24 - Stable Strategic Marriages
James Bailey, Graduate Student, Georgia Institute of Technology,
116 Ponce De Leon Ave NE, Atlanta, GA, 30308, United States of
America, Craig Tovey
The effect of lying on the stability of marriages is a long standing open problem.
When men and women behave strategically, an ideal decision mechanism selects
a marriage that is (1) stable, and (2) egalitarian, with respect to sincere
preferences. We provide a positive result to (1) and a negative result to (2) under
two natural conditions. We strengthen current results about the Gale-Shapley
algorithm, showing that the woman-optimal marriage is the only obtainable one
when men propose.

Wild pigs pose significant environmental, economic, and social risks to the United
States and around the world. A number of wild pig eradication and control
measures exist, but many eradication campaigns are ultimately unsuccessful due
to a variety of complexities across multiple domains. We are developing a decision
analytic tool which will assist affected landowners in deciding which eradication
technique best suits their site-specific interests.
26 - The Regional Logistics Hubs Location Problem Based on the
Topsis and Genetic Algorithm: A Case of Sichuan
Si Chen, Southwest Jiaotong University, #1 Jingqu Road, Emei,
China, , Qian Guo, Mi Gan
The regional logistics demands, which are the key factors for logistics hubs
location problem, are changing with the developing regional economic and the
structure of industry. Then we aim to modeling this problem with an integrated
approach of multi-criteria decision making and integer programming model. And
the real data case of Sichuan is employed to verify the feasibility of proposed
models and approach. Moreover, the numerical results are corresponding to the
actual logistics situation.
27 - Promotional Mix and Pricing Strategy with Risk-averse Buyers in
the Age of Social Media

How should a firm minimize the wastage on marketing expenditure with an
efficient promotional mix? The firm has two promotional strategies, hype
advertising campaign (HAC), which refers to a basic publicity that makes
consumers aware of the product’s existence, and referral reward program (RRP),
which refers to an incentive-based program that offers rewards to the existing
buyers for bringing in new buyers. We study the firm’s optimal promotional mix
and pricing strategy with risk-averse buyers.
28 - A Game Theoretic Analysis of Electricity Time-of-use (TOU)
Tariff for Residential Customers
Dong Gu Choi, Senior Researcher, Korea Institute of Energy
Research, 152 Gajeong-ro, Yuseong-gu, Daejeon, 34129, Korea,
Republic of, , Valerie Thomas
We properly formulate a game-theoretic model for analyzing not only the optimal
behaviors of both an electric utility and residential customers but also their
monetary gains or losses under a TOU tariff. With two heterogeneous customer
types in terms of consumption pattern, we identify that a win-win situation is not
possible. Also, we emphasize our analytic results by describing a numerical
example, and we discuss the implications of our results for electric utilities and
regulatory agencies.
29 - Why Classical Hybrids are so Risky for Entrepreneurs,
and What to do About it
Gaston De Los Reyes, Assistant Professor, George Washington
University School of Business, 2201 G St. NW, Funger 615,
Washington, DC, 20008, United States of America,
Williamson (1991) insufficiently characterized the institutions of hybrid
governance, emphasizing forms that feature neoclassical devices to co-govern past
contract close. Entrepreneurs, however, frequently resort to hybrids of classical
form, lacking terms to protect from ‘lawful’ opportunism in case of disruption. I
explicate the implications, drawing upon my dissertation study of contract law. I
discuss a novel institutional solution and managerial strategies for the status quo.
30 - An Integrated Make-pack-route Problem of Fresh Agri-food
Online Retailing in China
Mu Du, Institute of Systems Engineering, Dalian University of
Technology, No.2 Linggong Road, Dalian, China,
, Xiangpei Hu, Nan Kong
Fresh agri-food sold by farm-to-home online retail is produced through a make-
pack-route process at farm’s distribution centers. Due to the large variety of
produce and high cost of intermediate storage, an integrated decision model is
employed to coordinate these different operations. We introduce a make-pack-
route model that minimizes the total cost and propose an effective heuristic
method. We report a case study based on real-world business practice in China.
31 - Decision Analytic Modeling of the Five Competitive Forces
in the Residential Solar Industry
Karim Farhat, PhD Candidate, Management Science and
Engineering, Stanford University, 475 Via Ortega,
Huang Engineering Center 245A, Stanford, CA, 94305,
United States of America,
Using a first-of-kind quantitative decision-analytic model of Michael Porter’s five
competitive forces, we investigate an international solar firm’s plan to enter and
properly position in the US residential solar PV industry. Applying a Bayesian
probabilistic approach, the model assesses the uncertain profitability of the overall
competitive market, and it provides several insights on the firm’s go-to-market
strategy, including: regional focus, vertical integration, and customer finance.
32 - Portfolio Analysis for Army Corps of Engineers Business
Line Integration

Portfolio analysis is used to demonstrate opportunities to leverage synergies across
business lines. Coastal systems can benefit from reduced cost, reduced
environmental impact, or increased project performance when planning for
Navigation, Environmental Restoration, and Coastal Storm Risk Management
projects is intentionally integrated. Long-term monitoring to improve
quantification of project interactions can lead to improved utility of this type of
analysis.
33 - Incorporating Passenger Recovery Decisions During Airline
Operations Recovery
Dinakar Gade, Senior Operations Research, Sabre,

America, , Sureshan Karichery,
Shahram Shahinpour
Airlines are faced with several types of disruptions that impede regular
operations. The Sabre AirCentre Recovery Manager (Ops) helps airlines quickly
recover both the schedule and aircraft rotations from disruptions. We introduce a
new feature of Recovery Manager called the Passenger Flow Module (PFM) that
incorporates passenger re-accommodation decisions during schedule recovery.
The solutions generated reduce the impact to passenger flows in the network and
reduce passenger inconvenience.
34 - The Impact of Roadway Traffic Flow in Regional Network
Design Problem
Mi Gan, Dr, Southwest Jiaotong University, 111 N 2nd Bound

In order to solving the problem that the existed logistics network design
models(LND) are lack of consider on roadway traffic flow. The uncover degree
function of logistics facility nodes based on impedance function was constructed.
Then, integrated logistics network design models and corresponding algorithms
were proposed with the basis of uncover degree function. The comparison of
general LND models and models we developed by real case reveals the impact of
roadway traffic flow on LND.
35 - Evaluating Zoning Strategies for Demand Responsive
Transit Systems
Eric Gonzales, University of Massachusetts, Amherst, Department

DRT systems often divide their service area into smaller regions in order to
simplify operations. However, this management strategy can create inefficiencies.
This paper develops an analytical formulation to explain the relation between
agency cost and zoning strategies. The two main objectives are to understand
when a service area needs to be divided into smaller regions to reduce the total
costs of a DRT system and how the split should be done in order to be the most
cost effective.
36 - Supply Enhancement in Capital-constraint Assembly System:
Financing Suppliers or Dual Sourcing?
Chaocheng Gu, PhD Candidate, Huazhong University of Science
and Technolgy, 1037 Luoyu Rd., 326 School of Management,

we study two mechanisms for supply reliability enhancement in capital constraint
assembly system. Financial mechanism. Three financial strategies are examined;
that is, bank finance, buyer finance and a combined peer finance. The
manufacturer can also avail of a more expensive backup sourcing. When bank
finance and buyer
finance both present, the manufacturer always prefer buyer finance.The optimal
mechanism switches back and forth as the equilibrium order quantity increases.
