(a)
Summary Introduction
Interpretation: The network diagram of the given project is to be constructed.
Concept Introduction:
Project
(b)
Summary Introduction
Interpretation: The critical path activities of the network are to be determined.
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)
Summary Introduction
Interpretation: The project completion time is to be calculated.
