1. In the process below, as shown, 75% of the arrival rate goes through step 2 and 4, and the rest of them go through step 3. Determine the value of T. (Duration or average Flow Time of step 1), 12 (Average Inventory for Step 2), and T. (Average Flow Time of step 3). Do not forget to convert the units if needed for dimensions to match, before using a parameter value in the formula (6 points). Consider each month to be 30 days if needed. Step 4 H-120 75% Step 2 T2-2 days 1-1,000 applications per month Start Step 1 11-200 End 13-100 2. Identify the critical path in problem 1, and show your calculations through which you concluded on the chosen path (4 points) 3. Explain the concept of "Production Mix Modification strategy by using the following data, which show the time required to process 2 tasks at a manufacturing shop. Provide conclusions on what sequence of production is the best. (4 points) Task 1: Flow time=3minutes Task 2: Flow time = 6 minutes
