Relationship between Labor Productivity and Labor Quality
Assign a construction team to excavate earth, to erect formwork, to mix concrete, or to do other jobs; their working quality will decline if they intend to increase productivity, and an approximate linear relationship between labor productivity and labor quality is observed here. A more complex relationship function between labor productivity and labor quality is also considered in later case study:
where actual quality level of construction labor
working in activity
,
maximum quality level of construction labor
working in activity
; LPRD
minimum productivity level of construction labor
working in activity (i); LPRD
maximum productivity level of construction labor (i) working in activity
; LPRD
actual productivity level of construction labor
working in activity
.
