Some Considerations About Collaborative Systems Supporting Knowledge Management in Organizations

MUNTEAN, MIHAELA I.; TÂRNĂVEANU, DIANA - Volkswirtschaftliche Fakultät, … - 2009

In the present global economy, strongly influenced by IT (information technology) and information systems evolution, the modern organizations try to face the challenges by adjusting their strategies and restructuring their activities, for aligning them to the new economy requirements. It is...

Digital divide – inequalities in level of implementation of new information and telecommunication technologies. Cross country study.

Ewa, Lechman - Volkswirtschaftliche Fakultät, … - 2010

In the paper presented, the author considers few aspects of the so-called “digital divide”. It is easily noticeable worldwide, that new information and communication technologies (ICTs) “possess” a great ability to spread, at high pace, among countries from all around the world. At the...

Crisis Management and Political Decision Making Using Genetically Evolved Fuzzy Cognitive Maps

Andreou, A. S.; Mateou, N. H.; Zombanakis, George A. - Volkswirtschaftliche Fakultät, … - 2003

This paper examines the use of Fuzzy Cognitive Maps (FCMs) as a technique for modeling political and crisis situations and supporting the decision-making process. FCMs use notions borrowed from artificial intelligence and neural networks to combine concepts and causal relationships, in the form...

Coevolutionary Genetic Algorithms for Establishing Nash Equilibrium in Symmetric Cournot Games

Protopapas, M.K.; Kosmatopoulos, E.B.; Battaglia, F. - Volkswirtschaftliche Fakultät, … - 2009

We use co-evolutionary genetic algorithms to model the players' learning process in several Cournot models, and evaluate them in terms of their convergence to the Nash Equilibrium. The ``social-learning'' versions of the two co-evolutionary algorithms we introduce, establish Nash Equilibrium in...

Minimization of Keane’s Bump Function by the Repulsive Particle Swarm and the Differential Evolution Methods

Mishra, SK - Volkswirtschaftliche Fakultät, … - 2007

Keane’s bump function is considered as a standard benchmark for nonlinear constrained optimization. It is highly multi-modal and its optimum is located at the non-linear constrained boundary. The true minimum of this function is, perhaps, unknown. We intend in this paper to optimize Keane’s...

Adaptive agents in the House of Quality

Fent, Thomas - Volkswirtschaftliche Fakultät, … - 1999

Managing the information flow within a big organization is a challenging task. Moreover, in a distributed decision-making process conflicting objectives occur. In this paper, artificial adaptive agents are used to analyze this problem. The decision makers are implemented as Classifier Systems,...

Wissen gewinnen und gewinnen durch Wissen

Fent, Thomas - Volkswirtschaftliche Fakultät, … - 2000

According to Alfred Korzybski (1921) humans unlike plants and animals have the property to bind time, i.e. they are able to transfer experience through time. Humans are capable to collenct knowledge from the past and communicate their knowledge to the future. This paper investigates the...

Using Genetics Based Machine Learning to find Strategies for Product Placement in a dynamic Market

Fent, Thomas - Volkswirtschaftliche Fakultät, … - 1999

In this paper we discuss the necessity of models including complex adaptive systems in order to eliminate the shortcomings of neoclassical models based on equilibrium theory. A simulation model containing artificial adaptive agents is used to explore the dynamics of a market of highly...

Repulsive Particle Swarm Method on Some Difficult Test Problems of Global Optimization

Mishra, SK - Volkswirtschaftliche Fakultät, … - 2006

In this paper we test a particular variant of the (Repulsive) Particle Swarm method on some rather difficult global optimization problems. A number of these problems are collected from the extant literature and a few of them are newly introduced. First, we introduce the Particle Swarm method of...
