Writing Errands

“Metal window boxes are manufactured in two process steps: stamping and assembly. Each window box is made of 3 pieces: base A and two side Bs. These parts are fabricated by a stamping machine with a setup time of 2 hours whenever switching between the two part types. Once the machine is set up, the activity time for part A is one minute and for part B is 30 seconds. The current rotation is 360 As to 720 Bs. Completed parts move from stamping to assembly once a batch is complete. At assembly, one A, two Bs and some purchased parts are required per finished unit. Each product requires 27 minutes of labor to assemble; there are 12 workers in assembly; there is sufficient demand to sell every box produced.1) What’s the capacity at stamping?2)What should the batch size be?”
