A metal fabrication shop has a single punch press. There are 3 parts that the shop has agreed to produce that require the same press. The relevant information about the 3 products are as follows: i = 18% annually and setup time can be considered negligible. The products will be produced in sequence on a rotational cycle. What is the optimal time between setups? What is the optimal number of orders per year? What is the optimal lot sizes of each part? What is the difference in total annual cost of holding und setup for these items on the punch press if produced individually or in rotation cycle
