Charles Lackey operates a bakery in Idaho Falls, Idaho. Because of its excellent product and excellent location, demand has increased by 45% in the last year. On far too many occasions, customers have not been able to purchase the bread of their choice.Because of the size of the store, no new ovens can be added. At a staff meeting, one employee suggested ways to load the ovens differently so that more loaves of bread can be baked at one time. This new process will require that the ovens be loaded by hand,requiring additional manpower. This is the only production change that will be made in order to meet the increased demand. The bakery currently makes 1,500 loaves per month. Employees are paid $8 per hour. In addition to the labor cost, Charles also has aconstant utility cost per month of $600 and a per loaf ingredient cost of $0.40.Current multifactor productivity for 640 work hours per month = loaves/dollar (round your response to three decimal places).After increasing the number of work hours to 928 per month, the multifactor productivity =loaves/dollar (round your response to three decimal places).The percentage increase in productivity = % (enter your response as a percentage rounded to two decimal places).

Productivity reflects the efficiency with which an item is being produced with the given inputs.…

Charles Lackey operates a bakery in Idaho Falls,Idaho. Because of its excellent product and excellent loca-tion, demand has increased by 25% in the last year. On far toomany occasions, customers have not been able to purchasethe bread of their choice. Because of the size of the store, nonew ovens can be added. At a staff meeting, one employeesuggested ways to load the ovens differently so that moreloaves of bread can be baked at one time. This new processwill require that the ovens be loaded by hand, requiring addi-tional manpower. This is the only thing to be changed. If thebakery makes 1,500 loaves per month with a labor produc-tivity of 2.344 loaves per labor-hour, how many workers willLackey need to add? (Hint: Each worker works 160 hours permonth.)
Mack’s guitar fabrication shop produces low cost, highly durable guitars for beginners. Typically, out of the 100 guitars that begin production each month, only 80 percent are considered good enough to sell. The other 20 percent are scrapped due to quality problems that are identified after they have completed the production process. Each guitar sells for $300. Because some of the production process is automated, each guitar only requires 10 labor hours. Labor is paid at $10/hour, materials cost is $40/guitar, and overhead is $2,000. a) Calculate the labor and multifactor productivities. b) After some study, the operations manager recommends 3 options to improve the company’s multifactor productivity: (1) increase the sales price by 10 percent, (2) improve quality so that only 10 percent are defective, or (3) reduce labor, material, and overhead costs by 10 percent. Which option has the greatest impact on the multifactor productivity measure?
Partial Operational and Financial Productivity Software Solution (SOS) helps subscriberssolve software problems. All transactions are made over the telephone. For the year 2018, 10 engineers, most of whom are recent graduates, handled 100,000 calls. The average yearly salary for software engineers was $45,000. Starting in 2019, the firm retained and hired only software engineerswith at least 2 years of experience. SOS raised the engineers’ salary to $60,000 per year. In 2019,eight engineers handled 108,000 calls.Required Carry all computations to 4 digits after the decimal point.1. Calculate the partial operational productivity ratio for both years.2.

George has recently joined XYZ Corporation as its vice-president of operations. Within a month of his joining, he started making operational changes in the production process of the department. The lower level workers find it extremely difficult to deal with George’s new ideas and way of thinking. Identify the problem in this case and suggest certain measures to overcome this problem.
A copy center in an office building prepares bound reports for two clients. The center makes multiple copies (thelot size) of each report. The processing time to run, collate, and bind each copy depends on, among other fac-tors, the number of pages. The center operates 250 days per year, with one 8-hour shift. Management believesthat a capacity cushion of 15 percent (beyond the allowance built into time standards) is best. It currently hasthree copy machines. Based on the following table of information, determine how many machines are neededat the copy center Item Client X Client YAnnual demand forecast (copies) 2,000 6,000Standard processing time (hour/copy) 0.5 0.7Average lot size (copies per report) 20 30Standard setup time (hours) 0.25 0.40
Use the following information for the next 3 problems: ABC Company plans to construct a 60,000 sq. ft private warehouse and rent public warehouse as needed. Warehouse inventory turns at the rate of 2 times per month. One pound of merchandise occupies 0.2 cubic feet of warehouse space and can be stacked 10 feet high. Given aisles, and normal operating efficiency, only 50 percent of the total warehouse space is actually used for storage. Assume the facility is being built to size so no additional space is allowed for future product growth. A private warehouse can be constructed for $36 per sq. ft. and can be amortized over 20 years. Annual fixed costs amount to $20 per sq. ft. of total space. The cost of operation is $0.03 per pound of throughput. Space may also be rented for a storage charge on inventory of $0.06 per pound per month and a handling charge of $0.05 per pound of throughput. Monthly demands for a typical year are as follows: Month Demand (lb) Jan 2,000,000…
An airline company must plan its fleet capacity and its long-term schedule of aircraft usage. For one flight segment, the average number of customers per day is 70, which represents a 65 percent utilization rate of the equipment assigned to the flight segment. If demand is expected to increase to 80 customers for this flight segment in three years, what capacity requirement should be planned? Assume that management deems that a capacity cushion of 15 percent is appropriate. The needed capacity requirement is enter your response here customers per day.

Old Pueblo Engineering Contractors creates six-month “rolling” schedules, which are recomputed monthly. For competitive reasons (it would need to divulge proprietary design criteria, methods, and so on), Old Pueblo does not subcontract. Therefore, its only options to meet customer requirements are (1) work on regular time; (2) work on overtime, which is limited to 30 percent of regular time; (3) do customers’ work early, which would costan additional $5 per hour per month; and (4) perform customers’ work late, which would cost an additional $10 per hour per month penalty, as provided by their contract. Old Pueblo has 25 engineers on its staff at an hourly rate of $30. The overtime rate is $45. Customers’ hourly requirements for the six months from January to June are January 5000 February 4000 March 6000 April 6000 May 5000 June 4000 Develop an aggregate plan using a spreadsheet.

Yost-Perry Industries (YPI) manufactures a mix of affordable guitars (A, B, C) that are fabricated and assembled at four different processing stations (W, X, Y, Z). The operation is a batch process with small setup times that can be considered negligible. The product information (price, weekly demand, and processing times) and process sequences are shown below. Purchased parts and raw materials (shown as a per-unit consumption rate) are represented by inverted triangles. YPI is able to make and sell up to the limit of its demand per week with no penalties incurred for not meeting the full demand. Each workstation is staffed by one highly skilled worker who is dedicated to working on that workstation alone and is paid $15 per hour. The plant operates one 8-hour shift per day and operates on a 5-day work week (i.e., 40 hours of production per person per week). Overhead costs are $9,000/week. Which of the four workstations, W, X, Y, or Z has the highest aggregate workload, and thus…
