The objectives of this research are to develop a knowledge-based group decision support system for site selection and to explore the effectiveness of the system. The GDSS uses an enhanced Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to identify a small subset of candidate locations from the location database. A knowledge-based system (KBS) was created to check the degree of group consensus, which is determined by some fuzzy scalar measures. The output from the KBS shows the performance of group commitment on the weighting of location factors. The decision makers are then requested for further evaluating the candidate locations via computer-mediated group discussion. To evaluate the performance of the KBS in the GDSS, an empirical study was designed and implemented. The results show that GDSS supported groups using both TOPSIS and KBS enhancements had better outcomes than GDSS supported groups using only TOPSIS enhancement.

Israel Conference on Computer systems and Software engineering

作者： P. Shoval O. Feldman Information Systems Program Department of Industrial Engineering and Management Ben-Gurion University of the Negev Beersheba Israel Department of Mathematics and Computer Science Ben-Gurion University of the Negev Beersheba Israel

The study proposes a combination of the function points model for software estimation with the ADISSA methodology for systems analysis and design. This combined approach, which is supported by a software tool, enables one to estimate various software metrics, such as size, effort, and duration, in the early stages of systems development, by basing them on the products of a thorough system analysis and design process.

In addition he has presented research papers served as both a reviewer and discussant chaired sessions and tracks and participated in program committees of several regional national and international conferences.

Current economic conditions are forcing information system departments to focus simultaneously on decreasing costs while increasing software productivity. Improving software productivity is becoming critical because software costs of large in-house software companies have been increasing rapidly. For many organizations, however, measuring software productivity has been a difficult task. Using Data Envelopment Analysis (DEA), this research study investigates the productivity of 78 commercial system projects. The results of this study have practical implications for software project managers undertaking software development. The results showed that the DEA technology can be successfully used to identify efficient and inefficient software projects. Furthermore, within the inefficient group, DEA can also identify factors that affect software productivity in a positive or negative manner, allowing managers to take corrective actions. Based on the findings of this study, the manuscript also provides some practical guidelines for managers to follow in software development.

The Fleet continues to require high performance systems that can operate with dependability in the seas' unforgiving environments and under hostile action. Those demands are not new. What has changed is the urgent priority formerly assigned to national defense issues. The arguments for continued superpower military strength are now roiled in politics along with unsettled budgets and uncertain force level projections. Current expectations revolve about indefinite fiscal and operational issues (difficult funding constraints and broadband threats). In the actual event of ''doing more with less,'' a practical response is to apply the creative power available from sound engineering judgement and the crucible of experience to the immediate needs of the Fleet. The attempt to shorten the path between advanced development effort and Fleet use has been tried occasionally in the past, often, without exemplary results. The Sustainable Hardware and Affordable Readiness Practices (SHARP) program, is a generic R&D effort under OpNav sponsorship that has been working steadily on sensible solutions to product engineering problems. Armed today with fast-time, large-scale computation abilities and modern tools for technical problem solving coupled with specialized engineering knowledge, it has been refreshed and is underway satisfying existing Fleet needs. The relationship between fully responsive engineering services and current operational needs is always demanding. The connection between advanced engineering development (6.3 category funds) and immediate Fleet usage brings added complexity and challenge, both technical and organizational. Illustrative examples of affordable engineering solutions to ''retain, revise, replace or retire'' questions are presented within the context of both Fleet realities and budgetary limitations. The discussion covers legacy system support, civil/military considerations and Fleet maintenance issues. It describes the substantial and critical payoffs i

This paper describes the design of a Regional Deterrence Ship (RDS 2010) for the 2010 timeframe. The requirements for the design were for a ship to operate in littoral areas of the world with a mission of deterring regional conflicts and of hampering the efforts of the aggressor in such a conflict. In addition the ship's mission included the evacuation of friendly personnel as hostilities become likely. The problem countering the littoral threat during times of constrained budgets is addressed. Top level requirements for the design, generated in parallel with ''.... From the Sea'' [1], were used to set the design goals. The paper describes the manner in which littoral warfare changes the nature of the challenges faced by Navy surface combatants, including a ship such as the RDS 2010. A number of factors become more crucial design concerns than for blue water ships, including reduced reaction times, likelihood of attack from hidden land sites, shallow water mines and shallow water USW Certain other factors become less critical in littoral areas and this also has ship design impacts. While some present ship designs can perform some of the tasks needed in a littoral warfare/regional conflict environment, none represents a completely integrated design (hull, mechanical & electrical;combat systems;fiscal and manning constraints;reduced vulnerability;robust self-defense etc.) for a vessel stationed in waters that, without warning, can become hostile. After describing the mission requirements to which the RDS 2010 was designed, the paper discusses the controlling design philosophy and decisions and describes the process used to assess threats to the ship. The process of combat system selection, against the backdrop of expected threat scenarios, is described and the intended approach to integration of the combat system is discussed. In recognition that decreased reaction times and surprise attacks are likely to threaten a ship engaged in regional deterrence, discussions oi

