Question 6

You have read that in JIT and lean production the optimum lot size is one,with some exceptions for packaging and physical limitations.If a product currently has a lot size of 25,what must happen to setup time for the lot size to truly fall to one? Data for this problem are D= 100 units,S = $75 based on setup time of 50 minutes at $1.50 per minute,and H = $40 per unit per year.
