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 in Figure. Raw materials and purchased parts (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 work 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…
The MacJunkin Company manufactures transmission parts. The current process uses 20 workers and produces 400 units per hour. You are considering changing the process with new manufacturing methods that increase output to 470 units per hour but will require 22 workers. Workers are paid at a rate of $15 per hour, and overhead is charged at 140% (or 1.4 times) labor costs. Finished switches sell for $80/unit. The details are as follows:

Three years after, this company still rents designer dresses to customers, but it has managed to streamline its internal processes and expand to different segments of demand. Now, customers can rent clothes for anywhere between 1 days to 30 days, and each customer is sent only one (1) dress (instead of 2 dresses described in the case). The company alsó takes only 13 number of days to turn around a dress (i.e., this the duration starting with return from a customer, to again being rented out to a customer). The current demand is an average of 1,000 customers per day, and the company owns total of 30 thousand dresses. What is the average rental duration?

- The Goodparts Company produces a component that is subsequently used in the aerospace industry. The component consists of three parts (A, B, and C) that are purchased from outside and cost 35, 30, and 10 cents per piece, respectively. Parts A and B are assembled first on assembly line 1, which produces 185 components per hour. Part C undergoes a drilling operation before being finally assembled with the output from assembly line 1. There are, in total, six drilling machines, but at present only three of them are operational. Each drilling machine drills part C at a rate of 80 parts per hour. In the final assembly, the output from assembly line 1 is assembled with the drilled part C. The final assembly line produces at a rate of 205 components per hour. At present, components are produced eight hours a day and five days a week. Management believes that if the need arises, it can add a second shift of eight hours for the assembly lines. The cost of assembly labor is 30 cents per part for…arrow_forwardMotorking Corporation, a market leader in the production of specialized engine additives, is considering introducing a new "gas extender" product. This product is added to an automobile’s gasoline to extend mileage and reduce exhasut emissions. Motorking's manufacturing facility can produce 50,000 cases of the new product per year with a set-up cost of $100,000. The average variable cost per case would be $5. Large orders, (i.e., above 50,000 cases) will be subcontracted to a local refining company. Motorking has signed a secrecy agreement with the vendor that guards the basic process. The variable cost per case, if the new product is produced outside, is $9. Whether the product is manufactured by Motorking or by the vendor, there is a $12 per case cost for marketing and overhead. Motorking's production manager is considering three production levels for the new product: 50,000 cases, 75,000 cases, and 100,000 cases. The level of sales will depend on the state of the economy.
