Problem 4 Frank’s Fine Furniture makes tables, desks, bookcases, and other office furniture. At the North California facility, they make tables. All parts of the table are purchased except for the tabletop that is fabricated at the plant. Tables are made to order for dealers who FAX orders into the sales department. Orders are processed from the order database on FIFO basis. The first step in the process is to cut the top ¾ pressboard. It takes one worker 20...

Adam (with the same machine) performs tasks 1 and 2. After
running a setup on the machine, he performs task 1 on every unit in
a batch. Then, he runs another setup on the same machine before
performing task 2 on every unit in the batch. After that, either
Brad or Chloe performs task 3 on the units. Finally, Dorothee does
task 4. Tasks 3 and 4 are done by the workers only so they do not
require any setups....

It takes 3 minutes to load and 2 minutes to unload a machine. Inspection and packing times total 1 minute; travel between machines takes 2 minutes. Machines run automatically for 20 minutes. Operators cost $10 per hour; machines cost $30 per hour. Document all answers completely. Suppose 12 machines are needed to meet the production requirement. a) Which of the following assignments will minimize the total cost: {4, 4, 4} or {3, 4, 5}? b) Is there another combination that...

An order for 200 of a product is processed on operation A and operation B. The setup time on A is 100 minutes, and the run time per piece is 18 minutes. The setup time on B is 60 minutes, and the run time is 12 minutes per piece. It takes 30 minutes to move a lot between A and B. Since this is a rush order, it is given top priority (president’s edict) and is run as soon as...

a) A workpiece (φ-75 mm, 1 275 mm) is machined using turning at a feed rate of 0.25 mm/rev. At a cutting speed- 3.5 m/s, the turning tool is ineffective after machining 3 parts, and at a cutting speed = 2.5 m/s, the turning tool is effective for producing 20 parts. Calculate the Cutting Speed that will allow 30 parts to be machined between tool changes [20 marks] b) An aluminium alloy workpiece (tensile strength - 325 N/mm2 and yield...
