2 - Measuring Interculture Competence Among Business, Education and Social Work Students Amarpreet Kohli, Assistant Professor, Farmingdale State College, SUNY, Farmingdale, NY, United States of America, kohlias@farmingdale.edu, Hermeet Kohli, Cheng Peng Purpose of this interdisciplinary research was to measure the level of multicultural awareness, sensitivity to, and understanding of difference, and intercultural competence when working in diverse environments in the undergraduate and graduate Business, Education and Human Development, and Social Work students using the UDO (MGUD-S Survey). Convenient purposive sampling was utilized to invite students enrolled in these three schools to participate in web based descriptive survey research. 3 - Redesigning Qatar University Class Meeting Pattern to Improve Performance Omar Ben-ayed, Professor Of Management, Qatar University, This study examines the existing class meeting pattern at Qatar University based on the strategic plan of the University in addition to the perception of students and faculty members. The study shows that there is a need for a new class meeting pater with two additional non-teaching half-days. A capacity analysis proves the feasibility of such a pattern. Accordingly, alternative class meeting patterns are proposed and one is selected based on technical, academic and cultural perspectives. TB61 61-Room 111B, CC Economics of Reverse Logistics and Sustainable Operations Sponsor: ENRE – Environment I – Environment and Sustainability Sponsored Session Chair: Shouqiang Wang, Assistant Professor, Clemson University, 131D Sirrine Hall, Clemson, SC, 29672, United States of America, shouqiw@clemson.edu 1 - Versioning, Trade-ins and Refurbishing: An Integrative Analysis Avinash Geda, University of Florida, 361B Stuzin Hall, Gainesville, FL, 32611, United States of America, avinashgeda@ufl.edu, Tharanga Rajapakshe, Asoo Vakharia We consider a monopolist durable goods manufacturer who markets its products via a single retailer. In the first period, the manufacturer introduces first version of the product while he may introduce the second and refurbished versions of the product in the second period. We consider there exists a secondary market where consumers can resell the old products. We investigate the impact of introduction of a trade-in and refurbishing program on the product versioning decision of the manufacturer. 2 - Trade-Ins Versus Upgrades: A Behavioral Exploration Mahdi Mahmoudzadeh, Georgia Institute of Technology, 800 W Peachtree ST NW, Atlanta, GA, United States of America, Mahdi.Mahmoudzadeh@scheller.gatech.edu, Beril Toktay, Basak Kalkanci Understanding customers’ behavior in selling positions or exchanging their products would help better manage replacement purchases and product return streams. We study trade-ins and upgrades, which so far have been assumed to be equivalent. We find that customers perceive trade-ins and upgrades differently; perceived importance of the quoted price for current product is more salient in trade-ins than in upgrades. Our results are useful to find dominant replacement offers and pricing strategies. 3 - Design and Technology Choice for Recycling: The Value of Collaboration and Capacity Ownership Luyi Gui, Assistant Professor, UC Irvine, United States of America, luyig@exchange.uci.edu, Morvarid Rahmani, Atalay Atasu Efficient and effective treatment of end-of-life products requires not only product design improvements but also advancement in recycling technologies. We analyze how Extended Producer Responsibility (EPR) legislation would affect incentives for improving product recyclability and processing technology. In particular, we take into account the mutually reinforcing effect between product and process improvements and explore the implication of such complementarity in EPR implementation.

4 - Inducing Environmental Disclosures: A Dynamic Mechanism Design Approach Shouqiang Wang, Assistant Professor, Clemson University, 131D Sirrine Hall, Clemson, SC, 29672, United States of America, shouqiw@clemson.edu, Peng Sun, Francis De Véricourt This paper studies the design of voluntary disclosure regulations that jointly uses inspections and monetary rewards. We formulate this problem in a dynamic mechanism design framework with state verification and obtain complete analytical solution. TB62 62-Room 112A, CC Aviation Applications Contributed Session Chair: Jinkun Lee, The Pennsylvania State University, 236 Leonhard, University Park, United States of America, jinkunlee@psu.edu 1 - An Airspace Sectorization Approach Based on Spectral Clustering and NSGA-II Bang An, Tsinghua University, Room 616, Main Building, Beijing, China, ab13@mails.tsinghua.edu.cn, Peng Cheng, Xiang Zou We propose an airspace sectorization approach based on spectral clustering and NSGA-II. With the method embedded in the constrained NSGA-II, all of the critical constraints can be easily handled. Besides, an initial sectorization method based on spectral clustering is proposed to generate the first generation of NSGA- II. We test our method on the high-altitude airspace controlled by Beijing Area Control Center. The results show that our method can obtain better solutions. 2 - A Preemptive Scheduling Model with Overtime Allocation for Minimum Weighted Tardiness Fernando Jaramillo, University of Miami, 1251 Memorial Drive, Department of Industrial Engineering, Coral Gables, FL, 33146, United States of America, f.jaramillo2@umiami.edu, Busra Keles, Murat Erkoc We develop a model and solution procedure for preemptive scheduling with overtime option. The problem is mainly motivated by the aviation MRO industry where late deliveries of overhaul orders are costly. Our model aims at minimizing the total cost of overtime and tardiness over a finite number of jobs with different weights, release dates and due dates. A multi-pass heuristic algorithm is proposed to solve the scheduling and capacity allocation problem. 3 - Optimal Learning Control of Drone Operation Jinkun Lee, The Pennsylvania State University, 236 Leonhard, University Park, PA, United States of America, jinkunlee@psu.edu, Vittal Prabhu An optimal learning control of individual delivery drone has been considered. This enables each drone to adapt its path for the minimum travel time according to its own repetitive experience of the dynamic environment. The estimated travel times of drones are fed back into the central server, and this server determines the proper number of drones to fulfill the delivery service level based on the accumulated real time demands during the previous drone operation time window. 4 - Integrating Taxi Planning and Gate Assignment Angel Marin, Professor, Polytechnical University of Madrid, ETSI Aeronautica y Del Espacio, Plaza Cardenal Cisneros, 3, Madrid, MA, 28040, Spain, angel.marin@upm.es In the presentation is studied the Taxi Planning and Gate Assignment Integration. These problems are considered under a binary multicommodity network flow, in the context of routing and scheduling models with additional Side Constraints (SC). The model is a multiobjective approach balancing conflictive objectives: airport throughput, travel time, delays, operation safety and costs, etc. The computational tests are realized on test airports, simulating actual ones.
