A manager is simulating the number of times a machine operator stops a machine to make adjustments. After careful study themanager found that the number of stops ranged from one to five per cycle and that each number of stops was equally likely. Using therandom numbers 0.17 and 0.47 (in that order), determine how many stops for adjustments each of the next two cycles will have.The first cycle will havestops and the second cycle will havestops.

The number of stops ranged from one to five per cycle and that each number of stops was equally…

Answered: The first cycle will have stops and the…

WhatYouNeed is an online retailer with operations in Northern Indiana. Their network includes five big warehouses. All of the warehouses are fully automated: packaging is performed by robots on top of electric conveyors. Although the company has saved a lot in labor costs by the use of this packaging line, it has resulted in some excessive waste of material. After some analysis of this waste issue, the company has discovered that the number of product types that are assigned to the packaging line is strongly correlated with the amount of wasted material. Based on this insight, their operations manager has built a mathematical expression that estimates the expected amount of waste from the packaging line as a function of the number of product types in it. The expression is as follows: W = (n-93)2 – (n-88) + 227 In this expression, n is the number of product types you are packing on the line and W is the hourly waste of packaging material (in lbs). Based on this expression, how much will…
OVERBOOKED: FRONT OFFICE PERSPECTIVE Overbooking is an accepted hotel and airline practice. Many questionthe practice from various standpoints, including ethical and moral.Industry executives, however, argue that there is nothing moreperishable than a vacant room. If it is not used, there is no chance toregain lost revenue. Hotels need to protect themselves becausepotential guests frequently make reservations at more than one hotelor are delayed and, therefore, do not show up. The percentage of no-shows varies by hotel and location but is often around five percent. In a 400-room hotel, that is 20 rooms, or an average loss ofapproximately $2,600 per night. Considering these figures, it is notsurprising that hotels try to protect themselves by overbooking.Hotels look carefully at bookings: Whom they are for, what rates theyare paying, when they were made, whether they are for regular guestsor from a major account (a corporation that uses the hotel frequently),and so on.

Consider two different workstations. Each workstation consists of machines A and B, respectively. Machine A has a mean effective process time of 1.0 hours and an c² of 0.25. Machine B has a mean effective process time of 0.85 hour and an c² of 4. Assume the part arrival and service processes follow a general distribution. 1 (a) For an arrival rate of 0.92 job per hour with c2 = 1, which machine will have a shorter average cycle time? (b) Now put one more machine of type A at the station and double the arrival rate (i.e., double the capacity and the throughput). What happens to cycle time?
Consider the following process at a pharmacy. Customers drop off their prescriptions either in the drive-through counter or in the front counter of the pharmacy. Customers can request that their prescription be filled immediately. In this case, they have to wait between 15 minutes and one hour depending on the current workload. Most customers are not willing to wait that long, so they opt to nominate a pickup time at a later point during the day. Generally, customers drop their prescriptions in the morning before going to work (or at lunchtime) and they come back to pick up the drugs after work, typically between 5pm and 6pm. When dropping their prescription, a technician asks the customer for the pick-up time and puts the prescription in a box labelled with the hour preceding the pick-up time. For example, if the customer asks to have the prescription be ready at 5pm, the technician will drop it in the box with the label 4pm (there is one box for each hour of the day). Every hour, one…
Problem 2-4 (Algo) A company that makes shopping carts for supermarkets and other stores recently purchased some new equipment that reduces the labor content of the jobs needed to produce the shopping carts. Prior to buying the new equipment, the company used 5 workers, who together produced an average of 80 carts per hour. Workers receive $12 per hour, and machine cost was $30 per hour. With the new equipment, it was possible to transfer one of the workers to another department, and equipment cost increased by $11 per hour, while output increased by 5 carts per hour. a. Compute labor productivity under each system. Use carts per worker per hour as the measure of labor productivity. (Round your answers to 3 decimal places.) Before After b. Compute the multifactor productivity under each system. Use carts per dollar cost (labor plus equipment) as the measure. (Round your answers to 3 decimal places.) Before After carts per worker per hour carts per worker per hour Labor productivity…
Consider two arrival processes. The coefficient of variation of process 1 is CV1, and the coefficient of variation of process 2 is CV2. It is possible that CV1=CV2 even though the average interarrival time is larger in process 1 compared to process 2. T or false ?
Solve the question below using the attached excel templates with formulas for renting both slow and fast copies (labeled in the excel tabs). Question: The Decision Sciences Department is trying to determine whether to rent a slow or a fast copier. The department believes that an employee’s time is worth $15 per hour. The slow copier rents for $4 per hour, and it takes an employee an average of 10 minutes to complete copying. The fast copier rents for $15 per hour, and it takes an employee an average of six minutes to complete copying. On average, four employees per hour need to use the copying machine. (Assume the copying times and interarrival times to the copying machine are exponentially distributed.) Which machine should the department rent to minimize expected total cost per hour?

Problem 2: Suppose you observe the following arrivals and departures from a single-server queueing system. Observations begin at time 100.0 (with no one in the queue) and end at 120.0. Customer Time Customer # Arrives to Queue 83 84 85 86 87 88 89 90 91 100.4 101.5 105.1 106.8 108.1 113.5 117.9 118.0 119.9 Time Customer Departs from Queue and Goes Into Service 102.3 108.3 109.5 110.6 112.9 114.2 117.9 119.2 After 120.0 Time Customer Departs From Server 108.3 109.5 110.6 112.9 114.2 116.3 119.2 After 120.0 After 120.0 1) What is the sample mean, sample standard deviation, minimum, and maximum of the waiting time in the queue observed for the customers who arrived at, and departed from, the queue during the time interval [100.0, 120.0]?

Currently a company that designs Web sites has five customers in its backlog. The time since the order arrived, processing time, and promised due dates are given in the following table. The customers are ready to be scheduled today, which is the start of day 190. Customer Time Since Order Arrived (days ago) Processing Time (days) Due Date (days from now) Upper AA 6 18 66 Upper BB 3 24 58 Upper CC 2 32 100 Upper DD 10 22 26 Upper EE 8 12 50 a. Develop separate schedules by using the FCFS and EDD rules. Compare the schedules on the basis of average flow time and average days past due. Part 2 Using the FCFS (first come, first served) decision rule for sequencing the customers, the order is: Sequence 1 2 3 4 5 Customer D E A B C Part 3 Using…
Johnson Fastener and Tool had a six-hour work stoppage yesterday, which means the company does not have its usual number of fasteners stored in inventory. Concerned that the inability to fulfill all current orders may have an adverse effect on some customers, Acme's account executives are notifying all customers, including Henderson Air, that there could potentially be a small delay in delivering some orders. This is an example of:
