Solve for the cost slope of each activity. 3.2. Draw the all-normal time network, determine total cost, enumerate the paths, find the critical path and completion time. 3.3. Draw the all-crash time network, determine total cost, enumerate the paths, find the critical path and completion time. 3.4. Finish the project in the shortest time with the lowest cost. Tip: Expand the non- critical activities in an all-crash time network. 3.5. Finish the project in 40 weeks. Compress some of the critical activities in an all- normal time network
