Q2: For the activities shown in the table below, it is required to reduce the total duration of the
project four days by using crash program and network diagram, If you knew that indirect costs is
150 S/day and the delay fine is 100 S/day after the 14th day. Find new cost after crashing the
project four days?

- Q1: By using the PERT technique, the durations of the activities were calculated as shown in the table below, Draw an activity network for project by using Activity On Node (AON) method and find: 1. The project's total duration and date of completion and CP (assume the project start date is the 1st of June 2025)? 2. The overall variance of the project? 3. The probability of completing the project in 30 days? 4. The probability of completing the project in 22th of June 2025? 5. With a probability of 75%, what is the expected duration and date for completing the project?
