This　work　studies　the　deadlock　and　blockage　control　problem　of　an　automated　manufacturing　system　(AMS)　with　a　single　unreliable　resource.　It　aims　to　develop　a　robust　control　policy　to　ensure　that　AMS　can　produce　all　parts　in　the　absence　of　resource　failures,　and　when　the　unreliable　resource　fails,　the　system　can　continuously　produce　all　parts　that　do　not　require　the　failed　resource.　To　this　end,　we　divide　the　system　into　two　regions,　continuous　and　non-continuous,　based　on　whether　all　parts　in　them　can　be　produced　continuously　or　not.　For　the　non-continuous　region,　dominating　region　constraints　are　established　to　ensure　that　all　parts　in　it　do　not　block　the　production　of　parts　in　the　continuous　region,　and　an　optimal　deadlock　avoidance　policy　based　on　a　Petri　net　model　is　introduced　to　guarantee　its　deadlock-free　operation.　For　the　continuous　region,　we　configure　a　resource　order　policy　to　ensure　the　smooth　productions　of　AMS.　By　integrating　the　dominating　region　constraints　and　deadlock　avoidance　policy　with　the　configured　resource　order　policy,　we　propose　a　novel　robust　control　policy.　It　is　proven　to　be　of　polynomial　complexity　and　more　permissive　than　the　existing　one　with　the　same　resource　order　policy.　Also,　it　is　tested　to　be　more　permissive　than　other　existing　policies.　©　2018　Chinese　Automatic　Control　Society　and　John　Wiley　&　Sons　Australia,　Ltd
