Increasing of the Efficiency of Flexible Manufacturing System

Management of universal shelf stacker process many varied operations, whose are different in difficulty of solved problems, time of reaction of controller and next parameters. Usually is used one controller with all functions, which have many external input-output modules and have to solve parallel many tasks together. The control application have to be very complicated and blind with risk of collisions control processes and needed of solving control process priority. If the processes are separated to the groups, every group of processes solved with separate control automat. For simple processes, whose needs immediate reaction can be used simple and easy controller, complex control processes have to been solved with controller with sufficient performance, mathematical performance and adequate memory.
