报告题目: Heavy-Traffic Analysis of Large-Scale Service Systems with Dependent Service Times
报 告 人: Dr. Guodong Pang,Penn State University
时间地点: 2012年7月16日下午2:00 S1013
摘       要: In service systems there can be dependence among successive service times. For example, in a telephone call center responding to service calls, a product defect can lead to many calls concerning that same product over a period of time, which may require similar handling times. For another example, in a hospital emergency room, there may be multiple patients associated with the same medical incident, and their treatment can be highly correlated. Thus it is interesting to understand the impact of dependence among the successive service times upon the ability of a service system to respond to service requests. We consider the many-server queueing models with general arrival processes possibly having time-varying arrival rates and multiple parallel statistically identical servers. Instead of assuming i.i.d. service time distributions as in standard analysis, we allow the successive service times to be dependent, specifically, we assume that the successive service times form a sequence of weakly dependent random variables satisfying certain mixing conditions. We establish heavy-traffic fluid limit and its refined stochastic limit for the associated offered load processes, that is, the number of customers in the corresponding system with infinite number of servers. We provide an accurate approximation of the delay probability and a refined square root staffing rule. (This is joint work with Dr. Ward Whitt, Columbia University.)

报告题目: Mathematical Modeling of Performance Evaluation for a Synchronized Zone Order Picking System
报 告 人: Sydney C.K. Chu (朱进强) & Pan Li (潘莉),The University of Hong Kong
时间地点: 2012年6月25日下午4:00 S1013
摘       要:

Order picking is the process of retrieving items from storage areas to meet customer's requirement, and is the most labor-intensive operation in warehouse. In order to operate efficiently, the order picking process needs to be delicately designed and optimally controlled. In this talk, performance of a low-level picker-to-part order picking system with synchronized zone is studied. First, an analytical model studying the performance of three routing and storage strategy combinations are introduced, followed by a simulation model to further study the impact of various design parameters and operational policies. The results obtained from the analytical models are compared and validated in simulation experiments; and they appear to provide acceptable approximation results. The simulation model in the second section has shown that the routing, storage policies, demand patterns, order, batch and zone sizes have tremendous effect on the efficiency.

报告题目: Plant-based bioproduction of pharmaceutical proteins – using cross-disciplinary approaches from informatics to immunology to drive innovation
报 告 人: Carole L. Cramer, PhD.,Professor, Arkansas Biosciences Institute, Arkansas State University, and Co-founder, BioStrategies LC, State University
时间地点: 2012年6月15日上午10:30 S1013
摘       要:

Plants have emerged as effective systems for the bioproduction of complex high-value proteins for medical applications. When compared to human proteins produced in cultured animal cells, these plant-based systems provide advantages in safety, scalability and cost, especially up-front capitalization to establish production capacity. The first generation plant-made pharmaceutical proteins are now commercialized and providing life-saving medicines to patients. Further innovations are under development that accelerate the bioproduction timeline in plants and enhance therapeutic protein delivery and stability. Several case studies involving the development complex plant-made therapeutic proteins will be presented that highlight the importance of integrating multi-disciplinary approaches and expertise encompassing plant biology, biochemical engineering, cell biology, immunology, bioinformatics, and medical/veterinary sciences in order to effectively move these products forward. The increasing relevance and effectiveness of computational approaches including protein structure prediction and transcriptome analyses will be discussed in the context of specific biological problem solving, targeting both basic mechanistic discovery and practical application goals.

报告人简历:

Dr. Cramer is an internationally recognized pioneer and leader in the area of plant-made pharmaceutical proteins. Her discovery that plants could effectively produce fully active human lysosomal proteins led to the first systemically administered plant-made therapeutic to attain US FDA approval in May 2012. This protein is an enzyme replacement therapeutic for Gaucher Disease, a rare lysosomal storage disease, that is manufactured in cultured carrot cells by Protalix Biotherapeutics and marketed worldwide by Pfizer. Dr. Cramer currently serves as the Director of the Arkansas Center for Plant Powered Production (P3 Center; www.plantpoweredproduction.org), a multi-institutional research consortium funded by the US National Science Foundation and the Arkansas Science and Technology Authority. This Center, comprising more than 50 faculty at 5 universities, fosters research and discovery through cross-disciplinary collaboration and infrastructure development and support. Dr. Cramer previously served as the founding executive director for the Arkansas Biosciences institute at Arkansas State University leading the development of 90,000 sq.ft. research facility focused on innovative research at the interface of medicine, agriculture, and the environment. She also served on the US Department of Agriculture Advisory Committee for 21st Century Agriculture and the Biotechnology Industry Organization (BIO) subcommittee on plant-made pharmaceuticals. Dr. Cramer is also an entrepreneur having cofounded several biotechnology start-up companies. Her current company,BioStrategies-LC , was recently recognized with the prestigious 2012 Tibbetts Award for excellence in innovation presented at the White House in Washington DC.

报告题目: Wealth vs Risk in a Continuous Time Model
报 告 人: Prof Harry Zheng,Imperial College, UK
时间地点: 2012年4月6日上午10:00 S703
摘       要:

In this talk we discuss a continuous time optimization problem which combines two conflicting objectives of maximizing
the portfolio wealth up to a level and minimizing the conditional value-at-risk of the portfolio wealth loss. The standard utility maximization theory cannot be applied to solve the problem as the associated utility function is not differentiable nor strictly concave and does not satisfy Inada's condition. We use the dual control method to show that there is a classical solution to the Hamilton-Jacobi-Bellman equation and that the optimal value function is smooth if the optimal control satisfies an exponential moment condition. We find the closed-form optimal feedback control and optimal value function for a wealth maximization problem.

报告题目: A non-commutative analog of gradient flow in the 2-Wasserstein metric
报 告 人: Eric Carlen, Professor, Rutgers University, USA
时间地点: 2012年3月16日下午4:00 S703
摘       要:

I present an analog of the 2-Wasserstein metric in a non-commuatative probability setting arising in quantum mechanics that has been developed by Jan Maas and myself. It will be shown that the Femionic Ornstein-Uhlenbeck equation is the gradient flow for the relative entropy with respect to the equilibrium state, and analogy with a well known result of Otto, Kinderleher and jordan, and we prove a sharp non-commutative Talagrand inequality as well. We shall also discuss a range of open problems.

报告题目: Recent Progress on Kac's Probabilistic Approach to Kinetic Theory
报 告 人: Profssor Maria Carvalho, University of Lisbon, Portugal
时间地点: 2012年3月15日下午3:00 S703
摘       要:

Kinetic theory describes the evolution of dilute gas of particles interacting through binary collisions. The equations of kinetic theory are non-linear evolution equations (various forms of the Boltzmann equation for a probability density. In 1956, Mark Kac proposed a strategy for investigating such equations via a direct analysis of a stochastic model, different from, and simpler than, the underlying physical collision model, but still leading to the same equations.
There has been much recent progress on Kac's program. We shall discuss recent work on determining the rate of equilibriation
in this model. Until now, this had only had been made only Maxwellian molecules, or, in a singular result of Villani, for super-hard collisions Recent work of myself, Carlen and Loss extends this progress to the physically significant hard-sphere case, as will be explained in this lecture. I will also discuss recent results of Mischler and Mouhot on propagation of chaos for this model that makes use of the new rate information.
