Problemy integracji aplikacji
pp. 7-16
Abstract: An application integration is a combination of problems. Each organization and trading community has its own set of integration issues that must be addressed. Because of this, it is next to impossible to find a single technological solution set that can be applied universally. Therefore, each application integration solution will generally require different approaches. Although approaches to application integration vary considerably, it is possible to create some general categories, which include: information-oriented, business process integration-oriented, service-oriented, portal-oriented. Key words: application integration, business process integration-oriented, service-oriented architecture, portal-oriented. Application integration

Problem wdrażania systemów ERP w handlu w warunkach polskich
pp. 17-24
Abstract: The article contains a short characteristics of the specific advantages of using IT systems in trade, mainly in retail trade chains, from the point of view of their cooperation with fiscal cash register. There have been described formal and functional requirements concerning software to collecting and transforming data from fiscal cash register. Full attention has also been paid to problems of using the software made by its users. One can find that it may be basic reason of slowly introducing of the ERP modern systems in retail trade chain on a bigger scale. Key words: ERP systems, fiscal cash register

Pierwsze dwa momenty oceny wariogramu
pp. 27-33
Abstract: In this article we deal with theoretical bases of geostatistic which have employment in research of time series. Let we have stationary random process, defined on R, with expected value equal 0, given covariance function and spectral density. For this process we define variogram function and prove two theorems about variogram estimator property Key words: variogram function, spatially variable data, modelling semivariograms, geostatistical methods

Model and Implementation of Self-Organising Neural Network for Searching Discovery in Databases
pp. 35-47
Abstract: This paper presents selected results of possibilities of building model of self-organising neural network using SPHINX language and NEURONIX Toolbox. By implementation used to algorithm Winner Take All (WTA) and Winner Take Most (WTM). For practical verification worked up example contains base date consist information about parameters of printers working in each departments of office. Databases contain knowledge related with characteristics of technical parameters each printer and their exploitation conditions. Neural Network used to discovery regularities in information consists of 20 input and 20 neurones. Examples contain about 200 training vectors. For implementation elaborated some functions such as init (initialisation first-weight of neurone), zmien_wagi (change of weight of neurone), zapisz_wagi (write weights all neurones), algorythm_WTA (algorithm WTA used to Euclidean distance), etc. Moreover implemented two functions for searching information in databases, one function for count of numbers printers, which must be to buy, etc. Also wrote two functions responsible for visualisations discoveries. Key words: self-organising neural network, searching discovery in databases

Model i implementacja systemowego algorytmu ewolucyjnego do poszukiwania nowego stanu systemu elektroenergetycznej sieci przesyłowej
pp. 59-67
Abstract: In article some results of using system evolving algorithm SAE for search a new state of development of electric power transmission network is presented. Electric power transmission network is simulated as a operator of transmission system (polish: Operator Systemu Przesyłowego: OSP). It is received by them existing distributed beginning population and existing fitness function which takes advantage of systems divergence. Identification of electric power transmission system (ESP) which is understudied as technology system and which is management by OSP is carried out using System Identification Toolbox. In result is obtained model of system in characteristic form such as th, tf, zpk, ss, ABCD. Next on the base model of OSP in transmission form is generated beginning population, which is using as chromosome population. After them SAE algorithm is generated new population, by them SAE is implemented in Matlab language. Results which is obtained in this process was interpreted using function from for example Control System Toolbox. Key words: genetic algorithms, system evolving algorithm SAE
