The jobs necessary to build an experimental model such as research, design, engineering drawings, production, etc. are labelled as A through G. Table 1 shows the data required for this problem. The job can start at the same week when its immediate predecessor(s) is (are) 4 completed. Answer the following questions, Q1 & Q2. 5 6 Q1: Draw the AON graph for this project.
