Analysis of multiple criteria decision support systems for cooperative groups

This article reviews research on multiple criteria decision support systems for cooperative groups. The systems included in this survey integrate concepts from group decision theory, multiple criteria decision methodology, and decision support system technology. Three dimensions are considered in the analysis of existing research: the multiple criteria decision technique used to generate decision alternatives or to choose from a given set; the method used to facilitate individual compromise and group consensus; and the application category, if any.     

Cognitive hurdles in the use of decision support systems to enhance problem understanding

Computer-assisted decision support systems have been widely promoted as a means of enhancing problem understanding in crisis and noncrisis decision making. Clinical observation of actual applications of a particular category of software for interactive decisions (CONAN, DECISIONMAKER) have identified cognitive hurdles in the use of such systems. These hurdles not only pose a challenge to the development of such normative interventions in the decision process, but also an opportunity for furthering the shift to a new psychologically informed paradigm for decision making.     

A framework for interactive multiple criteria group decision support

An interactive framework is developed for multiple criteria group decision support. Decision makers are asked to specify aspiration and reservation levels to establish a preferred range for the value of each objective for each decision maker. Group and individual solutions are generated as a function of these levels. Decision makers are asked to react to current solutions by revising their aspiration and reservation levels and additional solutions are generated. The framework is both simpler and more flexible than previous approaches.     

An object-oriented architecture for group decision support systems

An object-oriented GDSS can produce a rich environment for easily accessing software tools or applications running under a Graphical User Interface and can provide communication among meeting participants. This requires definition of (1) objects to manage the meeting and participant sessions, (2) applications that can run under these sessions, and (3) data storage and data communications capability that handle both private and shared data. This article suggests that a GDSS system can operate under three layers of software: an application-layer, a GDSS environment, and an operating system environment. It defines the structure and behavior of the GDSS environment layer in terms of (1) objects and messages used to communicate among these objects and (2) a message passing protocol between the GDSS environment and the other two layers. These specifications result in an architecture that is sufficiently modular to enable addition of various GDSS software. This article also discusses a prototype implementation of the architecture that is developed in Smalltalk and runs under Microsoft's Windows 3.0.     

Decision making and decision aiding: Defining the process,it representations,and support

We present a formalized account of decision making as a multistep process that involves several classes of participating entities. The purpose of this article is to lay the foundations for a conceptual framework in which decision support systems can be placed. A series of increasingly formal representations of the decision problem are developed, from a mental model conceived by the decision maker to a knowledge base that may be used in a decision support system. The reformulations of the decision problem lead us to contemplate different forms of support: for mental models, for formal models (this includes supporting measurement and representation), for solution, and for communication.     

INTERACT: Developing software for interactive decisions

This paper describes the development and use of a piece of software, INTERACT, for analyzing situations under the control of several interested parties. After briefly discussing forms of analysis used, it outlines the design philosophy of the software itself. Particular attention is paid to its intended use in a decision support role. The functions typically performed in the course of analysis are illustrated using a worked example. Finally, avenues for further development are outlined.An earlier version of this paper was read at the Conference on Decision Making under Conditions of Conflict, University of Waterloo, Ontario, August/Sept 1992     

Evaluating a Framework for Multi-Stakeholder Decision Support in Water Resources Management

In this paper we describe a framework for multicriteria modeling and support of multi-stakeholder decision processes. We report on its testing in the development of a new water level management policy for a regulated lake-river system in Finland. In the framework the stakeholders are involved in the decision process from the problem structuring stage to the group consensus seeking stage followed by a stage of seeking public acceptance for the policy. The framework aims at creating an evolutionary learning process. In this paper we also focus on the use of a new interactive method for finding and identifying Pareto-optimal alternatives. Role playing experiments with students are used to test the practical applicability of a negotiation support procedure called the method of improving directions. We also describe the preference programming approach for the aggregation of the stakeholder opinions in the final evaluation of alternatives and consensus seeking.     

Decision making under conditions of conflict

A real-world application is employed to explain three general types of decision situations that can arise under conditions of conflict. In addition, meaningful connections and relationships among these areas of decision making are clearly pointed out. To permit useful decision technologies to be employed by practitioners for better understanding and for resolving a variety of actual decision problems, a range of flexible decision support systems is discussed. Subsequently, interesting research developments contained in the upcoming sequence of 12 articles on decision making under conflict are summarized and compared. The research articles not only present unique approaches to decision making involving multiple participants, each of whom may have multiple objectives, but suggest a variety of challenging research problems to be investigated in the future.     

