Efficiency analysis of information criteria application in spare parts demand forecasting
The paper presents a new approach to the spare parts forecasting issue – a method which combines regression modeling, information criteria and artificial neural networks ANN. The research presented in this article compares efficiency of classical methods with the artificial intelligence tool in the scope of spare parts forecasting. Artificial Neural Networks have been advocated as an alternative to traditional statistical forecasting methods. Classical methods, such as exponential smoothing or mean average, have been used for several decades in forecasting demand. However, many of these techniques may perform poorly when demand for an item is lumpy or intermittent. In the paper three concepts of using ANN in spare parts forecasting – micro, macro and hybrid – were described. The article presents also the variable selection issue, which is of a great importance in any model building.

Optimization of process of stocks controling based on group ordering the goods
In the article it is proposed an innovative aspect for the process of stocks controlling. It is presented an opportunity using of nonlinear programming for the optimization of process of the group ordering the goods, which is the ‘coverage analysis’. The attention is paid for the formation of scale effect and the occurrence of trade-off relation, connected to safety of the customer needs by the minimization the general costs of maintenance the stocks.
