Concept explainers
Charles Lackey operates a bakery in Idaho Falls, Idaho. Because of its excellent product and excellent location, demand has increased by 25% 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 thing to be changed. If the bakery makes 1,500 loaves per month with a labor productivity of 2.344 loaves per labor-hour, how many workers will Lackey need to add? (Hint: Each worker works 160 hours per month.)

- 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…arrow_forwardA 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 0.40arrow_forwardGeorge 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.

- 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.

One of the company’s products, a skate-board, sells for $37.50. The skateboards are manufactured in an antiquated plant that relies heavily on direct labor workers. Thus, variable costs are high, totaling $22.50 per skateboard of which60% is direct labor cost.Over the past year the company sold 40,000 skateboards, with the following operating results: Sales (40,000 skateboards) $1,500,000 Variable expenses 900,000 Contribution margin 600,000 Fixed expenses 480,000 Net operating income $ 120,000 Management is anxious to maintain and perhaps even improve its present level of income from theskateboards. Required: 1. Compute ( a ) the CM ratio and the break-even point in skateboards, and ( b ) the degree of oper-ating leverage at last year’s level of sales. 2. Due to an increase in labor rates, the company estimates that variable costs will increase by$3 per skateboard next year. If this change takes place and the selling…arrow_forward
- CarCity is a big retailer for car parts and accessories. The store stocks different types and sizes of car tire. One of the best selling tires is the Tiger Model R125, which is currently purchased from a factory in Indonesia. An analysis of the purchasing operation shows that approximately 3 labor hours are required to process a purchase order, regardless of the quantity purchased. Salaries in the purchasing Department average OMR 12 per hour, including employee benefits. In addition, a detailed analysis of 15 previous purchase orders showed that OMR 132 was spent on telephone, paper, and other consumables directly related to the ordering process . Shipping cost from Indonesia is OMR 230 for a container. A container has a capacity of 800 tires. The lead time for shipments from Indonesia is 15 days. Finally, CarCity’s financial analysts established a holding cost of 20% for this type of tire. The annual demand for the R125 tire is constant at a rate of 8400 units.
