1. Consider the process shown below: Proin 2 Stor 2 Process 1 Pro 4 Stom1 Store 4 Process 3 Store 3 Each flow unit spends 10 minutes at process 1. It is then split into 2 parts: part 1 spends 15 minutes at process 2 and part 2 spends 12 minutes at process 3. At process 4, the two parts that were split after process one are reunited into a single unit. Depending on the type of flow unit, 20% of the flow units will spend 8 minutes at process 4, 30% will spend 12 minutes at process 4, and the remaining 50% will spend 9 minutes at process 4. A) What is the theoretical flow time of the process? B) If the actual wait times at the buffers are 6 minutes at store 1, 8 minutes at store 2, 14 minutes at store 3, and 5 minutes at store 4 (regardless of unit type), what is the flow time efficiency? C) Suppose the average unit has to pass through the first process 1 and 2 times (assume the wait time at store 1 is still 6 minutes). Recalculate both the theoretical flow time and the flow time efficiency D) Ignore the information in part C. Suppose that process I can process as many as 2 units at a time. Recalculate both the theoretical flow time and the flow time efficiency
