Scenario 3: Falsifying Attendance Jason, a Junior System Administrator with the Management Information Systems Department, clocked in 4 minutes and 27 seconds late for work this morning. While he won’t get fired for it, being late this once means that he will not receive the perfect attendance incentive which he needs to make ends meet, given his daughter’s recent series of hospitalizations. It’s not that Jason didn’t make an effort to be there on time. He actually arrived in the office five minutes early but was unable to clock in immediately because his direct superior, Raffy, asked him for an informal project progress report as soon as he walked in the door. As a Junior System Administrator, Jason has access and the capability to edit the company’s attendance records. He figures that since he was unable to punch in only because of his boss, it wouldn’t hurt to edit the timestamp on his attendance for today.

Question related to queing theory An overhead crane of ABC Ltd. moves jobs from one machine to another and must be used every time a machine requires loading or unloading. The demand for service is random. Data taken by recording the elapsed time between service calls followed an exponential distribution having a mean of a call every 26 minutes. In a similar manner, the actual service time of loading or unloading took an average of 10 minutes. If the machine time is valued at Rs. 8.50 per hour, how much does the downtime cost per day?

Problem 15-31 (Algorithmic) Mid-West Publishing Company publishes college textbooks. The company operates an 800 telephone number whereby potential adopters can ask questions about forthcoming texts, request examination copies of texts, and place orders. Currently, two extension lines are used, with two representatives handling the telephone inquiries. Calls occurring when both extension lines are being used receive a busy signal; no waiting is allowed. Each representative can accommodate an average of 10 calls per hour. The arrival rate is 16 calls per hour.

99) PLEASE HELP ME WITH THIS!! L. Winston Martin (an allergist) has an excellent system for handling his regular patients who come in just for allergy injections. Patients arrive for an injection and fill out a name slip, which is then placed in an open slot that passes into another room staffed by up to three nurses. The specific injections for a patient are prepared, and the patient is called through a speaker system into the room to receive the injection. At certain times during the day, patient load drops and only one nurse is needed to administer the injections. Let's focus on the simpler case of the two--namely, when there is one nurse. Also, assume that patients arrive in a Poison fashion and the service rate of the nurse is exponentially distributed. During this slower period, patients arrive with an interarrival time of approximately 4 minutes. It takes the nurse an average of 2.80 minutes to prepare the patients' serum and administer the injection. a. What is the average…
DEMU 2103, va assignmen QUESTION 3 Metropolitan General Hospital is a city-owned and operated public hospital. Its emergency. room is the largest and most prominent in the city. Approximately 70% of emergency cases in the city come or are sent to Metro General's emergency room. As a result, the emergency room is often crowded and the staff is overworked, causing concern among hospital administrators and city officials about the quality of service and health care the emergency room is able to provide. One of the key quality attributes administrators focus on is patient waiting time that is, the time between when a patient checks in and registers and when the patient first sees an appropriate medical staff member. Hospital administration wants to monitor patient waiting time using statistical process control charts. At different times of the day over a period of several days, patient waiting times were recorded at random with the following results: Sample 1 2 3 4 5 6 7 8 9 10 1 27 22 16…
