Decision Support Systems

This paper considers two important issues related to security risk management. First, the presence of network externalities in security risks. Second, the distinction of general (network) and system-specific protection measures. We found the optimal ...

We study the coordination of actions and the allocation of profit in supply chains under decentralized control in which a single supplier supplies several retailers with goods for replenishment of stocks. The goal of the supplier and the retailers is to ...

The acquisition process of consumer durables is a 'sequence' of purchase events. Priority-pattern research exploits this 'sequential order' to describe a prototypical acquisition order for durables. This paper adds a predictive perspective to increase ...

In this paper, we report results of an investigation into the factors influencing the selection of sponsored links by e-commerce Web searchers. In this research, 56 participants each engaged in six e-commerce Web searching tasks. We mined these tasks ...

The demand for family financial planning (FFP) services is growing dramatically as the financial market grows more complex and people become more aware of the importance of qualified financial guidance. To provide decision support for FFP-related ...

Previous research has shown that managers offered the opportunity to use MDSS perform better but are not more confident about their decision. The performance increase seems to result from a reliance effect rather than from a better understanding of the ...

This research establishes a dynamic game-theoretic model that interprets the mechanism of reputation feedback systems in online consumer-to-consumer (C2C) auction markets. Based on the model, a numerical study is conducted to reveal the effects of ...

Enrollment management is a process critical to many universities that rely on tuition for a significant portion of their operating budgets. This study describes how the development and implementation of a system to support decisions in the enrollment ...

When a firm implements analytical CRM, the value of a customer is assessed by profitability analysis. In a sense, a firm retains profitable customers but ''fires'' unprofitable ones. In this paper, we show that this typical customer selection strategy ...

Electronic Negotiation Support Systems allow users to construct a formal model of their preferences, which is then used during the negotiation process. In this paper, we analyze whether preferences embedded in such models are actually reflected in the ...

M. Yokoo et al. analyzed some weaknesses in McAfee's double auction (MCD) protocol and proposed a robust threshold price double auction (TPD) protocol against false-name bids. Unfortunately, as their protocol strongly depends on the trust of auctioneer, ...

The Internet has become the primary source of information for a large number of consumers. Thus, search engines as the mediators between consumers and online information is an increasingly important topic of research. The present study contributes ...

Compensatory adaptation theory makes two key predictions. On one hand, the theory predicts that electronic communication media in general will pose obstacles to complex communication between collaborators, when compared with the face-to-face medium, ...

Motivated by the practical significance of deception detection to both organizations and individuals and the recent surge of research interests in deception in computer-mediated communication (CMC), this study examines whether and how the modality of ...

In this paper, a framework which employs neural networks to plan the work breakdown structure of projects has been introduced. Using the proposed framework, a modular neural network has been developed to plan the structures of a limited project domain. ...

Decision tree methodology has become an increasingly important tool set in the field of decision science. We develop a multivariate, tree-based decision system for a new application: the determination of whether a newly launched consumer product should ...

There is much literature in the area of emergency response management systems. Even so, there is in general a lacuna of literature that deals with the issue of measuring the effectiveness of such systems. The aim of this study is to develop and validate ...

Effective decision making is based on accurate and timely information. However, human decision makers are often overwhelmed by the huge amount of electronic data these days. The main contribution of this paper is the development of effective information ...

The proliferation of newer agile integrative business information systems (IBIS) environments that use the software agent and the multiagent systems paradigms has created the need for a common and well-accepted conceptual modeling grammar that can be ...

This work presents a set of protocols for scheduling a meeting among agents that represent their respective user's interests. Four protocols are discussed: a) the full information protocol when all agents are comfortable with sharing their preference ...

This paper studies the formation of users' expectations and desires from knowledge management systems, and their impacts on satisfaction with these systems. Building on a foundation of expectations confirmation theory and interviews with top managers, ...

This paper introduces a new web-based decision support tool called Smart-Swaps to support multicriteria decision analysis. The decision maker's preferences are elicited with the even swaps method, which is an elimination process based on value trade-...

An increasing number of application areas now rely on obtaining the ''best matches'' to a given query as opposed to exact matches sought by traditional transactions. This type of exploratory querying (also called top-k querying) can significantly ...

The healthcare industry is experiencing a major transformation towards e-healthcare, which delivers and enhances related information through the Internet among healthcare stakeholders and makes the electronic signature (e-signature) more and more ...

In a recent paper Yao et al. present a single-buyer-single-supplier model to explore the effects of collaborative supply-chain initiatives such as vendor managed inventory (VMI). Several conclusions drawn from their model are arguable as (i) the model ...
