Compared　with　other　production　methods,　multi-variety,　small-batch　production　driven　by　order　become　a　lot　more　sensitive　to　the　disturbances　of　workshop　environment,　orders,　and　processing　equipment.　This　makes　a　great　impact　on　workshop　scheduling.　Aiming　at　this　problem,　this　paper　designs　a　real-time　workshop　digital　twin　scheduling　platform　for　discrete　manufacturing.　It　improves　the　flexibility　of　the　intelligent　workshop　and　the　response　processing　speed　after　dynamic　disturbance.　The　platform　can　real-time　monitor　of　the　physical　workshop　and　track　orders,　products,　equipment　and　other　information.　Further,　the　platform　and　visualization　technology　were　explored　to　work　together.　Then,　the　true　display　of　changes　after　production　line　decision　was　displayed.　It　enables　managers　to　carry　out　production　scheduling　verification　in　the　virtual　workshop,　which　reduces　the　repeated　changes　of　physical　workshop　production　scheduling.　Finally,　the　platform　was　verified　in　a　discrete　manufacturing　workshop.　The　scheduling　platform　based　on　digital　twins　helps　manager　to　immersivity　develop　factory　production　strategies.　The　production　efficiency　was　then　enhanced.　The　platform　can　ensure　the　effective　operation　of　the　manufacturing　system.　©　Published　under　licence　by　IOP　Publishing　Ltd.
