Bidder selection in public procurement is a decision making problem whose primary purpose is to achieve the cost effectiveness and efficiency in the expenditure of public money. This principle is also known as the principle of “value for moneyâ€. This selection is based on many...

Due to globalization, companies are frequently pushed to grow outside their political and geographical boundaries, forcing them to increase product diversification. As a side effect they can also optimize their resource's management by looking at potential businesses for improving their...

This article presents a multi-goal solver for problems that can be modeled using a Blackboard Architecture. The Blackboard Architecture can be used for data fusion, robotic control and other applications. It combines the rule-based problem analysis of an expert system with a mechanism for...

While online conversations are very popular, the content generated by participants is very often overwhelming, poorly organized and often of questionable quality. In this article we use two methods, a text analysis technique, Vector Space Modeling (VSM) and clustering to create a methodology to...

In this article, the authors propose a new framework called the MAGDM-Miner, for mining correlation rules from trapezoidal intuitionistic fuzzy data efficiently. In the MAGDM-Miner, the raw data from a Multiple Attribute Group Decision Making (MAGDM) problem with trapezoidal intuitionistic fuzzy...

This article presents a participatory design approach to Decision Support Systems, which is specifically built to face the socio-technical gap that often impedes DSS acceptability by end-users in real work environments. The approach has been experimented in two case studies in the field of...

Methods for group decision analysis are based on various preference and aggregation models, and may exhibit a significant level of complexity that is perceived by decision-makers. It is therefore essential to apply appropriate methods and keep the complexity within controllable limits. In the...

Sizing the capacity of a call center is a well known problem. However, in some cases there are regulatory aspects that must be observed that, combined with specificities of the service provided and how it operates, affects the manner of the process for forecasting the inbound call rate and...

Quantitative analysis of negotiation concession behavior is performed based on empirical data with the purpose of providing simple and intuitive decision support in electronic negotiations. Previous work on non-linear concave preferences and subsequent concession crossover provides a theoretical...

This study develops a model for selecting a host for a travel show. First, the proposed model adopts the “Modified Delphi Method†to find out suitable criteria to evaluative hosts of travel shows. Next, the research model applies the “Analytic Hierarchy Process (AHP)†to...
