- A Printed Circuit Board (PCB) machine installs integrated circuits onto a board. Before starting to produce a board, the PCB machine requires a 16-minute setup. Once in production, the PCB machine requires only 0.19 minute per board. a. Currently, the PCB machine produces 525 boards between setups. Given this operating process, what is the capacity of the PCB machine (in boards per min)? b. Currently, the PCB machine produces 525 boards between setups. Given this operating process, what is the utilization of the PCB machine? c. Say the PCB machine produces 400 boards s between setups and demand is 2 boards per minute. Given the operating process, what is the avergae inventory of boards anf the PCB machine? d. Demand for boards occurs at the rate of 2 boards per minute. What is the smallest batch size such that the PCB machine does not constrain the flow rate through the process?A production line has three stations and the first station can process a unit in 10 minutes. The second station has two identical machines, each of which can process a unit in 12 minutes. The third station can process a unit in 8 minutes. What is the hourly capacity of this production line?A company producing a standard line and a deluxe line of dishwashers has the following time requirements (in minutes) in departments where either model can be processed. Standard Deluxe Stamping 3 6 Motor Installation 10 10 Wiring 10 15 The standard models contribute $20 each and the deluxe $30 each to profits. Because the company produces other items that share resources used to make the dishwashers, the stamping machine is available only 30 minutes per hour, on average. The motor installation production line has 60 minutes available each hour. There are two lines for wiring, so the time availability is 90 minutes per hour. Write the formulation for this linear program. What are the optimal daily production quantities of each product and the optimal daily profit?
- Customers are served in a process with two resources. The first resource has a capacity of 45 customers per hour. The capacity of the second resource is 32 customers per hour. The first resource has 9 workers and the second resource has 3 workers. Demand for this process is 29 customers per hour. What is the average labor utilization? ______percentYou operate a process with three workstations; the cycle times are given below. A regular batch is 52 units and your production line runs 5 hours per day. Calculate how many hours lead time is required to ship a batch, assuming there are no orders ahead in the queue and there is no inventory to fill the order. Workstation 1 has a cycle time of 2 minutes per unit Workstation 2 has a cycle time of 3 minutes per unit Workstation 3 has a cycle time of 3 minutes per unit Select one: a. 1560.00 b. 8.00 c. 1560.00 d. 90.00 e. 2340.00RideShare offers short-term rentals of vehicles that are kept in small lots in urbanneighborhoods with plenty of potential customers. With one lot, it has eight cars. Theinterarrival time of potential demand for this lot from its base of customers is 40 minutes.The average rental period is five hours. If a customer checks availability of vehicles in thislot online and finds that they are all rented for the desired time, the customer skips rentingand finds alternative arrangements. However, because customers pay a monthly fee tosubscribe to this service, RideShare does not want customers to be disappointed too often.a. What is the offered load?b. What is the implied utilization?c. What is the capacity of the process (rentals per hour)?d. What is the probability that all eight cars are rented at the same time?e. How many customers are served every hour?f. What is the utilization of the cars?g. How many cars should it have in this lot to ensure that it serves at least 90 percent ofdemand?
- A toy firm produces drums sequentially on three machines—A, B, and C—with cycle times of 3, 4, and 6 minutes, respectively. (a) Determine the optimum efficiency and output rates for adding one, two, ... , six more machines. (b) assume now that two identical lines are operating, each with machines A, B, and C. If new machines can be shared between the lines, how should one, two and then three new machines be added What are the resulting efficiencies and outputs of the two lines? is it always best to equally share extra machines between the two lines?You currently employ 48 nurses who work 12 hour shifts and get 90 minutes for breaks during their shift. Nurses are available for rounding (i.e., caring for patients) for 75% of their time. Rounding demand is 1,512 minutes per shift. How many minutes should a nurse spend with each patient during rounds to keep up with demand?Kitty Wonderland (KW) makes toys for cats. KW’s managers have recently learned that they can calculate the average waiting time for an order from the time an order is received and the time it is manufactured. They have asked for your help and have provided the following information. Expected number of orders for the product: 2,000 Manufacturing time per order: 4 hours Annual machine capacity in hours: 10,000 After learning about the average waiting time, KW’s managers are confused. They do not understand why, if annual machine capacity is greater than the average number of orders for the product, there would be any waiting time at all. Briefly answer the following questions Calculate the average waiting time per order. The managers have asked for your suggestions on what they can do to minimize or eliminate waiting time. How would you respond? Management is expecting sales to increase. Will average waiting time increase or decrease? Explain briefly.
- Panini, a popular sandwich shop, offers 3 types of sandwiches: grilled vegetables, grilled chicken, and pastrami. The table below provides demand data: Grilled Vegetables Grilled Chicken Pastrami Demand per hour 25 9 12 There are up to five steps in the process of making sandwiches listed below with activity times (if no activity time, then than step is not done for that sandwich).

Sales staff are assigned standard shifts (1st shift usually takes place between the hours of 9 a.m. and 5 p.m. 2nd shift is worked between 5 p.m. and 1 a.m. 3rd shift typically takes place between the hours of 12 a.m. and 8 a.m.), and the number of customers arriving per shift averages 40, Poisson distributed. A salesperson can deal with one customer in 5 minutes on average and costs the company $100 per shift in salaries and fringe benefits. Service times closely follow an exponential distribution. The manager is reviewing the number of salespersons to schedule for each shift. The cost of customers waiting before they receive service has been estimated at $2 per minute in terms of lost sales and loss of goodwill. a. If management wants to minimize the cost of both sales staff and customer wait times, how many salespersons should be working in each shift? b. What is the cost per shift to the company if they use the number of salespersons you…Cakes baked by the Freshfood Bakery are transported from the ovens to be packaged by one of three wrappers.
