Question
- A manufacturer produces bicycles and motorcycles, each of which must be processed through two machine centers. Machine center 1 has a maximum of 120 hours available and machine center 2 has a maximum of 180 hours available. A bicycle requires 6 hours in mc1 and 3 hours in mc2. Manufacturing a motorcycle requires 4 hours in mc1 and 10 hours in mc2. If the profit is $45 for each bicycle and $250 for a motorcycle, determine the number of bicycles and number of motorcycles to produce to maximize profit considering that the number of motorcycles must not exceed 12 units and bicycle must be at least 10 units. Formulate as Linear Program and solve using the graphical Method.

- A custom motor cycle shop is experiencing high demand from its customers for its services. The owner performs all tasks relating to customization. Assume each customer brings one motor cycle for customization. The owner needs to determine if he needs to add more help to meet customer demand. A week has 40 hours ( maximum amount of time for the owner to work) The maximum number of customizations that can be done per week is 10 bikes ( if there is no wasted time). The following is the data collected from observations for a typical week : Every Friday the shop is cleaned by the owner. This takes 4 hours. - 15 % of the customizations needs rework which takes 50 % more time than regular customization - 10 % of the customers will be called by the owner. This takes 2 hours per customer. Determine OEE. How should the owner handle the business ? Show all formulas used, calculations and results.

Out of the 100 trampolines that begin in production each month, only 75 percent pass inspection and are considered good enough to sell. The other 25 percent are scrapped due to quality problems that are identified after they have completed the production process. Each trampoline sells for $307. Each trampoline only requires 8 hours of labor because much of the process is automated. Every employee works an average of 150 hours per month. Employees are paid at $12 per hour, the materials cost is $60 per trampoline, and overhead cost is $3,500. What is the multifactor productivity ratio for Buckeye Trampoline Shop? (Enter your response rounded to one decimal place.)arrow_forwardThe first station can process a unit in 10 minutes First Station capacity = 60/10 = 6 units per hour As the second station has 2 identical machines in parallel, each of which can process a unit in 12 minutes. Each unit needs to be processed on one of the two machines. Second Station Capacity = 60 x 2/12 = 10 units per hour The third station can process a unit in 8 minutes Third Station capacity = 60/8 = 7.5 units per hour What is the hourly capacity of this production line?arrow_forward
- 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 82 percent are considered good enough to sell. The other 18 percent are scrapped due to quality problems that are identified after they have completed the production process. Each guitar sells for $240. Because some of the production process is automated, each guitar only requires 10 labor hours. Each employee works an average of 160 hours per month. Labor is paid at $10 per hour, materials cost is $40 per guitar, and overhead is $3,800. Part 2 a.

- A school is looking to hire teachers and TAs to fill its staffing needs for its summer program at minimum cost. The average monthly salary of a teacher is $2400 and the average monthly salary of a TA is $1100. The program can accommodate up to 45 staff members, needs at least 30 to run properly, and must have teachers (they will NOT employee only TAs...as much as it makes purely economic sense). They must have at least 10 TAs and may have up to 3 TA's for every 2 teachers. How many teachers and TAs the should the program hire to minimize costs. What is the minimum cost?arrow_forwardFive to six times a year, Kicker puts on tent sales in various cities throughout Oklahoma and the surrounding states. The tent sales are designed to show Kicker customers new products, engender enthusiasm about those products, and sell soon to be out-of-date products at greatly reduced prices. Each tent sale lasts one day and requires parking lot space to set up the Kicker semitrailer; a couple of show cars; a disc jockey playing music; a tent to sell Kicker merchandise, distribute brochures, and so on. Last year, the Austin, TX tent sale was held in a corner of the parking lot outside the city exhibition hall where the automotive show was in progress. Because most customers were interested more in the new model cars than in the refurbishment of their current cars, foot traffic was low. In addition, customers did not want to carry speakers and amplifiers all the way back to where they had originally parked. Total direct costs for this tent sale were $14,300.
