Selecting optimum communication technology for a distributed workgroup such as an electric supply cooperative with a number of sub-stations is a challenge. A quantitative approach to evaluate the various communication technologies based on multicriteria is needed to select optimum communication technology. An electric cooperative in Minnesota was used for a case study and the various communication technologies used (frame relay, fiber optic etc) were investigated. Analytical Hierarchy Process for multicriterion was used to select optimum communication technologies between the sub-stations. The analysis showed that for sub-stations within 10 miles of the hub fiber optic was the most preferred form of communication technology. For distances over 10 miles satellite system was the preferred communication technology. Selection of appropriate communication technology improves the efficiency of the distributed workgroup. Substantial savings in communication costs can be achieved by optimizing the communication technology system.

We consider N-stage serial production/distribution systems with stationary demand at the most downstream stage. First, we study classical Clark-Scarf model with both average cost and discounted cost criteria. The optimal echelon base-stock levels are obtained in terms of only probabilistic distributions of leadtime demand. This analysis yields a novel approach for developing bounds and simple heuristics for optimal echelon base-stock polices. In addition to deriving known bounds, we develop several new upper bounds for both average cost and discounted cost models. Second and more important, we extend this idea to a more general model with two transportation modes between stages: the regular and expedited shippings (Lawson and Porteus (2000)). The optimal inventory policy for this system is known to be echelon base-stock policy, which can be computed through minimizing 2N nested convex functions recursively. We again develop simple newsvendor type of lower and upper bounds for the optimal control parameters, as well as a simple near optimal heuristic. Extensive numerical results show that the heuristics for both models perform well. The bounds and heuristic enhance the accessibility and implementability of the optimal policies in supply chains with single and dual transportation modes.

Canadian Conference on Electrical and Computer engineering (CCECE)

作者： Anas N. AbuLaban Ghassan Z. Qadah Engineering Systems Management Program American University of Sharjah Sharjah UAE Computer Engineering Department American University of Sharjah Sharjah UAE

An online auction is simply defined as a virtual marketplace hosted on the Internet to match buyers and sellers of goods around the globe regardless of the physical limitations of traditional auctions such as geography, presence, time, and space. Online auctions operate different protocols including English, Dutch, First-Price Sealed Bid and Vickrey with different properties for each one of these protocols. This paper reviews the different types of auctions and the strategies proposed in support of buyers and sellers participating in these auctions. Seller strategies for auctions that adopt protocols other than English are then presented. A scheme that integrates a number of strategies suitable for one of the auction types, namely the Dutch auction, is then developed and discussed

2005 BRAC Attribute Analysis

2005 BRAC Attribute Analysis

IEEE Symposium on systems and Information engineering Design, SIEDS

作者： Matthew Lee Jack Noblin Brian Reynolds Brad Roberts Timothy Trainor Department of Systems Engineering United States Military Academy West Point NY USA Director of the Engineering Management program United States Military Academy West Point NY USA

In 2005, the Department of Defense completed its fifth round of base realignment and closure (BRAC). This process involved analytically determining the military value (MV) of an installation and then ranking all installations based on MV scores. These rankings were used to determine which installations would be closed or realigned, subject to meeting minimum Army requirements for maintaining certain functions. In 2005, the MV score for an installation was derived as a weighted sum of the installation's score over a set of forty attributes. This paper describes the methods we used in analyzing these attributes, our goal being to identify the attributes that had the greatest impact on the installation rankings. From our analysis, we developed recommendations on which attributes should be kept for future BRAC proceedings, as well as those that could be considered for revision

This subject, Urban Wet-Weather Flows, is comprised of three basic subareas - combined-sewer overflows (CSOs), sanitary-sewer overflows (SSOs), and stormwater discharges. Major proceedings related to wet-weather flow (WWF) published during 2005 were the following: (1) WEFTEC 2005, 78th Annual Conference and Exposition (WEF, 2005);(2) Effective Modeling of Urban Stormwater systems, Monograph 13 (CHI, 2005);and (3) 2005 Watershed management Conference - Managing Watersheds for Human and Natural Impacts (EWRI, 2005). In addition to the conferences listed above, the 2005 Annual Conference of the American Water Resources Association, EWRI's World Environment and Water Resources Congress the 10thInternational Conference on Urban Drainage had significant sessions on wet-weather flows. In addition, many regional conferences also had significant sessions on wet-weather flow issues, such as the 2005 Pennsylvania Stormwater management Symposium. For all of these, no indexed paper proceedings had been indexed at the time that this literature review was prepared. Copyright © 2006 Water Environment Federation.

