(a)
Expert Solution
Explanation of Solution
A.
Given Information:
There are 5 regular lines ad 1 express lines.
Average time a customer spends in a regular line = 11 min which means that one regular line can handle 5.45 customers per day.
Average time a customer spends in an express line = 4 min which means that one express line can handle 15 customers per day.
Shift duration = 12 hours per day
Thus,
The capacity of 5 regular lines =
The capacity of 1 express lines =
Therefore, the maximum capacity of store = (327 + 180) = 507 customers per day.

Explanation of Solution
Given Information:
There are 5 regular lines ad 1 express lines.
Average time a customer spends in a regular line = 11 min which means that one regular line can handle 5.45 customers per day.
Average time a customer spends in an express line = 4 min which means that one express line can handle 15 customers per day.
Shift duration = 12 hours per day
The store’s capacity by day of the week is as follows:
| Period | Monday | ||
| Hours | No. of lines open | Capacity (customers per day) | |
| 9-12 noon | 3 | 1 | |
| 12-4 PM | 4 | 2 | |
| 4-6 PM | 2 | 3 | |
| 6-9 PM | 3 | 4 | |
| Total Capacity of Regular Line (Customers per day) | 158.05 | ||
Since the express line is always open, and the capacity is 180 customers per day.
Therefore, the maximum capacity on Monday is 338 customers per day.
Also, the maximum capacity on Tuesday, Wednesday and Thursday will be 338 customers per day as same number of regular lines are open as on Monday.
| Period | Friday | ||
| Hours | No. of lines open | Capacity (customers per day) | |
| 9-12 noon | 3 | 3 | |
| 12-4 PM | 4 | 3 | |
| 4-6 PM | 2 | 5 | |
| 6-9 PM | 3 | 5 | |
| Total Capacity of Regular Line (Customers per day) | 250.7 | ||
Since the express line is always open, and the capacity is 180 customers per day.
Therefore, the maximum capacity on Friday is 431 customers per day.
| Period | Saturday | ||
| Hours | No. of lines open | Capacity (customers per day) | |
| 9-12 noon | 3 | 5 | |
| 12-4 PM | 4 | 5 | |
| 4-6 PM | 2 | 3 | |
| 6-9 PM | 3 | 3 | |
| Total Capacity of Regular Line (Customers per day) | 272.5 | ||
Since the express line is always open, and the capacity is 180 customers per day.
Therefore, the maximum capacity on Saturday is 452.5 customers per day.
| Period | Sunday | ||
| Hours | No. of lines open | Capacity (customers per day) | |
| 9-12 noon | 3 | 2 | |
| 12-4 PM | 4 | 4 | |
| 4-6 PM | 2 | 2 | |
| 6-9 PM | 3 | 1 | |
| Total Capacity of Regular Line (Customers per day) | 158.05 | ||
Since the express line is always open, and the capacity is 180 customers per day.
Therefore, the maximum capacity on Sunday is 338.5 customers per day.

- Draw a sequence diagram on this scenario. Consider an e commerce website, the customer will search for the items either by category, by price, by color or by size. the customer will add the selected items to the shopping cart. He/she can either continue shopping or can perform checkout. On checkout bill/invoice will be generated and the customer will enter personal information including email, phone and address; will choose cash on delivery option or card payment. If card payment selected, he/she will enter the card information. The bank object will validate the card, if validated the required amount will be deducted and the item will be dispatched to the provided address in both cases (COD/ valid card payment).arrow_forwardThe Swanky Hotel provides room service for its guests.

- PS.55 Four Corners is an IBC company that sells delicious Navajo tacos in the Crossroads Food Court. Part of their success can be attributed to the freshly fried Indian bread that is used not only for the tacos, but also for dessert items. As demand grows the fry-bread process is becoming a bottleneck. Operations management for the company is looking at two different process options to replace the highly manual process currently being used. Option 1 (medium automation) would cost $190 to implement whereas Option 2 (high automation) would cost $450. With Option 1 the variable cost per fry bread produced would be $0.23. The variable cost for Option 2 would be $0.11 per fry bread. At what volume (demand) of fry breads is the cost for the two options the same? (Display your answer to two decimal places.) What is the total cost for either option at this break-even volume (answered in the last question)? (Display your answer to two decimal places.)arrow_forwardA fast-food restaurant has a drive-thru window and during peak lunch times can handle a maximum of 60 cars per hour with one person taking orders, assembling them, and acting as cashier. The average sale per order is $9.50. A proposal has been made to add two workers and divide the tasks among the three. One will take orders, the second will assemble them, and the third will act as a cashier. With this system, it is estimated that 85 cars per hour can be serviced.arrow_forwardA manager must decide how many machines of a certain type to purchase.

Variable costs will be $20 per customer, andrevenue will be $45 per customer.a. Determine the break-even point for each rangearrow_forward
- A local restaurant is concerned about their ability to provide quality service as they continue to grow and attract more customers. They have collected data from Friday and Saturday nights, their busiest time of the week. During these time periods, about 75 customers arrive per hour for service. Given the number of tables and chairs, and the typical time it takes to serve a customer, they figure they can serve, on average, about 100 customers per hour. The owners now anticipate that in one year, their demand will double from the current demand of 75 arrivals per hour, as long as they can provide good service to their customers. How much will they have to increase their service capacity to stay out of the critical zone? That is, how many customers should they be able to plan for? Keep in mind that service capacity utilization rate = arrivals rate / service rate.arrow_forwardOwners of a local restaurant are concerned about their ability to provide quality service as they continue to grow and attract more customers.
