Introduction

Thechemicalfiberindustryisacriticalsectorinthemanufacturingindustryandplaysavitalroleintheglobaleconomicdevelopment.Oneoftheessentialprocessesinthechemicalfiberindustryisthewindingoffiberproductsontospoolsusingatake-upmachine.Atypicaltake-upmachineisasingle-trackdual-take-upmachinethatcanwindtwospoolssimultaneously.Theoperationofthemachinerequiresfrequentspoolchangesandadjustments,leadingtosignificantdowntimeandreducedproductionefficiency.

Toimprovetheproductionefficiencyofthesingle-trackdual-take-upmachine,weproposeaschedulingdesignthatoptimizestheproductionscheduleandminimizesdowntime.Ourschedulingmethodconsidersmultiplefactorssuchasmachineavailability,orderprioritization,andprocessingtime.Theprimarygoalistomaximizethemachine'sutilizationrateandreducedowntimewhilemaintainingtherequiredproductioncapacity.

SchedulingDesign

Theproposedschedulingdesignconsistsofthreemaincomponents:orderprioritization,schedulingalgorithm,andsimulationmodel.

OrderPrioritization

Theorderprioritizationmoduledeterminesthepriorityofeachorderbasedontheexpecteddeliverydate,ordersize,andcustomer

importance.Theprioritizationalgorithmensuresthathigh-priorityordersarecompletedfirst,whichhelpsmeetcustomerdemandsandincreasecustomersatisfaction.

SchedulingAlgorithm
