Metode Penjadwalan

Metode penjadwalan:

1. Diagram batang (Barchart).

2. Jaringan Kerja (Network planning), terdiri atas:

– Program Evaluation and Review Techniques (PERT)

– Metode Jalur Kritis (Critical Path Method - CPM)

– Precedence Diagramming Method (PDM)

Contoh Layout PDM - activity on node

(ES) Early start - the earliest the activity can start

(LS) Latest start - the latest the activity can start without delaying the project

(EF) Early finish - the earliest the activity can finish

(LF) Latest finish - the latest the activity can finish without delaying the project
