Problem 1: For the network given below, (a) Draw the bar chart, resource histogram, and cumulative resource distribution for the early schedule. Make comments about potential problems concerning resource utilization in this project. (b) Following your intuition, what can be done to improve the resource utilization? Do not delay the finish date of the project. Support your solution. (c) Assuming that the resource availability is limited not to exceed 8 units at any time of the project, what has to be done to maintain this condition? The project can be delayed only if necessary. Support your solution
