ABSTRACT
Critical path network analysis is a term that covers a number of project planning methods that originated around 1950. Most planning and work scheduling systems used in manufacturing plants and materials control are really network analysis methods. At first sight this arrow diagram suddenly looks very complicated when compared with the three earlier examples in this chapter, but it is only a multiple combination of the notational elements already described. We used Micro Planner X-Pert to process the network analysis data for the 4J airstrip project. Printed reports from project management software often require large areas of paper, so neither the network analysis plot nor the useful Gantt chart produced by Micro Planner X-Pert, but both were well plotted and easy to follow by scrolling them on the computer screen. It describes a fictional project to build a private airstrip on farmland and they showed how it might have been planned using an activity-on-arrow critical path diagram.
