3 - A Nonlinear Programming Approach For Determining A General
Equilibrium For N-person Games
Ahmad Nahhas, Gradiate Researcj Associate I, University of Texas
at Arlington, 706 W Mitchell Cir Apt 621, Arlington, TX, 76013,
United States, , H. W. Corley
A general equilibrium for n-person normal form games is a set of mixed strategies
with the following property. No player in some subset B of all players can achieve
a better payoff if players in an associated proper subset G of all players change
strategies unilaterally. A nonlinear programming approach is presented to prove
the existence of such an equilibrium and then compute one.
4 - Stability Analysis Of Horizontal Mergers In A Market With
Asymmetric Substitutability

We consider the stability of horizontal mergers between firms in a Cournot
oligopoly in which the substitutability of goods is asymmetric. We specifically
focus on the core allocation under the grand coalition in a general N-firm
oligopoly. The main result of our analysis shows that the grand coalition is stable
in a highly asymmetric market in terms of substitutability.
5 - Applying Game Theory To Multiobjective
Multistakeholder Decisions
Edward Cook, Senior Vice President, Capital One, 4 Bisley Court,
Henrico, VA, 23238, United States,
For Multi-Objective Decision Analysis (MODA) when the decision-makers grow
past one, there is difficulty. Often one decision-maker’s process impacts another.
To solve this, the application of Game Theory to model the objectives can be used.
Game Theory models the interaction between multiple players enabling discovery
of the Pareto Equilibrium and not just a Nash Equilibrium which may be
suboptimal.

1 - Network Characteristics And Supply Chain Disruption Resilience
Yuhong Li, Virginia Tech, Blacksburg, VA, United States,
, Christopher Zobel, Onur Seref
Previous studies on supply chain network resilience focus on network types,
which cannot describe a real supply chain network well. Hence, we focus on
characteristic level in this study. This work aims to show what combinations of
characteristics will make the supply network more resilient, and we expect to
provide executable prescriptions to practitioners to improve supply chain
resilience. Classification methods and simulations are employed to carry out this
study.
2 - Supply Chain Cooperation In Enterprise Platform
Transformation Strategies
Lyu Gaoyan, PhD, Guanghua School of Peking University, Beijing,
China,
With rapid development, the Internet has changed the traditional supply chain
structure and is creating new business models and the way of enterprise
management. Based on the background of Chinese market, we study the
transformation of supply chain platform strategy considering the attitudes of
decision makers in different supply chain stages. Using the revenue sharing
contract, we obtain the pareto improvement interval. By solving the equilibrium
of the platform innovation cooperation strategies, we find the innovation
cooperation strategy between the supplier and the platform retailer and provide
the profit allocation method of the full-cooperation strategy.
3 - Optimal Product Design And End-of-Life Options For an OEM
Under Different Pricing Strategies
Jie Zhang, PhD Student, Virginia Tech, 852 Claytor Square,
Blacksburg, VA, 24060, United States,
The design of a product impacts its production cost, salvage value, and demand.
In this paper, a novel two-stage model pertaining to the reverse supply chain of
an original equipment manufacturer (OEM) and containing the impact of product
design, is formulated. We first and foremost give demand function under different
pricing strategies of new and remanufactured products. Then, optimal prices and
optimal end-of-life options are derived. All the possible cases are analyzed and
graphed under different market and cost parameters. By considering different
pricing strategies and proportion of green market demand at the second stage, we
generate insights pertaining to optimal product design strategies. Finally, we
determine optimal product design strategies for the OEM.
4 - Quantifying The Benefits Of Continuous Replenishment Program
For Partner Selection

This research develops a data-driven model that quantifies the benefits of a
continuous replenishment program (CRP). CRP is a well-established supply chain
collaboration program that has been used widely in various business sectors. The
proposed model is able to compute the cost savings of CRP for both partners and
at three levels of inventory holding, transportation and ordering cost components.
The model is adopted by a major healthcare manufacturer who seeks to estimate
the cost savings of a business relationship with a major distributor. The results
indicate that CRP reduces the total cost of supply chain by 19.1% where the
distributor gains disproportionately more savings.
5 - The Newsvendor Problem Re-visited With Novel
Funding Schemes
Emre Berk, Bilkent University, Faculty of Business Administration,
Ankara, 06533, Turkey,
Recently novel funding mechanisms have emerged for new or small businesses
which have limited access to traditional financing and credit mechanisms. These
provide unique opportunities and challenges for operational decision making. In
this talk, we revisit the newsvendor problem under such novel financing schemes
and discuss some operational implications and issues.

1 - Two-stage Supply Chain With Product Substitution From Different
Carbon Emissions And Government Intervention
Wang Chuanxu, Dean, Shanghai Maritime University, 1550
Haigang Ave, Shanghai, 201306, China,
The two stage supply chain consisting of one retailer and one manufacturer is
considered, in which manufacturer produce two substitutable items with different
carbon emissions. Government levies carbon emissions tax on the production of
high carbon item and offer subsidies on the production of low carbon item.The
profits of manufacturer and retailer as well as the social benefit of government are
compared under the three situations.A numerical example is given to
demonstrate the effectiveness of propose models and analyze the impact of
market share for high carbon item, manufacturing cost coefficient for low carbon
product and green cost coefficient for high carbon item on the decision results.
2 - A Study On The Effect Of Life-skills Improvement With
Team-based Learning In Operations Management
Sungyong Choi, Assistant Professor, Yonsei University, College of
Government and Business, 1 Yoneseidae-gil, Wonju, 26493, Korea,
Republic of,
The purpose of this study is to show that my Operations Management class help
students improve their life skills in a semester. I designed my class more
interactively by introducing a well-known approach of team-based learning, but
the detailed ideas of class management were developed by my own careful
considerations. Then, I defined the students’ life skills as problem solving and self-
directed learning. Finally, at the end of the semester, the levels of the life skills in
each student had been improved significantly compared with the levels at the
beginning of the semester.
3 - Log-linear Analysis Of Moral Duties Of Transformative Leadership
Feng Xu, Georgia Southwestern State University, School of
Business Administration, 800 GSW State University Drive,
Americus, GA, 31709, United States,
Recent development in transformative leadership theories focuses on studying the
duties of leaders. Applying log-linear model towards the survey data, this paper
presents that there exists positive relationship between moral development stages
and the ethical focus of the perspectives of transformative leadership. The findings
can help both scholars and practitioners to understand more completely the
relationship between effective leadership and leaders’ moral duties, and help
leaders retain trust and increase commitment within an organization.
