4 - Firm’s Green Supply Chain Performance: Effects of Outsourcing to Emerging Markets Pritha Dutta, Doctoral Student, University of Massachusetts,Amherst, Isenberg School of Management,, UMass, Amherst, MA, 01003, United States of America, pdutta@umass.edu, Adams Steven “Outsourcing” and “sustainability” are the two most significant buzz words in the realm of supply chain management today.The past decade has seen a growing trend of outsourcing and off-shoring of operations by companies. This is also an age where firms are becoming more and more aware of their corporate social responsibilities and environmental impacts. Hence in this paper we intend to study the effect of a company’s outsourcing/off-shoring policies on the overall green performance.

Software Demonstration Cluster: Software Demonstrations Invited Session 1 - SAS JMP Division – Interactive and Visual Data Analysis with JMP 12 Pro David Revenew, JMP Academic Ambassador, SAS JMP Division JMP Statistical Discovery Software is interactive and visual desktop software for Windows and Mac, with a complete array of integrated graphical and statistical procedures. We will demonstrate JMP tools for data analysis, visualization and exploration, including, Graph BuilderÆ, bubble plots, the data filter, and our popular mapping tools. In addition to interactive techniques for Univariate and Bivariate analysis we will look at methods for Multivariate analysis including Clustering, Principal Components and Data Mining. 2 - AnyLogic – anyLogistix – Every Supply Chain is Unique, Capture Yours!

Chair: Sungyong Choi, Assistant Professor, Yonsei University, 1 Yonseidae-gil, Wonju, Korea, Republic of, sungyongchoi@gmail.com 1 - Do Credit Agencies Predict the Financial Strength of a Supply Chain? Gurkan Akalin, Eastern Illinois University, 905 A Street, Apt. 4, Charleston, IL, 61920, United States of America, gurkanakalin@hotmail.com This study shows the results from our research about the effectiveness of Credit Agencies in predicting the strength of a company’s supply chain. 2 - Inventory Control Policy in a Decentralized Assembly System: The Role of Vendor Inventory Liability Guo Li, Dr., Beijing Institute of Technology, No. 5 Zhongguancun South Street, Beijing, 100081, China, lg4229682@163.com, Xu Guan We investigate a decentralized assembly system that consists of one dominant manufacturer and multiple suppliers who produce the complementary components. The manufacturer initially sets a VILP to control the suppliers’delivery times, and multiple suppliers simultaneously determine when to deliver their components.We yield many interesting results based on their decision. 3 - Ripple-Effect and Structure Dynamics in the Supply Chain Dmitry Ivanov, Professor Dr., Berlin School of Economics and Law, Badensche Str. 50, Berlin, 10825, Germany, divanov@hwr-berlin.de This study aims at presenting the ripple effect in the supply chains in terms of structure dynamics framework. The supply chain structure dynamics framework is presented. We show an example of considering the ripple effect and structure dynamics in a supply chain design and planning obtained in a practical project for a multi-stage production-distribution network. Finally we identify gaps in current research and delineate future research avenues. 4 - Product Recalls, Category Effects and Competitor Response Ram Bala, Santa Clara University, 500 El Camino Real, Santa Clara, CA, 95050, United States of America, rbala@scu.edu, Pradeep Bhardwaj, Pradeep Chintagunta Product recalls are ubiquitous in a variety of industries. We focus on product categories where an individual firm’s product recall may have negative consequences for the entire category. In such contexts, competitors in the category would have to respond to the recall through their sales effort. We provide a prescriptive road map for firms facing this decision based on several factors such as the anticipated category level loss and economies of scope in sales resource use across categories.

Chair: Michael Hirsch, ISEA TEK, 620 N. Wymore Rd., Ste. 260, Maitland, FL, 32751, United States of America, mhirsch@iseatek.com 1 - Sea Escort Transportation Azar Sadeghnejad Barkousa, SUNY at Buffalo, 4545 Chestnut Ridge Rd, Apt. 221A, Amherst, NY, 14228, United States of America, azarsade@buffalo.edu, Rajan Batta, Moises Sudit Increasing number of violent pirate attacks causes a significant threat to the global shipping industry, with annual costs estimated at up to US$12 billion. On the other hand, countries facing piracy are usually poor countries whose governments are unable to invest as much money as needed to protect the area. In this study we model the assignment and scheduling of escort ships along with commercial ships in danger zones to maximize protection with limited number of escort vessels. 2 - Anthropometric Casualty Estimation Methodologies for Modeling and Simulation Daniel Rice, Technology Solutions Experts, Inc., 209 W. Central Street, Natick, MA, United States of America, daniel.rice@tseboston.com, Medhat Korna, Daniel Louzeiro, Ashley Drag The design of Personal Protective Equipment (PPE) is critical to soldier survivability for a range of combat operations. Digital human modeling, simulation, and analysis play a critical role in supporting this technology priority. This research provides new capabilities for analysis of PPE fit and form for a range of body shapes and sizes through the use of high-resolution digital 3D models for improved analysis capabilities to support scientists engaged in the design of future PPE systems. 3 - Combining Simulation and Optimization to Increase Insights Walt Degrange, Principal Operations Research Analyst, CANA Advisors, 6727 Falconbridge Rd., Chapel Hill, NC, 27517, United States of America, wdegrange@canallc.com, Benjamin Thengvall This research uses a simulation modeling USMC Maritime Prepositioning Force (MPF) exercises in ExtendSim and an optimization tool (OptDef) to increase the insight gained over using a simulation or optimization individually. We start by demonstrating the methodology with a small scale model and then increase the size of the model to test the robustness of the technique. We also cover the pros and cons of using this combination and lessons learned through integrating these tools.

5 - A Parametric Study of Risk-Averse Inventory Models Sungyong Choi, Assistant Professor, Yonsei University, 1 Yonseidae-Gil, Wonju, Korea, Republic of, sungyongchoi@gmail.com

I study a few dynamic risk-averse inventory models using additive utility functions. I add Markovian behavior of purchasing costs in my models. Such Markovian purchasing costs can reflect a market situation in a global supply chain such as random fluctuations at exchange rates or the existence of product spot markets. I provide my parametric analytical results with finite and infinite MDP (Markovian Decision Process) problems.
