航运公司合作下的海运空箱调运模糊优化模型

目的对单独调箱与合作调箱策略进行对比分析,以期为航运公司选择最佳调箱策略提供参考。方法考虑港口空箱供需差和运力约束的模糊性,以空箱调运总成本最小为目标,建立基于航运公司合作的海运空箱调运模糊优化模型,并通过LINGO建模求解具体算例。结果与单独调箱策略相比,采用合作调运策略能够有效降低航运公司的物流总成本。其中0.32%来自存储成本的节约,54.05%来自租箱成本的节约,45.63%来自运输成本的节约。结论采用合作调箱策略,能够降低航运公司空箱调运的总成本,能够弱化单位空箱存储成本和租赁成本的增加对空箱调运总成本的影响,但单位运输成本和运费加成因子的增加会降低合作调运空箱策略的优势。

High-Performance Telemedicine Information Management

The rapid advances in high performance global communication have accelerated cooperative image-based medical services to a new frontier. Traditional image-based medical services such as radiology and diagnostic consultation can now fully utilize multimedia technologies to provide novel services, including remote cooperative medical triage, distributed virtual simulation of operations, as well as cross-country collaborative medical research and training. Fast (efficient) and easy (flexible) retrieval of relevant images remains a critical requirement for the provision of remote medical services. This paper describes the database system requirements and presents a system architecture of a distributed multimedia database system, MISSION-DBS, which has been designed to fulfill the goals of Project MISSION (medical imaging support via satellite integrated optical network)—an experimental high performance gigabit satellite communication network linking remote supercomputing power, medical image databases, and 3D visualization capabilities, in addition to medical expertise anywhere and anytime around the globe. The MISSION-DBS design employs a synergistic fusion of techniques in distributed databases (DDB) and artificial intelligence (AI) for storing, migrating, accessing, and exploring images. The efficient storage and retrieval of voluminous image information is achieved by integrating DDB modeling and AI techniques for image processing while the flexible retrieval mechanisms are accomplished by combining attribute-based and content-based retrievals.     

Production Games under Uncertainty

The main objects below are transferable-utility games in which each agent faces an optimization problem, briefly called production planning, constrained by his resource endowment. Coalitions can pool members' resources. Such production games are here extended to accommodate uncertainty about events not known ex ante. Planning then takes the form of two-stage stochastic programming. Core solutions are sought, described, and computed via aggregate dual programs. The analysis is motivated by practical applications. Examples include stochastic production and regional distribution with random demand and supply, illustrated by a numerical example.
