Question

Lab 6 of 6: Critical Path Method;Critical Path Method;Critical Path Method (CPM) is technique used to identify the possible ways something might be scheduled and determine which method or path would take the most time. The path with the longest time is defined at the "critical path." This methodology was development by J.E. Kelly of Remington Rand and M. R. Walker of DuPont as means of scheduling the construction of duPont's chemical facilities (Heizer & Render, 2006, p. 61).;The use and construction of CPM diagram is accomplished in six steps (Heizer & Render, 2006, p. 61);1. Define the project and breakdown its structure.;2. Determine the order each activity must occur.;3. Connect all activities via a network diagram.;4. Note time information on the diagram.;5. Calculate the length of the different paths.;6. Use the finish diagram schedule your activity.;The construction of a CPM diagram is fairly straightforward. The following is an example of the steps to take to complete on.;First it is important to note when constructing a CPM diagram you will typically have discover all the information provide in the following table yourself.;Activity;Title;Immediate Predecessors;Time (weeks);1-2;A;-;4;2-3;B;A;2;3-4;D;B;4;3-5;C;B;2;4-5;E;D;5;5-6;G;C, E;2;4-6;F;D;3;6-7;H;G, F;3;1. We begin the first activity with 1 and end it with 2. This 1-2 activity in this example is called "A" and has a length of 4 weeks.;2. The next activity (2-3), is called "B". I immediately follows "A" and runs or 2 weeks.;3. Activities "C" & "D" are both preceded by activity "B" and activity "E" is preceded by "D".;4. Activity "E" is preceded by "D" and activity G is preceded by both "C" & "E" activities.;5. "F" is preceded by "D" and "H" is preceded by "G" & "F".;6. We now describe all the paths we can take to complete this task using activity letters and then substitute the corresponding time for each activity and total the time it will take to complete each path.;Path #1: A + B + C + G + H = 4 + 2 + 2 + 2 + 3 = 13 weeks;Path #2: A + B + D + E + G + H = 4 + 2 + 4 + 5 + 2 + 3 = 20 weeks;Path #3: A + B + D + F + H = 4 + 2 + 4 + 3 + 3 = 16 weeks;We can now see that Path #2 (A,B,D,E,G, H) is the critical path.;References;Heizer, J. & Render, B., (2006).Operations management (8th ed.).

Then, construct a CPM chart using the following data and note which path is the critical path.;Activity Title ImmediatePredecessors Time (weeks);1-2;A;n/a;1;2-3;B;A;5;2-4;C;A;2;3-5;D;B;2;3-7;E;B;2;4-5;F;C;2;4-8;G;C;3;5-6;H;D, F;2;6-7;I;H;3;7-8;J;E, I;3;8-9;K;G, J;2;Deliverables;Using the table above, construct a CPM diagram. Identify all possible paths, calculate the time to complete each of them, and identify which path is the critical path.
