2 - Measuring Interculture Competence Among Business, Education
and Social Work Students

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

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.

1 - Versioning, Trade-ins and Refurbishing: An Integrative Analysis

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

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,
, 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.

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.

1 - An Airspace Sectorization Approach Based on Spectral
Clustering and NSGA-II
Bang An, Tsinghua University, Room 616, Main Building, Beijing,
China, 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,

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

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,
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.
