Previous experimental and game-theoretic analyses of deregulated electricity markets suggest that communities having four or less effective suppliers, either because of transmission constraints or load characteristics, or retail customers facing suppliers or marketing agents having more than seventy percent of the region's market, are likely to experience prices well above competitive levels. While state regulatory bodies may be able to forestall the onset of retail wheeling and non-regulated retail energy pricing until a single supplier does not dominate initial market shares, it is more difficult to mute the exercise of market power by generators serving electrically isolated load pockets. And in both instances, if the accrual of some excess profits by initial, non-regulated suppliers are not tolerated, then little incentive will have been provided for competitors to enter the market and for more efficient technologies to evolve. Estimates are provided in this analysis of the circumstances for and the extent and duration of the exercise of market power. When combined with the present absence of incentives to build transmission lines that would reduce bottlenecks and the existing utilities' insistence upon full recovery of stranded costs through line charges and access fees, the powerful incentives to develop distributed generation are highlighted.

This paper studies handoff control mechanisms for mobile ATM networks with private network-network interface (PNNI) hierarchical structure. In this paper, we propose a hierarchical rerouting (HRR) scheme for handoff control which utilizes the PNNI routing information during the path rerouting procedures. The scheme can identify the crossover switch (COS discovery) in a hierarchical fashion, so that the additional signaling delay for the handoff control becomes scalable to the size of the network. Compared with previously available flat rerouting (FRR) schemes, the HRR scheme can effectively reduce the processing time for COS discovery in a PNNI network and, therefore, reduce the handoff latency. Experimental results are obtained using a PNNI network simulator and the performance of typical path rerouting algorithms is evaluated.

Many transportation providers such as package delivery companies and postal service organizations face the problem of designing a transportation network in order to service their customers. This network must balance the requirement of customers delivery under tight time window constraints with the goal of low-cost operations of the fleet. Until recently this task was usually performed by planners without sufficient software aid. This paper describes a decision support system (DSS) which has been designed in order to assist planners of the German postal service, the Deutsche Post AG. It helps the planners in designing improved plans which can be generated either manually or with the help of sophisticated intelligent optimization techniques. Both optimization and system design factors, which influenced the design of the DSS are classified.

The design, analysis and development of parallel and distributed applications in High Performance Computing and Communication (HPCC) Systems are still very challenging tasks. Therefore, there is a great need for an integrated multilevel analysis methodology to assist in designing and analyzing the performance of both existing and proposed new HPCC systems. Currently, there are no comprehensive analysis methods that address such hierarchical modeling approach for analyzing the end-to-end performance of an application running on an HPCC system. The overall system is partitioned into application level, protocol level and network level. Functions at each level are modeled using queueing networks. The approach enables the designer to study performance for different types of networks and protocols and different design strategies. In this paper we use video-on-demand as an application example to show how our approach can be used to analyze the performance of such an application.

The authors report on the development and testing of an interactive software aimed at enhancing the quality of decisions made by nonprofit community based organizations (CBOs). Preliminary findings shed some light on the extent to which computer assisted management and communication technologies may contribute to the accomplishments of CBOs, the effectiveness of their programs, their ability to inform policy, and their chances of obtaining financial support. Also, the early findings suggest that it is possible to bring about positive change in communities by empowering grassroots entrepreneurs and the organizations they lead with the appropriate technologies.

The paper describes usability evaluation of a prototype archive in a project where SGML-based solutions for the Finnish Parliament and ministries have been developed and studied. The archive consisted of three types of parliamentary documents in SGML format. A usability inspection was preceded by an extensive analysis of the document management in the Finnish legislative and budgetary work. The analysis covered the documents, their use, user roles, tasks, and needs. The inspection method was tailored from an earlier design-oriented evaluation method to be used especially for the evaluation of structured document archives. A grammar-based layered model was used to facilitate the detailed analysis of the application. In the paper we discuss implications of the study to the future design, implementation and evaluation of structured document archive application.

This paper is concerned with the evaluation and improvement of resource allocation. As a result of the dynamic environment in which organizations have to survive, resources have to be reallocated frequently in order to maintain organizational performance. In this paper we present a case study which was conducted at the Dutch Internal Revenue Service. The purpose of this case study was to find out to what extent a decision model could be developed to support their allocation problems. The analysis resulted in a prescriptive model to evaluate effort dedicated to tax audits, and to estimate the probability of increased tax revenues as a result of different resource allocation schemes.

Rational Rose is a graphical software modeling tool, using the Unified Modeling Language (UML) as its primary notation. It offers an open API that allows the development of additional functionality ("add-ins"). In this paper, we describe Rose/Architect, a Rose/sup TM/ "add-in" used to visualize architecturally-significant elements in a system's design, developed jointly by University of Southern California (USC) and Rational Software Rose/Architect can be used in forward engineering, marking architecturally significant elements as they are designed and extracting architectural views as necessary. But it can be even more valuable in reverse engineering, i.e., extracting missing key architectural information from a complex model. This model may have been reverse-engineered from source code using the Rose reverse engineering capability.

This paper implements a power flow application and variations using the IEEE Power System Application Data Dictionary within a Matlab environment. It describes a number of useful data and implementation techniques for a variety of applications. The techniques include the use of very compact and efficient code for the computation of Power Transfer Distribution Factors. Power Transfer Distribution Factors are all important element of present and proposed congestion management strategies for power systems, particularly, when these systems must operate in a deregulated environment.

The paper reports on the preliminary findings of an in-depth case study of the implementation of a computerized order entry (COE) system at a medium sized, acute care hospital. We propose a theoretically grounded framework, based on work by S.R. Barley (1986; 1990), for analyzing organizational changes that may result from COE introduction and use the framework to analyze findings at the research site. The hospital studied was largely successful in implementing and utilizing the system. However, use of the COE has altered the content and structure of order related information that passes between key participants in clinical care, affecting how these occupational groups and departments communicate and interact by creating ambiguity and uncertainty about order information. Use of the system may also be enabling increased organizational control over clinical care practices, exercised through professional norms and the clinical administrative hierarchy. Findings were consistent with other studies of COE use, suggesting that future research could focus on the consequences of structuring the content of order related communications on interactions between clinical and ancillary departments and the need to integrate the COE with other clinical systems to minimize disruptions.
