A community health system's nurse team consists of 12 nurses working in the local community. It takes a nurse 1.25 hours to complete one patient visit (including travel times and breaks). Round "Utilization" to a whole percent, and "Cycle Time" to 1 decimal. What is the capacity of the nurse team over the course а. of a 12 hour work day? per 12 hour work day Assuming the demand for the nurses is 80 patients per b. day, what is the utilization of the nurse team? percent Assuming the demand for the nurses is 80 patients per day, what is the cycle time? с. minutes per patient
The 4M company has a lathe as the centerpiece of the plant's work. The jobs arrive according to a Poisson process with an average rate of 2 per day. The processing time of each job is exponentially distributed with an average of 1/ 4 day. Since the jobs are large, if they are not in process they are stored in a warehouse some distance from the machine. However, to save time in bringing them in, the production manager proposes to add space for 3 in-process jobs in addition to the one on the lathe (the rest will continue to be stored). With this proposal, what proportion of the time will the space next to the lathe be adequate for the waiting jobs? Calculate your answer using the formulas available.
Station 1 6 min/unit Station 2 Machine A 15 min/unit 6 minutes 20 minutes 91 minutes 226 minutes Station 2 Machine B 15 min/unit Station 3 10 min/unit Station 4 Machine A 60 min/unit Station 4 Machine B 60 min/unit Station 4 Machine C 60 min/unit A manufacturing plant has four stations in the assembly line (illustrated in the image above). A unit needs to be processed at either Machine A or Machine B for Station 2 (parallel lines, both lines performing the same operations). The box is then processed at Station 3. After that, the unit needs to be processed at either Machine A, Machine B or Machine C in Station 4 before leaving the production line. The process time of each station/machine is indicated in the flowchart. What is the process cycle time of this system measured in minutes?
Consider a workstation that has one maintenance mechanic to repair failed machines. We can think of the mechanic as the processor (scarce resource) and the machines awaiting repair as the jobs. Let us assume that six machines are down, with estimated repair times given here, and that no new machines fail. 1 2 3 Job (fix machine #) Processing time 10 (hours) Job 1 2 3 4 5 6 2 Compute the flow time for each job using both the FCFS rule and the SPT rule, and compare the average flow times. Round your answers for average values to the nearest whole number. FCFS Rule 9 Flow Time (hours) Average flow time (FCFS rule): 4 5 6 1 8 6 hours
The Waterfall Buffet in the lower level of the National ArtGallery serves food cafeteria-style daily to visitors andemployees. The buffet is self-service. From 7:00 A.M. to9:00 A.M. customers arrive at the buffet at a rate of eight perminute; from 9:00 A.M. to noon, at four per minute; fromnoon to 2:00, at 14 per minute; and from 2:00 P.M. to closing at 5:00 P.M., at eight per minute (Poisson distributed).All the customers take about the same amount of time toserve themselves and proceed to the buffet. Once a customer goes through the buffet, it takes an average of0.4 minute (exponentially distributed) to pay the cashier.The gallery does not want a customer to have to wait longerthan four minutes to pay. How many cashiers should beworking at each of the four times during the day?

DreamInflate is a balloon manufacturing company. Balloon manufacturing consists of seven work stations, each performing a single step as indicated in the table below. There are five workers manned for the seven work stations as shown. Assume the workers are paid $15 per Worker Task Sequence Processing Time (secs/balloon) Task Dye production Electrocharging Dipping (Cold and Hot) Mortar Dipping Balloon inflation and delaltexing Vulcanization Inspection/Testing 1 30 w1 20 3 35 W2 25 W3 30 W4 6. 45 W5 7 40 hour. Each balloon pack is sold for $6 and has a variable cost of $1. The company has fixed costs of $200 per hour. There is more demand than the overall production system can provide. Based on the information provided, answer the following questions: • What is the cost of direct labor for balloons? • How much profit does DreamInflate make every hour? (note that the cost of direct labor is also a variable cost). What would the profit of DreamInflate be if the variable costs were 10…
d CE Additional Algo 5-11 Attrition Losses and Yields A process has three resources and two types of flows. The first flow has a demand of 20 units per day, and the second flow has a demand of 40 units per day. The first flow type visits all three resources, while the second flow type only visits the first and the third resources. The capacity is 100 units per day at the first resource, 40 units per day at the second resource, and 70 units per day at the third resource. 1. What is the demand total for each resource?
