This article is dedicated to the development of time series forecasting scheme. It is created based on the forecasting models system that determines the trend of time series and its internal rules. The developed scheme is synthesized with the help of basic forecasting models "competition" on a certain time interval. As a result of this "competition", for each basic predictive model there is det...

The technology revolution lead by Internet and ever improving computing power has played pivotal role in justifying the sense of a global village perception. Managing and enabling technological growth is among the top priorities of the organizations today. To meet this priority, organizations must create reliable, secure and cost-effective infrastructures that enable business innovation. Techno...

This paper proposes a modified Genetic Programming method for forecasting the mobile telecommunications subscribers’ population.Themethod constitutes an expansion of the hybridGenetic Programming (hGP)method improved by the introduction of diffusion models for technological forecasting purposes in the initial population, such as the Logistic, Gompertz, and Bass, as well as the Bi-Logistic and L...

Introduction Forecasting demand is both a science and an art. Econometric methods of forecasting, in the context of energy demand forecasting, can be described as ‘the science and art of specification, estimation, testing and evaluation of models of economic processes’ that drive the demand for fuels. The need and relevance of forecasting demand for an electric utility has become a much-discuss...

A number of radically distinct models (inquiry systems) are described. The models derive from C. West Churchman’s recent characterization of the history of Western epistemology. It is argued that only a few of these models are appropriate for technological forecasting problems. Most technological forecasting methodologies rest on a dubious philosophical foundation. They unreflectively assume th...

This paper concentrates on asymptotic properties of determinants of some random symmetric matrices. If Bn,r is a n × r rectangular matrix and B′ n,r its transpose, we study det(B′ n,rBn,r) when n, r tends to infinity with r/n → c ∈ (0, 1). The r column vectors of Bn,r are chosen independently, with common distribution νn. The Wishart ensemble corresponds to νn = N (0, In), the standard normal d...

Rose, Jones and Truex (2005) offer a valuable discussion of the issue that has occupied center stage in IS research for decades: how to conceptualize the relationship between technology and organizations? They raise a number of important concerns with existing approaches to this issue, and by highlighting these limitations, Rose, Jones and Truex challenge us to rethink our cherished assumptions...
