Abstract: ThetasksplanningmethodofTDRSinapplicationondemandmodelwasstudied.Thecommondescriptivecharacteristicsoftaskweresummarizedanddividedintobasicandadditionalcharacteristics.Theplanningprocessandthestatechangeprocessoftaskinasynchronousresourceavailperiodwasanalyzed.Theclassificationmethodoftasktypeandtheconstructedmethodoftasksetswasproposed.Themainconstraintconditionsoftaskplanningweregiven,andtheoptimalobjectsfromapplicantandmanagerswereproposed.Ataskplanningalgorithmwasdesignedbasedontheriskaversionrule,aftertheconflictdetectionmodelandopportunityevaluationmodelwereconstructed.
