Study on Complexity of Precast Concrete Components and Its Influence on Production Efficiency

Table 4

Additional revisions to some indices.

Revision	Reason
Delete “number of sections”	The increase in the number of openings will increase the number of sections. The indices are repeated, and the number of openings is easier to measure.
Delete “stocking”	Stocking is for the entire factory, and an individual component cannot be measured in this dimension.
Add “amount of exposed rebar”	The amount of exposed rebar can reflect the structural complexity, which is related to the stability and bearing capacity of PC components and will also affect design and assembly of molds.
“Improper delivery time” is revised to “delivery delay”	In current practice, there are almost no cases where components are shipped in advance. In other words, the index is meaningless.
