- Effective capacity is:a) the capacity a firm expects to achieve, given the currentoperating constraints.b) the percentage of design capacity actually achieved.c) the percentage of capacity actually achieved.d) actual output.e) efficiency.arrow_forwardA manager must decide how many machines of a certain type to purchase. Each machine can process 100 customers per day. One machine will result in a fixed cost of $2,100 per day, while two machines will result in a fixed cost of $3,900 per day. Variable costs will be $17 per customer, and revenue will be $45 per customer. a. Determine the break-even point for each range. (Round your answers to the next whole number.) One machine Two machines 4,500 b. If estimated demand is 90 to 120 customers per day, how many machines should be purchased?arrow_forwardThomas Pang Furniture produced 70,000 Executive chairs per week. The effective capacity is 71,000 chairs. The production line operates 5 days per week with two 6-hour shifts per day. The line was designed to process the Executive chairs at the rate of 1,200 per hour. Determine the design capacity, utilization and efficiency for this plant when producing the Executive chair. Thomas Pang Furniture now needs to increase production of the Executive chairs. A second production line will be added. Effective capacity on this second line is the same as the first line at 71,000 Executive chairs. The first line is operating at a higher efficiency but output on the second line will be no more than 75% because the crew will be primarily new hires. Determine the expected output of this second line.arrow_forward
- A biotech firm is considering abandoning its old plant, built 23 years ago, andconstructing a new facility that has 50% more square footage. The original cost of the old facility was $300,000, and its capacity in terms of standardizedproduction units is 250,000 units per year. The capacity of the new laboratoryis to be 400,000 units per year. During the past 23 years, costs of laboratoryconstruction have risen by an average of 5% per year. If the cost-capacity factor, based on square footage, is 0.80, what is the estimated cost of the newlaboratory?arrow_forwardIIn a job shop, effective capacity is only 69 percent of design capacity, and actual output is 76 percent of effective output. What design capacity would be needed to achieve an actual output of 13 jobs per week? What is its effective capacity? a. The Design Capacity needed to achieve the required actual job outputs =Blank 1 (round to whole number) b. The Effective Capacity needed to achieve the required actual job outputs = Blank 2 (round to whole number) Blank 1 Blank 2 Add your answer Add your answerarrow_forwardSoutheastern Oklahoma State University's business program has the facilities and faculty to handle an enrollment of 2,200 new students per semester. However, in an effort to limit class sizes to a "reasonable" level (under 200, generally), Southeastern's dean, Holly Lutze, placed a ceiling on enrollment of 1,500 new students. Although there was ample demand for business courses last semester, conflicting schedules allowed only 1,400 new students to take business courses. What is the utilization rate for Southeastern?

- Effective capacity is: Multiple Choice a. also called theoretical capacity. b. base capacity plus time for maintenance, breaks, and absenteeism. c. the amount of capacity that can be used in planning for actual output. d. All of these choices are correct.arrow_forwardA small firm intends to increase the capacity of a bottleneck operation by adding a new machine.Two alternatives, A and B, have been identified, and the associated costs and revenues have beenestimated. Annual fixed costs would be $40,000 for A and $30,000 for B; variable costs per unitwould be $10 for A and $11 for B; and revenue per unit would be $15.b. At what volume of output would the two alternatives yield the same profit?arrow_forwardA certain single station automated system will be used to produce three different components (A, B & C). The sales forecast for these components are A 26500, B 32500 and C 45000 units per year. Production rates for the three products are 12, 10 and 5 pc/hr and scrap rates are 22%, 16% and 17%. The plant will operate 45 weeks per year, 6 shifts per week and 8 hr per shift. It is anticipated that production machines of this type will be down for repair on average 5% of the time. How many machines will be required to meet the demand?arrow_forward
- A computer repair service has a design capacity of 80 repairs per day. Its effective capacity, however, is 64 repairs per day, and its actual output is 62 repairs per day. The manager would like to increase the number of repairs per day. Which of the following factors should the manager investigate: quality problems, absenteeism, or scheduling and balancing? Explain .arrow_forwardHow did they get 48?arrow_forwardBased on the forecasted demand from the distributors who currently buy Home-Style cookies and the projected forecast for the retail shop, Home-Style’s operations manager has determined he needs to increase the capacity of the production line. Use the following diagram of the existing four-step cookie production process to answer the following: What is the current hourly capacity of this four-step cookie production process? Which action would yield the greatest increase in hourly process capacity: 1) increase the capacity of the Mix dough step by 15%, 2) increase the capacity of the Roll dough step by 10%, or 3) increase the capacity of the Cut Cookies step by 10%. What is the new hourly capacity of this four-step cookie production process?arrow_forward
