It is very important to a company to select the best program based on its needs, especially there are hundreds of programs, similar in general, different in price and functions. Many companies do only comparing between those programs, trying to select the best on this comparison. This article...

Expert systems are built with the help of: specialised programming languages or expert system generators (shell). But this structure was reached after tens of years of work and research, because expert systems are nothing but pragmatic capitalisation of the results of research carried out in...

The integration of computer applications into industrial enterprises is imposed by the necessity of real-time decision making in order to meet the frequent changes within a business environment. In this paper, we have tried to identify the impact that IT has on production management as well as...

A variety of algorithms have been proposed to solve the bicriterion shortest path problem. This article analyzes and compares the performance of three best-first (label-setting) algorithms that accept heuristic information to improve efficiency. These are NAMOA∗, MOA∗, and Tung & Chew’s...

A physical–empirical model is designed to describe heat transfer of helical coil in oil and glycerol/water solution. It includes an artificial neural network (ANN) model working with equations of continuity, momentum and energy in each flow. The discretized equations are coupled using an...

We consider generalized monotone functions f: X -- {0,1} defined for an arbitrary binary relation = on X by the property x = y implies f(x) = f(y). These include the standard monotone (or positive) Boolean functions, regular Boolean functions and other interesting functions as special cases. It...

A tanulmányban a Weka adatbányászati szoftver használata és a szövegosztályozás alapelvei kerülnek bemutatásra. Egy gyakorlati példán keresztül, amiben Internetről letöltött 4000 db ingatlanhirdetési szöveget dolgoztam fel, több szövegosztályozási módszert megvizsgáltam....

One of the key factors of a successfully implemented mixed-model line system is considering model sequencing problem as well as the line balancing problem. In the literature, there are many studies, which consider these two tightly interrelated problems individually. However, we integrate the...

Uno de los sectores económicos estratégicos más importantes en cualquier economía es el Mercado de Energía Mayorista, cuya característica fundamental es que se trata de un mercado oligopolístico, provocado por la barrera de entrada que supone tener economías de escala. De esta manera,...

Short-term load forecasting (STLF) in buildings differs from its broader counterpart in that the load to be predicted does not seem to be stationary, seasonal and regular but, on the contrary, it may be subject to sudden changes and variations on its consumption behaviour. Classical STLF methods...
