Problem 1 Answers: a) Draw a network diagram for the project. See diagram on second page (go to view network diagram) b) Mark the critical path and state its length. The critical path is in red color (go to view tracking Gantt). The length of the critical path is 18 days of duration. c) If the Maser has to be completed 2 days earlier‚ would it help to: i. Buy preassembled transmissions and drive trains? Yes‚ however is dependent of supplier inventory

shows that there are two critical paths for the current process‚ which is 20 weeks long and includes the following critical activities: obtain funding approval (A)‚ finalize engineering (B)‚ build dies/tools (D)‚ raw material delivery (K)‚ initial production run (L)‚ ship product (M)‚ train workers (F)‚ and de-bug process (G). See figure below. Gadget’s first option is to reduce the amount of product advertising. Although this might reduce cost‚ advertising (J) is not a critical activity and won’t reduce

Duration and Critical Path By addition‚ the number of the days which are needed for every activity on critical path can be determined as project duration. For Vobien Ltd ‚ the project duration is 50 days. Critical path are those node which have zero float and cannot be delay or early in their activity of time. According to Field and Keller (1998)‚”Critical Path is normally easily spotted as they pass through nodes with same earliest and latest time.” For Vobien Ltd‚ the critical path is A B

Cost Estimates to each activity 5. Compute the longest time path through the network – this is called the Critical Path 6. Use the network to help Plan‚ Schedule‚ Monitor‚ and Control the project Perform a Critical Path Analysis: The Critical Path is the Longest Path Through the Network The Critical Path is the Shortest Time in which the Project Can Be Completed. Any delay in Critical Path activities delays the project. Critical Path Activities have no slack time Variability in Activity Times:

PERT is a widely used method for planning and coordinating large-scale projects. To obtain: • A graphical display of project activities. • An estimate of how long the project will take. • An indication of which activities are the most critical to timely project completion. • An indication of how long any activity can be delayed without delaying the project.

1. Provide the definitions of critical path and critical chain. How do they differ? Critical path and critical chain are both schedule network analysis techniques. Critical path is the one that determines the shortest time to complete a project‚ which assumes low uncertainty and does not consider resource dependencies. Critical chain is a modified or refined technique about critical path; it involves the deterministic and probabilistic approaches to analyze the project schedule‚ which is

INTRODUCTION Critical path is made up of a series of tasks that must be completed by a schedule date and/or time. Any task on the critical path that will affect whether the project finish date is delayed is called a critical task. You can view the critical path using any Gantt Chart (McDonough‚ 2012) view. Knowing when a task is slipping or late or when a project ’s end date must be adjusted enables managers to make important decisions for their team. A couple of advantage to using Critical Path Method
