Mo Ri-xiang, Liu Fu-chun. Correctability and Algorithm of DiscreteEvent System Based on State Tree[J]. 2015, 32(2): 53-57.DOI: 10.3969/j.issn.1007-7162.2015.02.010.
Failure diagnosability and correctability of discreteevent systems are widely studied. This paper mainly focus on the question about correcting failure events of discreteevent systems (DESs) under the condition that failure events are diagnosable but uncontrollable
for making the system run within accepted states. With the formalization of correctable states
A correcting model based on state tree is proposed. Meanwhile
the necessity of correctable states is derived and an algorithm for checking correctable states is proposed.
