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, james.bailey@gatech.edu, 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. 25 - Decision Analytics for Managing Invasive Wild Pigs Matthew Brondum, U.S. Army Corps of Engineers, 3909 Halls Ferry Rd., Vicksburg, MS, 39180, United States of America, matthew.c.brondum@usace.army.mil, Igor Linkov, Zach Collier, Buddy Goatcher 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, chensi@swjtu.edu.cn, 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 Wei-yu Kevin Chiang, City University of Hong Kong, P7614, 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, doonggus@gmail.com, 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, gdlr@gwu.edu 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 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, kfarhat@stanford.edu 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 Cate Fox-lent, US Army Corps of Engineers, 333 Massachusetts Ave 7, Arlington, MA, 02474, United States of America, catherine.fox-lent@usace.army.mil, Matthew Bates, Christy Foran 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, 3150 Sabre Drive, Southlake, TX, 76092, United States of America, dinakar.gade@sabre.com, 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 Erhuan Road, Chengdu, SC, 610031, China, migan@swjtu.cn, Si Chen 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 of Civil & Environmental Eng., 130 Natural Resources Road, Amherst, MA, 01003, United States of America, gonzales@umass.edu, Mahour Rahimi 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, Wuhan, HB, 430074, China, chaocheng@hust.edu.cn, Shiming Deng 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.
