The Northridge Company tends to keep the inventory low. At the same time, it is important to respond to demand quickly, since a customer who wants a product K is very likely to get one from a competitor if Northridge Company doesn’t have one available immediately. Northridge Company’s current policy to produce the product K is to produce 100 per week, which is the average demand. Even this is a problem, as the production manager has pointed out, since the equipment is also used for other products and the lot size of 300 would be much more efficient. He said he is currently set up the production for product K for the next week and states that he has capacity available to produce 300 at a time next week. The following lists the forecasts and actual customer orders for the next 12 weeks.
