Using the expert systems in the operational management of production

In the conditions of computing the human society, the operational management activities can be improved by using artificial intelligence. The expert system is an intelligent system based on the symbolic representation of knowing, implemented on 2 hardware structure specific to the application, which processes a lot of knowledge for solving special issues about activities that are difficult to examine.
