PENJADWALAN PROYEK DENGAN PRECEDENCE DIAGRAM METHOD (PDM) DAN RANKED POSITION WEIGHT METHOD (RPWM)

Abstract

In project construction world, many models of project planning have
been intensively used, such as a Precedence Diagram Method (PDM). Scheduling
on PDM considers dependency between activity and duration of each activity. To
deal with the limited resources, hence allocation and resources levelling need to be
implemented using Resource Scheduling Method. Activity scheduling priority is
based on activities with the minimum floating time. If some activities have the
same floating time, a problem arises in determining the priority of scheduling
activity. In the Ranked Position Weight Method (RPWM), allocation and resources
levelling are based on positional weight of each activity. Positional weight is
determined by adding the sum of duration of an activity with the sum of a total
duration of all following activities. The value of positional weight of an activity
shows a degree of its importance in relation to other activities. The effects of the
construction work condition on the project activity should be considered when
preparing precedence logic (relationship of interdependency activities).
