| Fundamental category | Main category | Subcategory (initial category) | Interpretation |
|
| Complexity of PC components | Structural complexity | Surface-to-volume ratio | The structural design is very complicated. The standardized production processes and manufacturing techniques may not be fully considered with detailed design |
| Number of openings, number of sections | Too many openings and cross-sections |
| Reinforcement ratio | Component reinforcement ratio reflects structural complexity |
| Number of embedded parts | Number of embedded parts in components |
| Production complexity | Material consumption | Large components require more embedded parts, rebar, and concrete |
| Mold assembly time | Time for manual assembly and removal of molds |
| Mold manufacturing accuracy | Mold precision check |
| Waiting time in production line | Waiting time for each procedure in the production line |
| Abnormal production status | Force Majeure factors such as equipment failures cause abnormal conditions in component production |
| Management complexity | Operating proficiency of workers | Experience and operational proficiency of workers |
| Mold turnover rate | Long turnover time and low mold reuse rates of molds |
| Stocking | Accumulation of finished components |
| Improper delivery time | Components leave factories ahead of or behind the schedule, disrupting the production cycle |
| Repair rate | Repairs or reproduction of finished components due to quality defects |
| Degree of automation of production line | Equipment utilization rate in production line |
| Information management level | Timeliness and accuracy of component production data transmission |
