-2009.
4 - Relationship Between Appointments Of Corporate Sustainability
Leaders And Firm Performance

With an increasing significance of sustainability as a corporate goal, firms have
been establishing new positions in their top management teams - positions that
we collectively term as Corporate Sustainability Leaders (CSLs). We empirically
examine whether and under what conditions does the stock market react to
announcements of CSL appointments. While we find that CSL appointments are
overall value-neutral, interestingly, we find that under certain conditions, the
stock market reaction is significantly more positive. Our findings evidence
nuances in the market reactions to the various categories of announcements of
CSL appointments considered in our work.

1 - Sensitivity Analysis as a Tool For Improving Robustness Of
Underground Mine Production Schedule
Tacio Vinicius Ferreira Lopes, South Dakota School of Mining and
Technology, 501 E Saint Joseph Street, Rapid City, SD, 57701,

Andrea Brickey
Underground mine production scheduling has long been a manual and time-
consuming task performed by mining engineers. Recent research has shown that
an integer programming formulation can be used to determine a large-scale
underground mine production schedule. We perform sensitivity analysis of an
underground mine production schedule model and the results are used in
determining a more robust and operationally implementable schedule.
2 - Optimal Support Pillar Placement In An Underground Mine
Levente Sipeki, Colorado School of Mines,
We determine support pillar placement for a top-down one-stope retreat mining
operation to maximize the profit from ore extraction, subject to constrains on
pillar stress, hydraulic radius, pillar length-to-width rations, and stope-to-pillar
extraction rations depending on level depth. A heuristic produces a pillar
placement design that increases the extraction capacity of the mine by (1) shifting
the pillars to find the most profitable stopes to extract, (2) allowing less ore to be
used as a pillar and (3) reducing the total cost of stope slotting by creating fewer
pillars.
3 - Short And Medium-term Scheduling Model For Large
Underground Mines
Louis-Pierre Campeau, PhD Student, Polytechnique Montreal,
2900 Edouard-Montpetit, Montreal, QC, H3T 1J4, Canada,
, Michel Gamache
Applications of operations research to short-term underground mine scheduling
are very few, mostly because of the complexity and specificity of its constraints.
This presentation will discuss the advances made with a model for short- and
medium-term scheduling in large underground mines. The results of the model
application to real-world and fictional datasets will also be explained. Comment
on future work and possibilities in this field will conclude the presentation.
4 - Underground Mine Plan Optimization
David Whittle, University of Melbourne, a, Melbourne, Australia,
We present a new approach to the optimization of the design of an underground
mine. Our algorithm determines the design and selection of stopes, the network
of horizontal development and the selection of levels, in order to maximize
undiscounted cashflows. In solving the mine planning problem we have devised a
new method to solve the Node-Weighted Geometric Steiner Tree problem, which
has potential applications in other fields.

1 - An Integrated Fleet Management Model Introducing Alternative
Fuel Trucks
Ilke Bakir, PhD Candidate, Georgia Institute of Technology,
Atlanta, GA, United States, , Alan Erera
We generalize a fleet replacement problem in long-haul trucking by considering
some infrastructural and operational decisions alongside with fleet replacement
decisions. We propose an integrated fleet management model designed to be
particularly helpful in situations where new truck types (alternative fuel trucks,
as the main focus) are being introduced into existing fleet. To demonstrate the
benefits of utilizing this computationally challenging model instead of simpler
methods, we present a comparative computational study. Later, to ease the
computational burden of solving this problem, we propose a Benders’
decomposition framework.