Technology support for cooperative work: A framework for studying introduction and assimilation in organizations

This article draws on published research on the nature of the innovation process and exploratory field research in 10 companies to develop a framework for research on organizations’ introduction and assimilation of computer‐supported cooperative work technologies. The research reported in this article, part of a much larger study of the general process of innovation in organizations, focuses specifically on the transfer and assimilation of new technology innovations.

Technologies to support group process, communication, and coordination in face‐to‐face group meetings [electronic meeting support systems (EMSS)] were chosen to illustrate the use of the research framework. The article focuses on the transfer of these technologies from R“D units to target organizational units and the alignment of group, technology, and task during assimilation by end‐user groups. Research propositions are developed and discussed. Future articles will present the findings from current research that utilizes the frameworks presented in this article to study the introduction, transfer, and assimilation of EMSS in organizations.     

A model and case for supporting participatory public decision making in e-democracy

In this paper, focusing on participatory public decision making processes, I propose a framework for group support systems and discuss related research issues. As a case illustrating the feasibility of participatory public decision making, I present the participatory budgeting experience in Porto Alegre, Brazil. The case is analyzed based on the proposed framework.     

A novel framework for customer complaint management

Complaining is one option available to customers to express their dissatisfaction with inadequate services. Their complaints contain valuable information for service providers to improve customer relationships and operational quality, which can ultimately enhance business profitability. Customer complaints are frequently handled at the individual level, however, which addresses the symptoms rather than the causes of customer dissatisfaction. This paper presents a framework integrating a decision tree approach, a common data mining tool, into Six Sigma methodology to analyze customer complaints in aggregate and improve service quality by identifying and addressing the underlying causes of failed service. A case study of a restaurant chain was used to demonstrate the effectiveness of the proposed framework. The results indicated a significant (60%) decrease in the number of customer complaints received. Subsequent long-term benefits can be expected.     

Critical Situations for Decision Making: A Support Based on a Modelling Tool

This paper proposes to give a toll to help decision makers in critical situations. The principle of our research is based on a modelling approach for Cooperative Knowledge Based Systems. This approach is based on a Task/Method paradigm that we describe. We then propose to take into account collateral effects of tasks in order to support decision makers in a critical context. The proposed tool can then generate a degraded solution for which, collateral effects of previous tasks have been taken as new goals to reach. This study is possible thanks to the definition of several kinds of models: a Good Functioning Model and a Degraded Tasks Library.     

Cultural Dimensions and Prototypical Criteria for Multi-Criteria Decision Support in Electronic Markets: A Comparative Analysis of Two Job Markets

Electronic markets are virtual meeting places where buyers and sellers interact to trade products or services. The main motivation for both buyers and sellers to participate in an electronic market is the desire to maximize their private utility (Bakos 1998). Electronic markets therefore usually provide some form of communication, decision or negotiation aid for buyers and sellers to support their utility maximizing goals. This paper presents a comparative analysis of two electronic job market case studies conducted at a university in Europe (Brussels, Belgium) and in the United States (Newark, New Jersey). At the occasion of the universities’ career fairs, students (n = 392) and local companies (n = 57) were invited to participate in an electronic job market to identify the best job offers (n = 137) and students, respectively. Participants were able to create personalized software agents to aid their search and decision making activities in the market. Every software agent was embedded with a multi-criteria decision support tool to produce a rank ordered list of students or job offers. Preference data gathered from market participants’ use of the multi-criteria decision model allow us to construct relational preference structures using a technique based on the mathematical theory of fuzzy relations (Bandler and Kohout 1980). These preference structures express relationships among the criteria that students and companies have used to identify job offers and companies, respectively. The purpose of the paper is to present the communicative and cultural implications of these relational preference structures. The theories of Hofstede (1983), Hall (1977) and Trompenaars (1993) on cultural dimensions allow us to discuss cultural differences on the choice of prototypical criteria. The paper concludes with implications for the use of electronic markets in the staffing industry and the role of software agents in such job markets.
