1. The table below indicates the task times for a line flow process, where the work starts with Task A and ends with Task D. The current process has a single worker assigned to each station; each worker performs one of the tasks. The manager is considering two alternatives that retain the use of the current four workers but reallocates their work assignments. The first alternative involves training and equipping each of the four workers to perform all of the tasks at four parallel, fully equipped workstations where a worker performs all tasks for a particular output. The second alternative involves training and equipping two of the workers to perform Task A at two parallel workstations, and training and equipping the remaining two workers to perform the combined work of Tasks B, C, and D at two parallel workstations.

Task A	240 seconds
Task B	40 seconds
Task C	50 seconds
Task D	70 seconds

1. What is the throughput time for the first unit (assume empty system) for the current process, the first alternative, and the second alternative?
2. What is the cycle time for the current process, the first alternative, and the second alternative?
3. What is the output rate (per hour) for the current process, the first alternative, and the second alternative?
4. In the current process, what is the utilization for each task?
5. In the first alternative, what is the utilization for each process?
