During some off-peak hours, orders arrive at the rate of 3 orders/hour. Suppose that there are only 2 in-store shoppers. Assume the same time estimates and number of shoppers as in the previous question. That is, it takes 25 minutes for a shopper to pick all items on the list, and 15 minutes to check out the items and move them to the staging area.

For simplicity, we may consider all time durations (including the operational times mentioned above and the interarrival times of orders) are deterministic (i.e., they are constants without any variability).

Develop a Gantt chart to visualize the process. Please include at least 4 orders in the Gantt chart.

Note: 1 - In your Gantt chart, you may combine "pick items on the shopping list" and "Check out items and move them to the staging area" into one activity, since they are performed by the same person.

2 - You may click on "Add File" to upload an image of the chart. You may also provide a brief explanation, if preferred.
