Cost-loaded production model for planning and control
Abstract: This paper describes a cost-loaded production model that supports
integrated project planning, scheduling and estimating and real-time cost
and schedule control. The production model integrates product, process, and
resource information between all levels of detail and within each level of
detail of construction management information. It describes and calculates
project schedules and cost estimates explicitly at any level of detail desired
by project participants. A hierarchical construction planning, scheduling,
and estimating process and corresponding software prototypes assist the
user in generating and updating the cost-loaded production model. The main
contributions of this work are the consistent representation of component,
action, resource, and sequence constraint objects at all levels of detail and
the formal planning, scheduling, and estimating processes and mechanisms.
These are the two essential components that make the cost-loaded
production model possible. The production model enables construction
managers to work from general project information to detailed project
information, generate detailed what-if scenarios rapidly and control and
manage a project's progress on a frequent and precise basis.
