5 - Shipping To Time-sensitive Customers With Competing Carriers Tao Lu, Erasmus University,o applRotterdam, Netherlands, lutao0927@hotmail.com, Ying-Ju Chen, Jan C Fransoo, Chung-Yee Lee We consider a shipper selling a kind of products to a destination market where customers obtain higher utility if they receive the product earlier but their time- sensitivity is heterogeneous. Two carriers provide transportation services with different speeds, and compete by quoting freight rates. By splitting shipments between carriers, the shipper may enjoy the benefit of product differentiation through selling early-arrived products at a premium price. However, driven by the underlying trade-off between product differentiation and competition, we show that product differentiation via dual-mode shipping may be inferior to simply restricting to a single shipping mode. MA72 Bass- Omni Supply Chain Mgt V Contributed Session Chair: Youran Fu, University of Pennsylvania, 3730 Walnut Street, Room 532, Philadelphia, PA, 19104, United States, youranfu@wharton.upenn.edu 1 - Coordinating A Textile Supply Chain In Post Multi Fibre Agreement Era: A Developing Economy Perspective The abolishment of the Multi Fibre Agreement (MFA) in 2005 opened up a plethora of export opportunities of textile and cotton for the textile supply chain of many developing economy countries such as India and China. On the other hand, it leads to a shortage of low-cost raw material in these countries and affects the apparel production. In this context, we adopt a realistic three-level structure to represent the textile supply chain of a developing economy country and focus on designing appropriate coordination mechanisms using cost sharing and revenue sharing contracts. 2 - Coordination And Competition In A Supply Chain: Franchise Contract And Facility Sharing Contract Tulika Mukherjee, Postdoctoral Fellow, Concordia University, 1455 Boulevard de Maisonneuve, Montreal, QC, H3G 1M8, Canada, jum.tulika@gmail.com A two-suppliers-one-retailer supply chain model is developed for a marketing channel where all the partners either compete or collaborate to enhance their profit. Competitive and collaborative strategies under franchise contract and facility sharing contract are analysed with a game theoretic lens. Finally, a comprehensive computational analysis is carried out to validate our model. 3 - How Prominence Effect & Repeated Channel Interactions Can Lead To Slotting Allowances Yourann Fu, University of Pennsylvania, 3730 Walnut Street, Room 532, Philadelphia, PA, 19104, United States, youranfu@wharton.upenn.edu, JiaqiconfliXu, Gerard P Cachon We develop a supply chain model in which the retailer owns two types of shelf space - a prominent and an inconspicuous shelf space. We show that under this setting, slotting allowances can arise even in the absence of retailer competition as the result of collusion between manufacturers when there is repeated channel interaction. We discuss implications of the retailer’s sales effort and shelf space values on channel coordination. MA79 Legends G- Omni Health Care, Modeling V Contributed Session Chair: Erin Garcia, Graduate Student, Georgia Institute of Technology, 755 Ferst Drive, Atlanta, GA, 30332, United States, egarcia3@gatech.edu 1 - Analysis Of Blood Banking System Operations At The Time Of Low Demand Amir H. Masoumi, Assistant Professor of Management, Manhattan College, 4513 Manhattan College Parkway, Bronx, NY, 10471, United States, amir.masoumi@manhattan.edu, Min Yu We investigate a new trend of demand for human blood which has significantly affected the operations of blood banks in the US over the past few years. Using a supply chain network optimization model, we analyze the effectiveness of the changes made to such systems including downsizing of operations, closure of facilities, as well as mergers and acquisitions.

2 - Reducing Operating Room Time In Robotic Surgery Using Simulation Yueran Zhuo, University of Massachusetts Amherst, 121 Presidents Drive, Amherst, MA, 01003, United States, yzhuo@som.umass.edu, Senay Solak Robotic surgery procedures differ from classical surgeries due to the reduced role that the surgeon plays during the operation. In order to study potential performance improvement options in this increasingly common type of surgery, we build a simulation model based on data collected from several urogynecology robotic surgery cases. The model is then used to assess the value of several alternative process improvement ideas aimed at reducing operating room time. 3 - Scheduling Multidisciplinary Cancer Clinics Anne G. Leeftink, University of Twente, Enschede, Netherlands, a.g.leeftink@utwente.nl, Ingrid M. Vliegen, Erwin Hans Many hospitals start multidisciplinary clinics to assure timely care. Their planning requires an open access approach. The number and timing of regular appointments influences the performance for the open access patients. Furthermore, since the appointment schedule of the first physician determines the referral rate to the other clinicians, the timing of the open access slots influences the waiting time as well. This study’s objective is to jointly develop a blueprint appointment schedule for all clinicians. Since this can only be analytically solved for small problem instances, we developed a novel local search heuristic to handle real-life instances, which we applied to a real life case study. 4 - Seasonal Variations In Spatial Access To Pediatric Asthma Treatment Across The US Erin Garcia, Graduate Student, Georgia Institute of Technology, 755 Ferst Drive, Atlanta, GA, 30332, United States, egarcia3@gatech.edu Asthma is a chronic condition that affects over 7 million children in the US, many of whom will have a preventable severe health outcome due to their asthma. Disease control is as important as underlying severity for a child’s health, and is directly related to the quality of the medical care received. Geographic access to care varies by state, provider type, and patient insurance status. This work uses Medicaid Claims data to analyze the seasonal variations in both available provider capacity and patient demand for asthma visits to understand their impact on the health outcomes of asthmatic children. We also propose interventions to decrease seasonal variations and improve access to care year round. Chair: Libo Sun, PhD Student, University of Science and Technology of China, 96# Jinzhai Road, Hefei, Anhui, PR China, Hefei, 230026, China, libosun@mail.ustc.edu.cn 1 - Mindfulness Effect On Technology Acceptance Process In The Context Of Bounded Rationality Emine Erdogan, PhD Candidate, Rutgers The State University of New Jersey, Newark, NJ, 07102, United States, ee134@scarletmail.rutgers.edu This study investigates how decision making processes in accepting a new technology have been influenced by consumers’ mindfulness. Based on the theory of bounded rationality and TAM, the study will propose the concept of “bounded mindfulness”and will measure it by testing the effects of ambiguity, and time pressure related to the consumers acceptance of high tech vehicles. Previous research suggests that mindfulness can be described by alertness, awareness, and openness to novelty and negatively correlated with heuristic processing. Moving from this, the paper aims to investigate the impact of consumer mindfulness on information processing and its consequences in high tech vehicles adoption . 2 - Considering Customer Representatives’ Risk Preference: Acquisition And Retention Delegation Strategies Under The Spoiling Effect Yi Liao, Professor, Southwestern University of Finance and Economics, 425 Mount Prospect Avenue, 404, Newark, NJ, 07104, United States, yiliaoswufe@gmail.com In this study, we focus on the spoiling effect and use the discrepancies between customer acquisition and retention efforts to capture how the spoiling effect influences customer demand. We compare firms’ performance using the following three strategies: the delegation of acquisition model, in which customer acquisition is delegated to customer representatives; the delegation of retention model, in which customer retention is delegated to customer representatives; and the total delegation model, in which both tasks are delegated to customer representatives. Our main finding is that the spoiling effect significantly affects acquisition and retention efforts and firm profitability. MA86 GIbson Board Room-Omni Marketing I Contributed Session
