The Swanky Hotel provides room service for its guests. The process for room service begins with a room service manager who takes orders by phone at an average of 5 minutes per order. The manager then sends the order to the kitchen, where it takes an average of 16 minutes to prepare the food for each order. There are four chefs in the kitchen. If the customer requires a beverage (alcoholic or nonalcoholic), the room service manager sends the order to the bar at the same time the order is sent to the kitchen. It takes 3 minutes to fill the order by one bartender, and 80 percent of the orders require a beverage. When the kitchen and bar orders are both ready, a waiter will take them to the room and bill the guest. There are six waiters to provide the service, and each order takes 20 minutes for the waiter to complete. Assume that on Friday evenings an average of 10 room-service orders per hour are placed. How many orders are in the system on average on Friday nights?

A local bakery is renowned for its elaborately cecorated sheet cakes. Consider the following process information: One baker is ivailable to prepare the cake batter (measuring and mixing ingredients and then adding it to baking pans). On average, this takes 10 minutes to prepare two cakes, ie. to make enough batter for 2 cakes and to add the batter to 2 cake pans. Move time to add and remove them from the oven is neglig bile, it takes 32 minutes to bake cakes - the bakery has two ovens, each able to hold 2 cakes. The one pastry chef on staff puts on an amazing show that draws a crowd all day-each cake is decorated in 6 minutes. The bakery operates 8 hours per day. Answer each of the following questions: a. What is the cycle time (in minutes per cake) of each stage - preparing, baking, and decorating? b. What is the dally process capacity? Explain. c. If orders arrive at a rate of 3 cakes every 20 minutes, can the bakery meet the caily demand Explain, Note: Be clear about how you…
An automated car wash serves customers with the following serial process: pre-treat,wash, rinse, wax, hand dry. Each of these steps is performed by a dedicated machineexcept for the hand-dry step, which is performed manually on each car by one of threeworkers. The steps of the process have the following processing times:• Pre-treat: 1 minute per car• Wash: 5 minutes per car• Rinse: 2 minutes per car• Wax: 3 minutes per car• Hand dry: 8 minutes per cara. If the car wash has a demand of 15 cars per hour, what is the flow rate of the process?b. If the car wash has a demand of 15 cars per hour, what is the utilization of the machinethat performs the wax process?
The Tesla Model S, one of the most sought-after luxury cars, is produced in Tesla’s Freemont factory in California. The production process can be broken up into the following subprocesses. Stamping: In the stamping process, coils of aluminum are unwound, cut into level pieces of sheet metal, and then inserted into stamping presses that shape the metal according to the geometry of the Model S. The presses can shape a sheet of metal in roughly 6 seconds. Subassembly: The various pieces of metal are put together using a combination of joining techniques,including welding and adhesion. This creates the body of the vehicle.Paint: The body of the vehicle is then moved to the paint shop. After painting is completed, the body moves through a 350° oven to cure the paint, followed by a sanding operation that ensures a clean surface. General assembly: After painting, the vehicle body is moved to the final assembly area. Here, assembly workers and assembly robots insert the various subassemblies,…
There are 3 servers in the checkout area. The interarrival time of customers is 2 minutes. The processing time is 5 minutes.

What will be the impact on the average number of customers in service if one more server is added? Multiple Choice Remains the same at 2.5 Increases from 1.25 to 2.5 Decreases from 2.5 to 1.25 Remains the same at 1.25
Hilltop Restaurant is located in Dempsey Hill. The restaurant has a capacity of 35 tables to serve customers. When doing its capacity planning and evaluating operational performance, the restaurant adopts the concept of “customer group” and uses it as unit of measurement to measure the workload in the service process. A customer group is a group of one or more people who arrive, get seated at a table, eat and depart. On average, a customer group takes 70 minutes to eat dinner, and then another 25 minutes to eat dessert. On average, a customer group generates a profit of $100 on dinner, and $30 on dessert. Now assume that Hilltop leases new space to open a “dessert bar” next door, and has opened up the wall between the two units to allow inside access from the restaurant to the dessert bar. The dessert bar can accommodate 15 tables. With this change, a customer group arrives and is seated at a table in Hilltop restaurant as usual. However, when the customer group finishes eating dinner,…