New approach to transportation planning for the 21st century: Regional strategic transportation planning as a complex large-scale integrated open system

引用

Transportation Research Record 2005年第1931期1931卷 89-98页

作者： Sussman, Joseph M. Sgouridis, Sgouris P. Ward, John L. Civil and Environmental Engineering Engineering Systems Division 1-163 Massachusetts Institute of Technology 77 Massachusetts Avenue Cambridge MA 02139 United States Technology Management and Policy Program Engineering Systems Division 1-151 Massachusetts Institute of Technology 77 Massachusetts Avenue Cambridge MA 02139 United States

The complex large-scale integrated open systems (CLIOS) process is an overarching mechanism for considering systems, especially those exhibiting nested complexity, in which both the physical and the institutional aspects are complex. A special case of the CLIOS process is regional strategic transportation planning. New technologies, such as intelligent transportation systems, allow consideration of the planning, management, operations, and maintenance of transportation systems at the regional scale. Although the technological issues in advancing to this scale have proved tractable, the institutional issues concerned with deploying these systems across political jurisdictions with different measures of performance and different cultural perspectives has proved quite difficult. This paper explores processes for studying these institutional questions and integrating a number of concepts into the process: technological change, sustainability, real options, supply chain management, the various transport modes, and social, political, and economic factors. The paper serves as a case study of tailoring the CLIOS process into a process specifically designed to systematically address particular issues, in this case, regional strategic transportation planning.

Stakeholder-assisted modelling and policy design process for environmental decision-making

Journal of Environmental Assessment Policy and management 2005年第3期7卷 355-386页

作者： Mostashari, Ali Sussman, Joseph Technology Management and Policy Program Engineering Systems Division Massachusetts Institute of Technology Cambridge MA 02142 United States Department of Engineering Systems and Civil and Environmental Engineering Massachusetts Institute of Technology Cambridge MA 02142 United States

Environmental planning and policy analysis, design and implementation are complicated by the fact that environmental problems are almost always part of a complex sociotechnical system, the behaviour of which is not intuitive. The complexity of the problem necessitates a technical and scientific analysis process, which by its nature excludes the majority of the stakeholders in the given problem. To overcome these challenges, this research proposes the engagement of stakeholders from very early on in the process using computer-assisted visualisation and representation of complex sociotechnical systems. Specifically it proposed the use of system dynamics simulation in illustrating the complex interactions of the different sociotechnical system elements. Using computer simulation of the system, stakeholders can then decide on the best strategies to address the issue on a more objective basis. Ubiquitous computing enables the assessment of a vast number of strategies in a relatively short time. © Imperial College Press.

Motive, form and function of international R&D alliances: Evidence from the Chinese IT industry

引用

Journal of High Technology management Research 2005年第2期16卷 173-191页

作者： Wu, Jian Callahan, John Carleton University Telecommunications Technology Management Program Department of Systems and Computer Engineering 1125 Colonel By Drive Ottawa Ont. K1S 5B6 Canada

This article adds to the research literature on international R&D alliances by focusing on alliances formed by multinational corporations with Chinese organizations. Using publicly available information, we developed a sample of 80 international R&D alliances between multinational corporations and Chinese organizations in the information technology industry in China formed during the period from 1997 to 2003. We use these data to test hypotheses on the connections between the declared motives, organizational form and R&D activity function of such alliances. Our analysis shows that the two most frequent motives of multinational corporations when establishing R&D alliances with Chinese organizations are establishing vertical linkages and obtaining human resources. Within the context of a strong preference for non-equity-based cooperative agreements, our analysis also provides some evidence for an association between the choice of form and motive, strong evidence for an association between function and motive, and strong evidence for an association between the form and function. © 2005 Elsevier Inc.
