摘要:

The World Wide Web (WWW or Web) is a major new setting for Decision Support Systems (DSS) development, product information and research. This article documents and provides a structured summary of a wide variety of DSS resources available on the Web. This summary is targeted at MIS/DSS researchers and practitioners interested in designing, developing and implementing enterprise—wide DSS. It includes Web addresses for more than 60 key DSS—related Web sites. Seven major topics are discussed: searching the Web for DSS links; Web sites of DSS companies; University DSS Web sites; DSS accessible on the Web; DSS case studies available on the Web; DSS articles available on the Web; and general Web sites on topics related to DSS.

摘要:

The integrated resource planning methodology specifically compares supply—side options with demand—side options on an equal basis and includes all costs to society, including environmental cost, to determine the most appropriate selection of options for the best satisfaction of societal needs. Traditional methods for determining choices, particularly those which are intuition-based, are no longer adequate. For the integrated resource planning process to achieve the most appropriate outcome for society, many decision—making criteria need to be evaluated. This paper demonstrates that the adaptation of multicriteria- based methods to integrated resource planning assists energy policy makers while dealing with a range of, and often conflicting, objectives.

摘要:

We present an information and communication system for managing civil crises. In managing information, we take into account the opinions and intentions of the different actors exchanging information. We introduce the notion of the act of communication for representing the meaning and value of exchanged information. We use a multi—agent modélisation, having the properties of self—modification and self-generation, according to the meaning of the exchanged information. We then present an artificial interpretation process on the meaning of the exchanged messages.

摘要:

During the last 10 years, urban storm drainage has been confronted with very radical changes which are partially due to the use of new technologies such as ≪ alternative techniques ≫. Contrary to the traditional sewer network, these techniques are part of urban areas. They are numerous and offer a large amount of possibilities in terms of shape and functioning. At least, they are multifunctional so that they are not only devoted to storm drainage purposes. Consequently, they require competences which are much more widespread than those required for design, construction and management of traditional works. This paper presents a complete multicriteria decision—aiding model and associated tools aiming at helping to choose, design and select alternative strategies.

摘要:

Empirical studies have measured the effectiveness of decision support systems (DSSs) through a number of variables relating to: (a) the process of decision making or (b) the outcome of such decision making. Few studies have examined effectiveness with both types of variables. Further, empirical studies measuring the effectiveness of DSS have reported equivocal, or even dysfunctional results. This paper examines the relationship between the process and outcomes of decision making through using a DSS. First, it overviews the decision making process, identifies the role of a DSS in improving decision making, and develops a general model of DSS effectiveness. Illustrating with empirical studies, this effectiveness model is used to reconcile the incongruity between the experimental findings and the case—supported theory. The paper concludes with a discussion of the article's implications for information systems research.

摘要:

The work reported in this paper is an attempt to build upon existing research in the DSS area in order to enable the accurate measurement of the degree and extent of DSS usage in organisations. We put forward a framework for the classification of DSS usage which uses two dimensions, the novelty and specifiability of decision situations. This framework can be used by IS researchers to classify DSS applications meaningfully and make comparisons not only across large samples of systems, but also across organisations. In order to prove the validity of our novel approach, we studied and classified 24 Irish organisations based on the extent to which they used DSS for different decision situations using two specific measurements: DSS spread and DSS complexity. The results obtained confirm our initial empirical results (obtained with a smaller sample of organisations). The framework we have developed is a useful vehicle for categorising the extent to which organisations have managed to integrate their DSS staff and DSS applications in the decision making processes of managers at all levels.

摘要:

Decision aids are computer systems intended to help decision makers select from a set of alternatives when considering multiple criteria. There are a number of basic ideas behind such systems, including multiattribute utility analysis, analytic hierarchy process, and outranking. Some systems focused on identification of decision maker preference functions. Recently there have been a number of systems focusing on the idea of enhancing decision maker learning. This paper reviews the fundamental ideas of a number of decision aids and considers the cognitive effort on the part of decision makers required to use each system. Recent empirical studies from a number of sources are reviewed and evaluated for support of theories about this cognitive effort, as well as how learning systems are implemented.

摘要:

A major problem in research in Man—Machine Interactions is to develop the methods to model the tasks of an operator supervising a complex dynamic sytem. We propose a design and evaluation methodology which specify the steps wich lead to a system which is truly centred about operator's task and the technical and ergonomics design and evaluation of the supervision system. The formula of an operator's task is based on a confrontation between two models: a model of his possible behaviour and a model of his actual behaviour. The result is a model which explains the behaviour of operator. The model is described by graph theory (SADT and synchronized Petri nets) which gives a simple and formal tool directly usable by the designer. This conceptual model is then exploited for the specification of the displays. An example of application is given in the actual context of air trafic control work station.
