This paper presents a case study where competitive e-learning strategies are used in the teaching of an undergraduate Database course in order to develop, in university students, the capacity to actively research and to lead their own learning process. The experience has been carried out in the spring semester (February-June 2007) and is based on the use of the QUEST system. This tool for activ...

By developing strategic configurations which describe commonly used paths to competitive advantage for manufacturers, this paper reconciles some basic concepts from competitive strategy and manufacturing strategy. Four basic strategic configurations are identified: niche diflerentiator, broad differentiator, cost leader, and lean competitor. The configurations are traced conceptually through co...

We integrate probability distribution into pure competitive analysis to improve the performance measure of competitive analysis, since input sequences of the leasing problem have simple structure and favorably statistical property. Let input structures be the characteristic of geometric distribution, and we obtain optimal on-line algorithms and their competitive ratios. Moreover, the introducin...

In this paper, based on the Position Maintaining Strategy (PMS for short), on-line scheduling of k-truck problem, which is a generalization of the famous k-server problem, is originally presented by our team. We proposed several competitive algorithms applicable under different conditions for solving the on-line k-truck problem. First, a competitive algorithm with competitive ratio 2k + 1/θ is ...

This paper gives an overview of some classical Growing Neural Networks (GNN) using soft competitive learning. In soft competitive learning each input signal is characterized by adapting in addition to the winner also some other neurons of the network. The GNN is also called the ANN with incremental learning. The artificial neural networks (ANN) mapping capability depends on the number of layers...

Five methods that generate multiple prototypes from labeled data are reviewed. Then we introduce a new sixth approach, which is a modification of Chang’s method. We compare the six methods with two standard classifier designs: the 1nearest prototype (1-np) and 1-nearest neighbor (1-nn) rules. The standard of comparison is the resubstitution error rate; the data used are the Iris data. Our modif...

The paper aims, in the field of manufacturing technologies, at approaching issues of manufacturing systems, in order to develop a new concept of management, which is in line with the current market dynamics: the concept of competitive management. The concept of competitive management can offer solutions even to make competitive and develop enterprises as a whole. However, improving competitiven...

The vast bodies of studies in the word and recently in Iran have attempted to investigate the manufacturing industry structure (indicating the level of industries in terms of monopoly or competitiveness) and its trend using the various indices and methods. Despite the importance of Lorenz Curve and Gini Coefficient in indicating the market structure, these methods, capabilities have been neglec...
