**7. RCM - maintenance management integrated software**

Based on the algorithm for calculating and optimizing PM, presented in the previous sections, we propose an integrated model of software for the implementation and exploitation of the RCM. This model is specifically designed for OEL belonging to EDS.

To achieve the proposed information system we used the Matlab environment, because it offers the possibility to write and add programmes to the original files, allowing the development of the application characteristic to the EDS domain. The choice of Matlab was decisively influenced by the facilities offered by this environment in terms of achieving interactive user interfaces in the form of windows and menus, with the toolbox GUI (Graphical User Interface) and statistical processing with the Statistics Toolbox (Dulau et al., 2007), (Dulau et al., 2010).

For interactive control of various representations, we do the following steps:
