As the core operation of internal-combustion locomotives' mid-reparation,the disassembly and assembly operations are significant to locomotive performance resumption and railway safety.As enormous in scale,it's often managed by experience in practice,which restricts the improvement of operational efficiency and quality.Through work element decomposition,analysis on precedence constraints and time study,we use AOA flow net to model the complicated operation mathematically.The model is in line with the requirements of importance,defect,complexity and coherence.Base on the model,the critical path method is used to carry out quantitative researches.Through exploring the connotation of the concept and analyzing the characteristics of the data,two evaluation methods for scoring the work-teams' workload intensity:the average time flexibility index and the route sequencing are proposed and applied,upon which an optimization scheme on operational flow is established.
