project. It is basically a method to analyze the tasks involved in completing a given project‚ especially the time needed to complete each task‚ and to identify the minimum time needed to complete the total project. PERT planning involves the following steps: Identify the specific activities and milestones. Determine the proper sequence of the activities. Construct a network diagram. Estimate the time required for each activity. Determine the critical path. Update the PERT chart as

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:

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.

What is the level of risk in completing tasks on the critical path(s)? Explain. The critical path is added to the appendix of this case report. As shown in Figure 1 and 2‚ many tasks are correlated so that one critical phase can affect the other. Here‚ we divided the entire process into three parts: namely by “Detailed Design” part (on the left

12 Mar 13 MRP Notes What is MRP Material Requirements Planning (MRP) is a software-based (production) planning and inventory control system used to manage manufacturing processes. MRP is a technique that uses the bill of material‚ inventory data and a master schedule to calculate requirements for material. MRP time phases material requirements based on setbacks defined by a combination of the bill of material structure and assembly lead times. The result of an MRP plan is a material
