Concept Introduction:
Project
(b)
Summary Introduction
Interpretation: the critical path of the network is to be identified.
Concept Introduction:
Project Scheduling is used in Project planning and coordination by using Program Evaluation Review Technique (PERT) and Critical Path Method (CPM). PERT is a network based scheduling procedure. This technique is used to plan, schedule and control different project such as construction works, design installation of system, maintenance work and research and development process.
(c)
