125 points) Consider a process that consists of three activities Activity 1 has a processing time of 150 minutes and has two workers assigned to it. Activity 2 follows actity 1 and has a processing time of 90 minutes with one worker assigned to it. Finally, Activity 3 follows activity 2 and has a processing time of 120 minutes with one worker assigned to it a) U9 points) What is the hourly capacity of the activities? Which activity is the bottleneck? What is the hourly capacity of the process? b) 8 points) Suppose we have one more worker that can perform any activity which activity should this worker perform? Which activity is the bottleneck now? What is the hourly capacity of the process with this additional worker a 18 points) Consider the orginal question with a total of four workers and suppose that we could move 30 minutes of work from any one of the activities to another. How should we reallocate these 30 minutes? Which activity is the bottleneck now? What is the hourly capacity of the process now
