Consider a process described by the following process flow diagram: task 1 (Adam) task 2 (Bob, machine 1) task 2 (Chloe, machine 2) task 3 (Dorothee, machine 3) task 4 (Dorothee machine 3) Note that it is the same machine (machine 3) used by the same person (Dorothee) to do tasks 3 and task 4. The task times are shown in the table below: Task Time (in minutes per unit) 4 5 1 N 5 2 3 3 3 4 3 (a) What is the capacity of this process? Express your answer in units per hour, round to two decimals if needed. 7 39 Assume that the process is empty at noon, and from noon to 3 pm one unit enters the process in every 5 minutes. At 2 pm, how many units will be waiting to be processed? Round your answer to two decimals if needed. If there will be no units waiting, enter zero. > 8 35 (c) As before, assume that the process is empty at noon, and from noon to 3 pm one unit enters the process in every 5 minutes. On average, how long does the flow unit arriving between noon to 3 pm will wait to be served? Express your answer in minutes, round to two decimals if needed
