RDM - RELATIONSHIP DIAGRAMING METHOD

摘要

Recent Enterprise CPM developments focus upon activities and away from the relationships between activities that was the hallmark of the original ADM and PERT methodologies. This paper proposes a system to address these issues, designated as RDM or Relationship Diagramming Method. RDM documents the reason for a restraint between two activities. It expands the types of relationships, distinguishing partial performance, passage of time and a new "concurrent relationship." The RDM algorithm provides trend durations based upon actual performance to date and an automated assignment of optimistic and pessimistic durations for an integrated Monte Carlo analysis. ADM was developed in 1956 and PERT in 1958 based largely upon the limitations of computers of that era. PDM was developed using the more, but still limited power of computers in 1964. RDM provides for better planning and scheduling than traditional or current implementations of CPM using the computers of the 21st century.
