The newly-established pediatric department of a local hospital is in need of full-time nurses who will workin 8-hour shift per day and part-time nurses who will work in 4-hour shifts per day. Each day is divided into 6 four-hoursperiods, which requires different number of nurses., as shown in the table below:Time Period IndexTime Period Covered7am - 11am.11am-3pm3pm - 7pm7pm - 11pm11pm-3am3am - 7am123456Required Number ofNurses7912543The shifts of full-time nurses can begin at the start of any of the four-hour periods. Hospital policy requires that theremust be at least two full-time nurses at each time period. Also, the number of part-time nurses cannot exceed the numberof full-time nurses in any time period. Full-time nurses get paid at $160 per shift, while the part-time nurses get paid at$50 per shift. Formulate a linear programming model that will determine the nursing schedule so as to minimize the totalcost.

William Beebe owns a small shoe store. He has 10 pairs of shoes that requireresoling and polishing. He has a machine that can resole one pair of shoes at atime, and the time required for the operation varies with the type and condition of theshoe and the type of sole that is used. Shoes are polished on a machine dedi-cated tothis purpose as well, and polishing is always done after resoling. His assistant generally does the polishing while Mr. Beebe does the resoling.

NewTel is a telephone company with a policy of filling positions internally through promotions, rather than hiring from outside. Until recently, the company had a strong engineering focus and tended to promote people to senior executive positions from the engineering areas. Consequently, almost all of the company's 14 senior executives joined the company over 20 years ago as junior engineers. There is increasing pressure on NewTel to become more market and service oriented. As a result, four people were hired last year from firms to fill new senior executive positions in marketing and service departments. The external hires were necessary because current employees were not sufficiently qualified. Now, there are signs of tension among senior executives, particularly during budget deliberations where there is limited discretionary spending on new corporate activities. The four new hires have been thwarted in their attempts to have the company invest more in marketing and customer…
Abbott Manufacturing produces plastic cases for solar photovoltaic panels and has decided to combine orders from customers to increase work order size, and thereby, make one large production run per model type. Plastic injection molding machines are used to make these parts, and it is time consuming to clean and re-setup the machines between production runs. Each molding machine and operator works one 10-hour shift with a one-hour lunch break and one-half hour for operator breaks.

Chapter 5. (M/M/s/K Model). Leia is responsible for 13 data units in the IT offices in a small business called DataWish. Each data unit runs on an average for 3 weeks and requires an average of ½ or 0.5 weeks to get reset by Leia before it can start up again. If we assign the Poisson distribution to the “arrival” of each data unit for service and an exponential distribution to the actual service provided, answer the following questions: a. The arrival rate would be units per week and the service rate would be units per week. b. Calculate the following operating characteristics for the M/M/s/K system: Utilization Factor (ρ) % Performance Measures P0 (probability that sytem is empty) % L (average units in system) units Lq (average units waiting in queue) units W (average time in the system) weeks Wq (average time in the queue) weeks c.

The medical director of a large emergency clinic faces a problem of providing treatment for patients who arrive at different rates during the day. There are several doctors available to treat patients when needed. If not needed, they can be assigned to other responsibilities (for example, lab tests, reports, x-ray diagnoses) or else rescheduled to work at other hours. It is important to provide quick and responsive treatment, and the medical director feels that, on the average, patients should not have to sit in the waiting area for more than 20 minutes before being seen by a doctor. Patients are treated on a first-come, first-served basis and see the first available doctor after waiting in the queue. The arrival pattern for a typical day is: These arrivals follow a Poisson distribution. The treatment time is 24 minutes on the average with an exponential distribution. Consider the service cost (by doctors) to be $130 per hour. For each patient, the waiting cost when waiting for service…

The new-accounts officer at the Bank enrolls all new customers in checking accounts. During the three-week period in August encompassing the beginning of the new school year at UTT, the bank opens many new accounts for students. The bank estimates that the arrival rate during this period will be Poisson distributed with an average of five (5) customers per hour. The service time is exponentially distributed with an average of 15 minutes per customer to set up a new account. The bank wants to determine the operating characteristics for this system to determine if the current person is sufficient to handle the increased traffic. What is the probability of no customers in the system? What is the average number of customers waiting in the bank? What is the average time the customer spends in the bank? What is the average number of customers waiting in the line? What is the average time that a customer spends in the line? Is the number of tellers sufficient to handle the increase…
