Mr. Elf owns a show store. Currently, he has 10 pairs of shoes that require resoling and polishing. He has a machine that can resole one pair of shoes at a time, and the time required for
the operation varies with the type and condition of the shoe and the type of sole that is used. Shoes are polished on a machine dedicated to this purpose as well, and polishing is always
done after resoling. His assistant generally does the polishing while Mr. Elf does the resoling. The resoling and polishing times (in minutes) are:

A call center employs 1,425 agents. Every month 57 employees leave the company and 57 new employees are hired.
a. How long on average does an agent work for this call center (in months)
Suppose the cost of hiring and training a new agent is $1,140. The manager of this call center believes that increasing agents’ salaries would keep them working longer at the company. The manager wants to increase the average time that an agent works for the call center to 36 months, or three years.
b-1. Given the current average working time for agents at this call center, determine the current annual cost for hiring and training.
b-2. Assuming the average time that an agent works for the call center is increased to 36 months, determine the new annual cost for hiring and training.
b-3. If the time an agent works for the call center is increased to 36 months on average, how much could the company save on hiring and training costs over a year?

The respective repair times (in days) and the remaining days before the due date are given in the table below.arrow_forwardA large building may require an automated alarm system which monitors and controls all fire and security alarms in the building. Normally, the building is divided into zones and a number of alarms are associated with each zone. Alarms alert a central manned control area who may pass these on to the emergency services or may respond personally.Factors which have to be taken into account in building such a system are:Ø If the control area is unmanned and an alarm is activated this alarm should not be ignored if it is potentially serious. Emergency services should be automatically called.Ø Some but not all parts of the building may be equipped with sprinkler systems or systems to shut down electrical equipment. These should be activated if a fire alarm is confirmed. They should not be activated if there are people in the same room.Ø The building may be equipped with direction indicators which illuminate the route to the nearest exit. These should be activated when a fire alarm is…arrow_forwardIn a transition probability matrix, the sum of every column is 1. True Falsearrow_forward
- There are two companies manufacturing drones. Company A manufactures mass market drones, while company B manufactures customised drones according to customers’ requirements. In 2020, company A produces 3,200 drones, 3% of which were found to be defective and cannot pass the quality check. Company A employs 5 workers working an average of 8 hours a day in the drone production, and they worked 200 working days in 2020.In contrast, company B produces 900 drones, 10% of which were found to be defective and cannot pass the quality check. Company B employs 3 workers working an average of 6 hours a day in the drone production, and they worked 170 days in 2020.

His customers include individual homeowners and businesses that subscribe to his service for lawn care beginning in the spring and ending in the fall with leaf raking and disposal. Thus, when he begins his service in April he generally has a full list of customers and does not take on additional customers any time after the first of June, it is difficult to find new customers, since most people make lawn service arrangements forth the entire summer. Mark employs five crews, with three to five workers each, to cut grass during the spring and summer months. A crew normally works 10-hour days and can average cutting about 25 normal-size lawns of less than a half-acre each day. A crew will normally have one heavy-duty, wide-cut riding mower, a regular power mower, and trimming equipment. When a crew descends on a lawn, the normal procedure is for one person to mow the main part of the lawn with the riding…arrow_forwardA roller coaster is being designed for a new theme park. Two "trains" are on the track at any given time. One train is being unloaded/reloaded while the other is moving along the track. The track itself takes 10 minutes to complete. The train being loaded should depart before the arriving train is no closer than one minute away. Each car of a train accommodates four people. Loading a car is estimated to take 6 seconds per passenger. Unloading is estimated to take 6 seconds per passenger. Suppose that (unlike actual roller coasters), only one car can be loaded or unloaded at a time. Unloading can NOT occur at the same time as loading. In order to maximize the number of potential passengers, how many cars should the train be made up of? Round your answer to the nearest whole car.arrow_forward
- Subject: FUNDAMENTALS OF BUSINESS ANALYTICS Problem: The Supermarket contains over 14,000 transactions made by supermarket customers over a period of approximately two years. (The data are not real, but real supermarket chains have huge data sets just like this one.) A small sample of the data appears in in the Figure below, Column B contains the date of the purchase, column C is a unique identifier for each customer, columns D–H contain information about the customer, columns I–K contain the location of the store, columns L–N contain information about the product purchased (these columns have been hidden to conserve space), and the last two columns indicate the number of items purchased and the amount paid. Question: Based on the given problem and picture provided, determine which variables are categorical and numerical?arrow_forwardA company produces a product at two plants, 1 and 2. The unit production cost and production capacity during each period are: Unit production cost $ capacity Plant 1 (period 1) 33 7 Plant 1 (period 2) 43 4 Plant2 (period 1) 30 9 Plant 2 (period 2) 41 9 The product is instantaneously shipped to the company's only customer according to the unit shipping costs below: Period 1 Period 2 Plant 1 to customer $51 $60 Plant 2 to customer $42 $71 If a unit is produced and shipped during period 1, it can still be used to meet a period 2 demand, but a holding cost of $13 per unit in inventory is assessed. At the end of period 1, at most six units may be held in inventory. Demands are as follows: period 1, 9; period 2, 11. Formulate an MCNFP that can be use to minimize the cost of meeting all demands on time.

Julia Faure, controller of Beeson Co., has suggested that all orders received before the end of the fiscal year be shipped by midnight, December 31st even if shipping department must work overtime. Since Beeson Co. ships all merchandise FOB shipping point, it would record all such shipments as sales for the year ending December 31st, thereby offsetting some of the decreases in sales and operating income.Discuss whether Julia Faure is behaving in a professional manner and what are the implications of her actions?arrow_forward
- The Decision Sciences Department is tyring to determine whether to rent a slow or fast copier. The department believes that an employee's time is worth $15/hour. The slow copier rents for $4/hr, and it takes an employee an average of 10 minutes to complete copying. The fast copier rents for $15/hr, and it takes an employee an average of 6 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?

Each day is divided into 6 four-hours periods, which requires different number of nurses., as shown in the table below: Time Period Index Time Period Covered 7am - 11am. 11am-3pm 3pm - 7pm 7pm - 11pm 11pm-3am 3am - 7am 1 2 3 4 5 6 Required Number of Nurses 7 9 12 5 4 3 The shifts of full-time nurses can begin at the start of any of the four-hour periods. Hospital policy requires that there must be at least two full-time nurses at each time period. Also, the number of part-time nurses cannot exceed the number of 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.
