Question 5

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.

Accepted Answer

Students may try ever smaller values for

Question 6

Weekly usage of a product is 8 units. Since the plant operates 50 weeks per year, this leads to annual usage of 400 units. Setup cost is $40 and annualized carrying cost is $80. Weekly production of this product is 12 units. Lead time is four weeks, and safety stock is one week's production. What is optimal kanban size?
 What is the optimal number of kanbans?