INFORMATION AND SOFTWARE TECHNOLOGY 1995年第2期37卷 79-85页

作者： SHOVAL, P Information Systems Program Department of Industrial Engineering and Management Ben-Gurion University of the Negev Beer-Sheva 84105 Israel

This paper describes a structured method for designing subsystems from a whole system, which extends ADISSA methodology for systems analysis, design and prototyping, The design of a subsystem includes: (a) definition of the transactions, or processes, that belong to the subsystem, thus determining the boundaries of the subsystem;(b) design of the subsystem user-interface, a sub-menu-tree, derivable from the menu-tree interface of the global system;and (c) design of the database sub-schema, derivable from the global database schema. The method is supported by a CASE tool, enabling automatic and interactive design and prototyping of the subsystems.

Training is often the performance improvement solution of choice, yet how often does the best training not yield performance improvement? There is a growing body of evidence that indicates that many times performance improvement can be achieved faster, cheaper, and better by altering factors in the workplace than by training. This article describes an activity designed to illustrate the importance of workplace factors in improving performance and a study that demonstrates its validity. Results of the study indicate that two‐thirds of the participants believed the environmental factors of information, resources, and incentives needed improving in order to enable them to improve their own performance.

Stiff diagrams arc a multivariate method of analysis used to describe the chemical state of ground water. The use of Stiff diagrams to describe multiconstituent contamination sites, such as landfills, has distinct advantages over single constituent analyses. Problems associated with traditional Stiff diagram analyses, such as diagram attentuation, can be addressed by allowing the scale of the diagram to vary with the ionic strength of the analyzed sample. The use of these sliding scale Stiff diagrams reveals the chemical slate of the ground water over wide ranges of constituent concentrations and thus allows for sensitive and sophisticated depictions of complicated contamination sites in a fashion that is extremely difficult to replicate with single constituent analyses. This approach has possible applications for understanding and tracing the mixing and chemical changes in uncontaminated settings. Copyright © 1995, Wiley Blackwell. All rights reserved

While the end of the Cold War minimized the threat of open ocean naval combat, new littoral warfare missions and threats such as tactical ballistic missiles have emerged. These threats and missions challenge the traditional military standard computing resources available to the Navy--a challenge that is increasingly difficult to meet in a cost effective manner. Furthermore, in recognition of the high cost of military standards, Secretary of Defense William Perry has directed that commercial standards be utilized wherever possible. As a consequence of this changing environment, the Aegis shipbuilding program has begun efforts to replace current military standard computing equipment with both higher performance commercial equipment and newer system architectures, i.e. distributed computing. As a part of this process, the Aegis program Office has collaborated with the Advanced Research Projects Agency (ARPA) to conduct a joint experiment on the feasibility of inserting a number of ARPA-developed distributed computing technologies into the Aegis combat system, The High Performance Distributed Computing program (HiPer-D) was created from this joint initiative. The overall objective of HiPer-D is to validate distributed computing for Navy shipboard combat system applications. This paper presents the results of the first HiPer-D demonstration of commercial computing technology as applied to the Aegis combat system.

An architecture of an intelligent system for routing user requests in a network of heterogeneous databases

引用

Journal of Intelligent Information systems 1994年第2期3卷 205-219页

作者： Giladi, Ran Shoval, Peretz Information Systems Program Dept. of Industrial Engineering and Management Ben-Gurion University of the Negev Beer-Sheva 84105 Israel

We present a general purpose model for routing user requests, e.g. queries, in a network of autonomous heterogeneous databases. The database schemas and other information on the database nodes are used to construct a multi-level knowledge-base (MKB) that resides in various nodes. Access to the databases is not done by creating direct connections between the user and the nodes where the data are presumably located. Rather, the user approaches the network by contents via an intelligent system that utilizes the MKB in order to identify the nodes and databases where the most relevant information resides, and establishes access routes to those nodes. © 1994 Kluwer Academic Publishers.
