The time from when a patient is discharged from NorthShore Hospital to the time the discharged patient’s bed isready to be assigned to a new patient is referred to as thebed assignment turnaround time. If the bed turnaroundtime is excessive, it can cause problems with patient flowand delay medical procedures throughout the hospital. Thiscan cause long waiting times for physicians and patientsthus creating customer dissatisfaction. The admissions RNhas assigned a patient care associate to measure the bedturnaround time for a randomly selected bed each morning,afternoon, and evening for 30 days. Following are the bedturnaround time sample observations:a. Develop an x-chart to be used in conjunction with anR-chart using 3 limits to monitor the bed turnaroundtimes and indicate if the process is in control usingthese charts.b. Is the hospital capable of consistently achieving bedturnaround times of 120 minutes 15 minutes withoutimproving the process?
A manufacturing company has a small production line dedicated to the production of a particular product. The line has four stations in serial. Inputs arrive at station 1 and the output from station 1 becomes the input to station 2. The output from station 2 is the input to station 3 and so on. The output from station 4 is the i nished product. Station 1 can process 2,700 units per month, station 2 can process 2,500/month, station 3 can process 2,300/month, and station 4 can process 2,100/month. What station sets the maximum possible output from this system? What is that maximum output number?
A printing shop receives an average of 1 order per day.The average length of time required to complete an orderis .5 day.

At the University Hospital, five blood samples must bescheduled through a blood-testing laboratory. Eachsample goes through up to four different testing stations.The times for each test and the due dates for eachsample are as follows:Sample Test Station/Hours Due Date (hours)1 A/1, B/2, C/3, D/1 62 B/2, C/3, A/1, D/4 103 C/2, A/3, D/1, C/2 84 A/2, D/2, C/3, B/1 145 D/2, C/1, A/2, B/4 12a. Using a Gantt chart, schedule these five samples in priority order of earliest due date first.b. Assume that the capacity of each test station (A, B, C and D) is doubled. Prepare an FCS for this situation.c. What are the bottleneck work centers in part a of the problem. Suggest capacity additions that might be needed.

b) A company receives parts from suppliers to be used in its manufacturing departments. The quality control department must perform two operations when shipments are received: Operation A – draw a random sample, package, and deliver to testing; and Operation B – test the materials and issue a disposition report. There are currently six shipments waiting to be processed. The time estimates for processing these six shipments through quality control are given in the table below.

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.

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…
n a manufacturing process, a molded part spends 7 hours in inventory before being placed in a deburring machine, where the part is processed for 2 minutes. After deburring, the part spends 4 hours in inventory waiting for its turn on the polishing machine. The part then spends 7 minutes in polishing before waiting 6 hours in line to be painted. The part goes through a painting process that takes 7 minutes, then spends 11 hours in inventory before being shipped to the customer. What is the percentage of value-added time for the part?

The OR is available for 12 hours a day; the hospital has decided to not perform any procedures between 7pm and 7am. This time is equally divided across three surgeons. The standard procedure time for the knee surgery done at the clinic is 1h. The cleaning and housekeeping that needs to happen after each procedure takes 20 minutes. Almost all of this time could be saved if the cleaning crew were notified earlier on. 10 minutes are spent on patient preparation / anesthesia work before each procedure. (Note: this is not part of the 60-minute procedure time). Proposals have been evaluated to move these 10 minutes to outside the OR, and there exists no medical reason that would prohibit doing this.) A surgeon only starts a case if all of the work associated with the case (preparation, procedure, and cleaning) can be completed in the 4h allotted to each surgeon. Surgeons never start BEFORE their allotted time. Though the clinic aims to operate 7 days a week, holidays, vacation, and…
