The TIA A3 system has been developed modularly and can be extended at any time. The modules Trend Calculation and the Rolling Monthly Planning form the core system. Other modules, such as the Decentralized Sales Planning module, can be supplemented as required and are fully integrated in the total solution. A3 offers special solutions for special industries. TIA offers solutions for the textile, shoe and the clothing industry with the modules AVACOS, Extrapolation Forecast and Size Splitting.

The individual modules receive the necessary data over interfaces from the appropriate merchandise information systems and supply the results to attached PPC- systems. Thus an integration into existing system environments is ensured.

The data are stored in a Oracle database and are therefore up-to-date and at the user`s disposal. A history of 36 months serves for the creation of the prognosis, which is computed for 24 months into the future per article, products category and distribution channels.
