Seattle's Top Coffee owns and operates a chain of popular coffee stands that serve over 30 different coffee-based beverages. The constraint at the coffee stands is the amount of time required to fill an order, which can be considerable for the more complex beverages. Sales are often lost because customers leave after seeing a long waiting line to place an order. Careful analysis of the company's existing products has revealed that the opportunity cost of order filling time is $2.70 per minute. The company is considering introducing a new product, praline cappuccino, to be made with pecan extract and molasses. The variable cost of the standard size praline cappuccino would be $0.30 and the time required to fill an order for the beverage would be 40 seconds Required: What is the minimum acceptable selling price for the new praline cappuccino product?

12-15 The wheat harvesting season in the American Midwest is short, and most farmers deliver their truckloads of wheat to a giant central storage bin within a two-week span. Because of this, wheat-filled trucks waiting to unload and return to the fields have been known to back up for a block at the receiving bin. The central bin is owned cooperatively, and it is to every farmer’s benefit to make the unloading/storage process as efficient as possible. The cost of grain deterioration caused by unloading delays, the cost of truck rental, and idle driver time are significant concerns to the cooperative members. Although farmers have difficulty quantifying crop damage, it is easy to assign a waiting and unloading cost for truck and driver of $18 per hour. The storage bin is open and operated 16 hours per day, 7 days per week, during the harvest season and is capable of unloading 35 trucks per hour according to an exponential distribution. Full trucks arrive all day long (during the hours…

erex Corporation is a global manufacturer of aerial work platforms and materials processing machinery. They design, build and support products such as large lifting equipment used in construction. The company makes most pieces to order and customizes them to meet customers’ unique preferences.Terex maintained a manual system for yard management at their transfer centre in Washington that is always full of lifting equipment, which generated excessive costs for what should have been a relatively simple process of locating customers’ units to prepare them for delivery. A wallboard and sticker system was a low-tech solution for identifying equipment items in the yard at Terex. While inexpensive in itself, the solution cost around six minutes every time an employee had to locate a unit in the yard. It also required a considerable number of hours to be spent each month taking physical inventories. After a successful pilot, the company approved a new solution, replacing stickers, yard maps,…
I'm working on creating a digital simulation model using FlexSim software to represent the flow of four distinct products within a warehouse setting. Here's the process: 1. **Model Overview**: - Each product arrives at a temporary waiting area. - Products then proceed to one of four inspection machines, each dedicated to a specific product type. - After inspection, products are sent to a scanning station before being transported to one of four storage racks. 2. **Simulation Parameters**: - Product arrivals follow an exponential distribution with an average of 12 seconds. - Inspection times are exponentially distributed with an average of 6 seconds per machine. - Scanning time is fixed at 4 seconds. - The simulation will run for 50,000 seconds, and queue capacity is set to 10,000. 3. **Model Construction and Analysis**: - Build the digital model in FlexSim, detailing the layout and process flow. - Provide screenshots of key settings for objects such as Queues,…
A lab provides ultrasound service to patients. The service process consists of two steps: 1. Registration. Performed by a receptionist (Salary rate = $25/hr; Process time = 6 minutes/patient) 2. Ultrasound scan. Performed by a technician (Salary rate = $30/hr; Process time = 20 minutes/patient) Note that the ultrasound images need to be read by radiologists, but we assume that they have an ample capacity and thus will not model the role in the service process. Currently, the lab has 2 receptionists and 3 technicians. The manager anticipates demand to grow to 14 patients/hr in the near future. Thus, he plans to hire more receptionists and/or technicians to increase the service capacity to at least 14 patients/hr. What would be the extra payroll cost (in dollars per hr)?
10. Customers arrive an average of 8 per hour and an average of 12 customers can be served in an hour. Assume this is an M/M/1 model.

The following build-up diagram tracks the number of customers for a single-server queueing system (e.g., an ATM machine) from 10:00am to 10:15am on a certain day. The number of customers shown in the chart includes both those in service and waiting in line. Build-up diagram 3 2 1 # of Customers in system (in service + waiting) 0 10:00 10:01 10:02 10:03 10:04 10:07 10:09 We will call the customer who arrived the earliest during this time span the first customer, the customer who arrived the second earliest the second customer, etc.. The service discipline is first-come-first-served (FCFS). According to the diagram, what is the service time of the first customer in minutes?
