## Title

Implementation of Matrix Model Based Dispatching Algorithms on the Laboratory Model of FMS

## Abstract

The usage of matrix model based control algorithms will provide deadlock free behavior of controlled FMS. Such algorithms may include intelligent control techniques (fuzzy, neural or genetic) which can enhance a decision making process related to a sequencing of actions that must be taken in case of machine failure, wrong resource assignment etc. A microcontroller implementation of the matrix model based controller in the laboratory environment will show the possibility of industry applications of this novel automation technology.
