A team task complexity measure for emergency procedures in fully automatic metro

摘要

A measure of team task complexity for emergency procedures in fully automatic metro is proposedusing a Euclidean norm based on two factors: internal complexity of network nodesNode_(com − inside) and external complexity of network nodes Node_(com − outside). The development of theoperation complexity measure followed four steps. First, team task complexity network for emergencyprocedures was constructed. Second, the task complexity (TC) method used as complexitymeasure of individual was adopted to measure the internal complexity of network nodes. Then,the external complexity of network nodes was measured by structure entropy. Finally, the teamtask complexity values for emergency procedureswere determined by the Euclidean norm of thetwo factors. To verify the validity of this team task complexity measure, a one-factor experimentwas designed to test the proposed model. Thirteen team subjects participated in the experimentand performed 5 typical emergency scenes. Both objective indexes (TeamTIME) and subjectiveindexes (TeamWORKLOAD and TeamSUBCOMPLEXITY)were used in the experiment. The data analysisshowed that the TeamTIME, TeamWORKLOAD, and TeamSUBCOMPLEXITY could be predictedwell from the team task complexity value. The proposed team task complexity measure can beused for evaluation of emergency procedures design in fully automatic metro.
