A construction project is modeled by the activity network given below. The activities are represented by the arcs and the numbers in brackets on each arc represents the time (in days) to complete the activity. Each activity requires one worker. The project is to be completed in the shortest time.I. Using the network provided, calculate the earliest time and latest time for each activity. [8]II. State the critical activities and identify the critical path(s). [3]III. Find the total float of activities D and F. You must show your working. [3]IV. Explain why it is important for a project manager to use float in project management? [3]

with detailed answers #### a) Define activity scheduling.b) List the attributes of the project.c) What are the types of Network diagram?d) What is cost estimation?e) What is staffing in project management?

Which of the following represent individual tasks or activities in the project.a.Slackb.Nodesc.Critical Pathd.Duration

What is the significance of a critical path?Question 15Answera.The critical path reveals the shortest and longest paths and their differenceb.The critical path shows the number of available float in the projectc.Activities in the critical path are critical activities for achieving project objectivesd.The activities in the critical path have the highest number of float, showing the amount of time those activities can be delayede.When an activity in the critical path is delayed, the entire project will be delayed

Write an activity that can apply to minimize the critical path of a proj ect

When identifying and calculating the critical path, which is the most important item to identify?Multiple Choicethe sequence of tasks that take the most worker effort to completethe sequence of tasks that take the shortest time to completethe sequence of tasks that take the longest time to completethe tasks that cost the most money to completethe sequence of tasks that require the most resources and materials
