3 - Reliability and Economic Analysis of IP Cameras with Shielding Devices Rodolfo Lozano, Texas A&M.University-Kingsville, Kingsville, TX, United States, rudylozanoiv@gmail.com, Hua Li, Kai Jin, Yue Zhang The utilization of sophisticated outdoor IP surveillance cameras has led to significant increases in waste electrical and electronic equipment (WEEE) due to the degradation associated with direct insolation, thermal cycling and inclement exposure. This study seeks to apply a patent pending shielding device to IP cameras in a school district to attain the difference of operating temperatures between shielded and unshielded IP cameras. The failure rates of the hardware elements related to temperature are derived to conduct a reliability study. The results from reliability studies are used to investigate the economic benefits associated with installing the shielding devices. 4 - Multi-objective Optimization Model for Designing Reliable Networks Seyedmohsen Hosseini, University of Southern Mississippi, 730 East Beach Boulevard, Long Beach, MS, 39560, United States, mohsen.hosseini@usm.edu Network design problem (NDP) is a well-known combinatorial NP-hard which involves selecting a subset of network edges with respect to different objectives such as maximizing the network reliability and/or minimizing the network cost. This work presents a multi-objective optimization model to solve NDP. An adapted Non-dominated sorting genetic algorithm is proposed to deal with complexity of NDP. An illustrative example is worked out to illustrate the performance of proposed algorithm. 5 - ALT with Hyperbolically Changing Stress Durations under Cost Constraint David Han, University of Texas at San Antonio, Management Science & Statistics, College of Business, San Antonio, TX, 78249-0632, United States, david.han@utsa.edu When designing ALT, several variables such as the allocation proportions and stress durations must be determined carefully because of constrained resources. This talk discusses the optimal decision variables based on the popular optimality criteria under the constraint that the total cost does not exceed a pre-specified budget. A general scale family of distributions is considered to accommodate different lifetime models for flexible modeling with hyperbolically decreasing stress durations. 6 - Joint Optimal Pricing and Two Dimensional Warranty Policy for New Products in a Dynamic Market Jinfu Zhang, Tsinghua University, RM.413 BLDG 14#, Warranty can be used to promote sales of a product, but may incur high servicing cost. An optimal warranty policy that can well balance the two is thus desired. Considering that customers usually use the same type of products under different usage rates, we seek to design a two-dimensional warranty policy that takes both the covering time length and customer usage into account. The revenue earned by selling a product is also influenced by its price. Thus, we propose a model to jointly optimize a product’s price, warranty length and usage for maximizing the total profit in a dynamic market.

2 - Tax or Subsidy? An Analysis of Environmental Policies in Supply Chains Xuan Zhao, Associate Professor, Wilfrid Laurier University, 877 Creekside Dr., Waterloo, ON, N2V. 2S7, Canada, xzhao@wlu.ca, Junsong Bian This paper investigates the impacts of two environmental policies: pollution abatement subsidy and pollution emission tax, to a government-manufacturer- retailers supply chain, where the manufacturer invests in a pollution abatement technology. 3 - Characterizing the Association Between U.S. Domestic Water Consumption Patterns over 2005-2010 and Socioeconomic Factors David Yang, Winston Churchill High School, 13430 Bissel Lane, Potomac, MD, 20854, United States, david121yang@yahoo.com, Roshanak Nateghi Water consumption sustainability is a major national and global issue. Analyzing the United States Geological Survey (USGS) data shows that after a long period of steady increase in domestic water use, there was a decrease from 2005 to 2010, despite increased population. In this research, we focused on domestic water use per capita in 2005 and 2010 and found California, Nebraska, Nevada and Texas had the largest decrease. We leveraged statistical learning methods to identify socioeconomic factors that may influence domestic water use. Our analysis indicated that land area, household size and age of houses built are key factors in characterizing change of domestic water consumption. 360E Project Management Contributed Session Chair: Yongcheng Fu, The University of Manchester, Manchester, United Kingdom, yongcheng.fu@postgrad.mbs.ac.uk 1 - Parents’ Management Control Over International Joint Ventures for Overseas Infrastructure Investment Leijie Han, Tianjin University, 92 Weijin Road, Tianjin, China 300072, Tianjin, 300072, China, sherry_hlj@163.com, Shuibo Zhang We examine how goal incongruence between international joint venture (IJV) parents and task interdependence between parents and IJVs affect parents’ investment in management control mechanisms: behavior, output and clan. We then explore the balance of control investment and residual risk under environmental uncertainty. The results from an empirical research show positive relationships between all these control mechanisms and goal incongruence, while only behavior and clan control are positively related to task interdependence. Besides, environmental uncertainty weakens the relationships related to behavior and output control, but enhances the relationships related to clan control. 2 - The Importance of Project Management to Drive Competitive Advantage in Data Analytics and Research Organizations Mou Dutta, Strategic Analytics Leader, Genpact, 29 Hoyt Street, Stamford, CT, 06905, United States, drimjhim36@gmail.com Data analytics is transforming the business end to end with smart intelligent insights challenging the conventional thought process and enabling the leaders to optimize their business strategy. While analytical methodologies have been widely used in traditional project management arena of agile software industry, the growing importance of managing the scope creep and implementation uncertainty calls for a robust project management framework for successful deployment of analytics engagements. This paper discusses the challenges in analytics operations posed by complex business environments and how effective project management can drive competitive advantage and strategic value chain. 3 - Early Termination Compensation under Demand Uncertainty in Public-private Partnership Projects Jinbo Song, Professor, Dalian University of Technology, Dalian, 116024, China, songjinbo@dlut.edu.cn, Yanzhu Yu, Lulu Jin, Zhuo Feng In the early termination of public-private partnership (PPP) projects, compensation is considered a core issue that greatly affects the interests of both the government and private sector. To address the early termination that is frequently caused by government default or voluntary buyback, this paper proposes an ex-ante compensation mechanism by using the cumulative probability that a given demand could be realized to determine the early termination compensation under demand uncertainty. The proposed compensation mechanism hopefully avoids time-consuming negotiations and high ex-post costs and provides a win-win outcome for both parties to manage the early termination of PPP projects.

360D Sustainability Contributed Session

1 - Impacts of Consumer Awareness, Government Penalty and Retailer’s Responsibility on Upstream Pollution in a Supply Chain Jeong Eun Sim, Korea Advanced Institute of Science and Technology, KAIST Business School, 85 Hoegiro Dongdaemoon, Seoul, Korea, Republic of, jesim@kaist.ac.kr, Bowon Kim We study the impact of diverse stakeholders that may influence manufacturer’s polluting emission in a supply chain. Specifically, we examine which one between the two key forces, i.e., consumers’ environmental awareness and government penalty, is more effective in reducing pollution and whether they are substitutes or complements. Furthermore, we investigate the effect of retailer’s environmental responsibility on the upstream pollution. To this end, four differential game models are developed depending on consumer awareness and supply chain strategy.
