IDENTIFICATION OF CONSTRAINTS IN CONSTRUCTION …

Removing constraints (Goldratt 1990, Chua et al., 2003) from bottleneck(s) are the most effective means of improving overall system performance. Once the existing constraints are removed, however, new ones emerge. Identifying and removing constraints represents an iterative procedure that pushes system capacity closer and closer to its limit.
