Generation of restart states for manufacturing cell controllers
Journal article, 2011

A method for restart of manufacturing systems has recently been introduced. After correction of a fault. the system resumes normal production by returning to a certain restart state in the control function. and from there reexecuting parts of the work schedule. The current paper concerns automatic generation of the restart states, using discrete event systems theory. The generation process finds all possible restart states that guarantee that the execution restrictions are fulfilled during a restart, and that the production goals can be maintained. The number of restart states is minimized to reduce the number of necessary extensions to the control program. (C) 2011 Elsevier Ltd. All rights reserved.
