INFORMS Philadelphia – 2015

WD77 77-Room 300, CC Supply Chain Competition II Contributed Session Chair: Masoud Narenji, Doctor, Iran University of Science and Technology, Narmak, Tehran, 1894119493, Iran, mnarenji@iust.ac.ir alexander.rothkopf@uni-wuerzburg.de, Eirini Spiliotopoulou Recently global health buyers granted volume guarantees to pharma manufacturers in an effort to reduce prices through competition and higher economies of scale. However, guaranteeing volumes affect market competition and new supplier entry in the future. Our analysis lends insights to policy makers how to optimally structure a volume guarantee. 2 - Information Asymmetry and Competitive Implications for Horizontal Outsourcing Seung Hwan Jung, Washington University in St. Louis, Olin Business School, Campus Box 1133, 1 Brookings Drive, We investigate the role of information asymmetry in business relationship between competing firms. We consider a two-echelon supply chain in which a vertically integrated (VI) firm sells a component to a component outsourcing (CO) firm. The VI firm has its own brand which competes with the CO firm’s product. Under this circumstance, we characterize firms’ sourcing and pricing decisions. This work highlights the role of information asymmetry in competing firms’ operational strategy. 3 - Impact of Channel Power and Fairness Concern on Supplier’s Market Entry Decision Jie Zhang, Associate Professor, Guangdong University of Finance and Economics, 21 Luntou Road, Haizhu District, Guangzhou, 510320, China, jiezh@gdufe.edu.cn, Baozhuang Niu We consider a two-stage supply chain with a supplier and a retailer, and incorporate the concepts of channel power and fairness concern to analyze the supplier’s decision on its online direct channel. We show that a direct channel leads to the decline of online product’s quality and its price. Furthermore, the retailer’s order shifting strategy results in a lose-lose situation for the two firms. We also find that the supplier’s fairness concern may make it less likely to open an online channel. 4 - Integrated Bioenergy Supply Chain Optimization under Crop Competition and Uncertainties Yuanzhe Li, PhD Student, University of California, Davis, Dept. of Civil & Environmental Engineer, Ghausi Hall, One Shields Avenue, Davis, CA, 95616, United States of America, rgli@ucdavis.edu, Yueyue Fan An integrated optimization program was developed to model the bioenergy production system where dedicated energy crop is competing with incumbent agricultural crops as feedstock. The model addresses crop adoption decisions under competition and infrastructure deployment strategies under supply and demand uncertainties simultaneously. A case study for the U.S. Pacific Northwest region is conducted to obtain practical insights for the industry. 5 - Competition of Supply Chains and Their Internal Elements in a Market with Two Classes of Customers Masoud Narenji, Doctor, Iran University of Science and Technology, Narmak, Tehran, 1894119493, Iran, mnarenji@iust.ac.ir, Mohammad Fathia We follow competition and coordination strategies between two chains. Each supply chain has a manufacturer and a distributor. There are two types of customers with different sensitivity to price and delivery time. Each member of a chain can choose their own individual policy (dedicated or shared capacity) with respect to importance of the customers. The evolutionary game approach was followed to illustrate the best combination of strategy-policy, and heuristic methods was used to solve them. 1 - Volume Guarantees in Global Health Procurement Alexander Rothkopf, Julius-Maximilians-University Wuerzburg, Stephanstrafle 1, Wuerzburg, Germany, St. Louis, MO, 63130, United States of America, seunghwan.jung@wustl.edu, Panos Kouvelis

WD78 78-Room 301, CC Analytic Hierarchy Process Contributed Session

Chair: Luis Vargas, Professor, Business Analytics and Operations, Joseph M. Katz Graduate School of Business, University of Pittsburgh, 356 Mervis Hall, Pittsburgh, PA, 15260, United States of America, lgvargas@pitt.edu 1 - Impact of NPD-SCM Alignment on Competitiveness of Indian Automotive Industry Bimal Nepal, Associate Professor, Texas A&M University, 3367 TAMU, College Station, TX, 77843, United States of America, nepal@tamu.edu, Ankur Pareek, Ajay P.S. Rathore, Rakesh Jain This paper attempts to measure NPD-SCM Alignment and evaluate its impact on Competitive Advantage in comparison to some established competitive priorities such as Cost, Quality, Delivery, Flexibility, and Innovation. A large scale survey data from Indian automobile industry has been collected and analyzed using ANP to capture the effect of inter-dependence among variables. Findings have been validated through three longitudinal in-depth case studies. 2 - From Actors’ Analysis to Multicriteria Decision Aiding: A Mixed Method Approach Valentina Ferretti, Politecnico of Torino, Corso Castelfidardo 30/A, Torino, Italy, valentina.ferretti@polito.it This paper proposes a methodological approach based on the combined use of different tools for designing complex urban regeneration processes. The purpose of the paper is to investigate synergies between the Social Network Analysis of actors and stakeholders and the Analytic Network Process in order to support the design of urban regeneration strategies. The framework has been tested on a real case study concerning the requalification for abandoned military barracks in Turin (Italy). 3 - Voting with Intensity of Preferences Luis Vargas, Professor, Business Analytics and Operations, Joseph M. Katz Graduate School of Business, University of Pittsburgh, 356 Mervis Hall, Pittsburgh, PA, 15260, United States of America, lgvargas@pitt.edu In this paper we develop a method based on the idea of pairwise voting to rank projects or candidates and incorporate in the ranking process how strongly the referees/voters feel about the comparisons they make. Voting is a modified form of ranking and all the votes are equally important. However, there are situations similar to voting in which the votes are not just ordinal but each voter expresses an intensity of preference for the different candidates, e.g., ranking projects for funding. WE01 01-Room 301, Marriott Scheduling, Workload and Complexity Sponsor: Military Applications Sponsored Session Chair: Thomas Willemain, TomW@smartcorp.com 1 - A Simulation Optimization Approach for a Task Process to Balance Mental Workload Cansu Kandemir, Old Dominion University, 5115 Hampton Blvd., Norfolk, VA, 23529, United States of America, ckand002@odu.edu, Holly A. H. Handley This research employs a human performance modeling simulation tool with meta-heuristic methods in order to assign personnel to tasks based on credentials, while still maintaining a workload balance among them. An initial simulation- optimization application on the task process of “Air Interdiction Mission Planning” will be presented. Wednesday, 4:30pm - 6:00pm
