Operations Research: Project Orchestration Consider a project with activities A, B, C, D, E, F, G, H, I and J. The following table shows the precedence and duration (in days) of each of the activities. Precedence Activities A B D duration (in days) 8 10 E 15 5 7 10 3 B.C A, B, C E D, E C G F H, F G . 1 8 4 4 J a) Draw the project network. b) Indicate the duration of the project. What is the critical path? (Justify) c) Activity D is performed abroad and has experienced a delay of 6 days. What are the consequences for the project closure? d) Later, activity I suffered a delay of 3 days, because its execution is carried out with a machine that does not came in time. It must cumulatively consider the two delays (from machine I and from machine D of the previous question). What are the consequences for the completion of the project
