Revisit Problem 22 on the Bull Grin Company. Some cost and demand parameters have changed. Producing 1,000 pounds of supplement now costs $830 on regular time and $910 on overtime. No additional cost is incurred for unused regular-time, overtime, or subcontractor capacity. Overtime is limited to production of a total of 20,000 pounds per quarter. In addition, subcontractors can be hired at $1,000 per 1,000 pounds, but only 30,000 pounds per quarter can be produced this way.
The current level of inventory is 40,000 pounds, amid management wants to end the year at that level. Holding 1,000 pounds of feed supplement in inventory per quarter costs $100. The latest annual
Use the transportation method of production planning in POM for Windows to find the optimal production plan and calculate its cost, or use the spreadsheet approach to find a good production plan amid calculate its cost.

- Is my answer correct for the option b? I use the same way like in option a.arrow_forwardConsider a two-stage plant-retailer supply chain. Lead time for the plant to fill retail orders is one week. The plant produces exactly to demand and does not keep inventory. Desired safety stock at the retailer is equal to half-week demand, and future demand is estimated by the average of the past two weeks. Find the impact on plan production (customer orders) if demand permanently increases from 100 to 110 units per period.arrow_forwardRevenue Management / Yield Management is used when the following conditions exist: Uncertainty in demand and customer behavior (no-show, cancellation) + non-perishable goods Uncertainty in demand and customer behavior + backordering allowed Fixed Capacity + Perishable Inventory (hence, opportunity cost) + Advanced Booking (or sales) None of the abovearrow_forward
- A shipment of 40 pounds of fresh salmon is purchased for $4.50 per pound. The yield of the fish is 27.2 pounds after filleting. What is the yield % of the drawn salmon? What is the EP cost per pound? What is the cost for a 5-ounce portion?arrow_forwardBased on operation management perspective, please mention the advantages and disadvantages of the following figuresarrow_forwardU-RIDE, Inc. currently produces the electric engines that are used in golf carts made and sold by the Company. Electco has offered to sell the electric engines to U-RIDE at a price of $277 each. Current production information follows: Unit-level material and labor 2$ 230 Facility-level depreciation of manufacturing equip. Product-level engine production supervisor's salary Annual facility-level utilities $ 6,100/month $ 3,100/month $20,500 Buying the engines will free up manufacturing capacity that could be used to make a new economy line golf cart that would produce an additional $11,600 profit per year. U-RIDE is currently operating profitably producing and selling 3,100 engines annually. Based on this information, which of the following is true? Multiple Choice The $111,600 is not relevant because it is an estimate. Buying the units would increase U-RIDE's cost by $35 per unit. of 10arrow_forward
- Demand for stereo headphones and music players for joggers has caused Nina Industries to grow almost 50 percent over the past year. The number of joggers continues to expand, so Nina expects demand for headsets to also expand, because, as yet, no safety laws have been passed to prevent joggers from wearing them. Demand for the players for this year was as follows: MONTH DEMAND (UNITS) January 4,150 February 4,250 March 3,950 April 4,350 May 4,950 June 4,650 July 5,250 August 4,850 September 5,350 October 5,650 November 6,250 December 5,950 a. Using linear regression analysis, what would you estimate demand to be for each month next year? Using a spreadsheet, follow the general format in Exhibit 3.8. (Do not round intermediate calculations. Round your answers to 2 decimal places.) b. To be reasonably confident of meeting demand, Nina decides to use 3 standard errors of estimate for safety. How many additional units should be held to meet this…arrow_forwardDevelop a production plan and calculate the annual cost for a firm whose demand forecast is fall, 11,000; winter, 8,000; spring, 6,000; summer, 13,000. Inventory at the beginning of fall is 500 units. At the beginning of fall you currently have 30 workers, but you plan to hire temporary workers at the beginning of summer and lay them off at the end of summer. In addition, you have negotiated with the union an option to use the regular workforce on overtime during winter or spring if overtime is necessary to prevent stockouts at the end of those quarters. Overtime is not available during the fall. Relevant costs are hiring, $100 for each temp; layoff $200 for each worker laid off; inventory holding, $5 per unit-quarter; backorder, $10 per unit; straight time, $5 per hour; overtime, $8 per hour. Assume that the productivity is 0.5 unit per worker hour, with eight hours per day and 60 days per season. a. What is the total cost for this plan?arrow_forwardAn automobile company has two versions of the same model car for sale, a two-door coupe and full-size four doors.

The monthly output per employee is 100 units. The costs to hire and lay off a worker are $2,000 and $3,000, respectively.
