ABSTRACT
Most construction projects involve a combination of repetitive and
non-repetitive tasks. A typical example is highway construction in
which tasks such as clearing and grubbing are performed repeatedly
over the length of the highway, and tasks such as site office
construction are carried out only once. Presently, traditional network
scheduling methods such as CPM and PERT are used for the
scheduling and monitoring of such projects. Despite their extensive
use these methods have a number of shortcomings:
• Network methods do not guarantee continuity of work in time
which may result in crews being idle.
