In order to facilitate the maintenance support resource demand analysis and improve efficiency of analysis, computer aided maintenance support information platform is proposed. It analyzed overall platform design and the main sub-module features design in detail, with a certain type mobile howitzers as an example to show the partial function of platform and has been successfully applied to the part of the ordnance equipment maintenance and support resource development. The results show that the platform in the realization of the maintenance support resource demand analysis as well as can publish maintenance support technical material needed, improve efficiency and accuracy of analysis, shorten the technical material development, reduce repeated analysis and the development costs.
