This work focuses on the problem of inventory management which is an important element of the supply-chain management challenge. The goal of our research was to develop an application which supports decision making regarding optimal strategies for producing electrical machines. The multi-agent approach offers several valuable features which may be exploited for supply-chains management: problem decentralization, isolation of different kinds of sub–problems and solving them separately, as well as modeling and predicting the behavior of the particular modules and referring to the means offered by distributed intelligence.
